TypeScript LSP

Adds TypeScript and JavaScript language intelligence to Claude Code: type-aware completions, go-to-definition, find-references, hover types, signature help, and real-time diagnostics. It reads your project's tsconfig, follows project references in monorepos, pulls type declarations from node_modules, and watches files so completion and errors reflect your workspace and compiler options.

Provides refactor actions and quick fixes you can run inline: rename symbol across files, apply auto-import suggestions, organize imports, and run code actions that fix common type issues. Completions include semantic suggestions and auto-imports; hover shows inferred types and JSDoc. Diagnostics come from the TypeScript checker and include suggested edits you can apply with one click.

The LSP integration answers go-to-definition and find-references requests, lists workspace symbols, maps references to exact ranges, and updates as you type. It supports JSX/TSX, resolves path aliases and module specifiers, and exposes signature help and code lenses where appropriate so you can operate without jumping to another tool.

When you’re reviewing a PR or refactoring a shared utility in a monorepo, rename a function across packages, see where a type change breaks callers, and accept quick fixes without opening VS Code or running tsc in a terminal. That saves context switches and gets small edits merged faster.
