Runtime

A plugin type: Programatically insert assets out of thin air into bundles

Runtimes accept a bundle and return assets to be inserted into that bundle.

import { Runtime } from "@parcel/runtime";

export default new Runtime({
  async apply({ bundle, bundleGraph }) {
    // ...
    return assets;
  },
});
