Example app combining a React UI (from [create-react-app](https://github.com/facebookincubator/create-react-app)) with a custom Node/Express server.
If you simply want to deploy a React app, try [create-react-app-buildpack](https://github.com/mars/create-react-app-buildpack).

## Design Points
* Node server
* [Node server](server/)
* [`package.json`](package.json), at the root
* `postinstall` script performs React app's `npm install` on deploy to Heroku
* `cacheDirectories` includes `react-ui/node_modules/` to speed up subsequent deploys to Heroku
* serves `../react-ui/build/` as static files
* `npm` works normally
* React app
* [React app](react-ui/)
* [`react-ui/package.json`](react-ui/package.json), in a subdirectory
* as generated by create-react-app
* plus the `proxy` config enables dual-process (hot-reloading React UI + Node API) for local development
* `npm` must be run against the subdirectory
* use the prefix option, `npm start --prefix react-ui`, or
* change directories `cd react-ui/` to use `npm`
* Heroku
* **heroku/node** buildpack will auto-detect via `package.json`
* `npm install` for server & `postinstall` for React UI will automatically run
* `npm start` will automatically launch
* [deploy to Heroku](https://devcenter.heroku.com/categories/deployment)
* automatically:
* detects [Node](https://elements.heroku.com/buildpacks/heroku/heroku-buildpack-nodejs) from `package.json`
* builds with `npm install` for server & `postinstall` for React UI
* launches web process with `npm start`
