There are a number of methods to configure Babel. See Babel’s Configuration documentation for more information. To use this preset, simply reference @wordpress/default in the presets option in your Babel configuration.

For example, using .babelrc:

Extending Configuration Extending Configuration

This preset is an opinionated configuration. If you would like to add to or change this configuration, you can do so by expanding your Babel configuration to include plugins or presets which override those included through this preset. It may help to familiarize yourself the implementation of the configuration to see which specific plugins are enabled by default through this preset.

For example, if you’d like to use a new language feature proposal which has not reached the stability requirements of WordPress, you can add those as additional plugins in your Babel configuration:

    "presets": [ "@wordpress/babel-preset-default" ],
    "plugins": [ "@babel/plugin-proposal-class-properties" ]

Code is Poetry.
