⚠️ WARNING: Since the upgrade to Babel 7 is incompatible with Parcel v1, CRAP is not supported for the time being until Parcel v2 is out and we can upgrade everything together (or if you want, send a PR to help!). With v0.0.38 we have reverted things to Babel 6 so that at least CRAP is working again :)

Create React App Parcel πŸ’©

create react apps with parcel instead of webpack cos why not

Preconfigured Features that come with your Parcel setup:

  • babel-preset-react-app so you can use the exact same JS features that come with create-react-app (eg public class fields)
  • improved App.js to show off the babel preset features (click on the React logo!)
  • serviceWorker available but off by default (similar to the coming create-react-app 2.0 setup)
  • preconfigured build setup based on the ParcelJS API
  • nice eject experience that doesnt saddle you with a million webpack plugins
  • as far as possible, same DX as create-react-app (eg checks if you use yarn or npm, environment variables all the same)
    • in particular it's a fork of create-react-app v2.0 so you also get features like babel-plugin-macros for free! πŸ”₯

Using C.R.A.P.

npx create-react-app-parcel my-app

## or install it:
# npm i -g create-react-app-parcel
# crap my-app

cd my-app
yarn start

and presto! (try clicking the react icon)

C.R.A.P. structure

You will have a very simple folder structure, same as create-react-app:

my-app
β”œβ”€β”€ README.md
β”œβ”€β”€ node_modules
β”œβ”€β”€ package.json
β”œβ”€β”€ .gitignore
β”œβ”€β”€ public
β”‚   └── favicon.ico
β”‚   └── index.html
β”‚   └── manifest.json
└── src
    └── App.css
    └── App.js
    └── App.test.js
    └── index.css
    └── index.js
    └── logo.svg
    └── registerServiceWorker.js

No configuration or complicated folder structures, just the files you need to build your app.


react-scripts-parcel API guide

npm start or yarn start

Runs the app in development mode.
Open http://localhost:1234 to view it in the browser.

The page will automatically reload if you make changes to the code.
You will see the build errors and lint warnings in the console.

npm test or yarn test

⚠️ warning: this functionality is untested for now

npm run build or yarn build

Builds the app for production to the dist folder.
It correctly bundles React in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes.

Your app is ready to be deployed.

yarn eject

ejects you out of this shiznit like so

There's this dinky little me-too project called create-react-app, send them some love, who knows they could be big someday.
