A minimum viable React app with Parcel Bundler.
Clone and install deps
git clone git@github.com:jaredpalmer/react-parcel-example.git
cd react-parcel-example
yarn
yarn start
Then open http://localhost:1234 and edit index.js and press save. Parcel will automagically hot reload you files whenever you make changes.
npm run build
This will compile your JS and copy your index.html to the dist folder which you can deploy whereever as as a good ol' webpage.
Note: There is a bug in Parcel right now messing up minified builds with uglifyjs
