block-content-to-vue v0.1.0

block-content-to-vue

Dynamically render Vue.js components from Sanity.

Installation

npm i --save block-content-to-vue

Import as module

import BlockContent from 'block-content-to-vue';

Use via cdn

Include the script file, then install the component with Vue.use(BlockContent); e.g.:

<script src="https://cdn.jsdelivr.net/npm/vue"></script>
<script src="https://cdn.jsdelivr.net/npm/block-content-to-vue"></script>
<script>
  Vue.use(BlockContent);
</script>

Usage

The component requires the props blocks and serializer.

<block-content :blocks="blocks" :serializer="serializer" />

blocks must be an array of content blocks from a Sanity query response e.g.:

[
  {
    _id: 12345, // required
    _type: 'heading-block',
    heading: 'The heading!',
    subtitle: 'The subtitle'
  },
  {
    _id: 12346, // required
    _type: 'two-column-block',
    leftColumn: 'Left column content',
    rightColumn: 'Right column content'
  }
]

serializer is an object describing the components you want to render based on the Sanity block's _type value. For now the serializer supports all custom types you define yourself in the schema, and the types span, em, underline and strike-through. The regular types like span receive the prop fields with all it's properties inside.

import Heading from '@/components/Heading.vue';
import TwoColumn from '@/components/TwoColumn.vue';
import Span from '@/components/Span.vue';
import Underline from '@/components/Underline.vue';

const serializer = {
  types: {
    'heading-block': Heading,
    'two-column-block': TwoColumn,
    'span': Span,
    'underline': Underline,
  }
}

The block-content-to-vue component will automatically make the properties of each block available as props in your component.

Let's have a look at the Heading component.

<template>
  <div>
    <h1>{{heading}}</h1>
    <p>{{subtitle}}</p>
  </div>
</template>

<script>
export default {
  name: "Heading",
  props: {
    heading: String,
    subtitle: String,
  },
};
</script>

We can now define the props our component will receive, and we can type-check each of them. We can also use internal state and all the other good stuff from a regular Vue.js component.

Implementation example

<template>
  <div id="app">
    <BlockContent :blocks="post['contentBlock']" :serializer="serializer" />
  </div>
</template>

<script>
import sanity from '@/sanity';
import BlockContent from "block-content-to-vue";

import Heading from "./components/heading.vue";
import Button from './components/button.vue'

const query = `*[_type == "post"] {
  _id,
  contentBlock
}
`

const serializer = {
  'heading': Heading,
  'button': Button,
}

export default {
  name: "App",
  components: { BlockContent },
  data() {
    return {
      post: {},
      serializer,
    };
  },
  created () {
    this.fetchData();
  },
  methods: {
    fetchData() {
      sanity.fetch(query).then(posts => {
        this.post = posts[0]
      });
    }
  }
};
</script>
