This is archived. If you want to learn React, I recommend The Beginner's Guide to React as a great free resource and EpicReact.dev as a premium resource that will get you really good at React.
Cheers!

👋 hi there! My name is Kent C. Dodds!
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.
You may be able to work through the entire workshop in the browser. Go to
this codesandbox
and you should be good to go. (Note: there are a few exercises in the intro
folder which you won't be able to run in codesandbox, but don't require
installing any dependencies).
If you'd rather be able to work through the workshop on your own computer, then follow the following instructions.
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:
NOTE:
<branchname>refers to the specific branch you want to clone. Replace that with the branch you were given in the instructions ormainif you were not given any specific instructions.
git clone --single-branch --branch <branchname> https://github.com/kentcdodds/learn-react.git
cd learn-react
npm run setup --silent
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. You may also want to look at Troubleshooting. 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).
To get the app up and running (and really see if it worked), run:
npm startThis 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.
npm testThis will start Jest in watch mode. Read the output and play around with it.
You'll want to start in the intro/exercises directory where we start with
raw React and DOM APIs. Pull open the .html files in your browser and follow
along in the comments.
Once you get through those, then start in the src/exercises directory and
work through those.
Your goal will be to go into each test, swap the final version for the exercise version in the import, and make the tests pass
Each exercise has comments in it to help you get through the exercise. These fun emoji characters are here to help you.
- Kody the Koala Bear 🐨 will tell you when there's something specific you should do
- Marty the Money Bag 💰 will give you specific tips (and sometimes code) along the way
- Hannah the Hundred 💯 will give you extra challenges you can do if you finish the exercises early.
- Olivia the Owl 🦉 will give you useful tidbits/best practice notes and a link for elaboration and feedback.
- Dominic the Document 📜 will give you links to useful documentation
- Berry the Bomb 💣 will be hanging around anywhere you need to blow stuff up (delete code)
- Peter the Product Manager 👨💼 helps us know what our users want
- Alfred the Alert 🚨 will occasionally show up in the test failures with potential explanations for why the tests are failing.
"npm run setup" command not working
Here's what the setup script does. If it fails, try doing each of these things individually yourself:
# verify your environment will work with the project
node ./scripts/verify
# install dependencies
npm install
# verify the project is ready to run
npm run build
npm run test:coverage
If any of those scripts fail, please try to work out what went wrong by the error message you get. If you still can't work it out, feel free to open an issue with all the output from that script. I will try to help if I can.
Thanks goes to these wonderful people (emoji key):
