saber-plugin-query-posts

Query posts and inject them to specific pages. Useful when you're writing a blog.

Install

yarn add saber-plugin-query-posts

Usage

In your saber-config.yml:

plugins:
  - resolve: saber-plugin-query-posts

Then this plugin will inject all posts to pages whose attribute injectAllPosts is set to true, for instance you can create a pages/index.md:

---
layout: index
injectAllPosts: true
---
 
Welcome to my homepage.

Then in the layout component layouts/index.vue, page.posts and page.pagination will be available:

<template>
  <div>
    <slot name="default" />
 
    <ul>
      <li v-for="post in page.posts" :key="post.permalink">
        <a :href="post.permalink">
          {{ post.title }}
        </a>
      </li>
    </ul>
 
    <a :href="page.pagination.prevLink" v-if="page.pagination.hasPrev">
      ← Prev Page
    </a>
    <a :href="page.pagination.nextLink" v-if="page.pagination.hasNext">
      Next Page →
    </a>
  </div>
</template>
 
<script>
export default {
  props: ['page']
}
</script>

Draft Posts

Posts with front matter draft: true will be excluded in page.posts, but they will still be built and accessible via permalink.

Tags

This plugin will automatically generate tag pages at /tags/:tag when you're using tags in page data, e.g. in a Markdown post:

---
title: hello
date: 2019-01-01
tags:
  - life
  - random
---
 
hello

Data Injected in Post Pages

You can access the detailed info of the tags of a post page via this.page.tagsInfo, for instance:

tags:
  - life
  - random

gives you:

;[
  {
    name: 'life',
    permalink: '/tags/life'
  },
  {
    name: 'random',
    permalink: '/tags/random'
  }
]

Tag Layout

Tag pages will use the tag layout or fallback to default layout.

You can access the tag name in the layout component via this.page.tag.

Categories

This plugin will automatically generate category pages at /categories/:tag when you're using categories in page data, e.g. in a Markdown post:

---
title: hello
date: 2019-01-01
categories:
  - sports
---
 
hello

Then there will be a /categories/sports page，categories is an array, so you can assign the post to multiple categories.

Data Injected in Post Pages

You can access the detailed info of the categories of a post page via this.page.categoriesInfo, for instance:

categories:
  - sports/football
  - hobby

gives you:

;[
  {
    name: 'sports',
    permalink: '/categories/sports'
  },
  {
    name: 'football',
    permalink: '/categories/sports/football'
  },
  {
    name: 'hobby',
    permalink: '/categories/hobby'
  }
]

Nesting Category

It also support nesting categories:

categories:
  - sports/football

In this way, it will generate two pages: /categories/sports and /categories/sports/football and both of them will include this post.

Category Layout

Category pages will use the category layout or fallback to default layout.

You can access the category name in the layout component via this.page.category.

Pagination

By default we show at most 30 posts per page, but you can configure this globally using perPage option in saber-config.yml:

plugins:
  - resolve: saber-plugin-query-posts
    options:
      perPage: 6

It's also possible to configure this behavior for each page separately, in a page like pages/index.md:

---
injectAllPosts:
  perPage: 20
---

  }
}
