? Advanced React Patterns ? EpicReact.Dev

Learn how to build simple and flexible React Components and Hooks using
modern patterns

Not only learn great patterns you can use but also the strengths and
weaknesses of each, so you know which to reach for to provide your custom
hooks and components the flexibility and power you need.


System Requirements

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


If you want to commit and push your work as you go, you'll want to
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-patterns
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

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.
