Karma TypeScript Preprocessor

This package, `karma-typescript-preprocessor`, provides a Karma runner plugin designed to compile TypeScript files on the fly during unit testing. It integrates directly into the Karma configuration, allowing developers to test TypeScript code without a separate, explicit compilation step prior to running tests. The package is currently at version 0.4.0, with its last update occurring approximately seven years ago. Given its age, it is no longer actively maintained and may not support recent TypeScript versions or Karma features. While it offered configurable TypeScript compiler options like `target`, `module`, and `sourceMap` directly within `karma.conf.js`, its primary differentiator was simplifying test setups by handling TypeScript compilation internally, contrasting with the more feature-rich and actively maintained `karma-typescript` package which offers bundling, coverage remapping, and broader framework support.
