What's New

We’ve re-imagined Wallaby.js to deliver more power, flexibility, and a seamless experience across all editors. Wallaby v2 introduces an all-new UI, enhanced debugging tools like the Interactive Time Travel Debugger, and advanced test execution monitoring. With Linked and Standalone modes, it supports any editor, making it easier than ever to streamline your workflow. Read more in our blog.

Wallaby has been updated to support the latest version of vitest, v2.1.0. This update was necessary due to breaking changes introduced in the latest vitest release.

Wallaby now provides experimental support for the node native testing module, node:test (detailed in our docs). You can now use Wallaby with projects that use node:test, starting from Node v22.3.0 or higher.

We encourage you to report any issues or provide feedback so we can improve this integration.

The latest version of Wallaby significant improves performance startup and test execution times for Jest projects; Jest’s TypeScript configuration files are now transpiled using swc instead of ts-node, and large mono-repos only load project configuration on demand. For large projects, test execution times can be up to 90% faster than before.
