chore(devenv): add typescript-language-server - #1180
Merged
Conversation
Puts the LSP adapter for tsserver on PATH so LSP-based tools (Claude Code LSP, neovim, helix) get TypeScript code intelligence. The adapter uses the workspace's own typescript from node_modules for analysis, so the analysis version stays pinned by package.json. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

What
Adds
pkgs.typescript-language-serverto the devenv packages list.Why
LSP-based tools (Claude Code's LSP tool, neovim, helix) need an LSP front end for TypeScript. The
typescriptnpm dep ships onlytscandtsserver;tsserverspeaks its own private protocol, not LSP. This adapter accepts LSP and forwards to the workspace's owntsserver, so the TypeScript version that does the analysis stays pinned bypackage.json. VS Code users are unaffected (VS Code talks to tsserver directly).Verification
nix evalagainst the locked nixpkgs input (8d029aa6) resolves the attribute (v5.1.3).nix run <pinned>#typescript-language-server -- --versionfetches and runs:5.1.3.After merge:
direnv reload(or re-enter the repo dir) picks it up.🤖 Generated with Claude Code
