AngularJs Multiple Times loaded

Question

I have a problem with upgrade my angularJs Application to Webpack4.

this is my setup:

vendor.ts

import "angular";
import "angular-i18n/de-de";
import "angular-route";

and

main.ts
import {MyAppModule} from "./my-app.app";

angular.element(document).ready(() => {
    angular.bootstrap(document.body, [MyAppModule.name], { strictDi: true });
});

With webpack 3. I had a commonsChunkPlugin and everything worked.

With webpack 4, I'm using the splitChunks option to not import angularjs 5 times:

webpack.config.ts
...
optimization: {
    splitChunks: {
        cacheGroups: {
            commons: {
                name: "commons",
                chunks: "initial",
                minChunks: 2
            }
        }
    }
}
...

That is working correctly. I have loaded the angularjs code only in my common.js file. But unfortunatelly the code is instantiated twice, so the app always logs the warning:

WARNING: Tried to load AngularJS more than once.

The chunks are loaded via HtmlWebpackPlugin in the html.

Any idea how to remove the warning?

Found the solution in the deeps of github issues:

The vendor file should not be an entry point but the entry point should be a list of files:

...
 entry: {
    main: ['./vendor.js', './main.js']
},
...
