    modernPolyfills
    Type: boolean | string[]

    Default: false

    Defaults to false. Enabling this option will generate a separate polyfills chunk for the modern build (targeting browsers with native ESM support).

    Set to a list of strings to explicitly control which polyfills to include. See Polyfill Specifiers for details.

    Note it is not recommended to use the true value (which uses auto-detection) because core-js@3 is very aggressive in polyfill inclusions due to all the bleeding edge features it supports. Even when targeting native ESM support, it injects 15kb of polyfills!

    If you don't have hard reliance on bleeding edge runtime features, it is not that hard to avoid having to use polyfills in the modern build altogether. Alternatively, consider using an on-demand service like Polyfill.io to only inject necessary polyfills based on actual browser user-agents (most modern browsers will need nothing!).
