An exercise-based minishop by Ben Ilegbodu to learn how to migrate to React Hooks from classes for a better way to develop components and manage state in React applications. Best if accompanied with live facilitation by me 🙂.
In order to maximize our time during the minishop, please complete the following tasks in advance:
- Set up the project (follow setup instructions below)
- Install and run Zoom on the computer you'll be developing with
- Install React Developer Tools for Chrome (recommended) or Firefox
- Install a JSX-friendly code editor, such as Visual Studio Code
- Brush up on modern ES.next features, if they are unfamiliar to you
- Have experience building React applications using class components
The more prepared you are for the minishop, the better it will go for you! 👍🏾
All of these must also be available in your PATH
in order to be run globally. To verify things are set up properly, run:
git --version
node --version
npm --version
If your node version is version 9 or lower, you can install nvm
to manage multiple versions of node.
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 have verified that you have the proper tools installed (and at the proper versions), getting setup should be a breeze. Run the following commands:
git clone https://github.com/benmvp/migrate-react-hooks-minishop.git
cd migrate-react-hooks-minishop
npm run setup
This will likely take a few minutes to run. It will clone the repo, verify the environment, and install all of the JavaScript dependencies needed to build our app.
If it fails, please read through the error logs and see if you can figure out what the problem is. Double check that you have the proper system requirements installed. If you are unable to figure out the problem on your own, please feel free to file an issue with everything (and I mean everything) from the output of the commands you ran.
We will go through several exercises converting components written in classes to hooks. To get started and verify that everything has been installed correctly, run:
npm start
The app should pop up in your default browser running at http://localhost:3000/. The app should display an index page with links to the steps in the minishop.
For those interested, the app is a standard app bootstrapped by Create React App.
Let's learn about React Hooks! ⚛️

Each step in the minishop contains exercises to apply what you just learned. You will be migrating classes to new code using hooks. There are also bonuses if you've got extra time. The exercises are intended to be a lot, so don't worry if you don't finish them all.
If at any point you get stuck, you can find the answers in the answers/
directory of the step.
- 🛠️ Setup / Logistics / Intro
- Step 1 - State
- Step 2 - Effects
- 😴 10 minutes
- Step 3 - Context
- Step 4 - Custom hooks
- ❓ Q & A
- Final Quiz!
- 👋🏾 Goodbye!
- Please interrupt me and ask questions! Others likely will have the same question.
- However, unrelated questions are best sent to Twitter.
- Keep your video on (if possible) to make it feel more human and lively
- Keep your microphone muted unless your talking to avoid background noise distractions
- Answer each other's questions in the chat
- Use breakout rooms for help
Here is what you'll come away knowing at the end of the minishop...
- Defining function components (Step 1)
- Rules of hooks (throughout)
- Maintaining UI state with the
useState
hook instead ofsetState
(Step 1) - Managing side effects with/without cleanup using the
useEffect
hook instead of lifecycle methods (Step 2) - Passing down and updating context with the
useContext
hook (Step 3) - Sharing component logic by creating custom hooks (Step 4)
Each step has an Elaboration & Feedback form link at the end. After you're done with the exercise and before jumping to the next step, please take a few minutes to fill out the form to solidify your learning.
At the end of the minishop, I would greatly appreciate your overall feedback. Share your minishop feedback.
