👋 hi there! My name is Kent C. Dodds and this is the source material for Build a ReactJS App!

NOTE: This repository is used for a multi-part workshop

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

• 📺 only necessary if the workshop is remote via Zoom

• 👋 specific to the material for this workshop

• 3️⃣ Only needed to prepare for part 2 of 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 How to get the bookshelf app setup (~18 minutes). Please do NOT skip this step.

• 👋 Watch The Beginner's Guide to React (available free on Egghead.io), or have the equivalent experience (147 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.

• 👋 3️⃣ Go through my Advanced React Hooks, or have the equivalent basic experience of using advanced hooks. You should be experienced with useContext, useReducer, useMemo, and useCallback.

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

• 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/bookshelf.git
cd bookshelf
npm run setup --silent

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).

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 production deployment: bookshelf.lol.

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.

Snuggle up next to the 🔥 with a good 📚

This workshop is a bit different from my other workshops. The exercises are much longer and you'll have more time to complete them. We'll also be taking breaks mid-exercise, wherever there's a need. So consider this schedule to be very loose.

The exercises are in different branches. Each branch changes the INSTRUCTIONS.md file to contain instructions you need to complete the exercise.

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.

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.

• Checkout the exercise branch
• Read through the INSTRUCTIONS.md
• Start exercise
• Go through every mentioned file and follow the instructions from the emoji
• We all come back together
• I go through the solution and answer questions
• Move on to the next exercise.
• Repeat.
