怎么用

商店整理自技能原文 · 版本 6481063 · 表述以原文为准

它做什么

装上后，Claude 会通过全局 MCP 服务器（端口 6060）管理 WebAssembly 项目，自动使用 tinywasm/fmt、tinywasm/time、tinywasm/json 等兼容库编写前端 Go 代码，并避免在 WASM 代码中使用 map 以减少二进制体积。

什么时候触发

当你在开发 WebAssembly 前端项目，或需要处理 tinywasm MCP 服务器相关任务时触发。

装好后可以这样说

Claude 会使用 tinywasm/fmt 替代标准库。

Claude 会移除 map 声明。

WebAssembly

WebAssembly Environment (tinywasm):
Global MCP Server: The LLM interacts with projects exclusively via the global MCP server on port 6060. If it is not running, the LLM must start it using the tinywasm -mcp command.
Starting Development: Use the start_development MCP tool to run the project compiler and file watcher in the background (headless mode). Do NOT run tinywasm directly in a shell yourself to start a project.
TUI Client (Human): The human developer attaches to live logs by running tinywasm in their terminal (acting as a view-only SSE client). If they press Ctrl+C, the TUI closes but the project continues compiling/running in the background for you. To fully stop the active project, they press q.
Frontend Go Compatibility: Use standard library replacements for tinygo compatibility. Use tinywasm/fmt instead of fmt/strings/strconv/errors; tinywasm/time instead of time; and tinywasm/json instead of encoding/json.
Frontend Optimization: Avoid using map declarations in WASM code to prevent binary bloat. Use structs or slices for small collections instead.
Goroutines and Channels: TinyGo's WASM target (targets/wasm.json) uses "scheduler": "asyncify" by default. Channels and blocking channel operations (<-ch) are fully compatible — asyncify pauses the WASM goroutine, lets the JS event loop run, and resumes when the channel receives a value. The goroutine+channel pattern for JS async bridges (js.FuncOf callbacks sending into a channel) is safe and proven in tinywasm/indexdb.
