npm run start
Starts the development server running on http://localhost:3000
npm run clean
Deletes the example app, replacing it with the smallest amount of boilerplate code necessary to start writing your app!
Note: This command is self-destructive, once you've run it you cannot run it again. This is for your own safety, so you can't delete portions of your project irreversibly by accident.
npm run generate
Allows you to auto-generate boilerplate code for common parts of your
application, specifically components, containers, and routes. You can
also run npm run generate <part> to skip the first selection. (e.g. npm run generate container)
npm start
Starts the development server and makes your application accessible at
localhost:3000. Tunnels that server with ngrok, which means the website
accessible anywhere! Changes in the application code will be hot-reloaded.
npm run start:prod
Starts the production server, configured for optimal performance: assets are minified and served gzipped.
To change the port the app is accessible at pass the --port option to the command
with --. E.g. to make the app visible at localhost:5000, run the following:
npm start -- --port 5000
npm run build
Preps your app for deployment. Optimizes and minifies all files, piping them to
a folder called build. Upload the contents of build to your web server to
see your work live!
See the testing documentation for detailed information about our testing setup!
npm run test
Tests your application with the unit tests specified in the *test.js files
throughout the application.
All the test commands allow an optional -- --grep string argument to filter
the tests ran by Karma. Useful if you need to run a specific test only.
# Run only the Button component tests
npm run test:watch -- --grep Button
To choose the browser to run your unit tests in (Chrome by default), run one of the following commands:
npm run test:firefox
npm run test:safari
Windows only!
npm run test:ie
npm run test:watch
Watches changes to your application and reruns tests whenever a file changes.
npm run start:tunnel
Starts the development server and tunnels it with ngrok, making the website
available on the entire world. Useful for testing on different devices in different locations!
npm run pagespeed
With the remote server running (i.e. while npm run start:prod is running in
another terminal session), enter this command to run Google PageSpeed Insights
and get a performance check right in your terminal!
npm run analyze
This command will generate a stats.json file from your production build, which
you can upload to the webpack analyzer. This
analyzer will visualize your dependencies and chunks with detailed statistics
about the bundle size.
npm run lint
Lints your JavaScript and CSS.
npm run lint:js
Only lints your JavaScript.
npm run lint:css
Only lints your CSS.
