I have a NuxtJS site with only one page /pages/matrix/index.vue but quite a lot of dynamic routes pointing to this page, each route using the same set of data. When generating a static build for deployment on Netlify, the dist folder currently reaches ~1.2 GB, consisting of

• 3125 .html files in dist/matrix (occupying ~39% of the space)
• 3125 folders for payload.js files in dist/_nuxt/static/[random]/matrix/ in subfolders for routes (occupying ~61% of the space)

Those 61% are 3125 copies of a 220kB payload.js with exactly the same set of data: [{}], while only the route changes:

__NUXT_JSONP__("/matrix/place2/time3,time14,time29", (function(a, b, ...) {
    return {
        data: [{ /* data does not change */ }],
        fetch: {},
        mutations: void 0
    }
}("nor", "does", "this")));

I wonder if there is a way to reduce this redundancy by somehow extracting the data part? Reducing ~665 MB to just 220kB sounds alluring.

Some more background:

Routes are /matrix, /matrix/place1 or /matrix/place8/time1,time7,time18. When generating, I pull all data from a headless CMS and feed it to my page component via the payload option. First, I used File System Routing and imported the pages/matrix/index.vue like this:

// pages/matrix/_places/index.vue
<script>
  import Index from '../index'
  export default Index
</script>

which felt wrong but worked. I blamed this approach to the "duplication" of those payload files (frankly without completely understanding the mechanics of static generation). I now switched to extendRoutes with this nuxt.config.js setting:

router: {
  extendRoutes (routes, resolve) {
    routes.push(
      {
        name: 'matrix-place-times',
        path: '/matrix/:place/:times',
        component: resolve(__dirname, 'pages/matrix/index.vue')
      },
      {
        name: 'matrix-place',
        path: '/matrix/:place',
        component: resolve(__dirname, 'pages/matrix/index.vue')
      }
    )
  }
}

The amount of payload files spread across route subfolders stays the same.
Any advice on this? Using Nuxt v2.15.7.
