Use custom router or symlinks to avoid code duplication

[Kasheftin]

That's a very interesting and useful article and the code! I noticed that the pages/index.vue, pages/top.vue, and pages/t/_tag.vue use pretty much the same code. It's possible to use the route name or path to determine what has to be shown and avoid code duplication. There're several simple ways to refactor this:

1. Move the pages/index.vue content to components/ArticleList.vue (and get an advantage of the new fetch approach being used in components one more time). Call it from index.vue like that:

   <template>
   <article-list query="tag=nuxt&state=rising" title="New Nuxt.js articles" />
   </template>

2. Use pages/_page.vue as the default route handler and place article list there (but it will require to move authors to the /authors/_username route, and tags to /?tag=.. query).

3. Write the custom router in the nuxt.config.js.

4. Convert pages/index.vue, pages/top.vue and pages/t/_tag.vue to the symlinks that point to the same common_pages/index.vue file and parse the route there manually.

About the 1 way... My mistake, the head method has to be called from the page-level component. Instead of sending title to the ArticleList.vue we could write something like:

<template>
  <article-list :query="query" />
</template>

<script>
export default {
  computed: {
    query() {
      switch (this.$route.name) {
        case 't-tag':
          return `tag=${this.$route.params.tag}&top=365`
        case 'top':
          return 'tag=nuxt&top=365'
        default:
          return 'tag=nuxt&state=rising'
      }
    }
  },
  head() {
    switch (this.$route.name) {
      case 't-tag':
        return {title: `${this.$route.params.tag} articles`}
      case 'top':
        return {title: 'Top Nuxt.js articles'}
      default
        return {title: 'New Nuxt.js articles'}
    }
  }
}
</script>
