@babel/plugin-external-helpers

Externalizing Babel Helpers

This configuration in your Babel setup will enable the use of external helpers. Instead of including Babel's helper functions in every file, they will be imported from an external source, reducing redundancy and potentially decreasing the bundle size.

module.exports = {
  plugins: [
    '@babel/plugin-external-helpers'
  ]
};

Using with a Custom Helper Library

You can specify a custom version of the helper library to use. This is useful if you have a specific version of Babel's helpers that you want to ensure compatibility with.

module.exports = {
  plugins: [
    ['@babel/plugin-external-helpers', {
      helperVersion: '7.0.0'
    }]
  ]
};
