Hi everyone!

We're gradually coming out of the holiday season. There are quite a few blog posts; but no major announcements apart from React-Native 0.71.

I'm back from a ski vacation and back on the weekly newsletter schedule. I didn't follow everything but I think the Twitter drama of the week was about Tailwind? 😅

Only 2 days left to take the State of React-Native survey 🙏

For creative web devs interested in React-Three-Fiber, subscribe to the Web Game Dev newsletter: you will find more info than here.

    useReducer

    A Cure for useState Hell

    Proposes to replace several useState with a useReducer with a single action. He explains the advantages, like the possibility to make sure the state is consistent, or to migrate later to a reducer with several actions. An interesting pattern to know. My opinion: it is quite possible to get similar benefits by using a single useState with a single object and a custom hook. useState or useReducer should be an implementation detail.

    Type-safe React Query

    With TypeScript, you'd rather not fool yourself. Can we trust our backend to return the right payload. Dominik suggests combining React-Query with Zod. With inference, it is no longer necessary to force a type with as or generics. We can use tRPC or Zodios in a fullstack environment when the backend and frontend are in the same monorepo.
