TypeScript

Language server: vtsls (preferred)

Setup

Krait auto-installs vtsls on first use via npm. To pre-install:

npm install -g @vtsls/language-server

Requirements

• tsconfig.json at the project root (or workspace root in a monorepo)
• Node.js in PATH

Monorepos

Each sub-package with a tsconfig.json is detected as a separate workspace. Run krait init to generate the workspace config:

krait init

Supported Operations

All krait operations work with TypeScript:

• find symbol — resolves types, interfaces, functions, classes
• hover — shows full type signatures and JSDoc
• check — TypeScript compiler errors and warnings
• edit replace — replaces symbol body with LSP-aware boundaries
• rename — cross-file rename with TypeScript compiler

Troubleshooting

Symbols not found: Ensure tsconfig.json exists. Missing tsconfig causes degraded resolution.

Slow first query: vtsls needs 2-10s to load all types on first start. Subsequent queries are 20-60ms.

Monorepo packages missing: Run krait init to detect and register all packages.
