Configure nuxt.js application to work in a subdirectory on a webserver

To complete @Aldarund answer, I use :

export default {
[…] // some code
  router: {
    base:
      process.env.NODE_ENV === "development" ? process.env.BASE_URL : "/<subfolder>/"
  } // where <subfolder> is the subfolder!
};

You need router/base

router: {
  base: '/dist/'
}
