# Command Line Commands ## Initialization ```Shell 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. ## Development ```Shell npm run start ``` Starts the development server running on `http://localhost:3000` ## Cleaning ```Shell 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 ```Shell npm run generate ``` Allows you to auto-generate boilerplate code for common parts of your application, specifically `component`s, and `container`s. You can also run `npm run generate ` to skip the first selection. (e.g. `npm run generate container`) ## Server ### Development ```Shell npm start ``` Starts the development server and makes your application accessible at `localhost:3000`. Changes in the application code will be hot-reloaded. ### Production ```Shell npm run start:production ``` - Runs tests (see `npm test`) - Builds your app (see `npm run build`) - Starts the production server (see `npm run start:prod`) The app is built for optimal performance: assets are minified and served gzipped. ### Host and Port To change the host and/or port the app is accessible at, pass the `--host` and/or `--port` option to the command with `--`. E.g. to make the app visible at `my-local-hostname:5000`, run the following: `npm start -- --host my-local-hostname --port 5000` ## Building ```Shell npm run build ``` Preps your app for deployment (does not run tests). Optimizes and minifies all files, piping them to the `build` folder. Upload the contents of `build` to your web server to see your work live! ## Testing See the [testing documentation](../testing/README.md) for detailed information about our testing setup! ## Unit testing ```Shell npm test ``` Tests your application with the unit tests specified in the `**/tests/*.js` files throughout the application. All the `test` commands allow an optional `-- [string]` argument to filter the tests run by Jest. Useful if you need to run a specific test only. ```Shell # Run only the Button component tests npm test -- Button ``` ### Watching ```Shell npm run test:watch ``` Watches changes to your application and re-runs tests whenever a file changes. ### Remote testing ```Shell npm run start:tunnel ``` Starts the development server and tunnels it with `ngrok`, making the website available worldwide. Useful for testing on different devices in different locations! ### Dependency size test ```Shell npm run analyze ``` This command will generate a `stats.json` file from your production build, which you can upload to the [webpack analyzer](https://webpack.github.io/analyse/) or [Webpack Visualizer](https://chrisbateman.github.io/webpack-visualizer/). This analyzer will visualize your dependencies and chunks with detailed statistics about the bundle size. ## Linting ```Shell npm run lint ``` Lints your JavaScript and your CSS. ```Shell npm run lint:eslint:fix -- . ``` Lints your code and tries to fix any errors it finds.
