  • You should be experienced with useState, useEffect, and useRef.

Additional Resources

System Requirements

  • git v2.13 or greater
  • NodeJS 12 || 14 || 15 || 16
  • npm v6 or greater

All of these must be available in your PATH. To verify things are set up properly, you can run this:

git --version
node --version
npm --version

If you have trouble with any of these, learn more about the PATH environment variable and how to fix it here for windows or mac/linux.


If you want to commit and push your work as you go, you'll want to fork first and then clone your fork rather than this repo directly.

After you've made sure to have the correct things (and versions) installed, you should be able to just run a few commands to get set up:

git clone
cd advanced-react-hooks
node setup

This may take a few minutes. It will ask you for your email. This is optional and just automatically adds your email to the links in the project to make filling out some forms easier.

If you get any errors, please read through them and see if you can find out what the problem is. If you can't work it out on your own then please file an issue and provide all the output from the commands you ran (even if it's a lot).

If you can't get the setup script to work, then just make sure you have the right versions of the requirements listed above, and run the following commands:

npm install
npm run validate

If you are still unable to fix issues and you know how to use Docker 🐳 you can setup the project with the following command:

docker-compose up

It's recommended you run everything locally in the same environment you work in every day, but if you're having issues getting things set up, you can also set this up using GitHub Codespaces (video demo) or Codesandbox.

Running the app

To get the app up and running (and really see if it worked), run:

npm start

This should start up your browser. If you're familiar, this is a standard react-scripts application.

You can also open the deployment of the app on Netlify.

Running the tests

npm test

This will start Jest in watch mode. Read the output and play around with it. The tests are there to help you reach the final version, however sometimes you can accomplish the task and the tests still fail if you implement things differently than I do in my solution, so don't look to them as a complete authority.

The purpose of the exercise is not for you to work through all the material. It's intended to get your brain thinking about the right questions to ask me as I walk through the material.
