Use this skill when the user asks to build web components, pages, or applications. Generates creative, polished code that avoids generic AI aesthetics.\nlicense: Complete terms in LICENSE.txt\n---\n\nThis skill guides creation of distinctive, production-grade frontend interfaces that avoid generic \"AI slop\" aesthetics. Implement real working code with exceptional attention to aesthetic details and creative choices.\n\nThe user provides frontend requirements: a component, page, application, or interface to build. They may include context about the purpose, audience, or technical constraints.\n\n## Design Thinking\n\nBefore coding, understand the context and commit to a BOLD aesthetic direction:\n- **Purpose**: What problem does this interface solve? Who uses it?\n- **Tone**: Pick an extreme: brutally minimal, maximalist chaos, retro-futuristic, organic/natural, luxury/refined, playful/toy-like, editorial/magazine, brutalist/raw, art deco/geometric, soft/pastel, industrial/utilitarian, etc. There are so many flavors to choose from. Use these for inspiration but design one that is true to the aesthetic direction.\n- **Constraints**: Technical requirements (framework, performance, accessibility).\n- **Differentiation**: What makes this UNFORGETTABLE? What's the one thing someone will remember?\n\n**CRITICAL**: Choose a clear conceptual direction and execute it with precision. Bold maximalism and refined minimalism both work - the key is intentionality, not intensity.\n\nThen implement working code (HTML/CSS/JS, React, Vue, etc.) that is:\n- Production-grade and functional\n- Visually striking and memorable\n- Cohesive with a clear aesthetic point-of-view\n- Meticulously refined in every detail\n\n## Frontend Aesthetics Guidelines\n\nFocus on:\n- **Typography**: Choose fonts that are beautiful, unique, and interesting. Avoid generic fonts like Arial and Inter; opt instead for distinctive choices that elevate the frontend's aesthetics; unexpected, characterful font choices. Pair a distinctive display font with a refined body font.\n- **Color & Theme**: Commit to a cohesive aesthetic. Use CSS variables for consistency. Dominant colors with sharp accents outperform timid, evenly-distributed palettes.\n- **Motion**: Use animations for effects and micro-interactions. Prioritize CSS-only solutions for HTML. Use Motion library for React when available. Focus on high-impact moments: one well-orchestrated page load with staggered reveals (animation-delay) creates more delight than scattered micro-interactions. Use scroll-triggering and hover states that surprise.\n- **Spatial Composition**: Unexpected layouts. Asymmetry. Overlap. Diagonal flow. Grid-breaking elements. Generous negative space OR controlled density.\n- **Backgrounds & Visual Details**: Create atmosphere and depth rather than defaulting to solid colors. Add contextual effects and textures that match the overall aesthetic. Apply creative forms like gradient meshes, noise textures, geometric patterns, layered transparencies, dramatic shadows, decorative borders, custom cursors, and grain overlays.\n\nNEVER use generic AI-generated aesthetics like overused font families (Inter, Roboto, Arial, system fonts), cliched color schemes (particularly purple gradients on white backgrounds), predictable layouts and component patterns, and cookie-cutter design that lacks context-specific character.\n\nInterpret creatively and make unexpected choices that feel genuinely designed for the context. No design should be the same. Vary between light and dark themes, different fonts, different aesthetics. NEVER converge on common choices (Space Grotesk, for example) across generations.\n\n**IMPORTANT**: Match implementation complexity to the aesthetic vision. Maximalist designs need elaborate code with extensive animations and effects. Minimalist or refined designs need restraint, precision, and careful attention to spacing, typography, and subtle details. Elegance comes from executing the vision well.\n\nRemember: Claude is capable of extraordinary creative work. Don't hold back, show what can truly be created when thinking outside the box and committing fully to a distinctive vision."}],"isError":false,"timestamp":1781078130842}} {"type":"message","id":"c575d9f4","parentId":"eae7582f","timestamp":"2026-06-10T07:56:04.260Z","message":{"role":"assistant","content":[{"type":"thinking","thinking":"用户要求创建一个离线静态网页，使用WASM做一个简单的Python解释器。我需要：\n\n1. 使用Pyodide（一个流行的Python WASM实现）- 它可以从CDN加载，也可以离线使用\n2. 创建一个美观、适配移动端和电脑端的界面\n3. 可以执行简单的Python代码\n\n根据frontend-design skill的指导，我需要：\n- 选择一个独特的设计方向\n- 使用独特的字体\n- 有创意的布局和交互\n\n对于Python解释器，我可以选择一个\"终端/复古科技\"或者\"现代暗色编辑器\"风格。让我设计一个独特的、精致的界面。\n\n让我创建一个项目目录，然后构建HTML文件。\n\n我决定使用以下设计：\n- 深色主题，带有一些微妙的纹理\n- 类似终端的编辑器，但更加现代和精致\n- 使用Cascadia Code或类似等宽字体作为代码字体\n- 使用一个独特的衬线字体作为标题\n- 代码输入区和输出区\n- 运行按钮\n- 响应式设计\n\n我会用Pyodide（通过CDN加载），这样用户可以直接在浏览器中运行Python。\n\n让我直接创建这个文件。","thinkingSignature":"reasoning_content"},{"type":"text","text":"好的！我来创建一个精美的离线静态网页，使用 WASM 实现 Python 解释器。"},{"type":"toolCall","id":"functions.write:1","name":"write","arguments":{"path":"/shumengya/www/python-wasm/index.html","content":"\n\n\n \n \n Python 解释器\n \n \n \n\n\n \n

Let me analyze:\n\n1. **404 Error**: The WASM files are returning 404. Let me check the file structure. The HTML references `pyodide/pyodide.min.js` but the `loadPyodide({ indexURL: 'pyodide/' })` is trying to load the `.wasm` file from there. Let me check if the files are actually in the right place and what URLs are being requested.\n\n2. **JS Error**: `Cannot set properties of null (setting 'textContent')` at line 724. Looking at the initPyodide error handler:\n```javascript\n} catch (err) {\n document.getElementById('loadingText').textContent = '加载失败';\n document.querySelector('.loading-subtext').textContent = err.message;\n console.error('Pyodide init error:', err);\n}\n```\n\nThe `.loading-subtext` class doesn't exist! The element is `loading-subtext` as an ID, not a class. Wait, looking at the HTML:\n```html\n

\n```\n\nBoth have `class` not `id`. The JavaScript uses `document.getElementById('loadingText')` and `document.querySelector('.loading-subtext')`.\n\nWait, looking more carefully:\n- `document.getElementById('loadingText')` - but the HTML has `class=\"loading-text\"` not `id=\"loadingText\"`. This would be null!\n- `document.querySelector('.loading-subtext')` - this should work since it has `class=\"loading-subtext\"`.\n\nSo the error is `document.getElementById('loadingText')` is null because `loadingText` doesn't exist as an ID, it's a class.\n\nLet me check the file structure and fix both issues.\n\nAlso, the 404 for WASM files might be because:\n1. The python stdlib server doesn't serve WASM files with the right MIME type\n2.

The `locateFile` is set to:\n\n```\nlocateFile=s=>o.indexURL+s\n```\n\nBut wait, the `pyodide.asm.js` might be trying to load the WASM file using `locateFile`. Let me check if the `pyodide.asm.js` actually uses `locateFile` or if it uses a different mechanism.\n\nActually, looking at the `pyodide.asm.js` output earlier:\n```\nwasmBinaryFile=\"pyodide.asm.wasm\";if(!isDataURI(wasmBinaryFile\n```\n\nThis is the Emscripten-generated code. It sets `wasmBinaryFile` to the filename. But Emscripten also has a `locateFile` function that is used to resolve the path. If `locateFile` is set correctly, it should work.\n\nBut wait, the `loadPyodide` function sets `locateFile` after the `pyodide.asm.js` is loaded. The `pyodide.asm.js` might be loading the WASM file before `locateFile` is set.\n\nLet me check the actual loading sequence. In `pyodide.min.js`:\n```javascript\nlet s = `${o.indexURL}pyodide.asm.js`;\nawait S(s);\nif (await _createPyodideModule(a), ...)\n```\n\nSo `pyodide.asm.js` is loaded first, then `_createPyodideModule(a)` is called. The `a` object might contain `locateFile`. Let me check if `a` is the module object that is passed to `_createPyodideModule`.\n\nIn Emscripten, the module object is passed to the factory function. The `locateFile` is a property of the module object. So if `locateFile` is set correctly in the module object, it should work.\n\nBut the issue might be that `pyodide.asm.js` is loaded via `import()`, and the `import()` function loads the module in a different way. The `import()` function might execute the script but not set the module object correctly.\n\nActually, looking at the `pyodide.asm.js` code:\n```javascript\nvar _createPyodideModule = (() => {\n var _scriptDir = typeof document !== 'undefined' && document.currentScript ? document.currentScript.src : undefined;\n```\n\nThis is a factory function. It returns `_createPyodideModule`. When loaded via `import()`, the `import()` call would return the module's exports. But `pyodide.asm.js` is not a module, so it might not have any exports. But the `import()` call might still work because the script defines a global variable.\n\nWait, but the code says:\n```javascript\nif (typeof _createPyodideModule != \"function\") {\n let s = `${o.indexURL}pyodide.asm.js`;\n await S(s);\n}\n```\n\nThis checks if `_createPyodideModule` is already defined. If not, it loads the script. After loading the script, `_createPyodideModule` should be defined as a global variable.\n\nThen:\n```javascript\nawait _createPyodideModule(a)\n```\n\nThis calls the factory function with the module object `a`.\n\nThe module object `a` should contain `locateFile`. Let me check if `locateFile` is set correctly.\n\nLooking at the pyodide.min.js:\n```\nlocateFile=s=>{throw new Error(\"Didn't expect to load any more file_packager files!\")}\n```\n\nThis is the `locateFile` for the package files. But the WASM file is loaded via Emscripten's own mechanism.\n\nActually, let me look more carefully. The `locateFile` for the WASM file might be set differently. Let me check the Emscripten code in `pyodide.asm.js`.","thinkingSignature":"reasoning_content"},{"type":"toolCall","id":"functions.bash:72","name":"bash","arguments":{"command":"# Search for locateFile in pyodide.asm.js\ngrep -oP '.{0,40}locateFile.{0,40}' /shumengya/www/python-wasm/pyodide/pyodide.asm.js | head -10"}}],"api":"openai-completions","provider":"opencode-go-openai","model":"kimi-k2.6","usage":{"input":660,"output":963,"cacheRead":58979,"cacheWrite":0,"totalTokens":60602,"cost":{"input":0.000627,"output":0.003852,"cacheRead":0.00943664,"cacheWrite":0,"total":0.01391564}},"stopReason":"toolUse","timestamp":1781080099684,"responseId":"chatcmpl-e10d5cf6308242288493153a284fd466","responseModel":"accounts/fireworks/models/kimi-k2p6"}} {"type":"message","id":"f69a7321","parentId":"96afb716","timestamp":"2026-06-10T08:28:26.332Z","message":{"role":"toolResult","toolCallId":"functions.bash:72","toolName":"bash","content":[{"type":"text","text":"_WORKER;var scriptDirectory=\"\";function locateFile(path){if(Module[\"locateFile\"]){return M\nodule[\"locateFile\"](path,scriptDirectory)}return scriptDi\nDataURI(wasmBinaryFile)){wasmBinaryFile=locateFile(wasmBinaryFile)}function getBinarySync(\nse.resolve(libData):libData}var libFile=locateFile(libName);if(flags.loadAsync){return new\n"}],"isError":false,"timestamp":1781080106332}} {"type":"message","id":"a01fe1f9","parentId":"f69a7321","timestamp":"2026-06-10T08:28:33.220Z","message":{"role":"assistant","content":[{"type":"thinking","thinking":"Now I see the issue!

`TypeError: Cannot set properties of null (setting 'textContent')`（后一个已修复，前一个仍在排查）\n- 404 文件尚不明确：可能是 `pyodide.asm.js` 通过 `import()` 加载后，`document.currentScript` 为 null，导致 `scriptDirectory` 为空，相对路径 `pyodide.asm.wasm` 被解析为根目录而非 `pyodide/` 目录\n\n## Key Decisions\n- **使用 Pyodide 0.25.1**：通过 `pyodide.min.js` + `pyodide.asm.js` + `pyodide.asm.wasm` + `python_stdlib.zip` + `pyodide-lock.json` 实现离线运行\n- **`loadPyodide` 使用 `indexURL: 'pyodide/'`**：理论上 `locateFile` 会被正确设置，但 `pyodide.asm.js` 通过 `import()` 动态加载时 `document.currentScript` 为 null，路径解析可能出问题\n- **输出捕获**：使用 Python `io.StringIO` + `sys.stdout` 重定向捕获 `print` 输出\n\n## Next Steps\n1. **确定 404 的具体 URL**：在浏览器网络面板中查看到底是哪个文件 404（可能是 `pyodide.asm.wasm` 被解析到了根目录）\n2. **验证修复方案**：尝试将 `indexURL: 'pyodide/'` 改为绝对路径（如 `location.origin + '/pyodide/'`），或改用 `\n \n \n \n \n \n \n\n \n

Done\n- [x] 创建 `/shumengya/www/python-wasm/index.html`（单文件 HTML，含 Pyodide 交互界面）\n- [x] 响应式布局（桌面端左右分栏，移动端上下分栏）\n- [x] 删除所有 Emoji（面板标题、运行按钮）\n- [x] 修改 `runCode()`：每次执行前清空输出框，只输出结果/错误\n- [x] 下载 Pyodide WASM 文件到本地 `pyodide/` 目录\n- [x] 替换 CDN 引用为本地路径 `pyodide/pyodide.min.js`\n- [x] 设置 `loadPyodide({ indexURL: './pyodide/' })`\n- [x] 修复 JS 错误：`document.getElementById('loadingText')` →

Worker 缓存（sw.js）\n- [x] 静态资源 30 天缓存\n- [x] 对比 CDN 版本和本地 nginx 版本（给了用户选择建议）\n- [x] 创建 Go WASM 编译器 `/shumengya/www/go-wasm/`\n - [x] 下载 yaegi v0.14.3（Go 1.19 兼容）\n - [x] 编译 Go 解释器到 WASM（34MB → gzip 后

WASM 编译器（正在手写简化版 JS C 编译器）\n - [ ] 词法分析器\n - [ ] 语法分析器\n - [ ] WASM 代码生成器\n - [ ] 前端页面\n\n### Blocked\n- cib 项目依赖的 wasm-ld.wasm 和 sysroot.tar 无法下载（404 页面）\n- yaegi v0.16.1 不支持 Go 1.19 WASM 编译（需要降级到 v0.14.3，已解决）\n- GitHub API 限流，无法获取 release 信息\n\n## Key Decisions\n- **Python 解释器从 8765 端口迁移到 31002 端口**：使用 nginx + gzip 压缩，WASM 从 8.6MB 压缩到 2.75MB，JS 从 1.1MB 压缩到 202KB\n- **使用 yaegi v0.14.3 而非 v0.16.1**：Go 1.19.8 环境不支持 v0.16.1 的 `stdlib/generic` 构建约束\n- **Go 编译器使用 31003 端口**：nginx 配置 gzip，WASM 34MB gzip 后 7.3MB\n- **C/C++ 编译器放弃完整 Clang 方案**：cib 的 wasm-ld 和 sysroot 无法下载，改为手写简化版 JS C 编译器\n- **手写 C 编译器策略**：支持 int 变量、表达式、if/else、while/for、printf、return，生成 WASM 二进制\n\n## Next Steps\n1. 完成手写 C 编译器（Tokenizer + Parser + CodeGen + WasmGen）\n2. 创建 C 编译器前端页面\n3. 配置 nginx 31004 端口\n4. 测试 C 编译器运行简单代码\n\n## Critical Context\n- **Python 解释器**：`http://192.168.1.100:31002`\n - 主文件：`/shumengya/www/python-wasm/index.html`\n - Pyodide 目录：`/shumengya/www/python-wasm/pyodide/`\n - nginx 配置：`/www/server/panel/vhost/nginx/python-wasm.conf`\n- **Go 编译器**：`http://192.168.1.100:31003`\n - 主文件：`/shumengya/www/go-wasm/index.html`\n - WASM 文件：`/shumengya/www/go-wasm/go-runner.wasm` (34MB)\n - JS 运行时：`/shumengya/www/go-wasm/wasm_exec.js`\n - 源码：`/shumengya/www/go-wasm/src/main.go`\n - nginx 配置：`/www/server/panel/vhost/nginx/go-wasm.conf`\n- **C/C++ 编译器**：\n - 目标路径：`/shumengya/www/c-wasm/`\n - 目标端口：31004\n - cib 的 clang.wasm 已下载到 `/tmp/cib-test/clang.wasm`（30MB 有效），但缺少 wasm-ld 和 sysroot，无法直接使用\n - 当前方案：手写 JS C 编译器，生成 WASM 二进制\n- **nginx 状态**：`192.168.1.100:31002` 和 `31003` 已监听，配置通过 `nginx -t` 测试\n- **服务器**：nginx 已重载，端口 31002 和 31003 正常\n- **Go 版本**：`go version go1.19.8 linux/amd64`\n- **Go 环境变量**：`GOPATH=/root/go`, `GOMODCACHE=/root/go/pkg/mod`, `GOCACHE=/root/go/cache`\n\n---\n\n**Turn Context (split turn):**\n\n## Original Request\n用户要求寻找一个现成的 C 编译器 WASM 项目，以便在浏览器中运行，避免自己从零实现。\n\n## Early Progress\n- 在 GitHub 上搜索并评估了多个候选项目，最终选择了 **tyfkda/xcc**（支持 wasm 目标的独立 C 编译器）。\n- 下载并分析了 xcc 的在线演示资源：\n - `wccfiles.zip` (141KB)：包含 `usr/bin/cc` (292KB WASM 编译器)、C 标准头文件、`usr/lib/wcrt0.a` 和 `usr/lib/wlibc.a` (67KB 标准库)。\n - `wasi_worker.js` (182KB)：内嵌完整 WASI 运行时和 memfs 的 Web Worker。\n- 创建了首个 `index.html` 前端页面（位于 `/shumengya/www/c-wasm/`），但发现缺少前端 zip 解压实现。\n- 决定重新设计：改为预解压 zip 文件到网站目录，让 Worker 直接加载文件，避免在浏览器中解压。\n\n## Context for Suffix\n- 已确认 `usr/bin/cc` 是实际的 WASM 编译器，头文件和库已就位。\n- 需要解决的核心问题：如何让 `wasi_worker.js` 与预解压的文件配合，以及重写前端代码来完成编译→运行流程。\n\n\n/shumengya/project/agent/sproutclaw/.pi/agent/skills/frontend-design/SKILL.md\n/www/server/panel/vhost/nginx/html_192.168.1.100_2525.conf\n\n\n\n/shumengya/www/c-wasm/index.html\n/shumengya/www/go-wasm/index.html\n/shumengya/www/go-wasm/src/main.go\n/shumengya/www/python-wasm/index.html\n/shumengya/www/python-wasm/sw.js\n/www/server/panel/vhost/nginx/go-wasm.conf\n/www/server/panel/vhost/nginx/python-wasm.conf\n","firstKeptEntryId":"849b43a8","tokensBefore":174446,"details":{"readFiles":["/shumengya/project/agent/sproutclaw/.pi/agent/skills/frontend-design/SKILL.md","/www/server/panel/vhost/nginx/html_192.168.1.100_2525.conf"],"modifiedFiles":["/shumengya/www/c-wasm/index.html","/shumengya/www/go-wasm/index.html","/shumengya/www/go-wasm/src/main.go","/shumengya/www/python-wasm/index.html","/shumengya/www/python-wasm/sw.js","/www/server/panel/vhost/nginx/go-wasm.conf","/www/server/panel/vhost/nginx/python-wasm.conf"]},"fromHook":false}

Code generation is done by emitting a high-level assembly (currently very ugly C, but LLVM/cretone/GIMPLE/... could work) and getting an external tool (i.e. `gcc`) to do the heavy-lifting of optimising and machine code generation.\n\nProgress\n--------\n\n- Builds working copies of `rustc` and `cargo` from a release source tarball\n - Currently tested to fully bootstrap (with a binary-equal 1.91.1) version 1.90.0\n - Slso supports and might still bootstrap (assuming the right environment) - rustc 1.19.0, 1.29.0, 1.39.0, 1.54.0, 1.74.0\n - NOTE: Older versions (1.29 and older) don't build on modern systems, due to outdated openssl bindings\n- Supported Targets (CI tested for libstd):\n - x86-64 linux GNU (Specifically Debian/Ubuntu; should always work, fully bootstrap tested)\n - x86-64 windows MSVC (Status: runnable executables on Windows 10, but bootstrap hasn't ever been fully tested)\n - Secondary Targets\n - x86-64 and arm64 macOS\n - (incomplete) x86 windows MSVC\n- `rustc` bootstrap tested and validated (1.19.0 isn't fully repeatable, but later versions are)\n - See the script `TestRustcBootstrap.sh` for how this was done.\n\n\n"}],"isError":false,"timestamp":1781110665536}} {"type":"message","id":"7b0711b6","parentId":"69791205","timestamp":"2026-06-10T16:57:50.232Z","message":{"role":"assistant","content":[{"type":"thinking","thinking":"mrustc 是 C++ 写的，不是编译到 WASM 的。让我搜索其他方案。\n\n实际上，有一个很有希望的项目：Rust Playground 的 WASM 编译器，或者 `cranelift` 的 WASM 编译。\n\n让我搜索一下有没有现成的 Rust 编译器 WASM 项目。","thinkingSignature":"reasoning_content"},{"type":"toolCall","id":"functions.bash:179","name":"bash","arguments":{"command":"export http_proxy=http://192.168.1.1:17892\nexport https_proxy=http://192.168.1.1:17892\n\n# 搜索几个关键项目\n# 1. rust-play 的 wasm 版本\n# 2. 搜索 \"rustc wasm\" 相关项目\n\n# 搜索 github 上的 wasm-rust 相关项目\ncurl -s \"https://api.github.com/search/repositories?q=rust+compiler+wasm+in+browser&per_page=5\" | python3 -c \"\nimport sys, json\ndata = json.load(sys.stdin)\nfor item in data.get('items', []):\n print(f'{item['full_name']}: {item['description'][:80]}')\n print(f' Stars: {item['stargazers_count']}, URL: {item['html_url']}')\n print()\n\"\n","timeout":30}}],"api":"openai-completions","provider":"opencode-go-openai","model":"kimi-k2.6","usage":{"input":778,"output":278,"cacheRead":38089,"cacheWrite":0,"totalTokens":39145,"cost":{"input":0.0007390999999999999,"output":0.001112,"cacheRead":0.00609424,"cacheWrite":0,"total":0.00794534}},"stopReason":"toolUse","timestamp":1781110665537,"responseId":"chatcmpl-7a1ef3024e3548578c4e31fb96ce95bd","responseModel":"accounts/fireworks/models/kimi-k2p6"}} {"type":"message","id":"09a6157b","parentId":"7b0711b6","timestamp":"2026-06-10T16:57:50.867Z","message":{"role":"toolResult","toolCallId":"functions.bash:179","toolName":"bash","content":[{"type":"text","text":"use-ink/ink-playground: Browser Based Playground for editing, sharing & compiling ink!

There are numerous bugs, such as commands throwing errors and subsequently becoming unusable, but feel free to open issues if necessary. Minor pull requests to improve usability are also welcome, so feel free to tweak it as you like.\n\n# Features\n! This project require coop coep headers to work, so you need to run it on a server or use a browser extension to allow it.\n- [x] Run rustc on the browser\n- [x] Ctrl+V \n\n# Funding\nThe projects that this project depends on, namely [browser_wasi_shim-threads](https://www.npmjs.com/package/@oligami/browser_wasi_shim-threads), [rust_wasm](https://github.com/oligamiq/rust_wasm), and [shared-object](https://www.npmjs.com/package/@oligami/shared-object), are all my projects. The [toolchain-for-building-rustc](https://github.com/oligamiq/toolchain-for-building-rustc) that rust_wasm depends on is also my project. I was the one who enabled the LLVM backend for rustc, and ultimately, I aim to make rustc executable in browsers that support wasm and allow cargo to run seamlessly on the web.\n\nIf you like or want to use this series of projects, I would appreciate it if you could contribute financially via the sponsor button.\n\nPlease note that coding has temporarily stopped due to being busy, and there may be missing or incorrect documentation. Although it works, it is currently in a state with various issues, so I do not recommend using it for production.\n\n# License\nThis project is licensed under the MIT OR Apache-2.0 License.\n"}],"isError":false,"timestamp":1781110675894}} {"type":"message","id":"3cf4db82","parentId":"bedc44f5","timestamp":"2026-06-10T16:57:59.948Z","message":{"role":"assistant","content":[{"type":"thinking","thinking":"找到了一个非常合适的项目：`rubrc` (Rust compiler that runs in the browser!)。\n\n它已经把 rustc 编译为 WASM，并且有一个在线演示：https://oligamiq.github.io/rubrc/\n\n让我访问这个演示页面看看，了解它的资源需求，然后尝试下载。\n\n这个项目说：\n- 需要 coop coep headers (Cross-Origin-Opener-Policy 和 Cross-Origin-Embedder-Policy)\n- 支持 wasm32-wasip1 和 x86_64-unknown-linux-musl 目标\n- 需要 browser_wasi_shim-threads 和 rust_wasm\n\n让我先访问 demo 页面看看需要什么资源。","thinkingSignature":"reasoning_content"},{"type":"toolCall","id":"functions.bash:181","name":"bash","arguments":{"command":"export http_proxy=http://192.168.1.1:17892\nexport https_proxy=http://192.168.1.1:17892\n\n# 访问 rubrc demo 页面，看看资源\n# 先看看页面内容\ncurl -sL \"https://oligamiq.github.io/rubrc/\" | head -30\n\n# 查看页面资源\ncurl -sL \"https://oligamiq.github.io/rubrc/\" | grep -o 'src=\"[^\"]*\"' | head -20\ncurl -sL \"https://oligamiq.github.io/rubrc/\" | grep -o 'href=\"[^\"]*\"' | head -20\n","timeout":30}}],"api":"openai-completions","provider":"opencode-go-openai","model":"kimi-k2.6","usage":{"input":1340,"output":311,"cacheRead":39378,"cacheWrite":0,"totalTokens":41029,"cost":{"input":0.0012729999999999998,"output":0.0012439999999999999,"cacheRead":0.00630048,"cacheWrite":0,"total":0.008817479999999999}},"stopReason":"toolUse","timestamp":1781110675895,"responseId":"chatcmpl-0fe0c680397f471480ae1071dc140ea3","responseModel":"accounts/fireworks/models/kimi-k2p6"}} {"type":"message","id":"b06e73bd","parentId":"3cf4db82","timestamp":"2026-06-10T16:58:01.464Z","message":{"role":"toolResult","toolCallId":"functions.bash:181","toolName":"bash","content":[{"type":"text","text":"\n\n \n \n \n \n \n Rubrc\n \n \n \n \n \n \n

This is the latest status I believe: Compilation to WASM? | Keeping up with WASM developments | 2 | 1391 | March 25, 2019 |. | Moving WebAssembly support forward compiler | 42 | 8442 | March 25, 2019 |. | How close are we to having rustc.wasm? compiler | 5 | 1703 | March 25, 2019 |.","score":0.78154784,"raw_content":null},{"url":"https://www.reddit.com/r/rust/comments/n27cjb/can_the_rust_compiler_be_compiled_to_wasm_and_run","title":"Can the Rust compiler be compiled to WASM and run on a browser?","content":"Would it be too difficult to compile the Rust compiler to WASM so that it can run on an embedded web view?","score":0.6369636,"raw_content":null},{"url":"https://towardsdatascience.com/nine-rules-for-running-rust-in-the-browser-8228353649d1","title":"Nine Rules for Running Rust in the Browser | Towards Data Science","content":"# Nine Rules for Running Rust in the Browser.

It’s usually compiled from another language like Go, Rust, or C++, and it gives you a secure sandbox that is often much more performant than executing JavaScript in the browser. Using a runtime library you can host a WebAssembly binary and call it from the host language. It’s the same principle as calling WebAssembly from JS in the browser, except you can do it from Rust or Go or Python.

Enter WebAssembly (or WASM for short), supported by a wide consortium of players, developed in the open and as an open standard, with the WEB as its primary platform. While it’s too early to tell if WebAssembly will be the winner we’ve been waiting for, its adoption is wide enough, the core technology is stable enough that it’s worth considering it for even professional cases. So in this guide we’ll walk through setting up the tooling and development environment for building and using WebAssembly in Rust, embedding it in a TypeScript project, review how communication between TypeScript and Rust can happen, then finally how you can debug your WebAssembly directly in the browser and/or your favorite IDE.","score":0.5101799,"raw_content":null},{"url":"https://sendilkumarn.com/blog/rustwasm-introduction","title":"Rust and WebAssembly - Introduction","content":"WebAssembly makes it easy to run native code in the browser.

In this tutorial, we’ll guide you through the step-by-step process of deploying a Rust WebAssembly (WASM) app on GitHub Pages. The final website will consist of a JavaScript frontend that utilizes WASM, generated from Rust code. * `wasm-bindgen` generates `.wasm` and glue JS files. * `wasm-pack` generates JS files intended to be imported from JS using `wasm-bindgen`. * `wasm-pack` can generate files suitable for bundlers like `webpack`. Let’s begin by adding wasm-bindgen, a tool that handles the interaction between Rust and JavaScript, to the `Cargo.toml` file:. To build the file for the WASM app, we’ll use wasm-pack, a tool covering from building Rust to generating a package to be published to `npm`, though We won’t publish our package in this post. ## wasm-pack and webpack#.

I put both, the client-side frontend and the server-side backend, into one repository for maintainability.

To keep maintenance manageable, Miri only supports running on platforms that rustc supports running on.*. Compiling the whole Rustc to WASM is a pretty big undertaking for many reasons. However, Miri doesn't need an actual codegen and many other parts of the whole Rustc, so I wonder how realistic it would be to compile it and the pieces it depends on to WASM instead? P.S. Despite what I said in the first sentence, this was actually done for Clang a while ago - - which includes LLVM compiled to WASM that, in turn, generates more WASM dynamically during runtime. In theory, it should be possible to do the same for Rust, especially since they share LLVM, but for now having just an interpreter could already be an interesting starting goal. ### Footer navigation.","score":0.16234049,"raw_content":null},{"url":"https://www.youtube.com/watch?v=shy9DYpoHtQ","title":"Introduction to WebAssembly (WASM) with Rust and WASMEdge","content":"...

It’s clear WebAssembly is one of the more popular up-and-coming technologies out there. While it can run on most systems now, the web is still not one of them. Enter WebAssembly (or WASM for short), supported by a wide consortium of players, developed in the open and as an open standard, with the WEB as its primary platform. While it’s too early to tell if WebAssembly will be the winner we’ve been waiting for, its adoption is wide enough, the core technology is stable enough that it’s worth considering it for even professional cases.

It’s clear WebAssembly is one of the more popular up-and-coming technologies out there. While it can run on most systems now, the web is still not one of them. Enter WebAssembly (or WASM for short), supported by a wide consortium of players, developed in the open and as an open standard, with the WEB as its primary platform. While it’s too early to tell if WebAssembly will be the winner we’ve been waiting for, its adoption is wide enough, the core technology is stable enough that it’s worth considering it for even professional cases. So in this guide we’ll walk through setting up the tooling and development environment for building and using WebAssembly in Rust, embedding it in a TypeScript project, review how communication between TypeScript and Rust can happen, then finally how you can debug your WebAssembly directly in the browser and/or your favorite IDE.\",\"score\":0.4630806,\"raw_content\":null},{\"url\":\"https://rustwasm.github.io/book\",\"title\":\"Introduction - Rust and WebAssembly\",\"content\":\"This is **unpublished** documentation of working with Rust and WebAssembly, the published documentation is available on the main Rust and WebAssembly documentation site .

For now, the Rust team is focusing on the latter case, and so that's what we cover here. In this tutorial, we build a package using `wasm-pack`, a tool for building JavaScript packages in Rust. This package will contain only WebAssembly and JavaScript code, so users won't need Rust installed. They may not even notice that it's written in Rust. Install Rust by going to the Install Rust\\\") page and following the instructions. To build the package, we need an additional tool, `wasm-pack`.

It's a lot of complexity for a single niche use case (less overhead for string conversion - but passing tons of strings across the boundary is really only needed for one use case: when doing a 1:1 mapping of the DOM API). I really doubt that web APIs like WebGPU or WebGL would see similar performance improvements, and it's unclear how the much more critical performance problems for accessing WebGPU from WASM would be solved by the WASM Component Model (e.g. WebGPU maps WGPUBuffer content into separate JS ArrayBuffer objects which cannot be accessed directly from WASM without copying the data in and out of the WASM heap).\",\"score\":0.18621376,\"raw_content\":null},{\"url\":\"https://www.reddit.com/r/rust/comments/1hr6rvl/are_there_any_easily_embeddable_wasm_compilers\",\"title\":\"Are there any easily embeddable WASM compilers for Rust ... - Reddit\",\"content\":\"Are there any Rust crates that enable embedding a WASM compiler so that I can create a Rust application that also has the ability to compile some kind of\",\"score\":0.17711271,\"raw_content\":null},{\"url\":\"https://users.rust-lang.org/t/whats-everyone-working-on-this-week-1-2026/137368\",\"title\":\"What's everyone working on this week (1/2026)? - Rust Users Forum\",\"content\":\"This is the 5th week working on the same \\\"**blazingly fast**\\\" concurrent ordered map project and replying to this post :'D , and I have somehow managed to surpass the performance in MOST benchmarks against original C++ implementation, std's `RwLock` and other popular concurrent ordered map crates (`scc:TreeIndex, crossbeam-skiplist` etc) that are currently available O.O.

This tutorial shows you how to compile a Rust project into WebAssembly and use it in an existing web app. ## Rust and WebAssembly use cases. There are two main use cases for Rust and WebAssembly:. For now, the Rust team is focusing on the latter case, and so that's what we cover here. In this tutorial, we build a package using `wasm-pack`, a tool for building JavaScript packages in Rust. This package will contain only WebAssembly and JavaScript code, so users won't need Rust installed. They may not even notice that it's written in Rust. Install Rust by going to the Install Rust\") page and following the instructions. To build the package, we need an additional tool, `wasm-pack`.

It's a lot of complexity for a single niche use case (less overhead for string conversion - but passing tons of strings across the boundary is really only needed for one use case: when doing a 1:1 mapping of the DOM API). I really doubt that web APIs like WebGPU or WebGL would see similar performance improvements, and it's unclear how the much more critical performance problems for accessing WebGPU from WASM would be solved by the WASM Component Model (e.g. WebGPU maps WGPUBuffer content into separate JS ArrayBuffer objects which cannot be accessed directly from WASM without copying the data in and out of the WASM heap).","score":0.18621376,"raw_content":null},{"url":"https://www.reddit.com/r/rust/comments/1hr6rvl/are_there_any_easily_embeddable_wasm_compilers","title":"Are there any easily embeddable WASM compilers for Rust ... - Reddit","content":"Are there any Rust crates that enable embedding a WASM compiler so that I can create a Rust application that also has the ability to compile some kind of","score":0.17711271,"raw_content":null},{"url":"https://users.rust-lang.org/t/whats-everyone-working-on-this-week-1-2026/137368","title":"What's everyone working on this week (1/2026)? - Rust Users Forum","content":"This is the 5th week working on the same \"**blazingly fast**\" concurrent ordered map project and replying to this post :'D , and I have somehow managed to surpass the performance in MOST benchmarks against original C++ implementation, std's `RwLock` and other popular concurrent ordered map crates (`scc:TreeIndex, crossbeam-skiplist` etc) that are currently available O.O.

It’s clear WebAssembly is one of the more popular up-and-coming technologies out there. While it can run on most systems now, the web is still not one of them. Enter WebAssembly (or WASM for short), supported by a wide consortium of players, developed in the open and as an open standard, with the WEB as its primary platform. While it’s too early to tell if WebAssembly will be the winner we’ve been waiting for, its adoption is wide enough, the core technology is stable enough that it’s worth considering it for even professional cases. So in this guide we’ll walk through setting up the tooling and development environment for building and using WebAssembly in Rust, embedding it in a TypeScript project, review how communication between TypeScript and Rust can happen, then finally how you can debug your WebAssembly directly in the browser and/or your favorite IDE.\",\"score\":0.4630806,\"raw_content\":null},{\"url\":\"https://rustwasm.github.io/book\",\"title\":\"Introduction - Rust and WebAssembly\",\"content\":\"This is **unpublished** documentation of working with Rust and WebAssembly, the published documentation is available on the main Rust and WebAssembly documentation site .

It’s clear WebAssembly is one of the more popular up-and-coming technologies out there. While it can run on most systems now, the web is still not one of them. Enter WebAssembly (or WASM for short), supported by a wide consortium of players, developed in the open and as an open standard, with the WEB as its primary platform. While it’s too early to tell if WebAssembly will be the winner we’ve been waiting for, its adoption is wide enough, the core technology is stable enough that it’s worth considering it for even professional cases. So in this guide we’ll walk through setting up the tooling and development environment for building and using WebAssembly in Rust, embedding it in a TypeScript project, review how communication between TypeScript and Rust can happen, then finally how you can debug your WebAssembly directly in the browser and/or your favorite IDE.","score":0.4630806,"raw_content":null},{"url":"https://rustwasm.github.io/book","title":"Introduction - Rust and WebAssembly","content":"This is **unpublished** documentation of working with Rust and WebAssembly, the published documentation is available on the main Rust and WebAssembly documentation site .

For now, the Rust team is focusing on the latter case, and so that's what we cover here. In this tutorial, we build a package using `wasm-pack`, a tool for building JavaScript packages in Rust. This package will contain only WebAssembly and JavaScript code, so users won't need Rust installed. They may not even notice that it's written in Rust. Install Rust by going to the Install Rust\") page and following the instructions. To build the package, we need an additional tool, `wasm-pack`.

It's a lot of complexity for a single niche use case (less overhead for string conversion - but passing tons of strings across the boundary is really only needed for one use case: when doing a 1:1 mapping of the DOM API). I really doubt that web APIs like WebGPU or WebGL would see similar performance improvements, and it's unclear how the much more critical performance problems for accessing WebGPU from WASM would be solved by the WASM Component Model (e.g. WebGPU maps WGPUBuffer content into separate JS ArrayBuffer objects which cannot be accessed directly from WASM without copying the data in and out of the WASM heap).","score":0.18621376,"raw_content":null},{"url":"https://www.reddit.com/r/rust/comments/1hr6rvl/are_there_any_easily_embeddable_wasm_compilers","title":"Are there any easily embeddable WASM compilers for Rust ... - Reddit","content":"Are there any Rust crates that enable embedding a WASM compiler so that I can create a Rust application that also has the ability to compile some kind of","score":0.17711271,"raw_content":null},{"url":"https://users.rust-lang.org/t/whats-everyone-working-on-this-week-1-2026/137368","title":"What's everyone working on this week (1/2026)? - Rust Users Forum","content":"This is the 5th week working on the same \"**blazingly fast**\" concurrent ordered map project and replying to this post :'D , and I have somehow managed to surpass the performance in MOST benchmarks against original C++ implementation, std's `RwLock` and other popular concurrent ordered map crates (`scc:TreeIndex, crossbeam-skiplist` etc) that are currently available O.O.

It’s clear WebAssembly is one of the more popular up-and-coming technologies out there. While it can run on most systems now, the web is still not one of them. Enter WebAssembly (or WASM for short), supported by a wide consortium of players, developed in the open and as an open standard, with the WEB as its primary platform. While it’s too early to tell if WebAssembly will be the winner we’ve been waiting for, its adoption is wide enough, the core technology is stable enough that it’s worth considering it for even professional cases. So in this guide we’ll walk through setting up the tooling and development environment for building and using WebAssembly in Rust, embedding it in a TypeScript project, review how communication between TypeScript and Rust can happen, then finally how you can debug your WebAssembly directly in the browser and/or your favorite IDE.","score":0.4630806,"raw_content":null},{"url":"https://rustwasm.github.io/book","title":"Introduction - Rust and WebAssembly","content":"This is **unpublished** documentation of working with Rust and WebAssembly, the published documentation is available on the main Rust and WebAssembly documentation site .

For now, the Rust team is focusing on the latter case, and so that's what we cover here. In this tutorial, we build a package using `wasm-pack`, a tool for building JavaScript packages in Rust. This package will contain only WebAssembly and JavaScript code, so users won't need Rust installed. They may not even notice that it's written in Rust. Install Rust by going to the Install Rust\\\") page and following the instructions. To build the package, we need an additional tool, `wasm-pack`.

It's a lot of complexity for a single niche use case (less overhead for string conversion - but passing tons of strings across the boundary is really only needed for one use case: when doing a 1:1 mapping of the DOM API). I really doubt that web APIs like WebGPU or WebGL would see similar performance improvements, and it's unclear how the much more critical performance problems for accessing WebGPU from WASM would be solved by the WASM Component Model (e.g. WebGPU maps WGPUBuffer content into separate JS ArrayBuffer objects which cannot be accessed directly from WASM without copying the data in and out of the WASM heap).\",\"score\":0.18621376,\"raw_content\":null},{\"url\":\"https://www.reddit.com/r/rust/comments/1hr6rvl/are_there_any_easily_embeddable_wasm_compilers\",\"title\":\"Are there any easily embeddable WASM compilers for Rust ... - Reddit\",\"content\":\"Are there any Rust crates that enable embedding a WASM compiler so that I can create a Rust application that also has the ability to compile some kind of\",\"score\":0.17711271,\"raw_content\":null},{\"url\":\"https://users.rust-lang.org/t/whats-everyone-working-on-this-week-1-2026/137368\",\"title\":\"What's everyone working on this week (1/2026)? - Rust Users Forum\",\"content\":\"This is the 5th week working on the same \\\"**blazingly fast**\\\" concurrent ordered map project and replying to this post :'D , and I have somehow managed to surpass the performance in MOST benchmarks against original C++ implementation, std's `RwLock` and other popular concurrent ordered map crates (`scc:TreeIndex, crossbeam-skiplist` etc) that are currently available O.O.

It’s clear WebAssembly is one of the more popular up-and-coming technologies out there. While it can run on most systems now, the web is still not one of them. Enter WebAssembly (or WASM for short), supported by a wide consortium of players, developed in the open and as an open standard, with the WEB as its primary platform. While it’s too early to tell if WebAssembly will be the winner we’ve been waiting for, its adoption is wide enough, the core technology is stable enough that it’s worth considering it for even professional cases. So in this guide we’ll walk through setting up the tooling and development environment for building and using WebAssembly in Rust, embedding it in a TypeScript project, review how communication between TypeScript and Rust can happen, then finally how you can debug your WebAssembly directly in the browser and/or your favorite IDE.","score":0.4630806,"raw_content":null},{"url":"https://rustwasm.github.io/book","title":"Introduction - Rust and WebAssembly","content":"This is **unpublished** documentation of working with Rust and WebAssembly, the published documentation is available on the main Rust and WebAssembly documentation site .

This package will contain only WebAssembly and JavaScript code, so users won't need Rust installed. They may not even notice that it's written in Rust. Install Rust by going to the Install Rust\\\") page and following the instructions. To build the package, we need an additional tool, `wasm-pack`.

It's a lot of complexity for a single niche use case (less overhead for string conversion - but passing tons of strings across the boundary is really only needed for one use case: when doing a 1:1 mapping of the DOM API). I really doubt that web APIs like WebGPU or WebGL would see similar performance improvements, and it's unclear how the much more critical performance problems for accessing WebGPU from WASM would be solved by the WASM Component Model (e.g. WebGPU maps WGPUBuffer content into separate JS ArrayBuffer objects which cannot be accessed directly from WASM without copying the data in and out of the WASM heap).\",\"score\":0.18621376,\"raw_content\":null},{\"url\":\"https://www.reddit.com/r/rust/comments/1hr6rvl/are_there_any_easily_embeddable_wasm_compilers\",\"title\":\"Are there any easily embeddable WASM compilers for Rust ... - Reddit\",\"content\":\"Are there any Rust crates that enable embedding a WASM compiler so that I can create a Rust application that also has the ability to compile some kind of\",\"score\":0.17711271,\"raw_content\":null},{\"url\":\"https://users.rust-lang.org/t/whats-everyone-working-on-this-week-1-2026/137368\",\"title\":\"What's everyone working on this week (1/2026)? - Rust Users Forum\",\"content\":\"This is the 5th week working on the same \\\"**blazingly fast**\\\" concurrent ordered map project and replying to this post :'D , and I have somehow managed to surpass the performance in MOST benchmarks against original C++ implementation, std's `RwLock` and other popular concurrent ordered map crates (`scc:TreeIndex, crossbeam-skiplist` etc) that are currently available O.O.

For now, the Rust team is focusing on the latter case, and so that's what we cover here. In this tutorial, we build a package using `wasm-pack`, a tool for building JavaScript packages in Rust. This package will contain only WebAssembly and JavaScript code, so users won't need Rust installed. They may not even notice that it's written in Rust. Install Rust by going to the Install Rust\\\") page and following the instructions. To build the package, we need an additional tool, `wasm-pack`.

It's a lot of complexity for a single niche use case (less overhead for string conversion - but passing tons of strings across the boundary is really only needed for one use case: when doing a 1:1 mapping of the DOM API). I really doubt that web APIs like WebGPU or WebGL would see similar performance improvements, and it's unclear how the much more critical performance problems for accessing WebGPU from WASM would be solved by the WASM Component Model (e.g. WebGPU maps WGPUBuffer content into separate JS ArrayBuffer objects which cannot be accessed directly from WASM without copying the data in and out of the WASM heap).\",\"score\":0.18621376,\"raw_content\":null},{\"url\":\"https://www.reddit.com/r/rust/comments/1hr6rvl/are_there_any_easily_embeddable_wasm_compilers\",\"title\":\"Are there any easily embeddable WASM compilers for Rust ... - Reddit\",\"content\":\"Are there any Rust crates that enable embedding a WASM compiler so that I can create a Rust application that also has the ability to compile some kind of\",\"score\":0.17711271,\"raw_content\":null},{\"url\":\"https://users.rust-lang.org/t/whats-everyone-working-on-this-week-1-2026/137368\",\"title\":\"What's everyone working on this week (1/2026)? - Rust Users Forum\",\"content\":\"This is the 5th week working on the same \\\"**blazingly fast**\\\" concurrent ordered map project and replying to this post :'D , and I have somehow managed to surpass the performance in MOST benchmarks against original C++ implementation, std's `RwLock` and other popular concurrent ordered map crates (`scc:TreeIndex, crossbeam-skiplist` etc) that are currently available O.O.

A project using Rust, WASM, React & JS. Contribute to helabenkhalfallah/rust-react-wasm-js development by creating an account on GitHub. What I want to do is to delegate some heavy tasks to Rust and WASM. In my POC project I tried a first basic thing : filter an array using native JS and filter using Rust+WASM (js call Rust function).

The WebAssembly ecosystem, particularly when paired with Rust, has been a whirlwind of activity in 2024 and 2025. As a developer who's been hands-on with these advancements, I can tell you that the progress isn't just incremental; it's fundamentally shifting what's possible in browser-based applications and beyond.

As a member of the Rust Infrastructure team, I do many small and drive-by contributions to various repositories to fix CI, update configs or docs, set up some tooling, etc.","score":0.052293845,"raw_content":null}],"response_time":0.73,"request_id":"9cff4506-7b40-4bcf-9497-6a4910575443"},"isError":false},"server":"tavily","tool":"tavily_search"},"isError":false,"timestamp":1781111236701}} {"type":"message","id":"29c9edcc","parentId":"2445535b","timestamp":"2026-06-10T17:07:21.349Z","message":{"role":"assistant","content":[{"type":"thinking","thinking":"搜索结果中提到了一个 Medium 文章：\"Designing a Real Rust-to-MIR Browser Runtime Today — A Playable Prototype\"。这看起来是一个 Rust 浏览器运行时的项目。让我看看这个文章。\n\n另外，我已经搜索了很多，但没有找到现成的、体积小的 Rust 浏览器编译器。让我再尝试一次搜索，看看这个 Medium 文章提到的项目。","thinkingSignature":"reasoning_content"},{"type":"toolCall","id":"functions.mcp:244","name":"mcp","arguments":{"server":"tavily","tool":"tavily_tavily_extract","args":"{\"urls\":[\"https://medium.com/@bugsybits/designing-a-real-rust-to-mir-browser-runtime-today-a-playable-prototype-b3938cd06556\"],\"include_images\":false}"}}],"api":"openai-completions","provider":"opencode-go-openai","model":"kimi-k2.6","usage":{"input":2525,"output":149,"cacheRead":180098,"cacheWrite":0,"totalTokens":182772,"cost":{"input":0.00239875,"output":0.000596,"cacheRead":0.02881568,"cacheWrite":0,"total":0.03181043}},"stopReason":"toolUse","timestamp":1781111236706,"responseId":"chatcmpl-e4913520f01442d19fa96eeb023d6984","responseModel":"accounts/fireworks/models/kimi-k2p6"}} {"type":"message","id":"5d52ed68","parentId":"29c9edcc","timestamp":"2026-06-10T17:07:23.486Z","message":{"role":"toolResult","toolCallId":"functions.mcp:244","toolName":"mcp","content":[{"type":"text","text":"{\"results\":[],\"failed_results\":[{\"url\":\"https://medium.com/@bugsybits/designing-a-real-rust-to-mir-browser-runtime-today-a-playable-prototype-b3938cd06556\",\"error\":\"Failed to fetch url\"}],\"response_time\":0.27,\"request_id\":\"29eee7b1-d46a-4c8f-9b7d-298c61a1119a\"}"}],"details":{"mode":"call","mcpResult":{"content":[{"type":"text","text":"{\"results\":[],\"failed_results\":[{\"url\":\"https://medium.com/@bugsybits/designing-a-real-rust-to-mir-browser-runtime-today-a-playable-prototype-b3938cd06556\",\"error\":\"Failed to fetch url\"}],\"response_time\":0.27,\"request_id\":\"29eee7b1-d46a-4c8f-9b7d-298c61a1119a\"}"}],"structuredContent":{"results":[],"failed_results":[{"url":"https://medium.com/@bugsybits/designing-a-real-rust-to-mir-browser-runtime-today-a-playable-prototype-b3938cd06556","error":"Failed to fetch url"}],"response_time":0.27,"request_id":"29eee7b1-d46a-4c8f-9b7d-298c61a1119a"},"isError":false},"server":"tavily","tool":"tavily_extract"},"isError":false,"timestamp":1781111243485}} {"type":"message","id":"73b2b7f2","parentId":"5d52ed68","timestamp":"2026-06-10T17:07:27.437Z","message":{"role":"assistant","content":[{"type":"thinking","thinking":"Medium 文章无法获取。让我搜索一下这个项目的 GitHub 链接。\n\n我已经搜索了很多，但没有找到现成的、体积小的 Rust 浏览器编译器。让我再尝试一次搜索，看看这个项目。","thinkingSignature":"reasoning_content"},{"type":"toolCall","id":"functions.mcp:245","name":"mcp","arguments":{"server":"tavily","tool":"tavily_tavily_search","args":"{\"query\":\"bugsybits rust mir browser runtime prototype github wasm\",\"max_results\":10}"}}],"api":"openai-completions","provider":"opencode-go-openai","model":"kimi-k2.6","usage":{"input":253,"output":92,"cacheRead":182622,"cacheWrite":0,"totalTokens":182967,"cost":{"input":0.00024035,"output":0.000368,"cacheRead":0.029219520000000002,"cacheWrite":0,"total":0.029827870000000003}},"stopReason":"toolUse","timestamp":1781111243491,"responseId":"chatcmpl-93d43ce0139c459c932d1a50645bdf2e","responseModel":"accounts/fireworks/models/kimi-k2p6"}} {"type":"message","id":"434a516e","parentId":"73b2b7f2","timestamp":"2026-06-10T17:07:29.517Z","message":{"role":"toolResult","toolCallId":"functions.mcp:245","toolName":"mcp","content":[{"type":"text","text":"{\"query\":\"bugsybits rust mir browser runtime prototype github wasm\",\"follow_up_questions\":null,\"answer\":null,\"images\":[],\"results\":[{\"url\":\"https://medium.com/@bugsybits/designing-a-real-rust-to-mir-browser-runtime-today-a-playable-prototype-b3938cd06556\",\"title\":\"Designing a Real Rust-to-MIR Browser Runtime Today - Medium\",\"content\":\"Designing a Real Rust-to-MIR Browser Runtime Today — A Playable Prototype How a Tiny MIR Interpreter, a Fake DOM, and a Dream Could Redefine\",\"score\":0.6083387,\"raw_content\":null},{\"url\":\"https://github.com/rust-lang/miri/issues/722\",\"title\":\"Compilation to WASM? · Issue #722 · rust-lang/miri - GitHub\",\"content\":\"## Navigation Menu. # Provide feedback.

It’s clear WebAssembly is one of the more popular up-and-coming technologies out there. While it can run on most systems now, the web is still not one of them. Enter WebAssembly (or WASM for short), supported by a wide consortium of players, developed in the open and as an open standard, with the WEB as its primary platform. While it’s too early to tell if WebAssembly will be the winner we’ve been waiting for, its adoption is wide enough, the core technology is stable enough that it’s worth considering it for even professional cases. So in this guide we’ll walk through setting up the tooling and development environment for building and using WebAssembly in Rust, embedding it in a TypeScript project, review how communication between TypeScript and Rust can happen, then finally how you can debug your WebAssembly directly in the browser and/or your favorite IDE.","score":0.4630806,"raw_content":null},{"url":"https://rustwasm.github.io/book","title":"Introduction - Rust and WebAssembly","content":"This is **unpublished** documentation of working with Rust and WebAssembly, the published documentation is available on the main Rust and WebAssembly documentation site .

Install Rust by going to the Install Rust\") page and following the instructions. To build the package, we need an additional tool, `wasm-pack`.

It's a lot of complexity for a single niche use case (less overhead for string conversion - but passing tons of strings across the boundary is really only needed for one use case: when doing a 1:1 mapping of the DOM API). I really doubt that web APIs like WebGPU or WebGL would see similar performance improvements, and it's unclear how the much more critical performance problems for accessing WebGPU from WASM would be solved by the WASM Component Model (e.g. WebGPU maps WGPUBuffer content into separate JS ArrayBuffer objects which cannot be accessed directly from WASM without copying the data in and out of the WASM heap).","score":0.18621376,"raw_content":null},{"url":"https://www.reddit.com/r/rust/comments/1hr6rvl/are_there_any_easily_embeddable_wasm_compilers","title":"Are there any easily embeddable WASM compilers for Rust ... - Reddit","content":"Are there any Rust crates that enable embedding a WASM compiler so that I can create a Rust application that also has the ability to compile some kind of","score":0.17711271,"raw_content":null},{"url":"https://users.rust-lang.org/t/whats-everyone-working-on-this-week-1-2026/137368","title":"What's everyone working on this week (1/2026)? - Rust Users Forum","content":"This is the 5th week working on the same \"**blazingly fast**\" concurrent ordered map project and replying to this post :'D , and I have somehow managed to surpass the performance in MOST benchmarks against original C++ implementation, std's `RwLock` and other popular concurrent ordered map crates (`scc:TreeIndex, crossbeam-skiplist` etc) that are currently available O.O.

To build the file for the WASM app, we’ll use wasm-pack, a tool covering from building Rust to generating a package to be published to `npm`, though We won’t publish our package in this post. ## wasm-pack and webpack#. Before pushing it, make sure to execute `npm run build` to generate files (.html, .js, and .wasm) in `www/dist` that should be deployed to GitHub.

It’s clear WebAssembly is one of the more popular up-and-coming technologies out there. While it can run on most systems now, the web is still not one of them. Enter WebAssembly (or WASM for short), supported by a wide consortium of players, developed in the open and as an open standard, with the WEB as its primary platform. While it’s too early to tell if WebAssembly will be the winner we’ve been waiting for, its adoption is wide enough, the core technology is stable enough that it’s worth considering it for even professional cases. So in this guide we’ll walk through setting up the tooling and development environment for building and using WebAssembly in Rust, embedding it in a TypeScript project, review how communication between TypeScript and Rust can happen, then finally how you can debug your WebAssembly directly in the browser and/or your favorite IDE.","score":0.51530343,"raw_content":null},{"url":"https://www.youtube.com/watch?v=P4LMfkFLRsI","title":"Rust & Wasm - YouTube","content":"...

To set up our project, we'll get started with using `cargo init --lib wasm-example` to create a new library project named `wasm-example`.

Enter WebAssembly (or WASM for short), supported by a wide consortium of players, developed in the open and as an open standard, with the WEB as its primary platform. While it’s too early to tell if WebAssembly will be the winner we’ve been waiting for, its adoption is wide enough, the core technology is stable enough that it’s worth considering it for even professional cases.

In this post, I described the custom Garbage Collector, and the parts of the core libraries I’d ported to Wasm. The Elm runtime remains in JavaScript because WebAssembly doesn’t have Web APIs yet. The Wasm app talks to the runtime through a JS wrapper. It was “hand compiled” as I didn’t have a working compiler yet. A lot of the work I’m currently doing is on the JS/Wasm interface. Since I have the runtime in JS and the app in Wasm, the interface between the two is a major focus.","score":0.280888,"raw_content":null},{"url":"https://blog.scottlogic.com/2019/05/17/webassembly-compiler.html","title":"Build your own WebAssembly Compiler - Scott Logic Blog","content":"I’ve always wanted to have a go at writing a compiler, and with the recent release of WebAssembly, I had the perfect excuse to have a go. My original plan was to *invent* my own programming language, create a compiler that targets WebAssembly, and share my experiences at FullStackNYC. So, rather than waste all that work - I thought I’d write up my talk as a blog post instead - hence the ‘19 min’ reading time for this article. You’ll learn the ‘what’ of WebAssembly throughout this blog post, but I do want to briefly touch on the ‘why’. Writing a compiler is a really good opportunity to delve into the details of WebAssembly to find it what it is and how it works. This language is compiled to WebAssembly using my compiler, which is written in TypeScript and runs in the browser. Here is an emitter (the term used for the part of a compiler that outputs instructions for the target system), that creates the smallest valid WebAssembly module:.","score":0.23670186,"raw_content":null},{"url":"https://www.reddit.com/r/javascript/comments/1lopzol/i_built_a_toy_compiler_in_typescript_for_pinky","title":"I built a toy compiler in TypeScript for Pinky that targets WebAssembly : r/javascript","content":"# I built a toy compiler in TypeScript for Pinky that targets WebAssembly : r/javascript.

Enter WebAssembly (or WASM for short), supported by a wide consortium of players, developed in the open and as an open standard, with the WEB as its primary platform. While it’s too early to tell if WebAssembly will be the winner we’ve been waiting for, its adoption is wide enough, the core technology is stable enough that it’s worth considering it for even professional cases. So in this guide we’ll walk through setting up the tooling and development environment for building and using WebAssembly in Rust, embedding it in a TypeScript project, review how communication between TypeScript and Rust can happen, then finally how you can debug your WebAssembly directly in the browser and/or your favorite IDE.","score":0.3197694,"raw_content":null}],"response_time":0.61,"request_id":"87d2ed54-719f-4085-babb-a13ea0127a96"},"isError":false},"server":"tavily","tool":"tavily_search"},"isError":false,"timestamp":1781111743115}} {"type":"message","id":"fcd9f521","parentId":"1fb71650","timestamp":"2026-06-10T17:15:43.116Z","message":{"role":"user","content":[{"type":"text","text":"- **wasm-pack 模板** + Yew/Leptos：构建 Rust WASM 静态网页的标准方式（GitHub Pages 友好）。很多示例项目可直接改成编译器前端。"}],"timestamp":1781111694317}} {"type":"message","id":"c997a5cf","parentId":"fcd9f521","timestamp":"2026-06-10T17:15:45.865Z","message":{"role":"assistant","content":[{"type":"thinking","thinking":"用户确认了 wasm-pack 模板 + Yew/Leptos 是构建 Rust WASM 静态网页的标准方式。让我继续搜索更多具体的示例项目，特别是编译器/解释器相关的。","thinkingSignature":"reasoning_content"},{"type":"toolCall","id":"functions.mcp:272","name":"mcp","arguments":{"server":"tavily","tool":"tavily_tavily_search","args":"{\"query\":\"yew leptos wasm compiler interpreter playground github rust\",\"max_results\":10}"}}],"api":"openai-completions","provider":"opencode-go-openai","model":"kimi-k2.6","usage":{"input":2744,"output":91,"cacheRead":76535,"cacheWrite":0,"totalTokens":79370,"cost":{"input":0.0026068,"output":0.00036399999999999996,"cacheRead":0.0122456,"cacheWrite":0,"total":0.015216400000000001}},"stopReason":"toolUse","timestamp":1781111743119,"responseId":"chatcmpl-1941b6b9a91e4e2c9a72f66bf512000b","responseModel":"accounts/fireworks/models/kimi-k2p6"}} {"type":"message","id":"1d317999","parentId":"c997a5cf","timestamp":"2026-06-10T17:15:46.954Z","message":{"role":"toolResult","toolCallId":"functions.mcp:272","toolName":"mcp","content":[{"type":"text","text":"{\"query\":\"yew leptos wasm compiler interpreter playground github rust\",\"follow_up_questions\":null,\"answer\":null,\"images\":[],\"results\":[{\"url\":\"https://github.com/leptos-rs/leptos\",\"title\":\"GitHub - leptos-rs/leptos: Build fast web applications with Rust.\",\"content\":\"Yew is the most-used library for Rust web UI development, but there are several differences between Yew and Leptos, in philosophy, approach, and performance.\",\"score\":0.6780931,\"raw_content\":null},{\"url\":\"https://dev.to/godofgeeks/rust-for-webassembly-yewleptos-4mjc\",\"title\":\"Rust for WebAssembly (Yew/Leptos) - DEV Community\",\"content\":\"# Rust for WebAssembly (Yew/Leptos). ## Rust Meets the Web: Unleashing the Power of WebAssembly with Yew & Leptos.

\n    \n    \n\n\n```\n\n#### 第五步：部署\n```bash\n# 所有文件（index.html + pkg/）即为静态站点\n# 可用 nginx 或 GitHub Pages 部署\n```\n\n### 3. 进阶方案：直接编译到 WASM 在浏览器运行\n\n如果你想要的是**在浏览器里编译 Rust 子集代码**（类似我们已有的 Python/Go/C 编译器），思路类似：\n\n1. **用 Rust 写一个简单语言的解释器**（如 Brainfuck/Lisp 子集）\n2. **编译这个解释器本身为 WASM**（不是编译目标语言为 WASM）\n3. **前端把用户代码传给 WASM 解释器执行**\n\n示例架构：\n```\n用户代码 → JS 前端 → WASM 解释器（Rust 写）→ 执行结果 → 输出到页面\n```\n\n这与我们现有的 **Go-WASM 编译器**（yaegi 解释器编译到 WASM）架构完全一致。\n\n### 4. 具体 Rust 项目参考\n\n| 项目 | 可直接用 |\n|------|---------|\n| **[pretzelhammer/brainfuck_compilers](https://github.com/pretzelhammer/brainfuck_compilers)** | ✅ 最推荐，已有 WASM 目标 |\n| **[GrzegorzKazana/toy-interpreter](https://github.com/GrzegorzKazana/toy-interpreter)** | ✅ Rust 写，已有 WASM + Sapper 前端 |\n| **[explodingcamera/tinywasm](https://github.com/explodingcamera/tinywasm)** | ✅ Rust 写的 WASM 运行时，可嵌入 |\n\n---\n\n## 总结\n\n最快路径：**pretzelhammer/brainfuck_compilers** + **wasm-pack** + **静态 HTML** = 一个完整的 Rust+WASM 迷你编译器网页。\n\n如果你需要我帮你实际搭建一个（基于某个具体项目），告诉我选择哪个基础项目，我可以帮你配置 wasm-pack 编译和前端页面。"}],"api":"openai-completions","provider":"opencode-go-openai","model":"kimi-k2.6","usage":{"input":1641,"output":1360,"cacheRead":79278,"cacheWrite":0,"totalTokens":82279,"cost":{"input":0.00155895,"output":0.0054399999999999995,"cacheRead":0.01268448,"cacheWrite":0,"total":0.01968343}},"stopReason":"stop","timestamp":1781111746958,"responseId":"chatcmpl-420fabb09864465e86a5cc6c233b2f5a","responseModel":"accounts/fireworks/models/kimi-k2p6"}}
