karma-webpack

Karma plugin that uses webpack to preprocess test files. Current stable version is 5.0.1, released February 2024, with a release cadence of roughly major versions every 1-2 years. It provides both a Karma framework and preprocessor, bundling test files and dependencies into shared bundles and chunks via webpack 5. Key differentiators: seamless integration of webpack with Karma's test runner, automatic handling of multiple outputs, and support for TypeScript out of the box. Requires webpack ^5.0.0 as a peer dependency and Node >=18.
