enable chunk splitting support

[ElPrudi]

Inside a webpack configuration file:

module.exports = {
    optimization: {
        runtimeChunk: true
    }
}

Results in the web service with the error:

Uncaught ReferenceError: require is not defined

I've investigated it a bit more and it seems like general chunk splitting is impossible (or different to other use cases), because this also doesn't work:

module.exports = {
    target: 'web',
    entry: {
        main: 'core-js',
        'visual.js': pluginLocation
    },
    optimization:
        splitChunks: {
            cacheGroups: {
                vendor: {
                    test: /[\\/]node_modules[\\/]/,
                    name: 'vendors',
                    chunks: 'all'
                }
            }
        }
    }
}

also doesn't seem to work.
