A React Developer’s Guide to Hooks

After a long time trying to figure out how hooks work, you finally realize that no one understands the full picture. You’ve seen several ‘How-to-use-react-hooks’ articles, but they all contradict each other, and you still can’t see the big picture.

You feel like something is wrong in your head – like you need to go to a hardware shop and buy bigger RAM or maybe just simpler plugs.

Learn more about the different ways you can use hooks to take your React application development experience to the next level. This new way of writing React components will make your code cleaner and more comfortable to test!


This React Developer’s Guide to Hooks is a guide in 12 lessons to help you:

  • Understand how hooks work
  • Master common patterns
  • Solve recurring problems
  • Use hooks at their full potential


Why this book?

In my experience with React and hooks, I have faced many issues, spent some time debugging to understand where these issues came from, and seen other developers make the same mistakes again and again.

I have also seen several developers during technical tests in job interviews getting lost when using hooks because they needed to go past the primary use of useState and useEffect.

I wrote this guide for developers who already know and use React, maybe even hooks, but would like to use them at their full potential.


100% React

The idea is not to present you dozens of awesome hooks: First, you will only need two, useState and useEffect. First, we’ll deep dive into these two, and then we’ll see some others to solve specific problems. Always by using only React, no third-party libraries.

By buying this guide, you will get:

  • A condensed presentation of hooks and how they work,
  • Concrete common problems with several solutions to fix them,
  • Examples all along, because they are the best way to understand,
  • A list of useful online resources and third-party hooks to go deeper,
  • All in a beautifully presented document (for the PDF version).



Runnable examples

If you choose to purchase the pack with the examples source code, you’ll be able to run them locally on your machine.
