📦 Zero

Help Scout's zero config scripts

Zero is a "zero config" tool designed to make it easy to create, develop, test, build, and publish libraries.

It comes with a bunch of modern front-end tools, like Babel, Rollup, ESLint, Prettier, and Jest - All pre-configured to let you build stuff without fiddling with configuration files, scripts and commands.

Installation

Add Zero to your project with this command:

npm install --save-dev @helpscout/zero

Or globally with:

npm install -g @helpscout/zero

Usage

Zero comes with a handful of scripts that you can add to your own package.json scripts:

"scripts": {
  "prestart": "zero prestart",
  "build": "zero build",
  "format": "zero format",
  "lint": "zero lint",
  "precommit": "zero pre-commit",
  "release": "zero release",
  "test": "zero test",
  "validate": "zero validate",
}

CLI

To use Zero as a CLI, install it globally, then run this command:

zero

Alternatively, you can run it with npx

npx @helpscout/zero

Extending

Zero can build, lint, format, and release out-of-the-box!

If you need to personalize Babel, ESLint, or Jest, Zero's got you covered. Add your own adjustments by extending Zero's based configurations.

Babel

Create a babel or .babelrc file with:

{"presets": ["@helpscout/zero/babel"]}

babel-core@7

As of version 1.0.0, Zero is now on @babel version 7. Your project may need to install [email protected]. To do so, add that package to your package.json, or run:

npm install --save-dev [email protected]

@babel/runtime

Zero does not use @babel/runtime, as it is still being used to compile projects on Babel 6. If you need an ultra-modern Babel 7 ready tool, check out kcd-scripts.

babel-plugin-react-app

Zero no longer comes with babel-plugin-react-app. The reason is because this module uses @babel/runtime with the new Babel 7 set up. If your project requires babel-plugin-react-app (e.g. building Docz), you'll need to add it yourself as a devDependencies.

ESlint

Create an .eslintrc file with:

{"extends": "./node_modules/@helpscout/zero/eslint.js"}

Note: for now, you'll have to include an .eslintignore in your project until this eslint issue is resolved.

Jest

Create a jest.config.js file with:

const jestConfig = require('@helpscout/zero/jest')

module.exports = Object.assign(jestConfig, {
  // your overrides here
})

Prettier

Create a .prettierrc.js file with:

module.exports = require("@helpscout/zero/prettier");

Thanks

Thanks to kcd-scripts and create-react-app for the inspiration and code!
