`karma-remap-coverage` is a Karma reporter plugin that displays code coverage for the original, non-transpiled source code (such as TypeScript or ES6/7) rather than the transpiled output. It's designed for developers using transpilers like TypeScript or Babel who want to see accurate coverage metrics for their original source files, particularly useful in projects that rely on source maps for debugging. The tool works seamlessly with `karma-coverage` and `remap-istanbul`, requires no temporary files, and supports watch mode for real-time coverage reporting.
