Question

Vue.js

Using Vue UIcreated a template project, the only thing - added vue.config.jsand variables.scss. The assembly goes as expected, but the final index.htmlfiles are connected 2 times.
vue.config.js

module.exports = {
    productionSourceMap: false,
    css: {
        loaderOptions: {
            sass: {
                data: `@import "[email protected]/variables.scss";`
            }
        }
    }
}

Answer 1

In principle, Alexander Aksentiev has already given you an exhaustive answer.
You can optionally disable these plugins in webpack by adding the following to vue.config.js:

{
    ...
    chainWebpack: config => {
        config.plugins.delete('prefetch');
        config.plugins.delete('preload');
    },
    ...
}
