The 3-file pattern that let me ditch the backend during React Native development
typescript
dev.to
Every time I started a new React Native project I hit the same wall — I needed a backend to test anything. So I'd spin up a local server, hack inline mocks, or just wait. None of those are good. After a few projects I settled on this.
