## ⚠️ Warning ⚠️
This workshop material deals with **EXPERIMENTAL** features in React. Please do
not copy/paste any of the code you find here into a production application and
expect it to work. Even when the features are released they may not work the
same as demonstrated in this workshop material.
That said, the concepts in this workshop will very likely be applicable when
these features are stable, so enjoy the workshop!
## NOTICE:
This workshop deals a lot with error boundaries and it's important to note that
create-react-app has a special and helpful "Error Overlay" component that will
sometimes be displayed when an error occurs (whether your app implements error
boundaries or not). For you to see the error handling within the app, you'll
need to close that overlay by clicking the "x" in the upper-right.
## Prerequisites
- Install the React DevTools
([Chrome](https://chrome.google.com/webstore/detail/react-developer-tools/fmkadmapgofadopljbjfkapdkoienihi?hl=en)
(recommended),
[Firefox](https://addons.mozilla.org/en-US/firefox/addon/react-devtools/))
- Watch Dan Abramov's talk
[Beyond React 16 | JSConf Iceland 2018](https://www.youtube.com/watch?v=nLF0n9SACd4)
(33 minutes)
- Experience with React and all hooks
## Quick start
It's recommended you run everything in the same environment you work in every
day, but if you don't want to set up the repository locally, you can get started
in one click with [Gitpod](https://gitpod.io),
[CodeSandbox](https://codesandbox.io/s/github/kentcdodds/react-suspense), or by following the [video demo](https://www.youtube.com/watch?v=gCoVJm3hGk4)
instructions for [GitHub Codespaces](https://github.com/features/codespaces).
[](https://gitpod.io/#https://github.com/kentcdodds/react-suspense)
For a local development environment, follow the instructions below
## System Requirements
- [git][git] v2.13 or greater
- [NodeJS][node] `12 || 14 || 15 || 16 || 17`
- [npm][npm] v6 or greater
All of these must be available in your `PATH`. To verify things are set up
properly, you can run this:
```shell
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][win-path] or
[mac/linux][mac-path].
## Setup
> If you want to commit and push your work as you go, you'll want to
> [fork](https://docs.github.com/en/free-pro-team@latest/github/getting-started-with-github/fork-a-repo)
> 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:
```shell
git clone https://github.com/kentcdodds/react-suspense.git
cd react-suspense
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][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:
```shell
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:
```shell
docker-compose up
```
## Running the app
To get the app up and running (and really see if it worked), run:
```shell
npm start
```
This should start up your browser. If you're familiar, this is a standard
[react-scripts](https://create-react-app.dev/) application.
You can also open
[the deployment of the app on Netlify](https://react-suspense.netlify.app/).
## Running the tests
```shell
npm test
```
This will start [Jest](https://jestjs.io/) 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.
### Exercises
- `src/exercise/00.md`: Background, Exercise Instructions, Extra Credit
- `src/exercise/00.js`: Exercise with Emoji helpers
- `src/__tests__/00.js`: Tests
- `src/final/00.js`: Final version
- `src/final/00.extra-0.js`: Final version of extra credit
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.
### Helpful Emoji 🐨 💰 💯 📝 🦉 📜 💣 💪 🏁 👨💼 🚨
