Ultimate Guide to Performant Custom Data Fetching in React

It's a course that will show you how to fetch data efficiently in React without a third party library or the use effect hook.

This course was produced for mid to senior developers. Library authors, and those want to fetch data in a performant way.

Fetching data is such a crucial part of building React applications, and not doing it correctly could lead to slower applications for many reasons like:

    - Refetching data that hasn't changed which should be cached
    - Fetching data again that is currently being fetched
    - Not fetching data before a component is rendered
    - Fetching data on hover or focus

    And many other reasons.

If you have an existing project that is using a data fetching library, you may not need to create something custom. However, if you are building a new project or want to improve the performance of an existing project, and want to have more control over how data is fetched, then creating something custom is the way to go.

    Or if you simply want a better understanding of data fetching issues and how to solve them, then creating something custom is a great way to learn.

React is a great library for building user interfaces and it gives a great set of utilities. But when it comes to doing something specific, the recommendation is usually to reach for a library. However, for those who want to dig deeper and understand how things work a library isn't really helpful.

    This course was inspired by the need for developers to understand how data fetching in React works, the common issues that arise, and the best ways to solve them.

At the time of creating this course React 19 was not released.However the code works with React 18.3.1 and passed all the React Compiler health checks.
