babel-preset-y

The Babel preset used within Y Software AB.

In your project's .babelrc.js

module.exports = {
  presets: [
    ['y', {
      // debug: false,
      // loose: false,
      // spec: false,
      // useBuiltIns: true,
      // 'preset|plugin': {...options}
    }]
  ]
};

Optionally, you can run node_modules/babel-preset-y/npm-install-peer-dependencies in order to install the required peer dependencies.

NOTE If you're using an earlier version than Babel 7.0, you can upgrade your .babelrc to be dynamic and use .babelrc.js by setting it to:

{
  "preset": [
    "./.babelrc.js"
  ]
}

See https://fatfisz.com/blog/using-babelrc-js-today .

Options

Pass debug, loose, spec or useBuiltIns to configure presets/plugins, as per the semantics defined by babel-preset-env.

Included presets/plugins can be

• further configured by sending options to each of them
• disabled by sending {"disabled": true} as options
