Description

React Query (also called TanStack Query) has become the go-to solution for server state management in React apps, and for good reason! This smart, comprehensive solution makes it easy to keep your app up-to-date with data on the server.

In fact, if you are using Redux simply to manage data from the server, React Query can replace Redux in your app. And, for server data management, React Query is much simpler and more powerful than Redux. For example, React Query:

tracks loading and error states for your server queries (no need to manage that yourself!)
makes cached server data available for display while you’re fetching updated data

This course starts with a simple app to learn the basics of React Query version 3:

queries – React Query / TanStack Query
loading and error states
React Query dev tools
pagination and pre-fetching
mutations

Then we take a detour with the Star Wars API to learn about Infinite Queries (getting more data just as the user has gotten near the end of the current data).

Finally, we work on a large, multi-component app to learn about the above in more detail, plus

centralizing loading and error handling
filtering data
integrating React Query with auth
ways to keep data up to date after mutations, including optimistic updates
testing React Query – React Query / TanStack Query

Other notable course features:

pre-written projects to use as a backdrop for React Query, so there’s no time wasted writing code not relevant to the course
ample opportunities to practice with periodic “code quizzes” to make sure you’re understanding the concepts
visual models for complicated concepts to help understand all of the moving pieces
the major project is written in TypeScript
supportive instructor who loves engaging with students in Q&A

Come see what the hype is about, and improve your apps with simpler, more powerful server state management!
