A set of npm modules implementing the Language Server Protocol (LSP) in TypeScript for Node.js, including client, server, protocol definition, and JSON-RPC messaging libraries. It enables building language services (completion, diagnostics, hover, etc.) that work with VSCode and other LSP-capable editors.

Use cases

• implement a language server for a custom programming language
• build a VSCode extension that provides IntelliSense features
• add diagnostics and linting to an editor via LSP
• connect a VSCode extension to a language server over JSON-RPC
• implement text document syncing in an LSP server
• build editor tooling for a DSL in TypeScript

When to choose

• you are writing a language server or LSP client in JavaScript or TypeScript
• you want official, well-maintained LSP bindings for Node.js
• you are building a VSCode extension that provides language features

When to avoid

• you need LSP support in a language other than JS/TS (use a native LSP library instead)
• you are building a non-language-related VSCode extension
• you need a standalone editor rather than editor integration
