@volvo-cars/vcc-scripts

Wraps build, test, lint and formatting tools and keeps them up to date for you.

Basic usage

yarn add @volvo-cars/vcc-scripts

Example package.json

{
  "main": "lib/index.js",
  "module": "es/index.js",
  "files": ["lib", "es"],
  "scripts": {
    "build": "vcc-scripts build",
    "lint": "vcc-scripts lint",
    "format": "vcc-scripts format",
    "test": "vcc-scripts test"
  },
  "devDependencies": {
    "vcc-scripts": "^0.0.5"
  }
}

build

Runs Babel on a package, using fields from package.json as configuration. See vcc-scripts build --help for more information.

• Compiles src/ to CommonJS modules to the dirname of package.json#main.
• Compiles src/ to ES modules to the dirname of package.json#module, if it exists.
• Compiles src/ to ES modules for modern browsers to the dirname of package.json#esnext, if it exists.
• Outputs TypeScript definition files to the dirname of package.json#types, if it exists and the package has a tsconfig.json.

@volvo-cars/babel-preset-react-app is used as the Babel configuration. You can add your own plugins with a .babelrc file that will be merged into the default configuration, but please send a pull request to the Babel preset if your change might benefit others.

To avoid including duplicated helper functions in your compiled code, run yarn add @babel/runtime to use the shared Babel runtime and vcc-scripts will adjust the Babel config.

Example package.json

{
  "main": "lib/index.js",
  "module": "es/index.js",
  "esnext": "esnext/index.js",
  "types": "types/index.d.ts",
  "files": ["lib", "es", "esnext", "types"],
  "scripts": {
    "build": "vcc-scripts build",
    "build:watch": "vcc-scripts build --watch"
  },
  "dependencies": {
    "@babel/runtime": "^7.4.0"
  }
}

test

Runs Jest with a default configuration. See vcc-scripts test --help for more information.

Any additional arguments will be passed through to the Jest cli.

Commonly used setup scripts are added automatically, such as a Google Analytics global and @testing-library/jest-dom/extend-expect. To add your own setup scripts, use the --setupFiles or --setupFilesAfterEnv options.

Example package.json

{
  "scripts": {
    "test": "vcc-scripts test --coverage --setupFiles ./testing/setup.js",
    "test:watch": "vcc-scripts test --watch --setupFiles .//testing/setup.js"
  }
}

lint

Runs eslint with the official Volvo Cars eslint configurations without having to install eslint or configurations separately. See vcc-scripts lint --help for more information.

Any additional arguments will be passed through to the eslint cli.

You can add your own configuration with custom .eslintrc files in sub-folders.

For your editor plugins to pick up the correct eslint config, create an .eslintrc.js in the root of your project with

module.exports = require('@volvo-cars/vcc-scripts/config/eslint.js');

Example package.json

{
  "scripts": {
    "lint": "vcc-scripts lint",
    "lint:fix": "vcc-scripts lint --fix"
  }
}

format

Runs prettier with the official Volvo Cars configuration without having to install prettier or configuration separately.

For your editor to pick up the correct prettier config, create a .prettierrc file with "@volvo-cars/prettier-config" in your project root.

Example package.json

{
  "scripts": {
    "format": "vcc-scripts format",
    "format:check": "vcc-scripts format --dry-run"
  }
}
