Mirage JS is an API mocking library that lets you build, test and share a complete working JavaScript application without having to rely on any backend services.
Create a Server
The
best DX for frontend development.
Say goodbye to configuring painful backend environments just to hack on your UI. Mirage runs alongside the rest of your frontend code, so there’s no new infrastruture for you to learn.
New collaborators can clone your frontend codebase, run npm install, and have a complete local offline dev environment up and running in seconds – no environment variables or auth tokens needed.
Honestly, I can't recommend this tool enough. Finally, an idiomatic way for frontend developers to prototype and test an entire feature without touching a real API! Productivity just goes through the roof.
Developer at 0588 tech
Write high-level UI tests that stress your networking code.
With Mirage, you can write automated tests against your API no matter what state it’s in. Test how your app handles 0 blog posts, 17, or – – or even how it behaves when your server is slow or responds with an error.
No messy mocking code or handcrafted API respones in your tests. Just real-world scenarios validating the entire functionality of your full application.
