karma-vite

A Karma plugin that uses Vite to transform ES modules for testing. Current stable version is 1.0.5, released December 2023, supporting Vite 2 through 5. It enables using Vite's fast development server and module transformation within Karma test runner. Unlike karma-webpack or karma-rollup, it leverages Vite's on-demand compilation and HMR-like middleware for quicker test re-runs. Requires Karma 6+ and Vite 2-5 as peer dependencies. Ships TypeScript types.
