Show HN: TypeScript7 LSP Claude Code Plugin

A developer released an unofficial community plugin for Claude Code that replaces the official TypeScript LSP with a faster native Go implementation backed by TypeScript 7's `tsc --lsp --stdio`. The plugin, available on GitHub under a public-domain license, aims to improve performance by using the native TypeScript 7 server instead of the Node-based wrapper.

A Claude Code https://claude.com/claude-code marketplace that provides a TypeScript language server backed by the native TypeScript 7 server typescript@rc , launched as tsc --lsp --stdio . It replaces the official typescript-lsp plugin which uses the Node-based typescript-language-server wrapper around the classic tsserver with the faster native Go implementation. Unofficial.This is a community project and isnotaffiliated with, endorsed by, or maintained by Microsoft or the TypeScript team. "TypeScript" and tsc are products of Microsoft; this repo just wires the typescript@rc LSP into Claude Code.
