MCP Server for Zig Standard Library Documentation

A Model Context Protocol (MCP) server, zig-mcp, provides up-to-date documentation for the Zig programming language standard library and built-in functions. It reads standard library source files directly (similar to ziglang.org's official autodoc), but outputs Markdown instead of HTML, reducing token usage. Supports Node.js and Bun, and offers a command-line interface for version control and update management, including manual, daily, and startup update policies.

tsbro: TypeScript in the Browser, No Build Steps Needed

tsbro is a new library that simplifies using TypeScript in the browser. It bypasses the browser's import system, using synchronous XHR to fetch TypeScript code, transpiling it to JavaScript with swc wasm, and converting it to CJS for synchronous require. This allows developers to run TypeScript code directly in the browser without build steps, and use external libraries like Preact, ideal for quick prototyping or PoCs. Current limitations include difficult-to-read stack traces and the need for manual ambient declaration files.
