TypeScript Language Server

The TypeScript Language Server provides a Language Server Protocol (LSP) implementation for TypeScript and JavaScript projects, acting as a bridge between editors and Microsoft's `tsserver` component. It allows any LSP-compliant editor to leverage the rich code intelligence features originally developed for VSCode, which internally uses `tsserver` via a non-standard API. This project wraps that functionality in a standard LSP interface, making it accessible to a wider ecosystem of editors. The current stable version is 5.1.3, released in November 2025, with a consistent cadence of patch and minor updates following its major v5.0.0 release in September 2025. Key differentiators include its role in standardizing `tsserver` access via LSP and its community-maintained status, separate from Microsoft's official tooling. Developers should note that while it uses `tsserver`, it is not the same as the built-in TypeScript features extension in VSCode, and a future, Go-based TypeScript 7 from Microsoft may eventually offer a native LSP implementation that could supersede this project.
