👋 hi there! My name is Kent C. Dodds! This is a workshop repo to teach you about using React Component Patterns to make your react components and hooks more useful and reusable without sacrificing simplicity.

In order for us to maximize our efforts during the workshop, please complete the following things to prepare.

• 📺 indicates steps that are only necessary if the workshop is remote via Zoom

• 👋 indicates steps that are specific to the material for this workshop

• 👋 Setup the project (follow the setup instructions below) (~5 minutes)

• 📺 Install and setup Zoom on the computer you will be using (~5 minutes)

• 📺 Watch Use Zoom for KCD Workshops (~8 minutes).

• Watch Setup and Logistics for KCD Workshops (~24 minutes). Please do NOT skip this step.

• 👋 Watch The Beginner's Guide to React (available free on Egghead.io), or have the equivalent experience (77 minutes)

• 👋 Watch my talk Why React Hooks (35 minutes)

• 👋 Go through my Learn React Hooks Workshop, or have the equivalent basic experience of using hooks. You should be experienced with useState, useEffect, and useRef.

• 👋 Go through my Advanced React Hooks Workshop, or have the equivalent experience. You should be experienced with useContext and useReducer (experience with useMemo and useCallback is a bonus).

The more prepared you are for the workshop, the better it will go for you.

Here are the patterns we'll be covering:

• Context Controller
• Compound Components
• State Reducers
• Controlled Props
• Prop Collections
• Prop Getters

• git v2 or greater
• NodeJS v10 or greater
• 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.

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 https://github.com/kentcdodds/advanced-react-patterns.git
cd advanced-react-patterns
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. 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).

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 that sometimes people have trouble with codesandbox not working quite right with tests, but you should be able to work around that. If you're concerned, then it would probably be better to just set things up locally.

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.

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.

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
• Matthew the Muscle 💪 will indicate what you're working with an exercise
• Chuck the Checkered Flag 🏁 will indicate that you're working with a final version
• 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.

Thanks goes to these wonderful people (emoji key):
