vite-plugin-tsc-watch

Plugs tsc --watch into Vite dev server, enabling TypeScript type-checking during development without blocking the build pipeline. Current stable version is 3.1.2 (Feb 2025), with releases roughly every 6 months tracking Vite and TypeScript peer updates. Key differentiators: dev-only, low-noise (no overlay), uses Vite's dev server for logging, lightweight compared to alternatives like fork-ts-checker-webpack-plugin. Supports TS solution config and ESM-only since v3.
