Command Line Commands

Initialization

$ npm run setup

Initializes a new project with this boilerplate. Deletes the react-boilerplate git history, installs the dependencies and initializes a new repository.

Note: This command is self-destructive, once you've run it the init script is gone forever. This is for your own safety, so you can't delete your project's history irreversibly by accident.

Cleaning

$ 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.

Generators

$ npm run generate

Allows you to auto-generate boilerplate code for common parts of your application, specifically components, containers, selectors, sagas and routes.

Server

Development

$ 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.

Production

$ npm run start:prod

Starts the production server, configured for optimal performance: assets are minified and served gzipped.

Port

To change the port the app is accessible at pass the -p option to the command with --. E.g. to make the app visible at localhost:5000, run the following: $ npm start -- -p 5000

Building

$ 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!

Testing

See the testing documentation for detailed information about our testing setup!

Unit testing

$ npm run test

Tests your application with the unit tests specified in the *test.js files throughout the application.

Browsers

To choose the browser to run your unit tests in (Chrome by default), run one of the following commands:

Firefox

$ npm run test:firefox

Safari

$ npm run test:safari

Internet Explorer

Windows only!

$ npm run test:ie

Watching

$ npm run test:watch

Watches changes to your application and reruns tests whenever a file changes.

Remote testing

$ 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!

Note: $ npm start aliases to this command.

Performance testing

$ npm run pagespeed

With the remote server running (i.e. while $ npm run serve is running in another terminal session), enter this command to run Google PageSpeed Insights and get a performance check right in your terminal!

Dependency size test

$ 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.

Linting

$ npm run lint

Lints your JavaScript and CSS.

JavaScript

$ npm run lint:js

Only lints your JavaScript.

CSS

$ npm run lint:css

Only lints your CSS.
