Vue-Cli: ‘title’ option for htmlWebpackPlugin does not work

Unfortunately the above answers didn’t help me.
As stated in the offical documentation you only need to add the vue.config.js to your root folder and add the following:

    // vue.config.js
    module.exports = {
      chainWebpack: config => {
        config
        .plugin('html')
        .tap(args => {
          args[0].title="Your new title"
          return args
        })
      }
    }

Keep in mind that you have to stop the App and start again with npm run serve. This worked for me.
