claude-code-lsp-bridge

TypeScript 7 code intelligence for Claude Code: navigation and post-edit diagnostics. Fixes provides no tsserver.js with TypeScript 7 in Claude Code.

Why

• The official typescript-lsp plugin wraps tsserver.js, which TypeScript 7 removed.
• TypeScript 7's own server, tsc --lsp, reports per-file errors only on request (pull). Claude Code only listens for errors the server sends on its own (push).

Bridge

bridge.mjs forwards all LSP traffic unchanged. After each file open, change or save, it requests that file's errors from the server and sends them to Claude Code as push.
