ts-eager is a fast TypeScript runner that uses esbuild for eager compilation of files specified in your tsconfig.json, making it ideal for tasks like running tests where many files need to be loaded quickly. It falls back to ts-node for unsupported features like emitDecoratorMetadata and can optionally integrate with tsconfig-paths for path resolution. This tool is perfect for developers seeking a performance boost over ts-node in scenarios where eager compilation is beneficial.
