プロジェクトの歴史

The public repository was created on 2022-11-20, and the npm package `@vtsls/language-server` was first published on 2022-12-12. The README emphasizes a maintenance strategy: fill enough VS Code APIs and apply only small patches so the wrapper can track upstream VS Code TypeScript extension changes.

採用の歴史

vtsls found its niche in editor communities that wanted richer TypeScript and JavaScript behavior than older generic tsserver LSP adapters provided. Its README lists Neovim integration through nvim-lspconfig and nvim-vtsls, and Vue language tooling later referenced vtsls as part of the non-VS Code editor story for Vue 3 language-server integration.

使われ方

Typical use is to install `@vtsls/language-server` and launch `vtsls --stdio` from an LSP client. Users can rely on the bundled TypeScript version, switch to the workspace TypeScript version, tune tsserver memory for large projects, and expose VS Code-like TypeScript commands such as organize imports, reload projects, source definitions, and tsserver requests.

パッケージ好きにとっての重要性

vtsls matters because it packages the VS Code TypeScript extension model for editors that speak LSP. It sits in the space between `typescript-language-server`, coc-tsserver, editor-specific plugins, and framework language servers such as Vue's, so package users care less about a standalone CLI UX and more about whether their editor can launch the binary and coordinate TypeScript plugins correctly.
