How to preload a single bundle generated in Webpack 4?

Question

webpack

Webpack 3 example: https://github.com/Ni55aN/allmatter/blob/master/we...
The splash.js module is generated separately and executed in the head.
If you try to transfer this to Webpack 4 by replacing the plugin, you get the following:
splash.js is not executed in the head, but only when all bundles are loaded, although it is necessary that it be executed before loading.
What has been tried:

entry: {
            splash: './src/splash.js',
            app: './src/app.js'
        },

optimization: {
            splitChunks: {
                cacheGroups: {
                    commons: {
                        chunks: 'all',
                        minChunks: 2,
                        maxInitialRequests: 5,
                        minSize: 0
                    },
                    vendor: {
                        test: /node_modules/,
                        chunks: 'initial',
                        name: 'vendor',
                        priority: 10,
                        enforce: true
                    }
                }
            }
        },

You do something interesting yourself and don’t bring it to the university, but ask your supervisor for the topic of your diploma.
