Test your LLM-powered apps with a TypeScript-native, Vitest-based eval runner. No API key required.
Evalite is still an experimental project. I'm actively working on it, and for now am pushing breaking changes.
If you run into any unexpected behavior:
node_modules/.evalite folder.evalite to the latest version.If, after that, you run into unexpected behavior, report an issue.
You can run Evalite in watch mode by running evalite watch:
evalite watch
This will watch for changes to your .eval.ts files and re-run the evals when they change.
[!IMPORTANT]
I strongly recommend implementing a caching layer in your LLM calls when using watch mode. This will keep your evals running fast and avoid burning through your API credits.
You can run specific files by passing them as arguments:
evalite my-eval.eval.ts
This also works for watch mode:
evalite watch my-eval.eval.ts
