See this for installing vtsls the TypeScript LSP plugin for Claude Code.
npm install -g typescript-language-server typescript
npm install -g @vtsls/language-server typescript
$env:ENABLE_LSP_TOOL=1
claude
In Claude Code:
/plugin marketplace add anthropics/claude-code
/plugin marketplace add boostvolt/claude-code-lsps
/plugin install vtsls@claude-code-lsps
Then restart with new CLI window and start Claude Code again. And you will see an error since you are on Windows:
LSP for vtsls failed ยท /plugin for details
That’s because of this. Basically just edit .lsp.json file like this:
And restart Claude Code, and it will be working.
There are two .lsp.json files that may require editing:
C:\Users\your_user\.claude\plugins\marketplaces\claude-code-lsps\vtsls\.lsp.json
C:\Users\your_user\.claude\plugins\cache\claude-code-lsps\vtsls\1.0.0\.lsp.json
