Available Scripts

Apollo Universal Starter Kit comes with a root package.json file that contains commands you can run for all the packages – web, server, and mobile.

You can run the scripts from the root of your Apollo Universal Starter Kit project:

# project root, typically apollo-universal-starter-kit
yarn build

Alternatively, you can run all the scripts using NPM:

npm run build

Global Scripts in root/package.json

NOTE: Most scripts in apollo-universal-starter-kit/package.json run with Lerna, a tool that enables us to simultaneously run the same scripts for all the packages – client, server, and mobile.

yarn build

Compiles the production application to the packages/server/build, packages/client/build, and packages/mobile/build directories for the server, client, and mobile applications respectively.

yarn clean

Removes the compiled production application files from the packages/server/build, packages/client/build, and packages/mobile/build folders.

yarn start

Runs the Apollo Universal Starter Kit application in production mode. The application will be open in your default browser. The application code is minified and optimized to ensure the best performance.

yarn watch

Runs the app in development mode and watches the changes made to the code with the help of hot code reload.

The yarn watch command has a few specific implementations.

yarn watch-client

Runs the client-side React application in development mode and watches the changes using hot code reload.

This command is especially useful if you're developing a Scala back-end application or your custom back-end app and you don't need the Express application to run. Also note that the server-side rendering is turned off if you run yarn watch-client.

yarn watch:angular

Runs only the Angular frontend application in development mode.

yarn watch:vue

Runs only the Vue frontend application in development mode.

yarn watch:android

Runs only the Android app in development mode.

yarn watch:ios

Runs only the iOS app in development mode.

yarn android

Runs the Expo Android project and the Express back-end application in development mode. The command disables building the project for the web (the React application) and iOS platforms.

yarn ios

Runs the Expo iOS project and the Express back-end application in development mode. The command disables building the project for the web (the React application) and Android platforms.

yarn cli

Runs the Apollo Universal Starter Kit built-in command line interface (CLI). The CLI is currently used for scaffolding and deleting Apollo Starter Kit modules. Consult the CLI guide for more information about yarn cli.

yarn stripe:setup

Generates the Stripe plan for the payment module in Apollo Starter Kit. The default Stripe configuration used for generation of the plan is located in config/stripe/subscription.js.

yarn seed

Seeds the sample data to the SQLite database. You can use the yarn seed --prod command for production mode.

yarn migrate

Migrates the sample database. The command updates the database according to the latest migrations.

yarn rollback

Rolls back the sample database to the previous state. The command simply cancels the last migration created with yarn migrate.

yarn jest

Runs the tests for the mobile app using Jest, a Facebook utility for running unit tests for React Native apps. You can view a demo unit test for mobile in the packages/mobile/src/__tests__ directory.

yarn test

Runs the unit tests with Mocha and the static code checking with TSLint and ESLint.

yarn tests

Runs the unit tests with Mocha and waits until all the tests are executed. The test results will be shown in the console.

yarn tests:watch

Runs the unit tests with Mocha, waits until they're executed, and automatically watches the changes to the tests or application code. Once the changes are made, the tests will re-run (one or more tests will be executed again depending on how many changes you've made).

yarn lint

Runs the ESLint to perform checks for errors in .js, .jsx, .ts, and .tsx files.

yarn heroku-postbuild

Runs various commands specific for Heroku for Apollo Starter Kit client, server, and mobile packages. Once you publish your application on Heroku, this command will run yarn build for the client, server, and mobile packages. For example, after you build the project for Heroku, this command will publish the mobile app: It'll run exp publish, then log in to Expo, compile the mobile builds and publish them on Expo.

yarn precommit

Runs additional checks before the code is committed to Git.

yarn precommit is a utility command that runs each time you commit your changes to Git. You don't need to run this command separately, although doing so won't create any issues.

yarn precommit runs the lint-staged utility to find any changes in .js, .jsx, and .json files and fix errors if any. If changes were made in TypeScript files, then TSLint will run to check the code updates. If linting issues in the files are fixed, the file is committed to Git. During the checks, the code is also forcibly formatted.

When formatting the code isn't possible, however, the changes won't be committed, and the issues (the files and the lines where issues were found) will be shown in the console.
