• Text editor or IDE pre-configured with React/JSX/Flow/ESlint (learn more)

Before you start, take a moment to see how the project structure looks like:

This will install both run-time project dependencies and developer tools listed in package.json file.

This command will build the app from the source files (/src) into the output /build folder. As soon as the initial build completes, it will start the Node.js server (node build/server.js) and Browsersync with HMR on top of it.

https://localhost:3000/ — Node.js server (build/server.js)
https://localhost:3000/graphql — GraphQL server and IDE
https://localhost:3001/ — BrowserSync proxy with HMR, React Hot Transform
https://localhost:3002/ — BrowserSync control panel (UI)

Now you can open your web app in a browser, on mobile devices and start hacking. Whenever you modify any of the source files inside the /src folder, the module bundler (Webpack) will recompile the app on the fly and refresh all the connected browsers.

Note that the yarn start command launches the app in development mode, the compiled output files are not optimized and minimized in this case. You can use --release command line argument to check how your app works in release (production) mode:

$ yarn start -- --release

NOTE: double dashes are required

If you need just to build the app (without running a dev server), simply run:

$ yarn run build

or, for a production build:

$ yarn run build -- --release

or, for a production docker build:

$ yarn run build -- --release --docker

NOTE: double dashes are required

After running this command, the /build folder will contain the compiled version of the app. For example, you can launch Node.js server normally by running node build/server.js.

To check the source code for syntax errors and potential issues run:

$ yarn run lint

To launch unit tests:

$ yarn run test          # Run unit tests with Mocha
$ yarn run test:watch    # Launch unit test runner and start watching for changes

By default, Mocha test runner is looking for test files matching the src/**/*.test.js pattern. Take a look at src/components/Layout/Layout.test.js as an example.

To deploy the app, run:

$ yarn run deploy

The deployment script tools/deploy.js is configured to push the contents of the /build folder to a remote server via Git. You can easily deploy your app to Azure Web Apps, or Heroku this way. Both will execute yarn install --production upon receiving new files from you. Note, you should only deploy the contents of the /build folder to a remote server.
