Nuxt Strapi Blocks Renderer

A fully customizable Nuxt 3 module for rendering text with the new Blocks rich text editor element from Strapi CMS.

The implementation is based on Strapi's Blocks React Renderer.

Installation

1. Install the Blocks renderer:

   npm install nuxt-strapi-blocks-renderer

2. Add the module to nuxt.config.{ts|js}:

   modules: ['nuxt-strapi-blocks-renderer']

Usage

To render text, use the StrapiBlocksText component:

<StrapiBlocksText :nodes="blockNodes" />

In this example, the blockNodes are taken from the JSON response which Strapi provides when using the Blocks rich text editor element:

<script setup lang="ts">
    import type { BlockNode } from '#strapi-blocks-renderer/types';
    import type { Restaurant } from '~/types';

    const route = useRoute();
    const { findOne } = useStrapi();

    // Fetch restaurants data from Strapi
    const response = await findOne<Restaurant>('restaurants', route.params.id);
    
    // Obtain blocks text nodes from description field
    const blockNodes: BlockNode[] = response.data.attributes.description;
</script>

<template>
    <!-- Render blocks text -->
    <StrapiBlocksText :nodes="blockNodes" />
</template>

To use the useStrapi composable, install the Strapi Nuxt module.

Advanced Usage

In situations where your project requires specific styling or behavior for certain HTML tags such as <a>, <p>, and others, you can override the default rendering components used by the Nuxt Strapi Blocks Renderer. This flexibility allows you to tailor the rendering to align with your project's unique design and functional needs.

Global Component Registration

First, ensure that your components are globally registered in your Nuxt app. This step is crucial for your custom components to be recognized and used by the renderer.

In your Nuxt configuration (nuxt.config.{js|ts}), add:

components: {
    dirs: [
        {
            path: '~/components',
        },
    ],
    global: true,
},

Customizing the Paragraph Tag

To customize the rendering of the paragraph (<p>) tag, you need to create a corresponding Vue component. The name of the component follows a predefined pattern: 'StrapiBlocksText' + [NodeName] + 'Node.vue'. To override the default paragraph tag, we create a file called StrapiBlocksTextParagraphNode.vue.

<!-- components/StrapiBlocksTextParagraphNode.vue -->
<template>
    <p class="my-custom-class-for-p">
        <slot />
    </p>
</template>

This component assigns a custom class my-custom-class-for-p to the paragraph tag, which can be styled as needed.

The prefix for the custom components can be adjusted in your nuxt.config.{js|ts}:

modules: ['nuxt-strapi-blocks-renderer'],
strapiBlocksRenderer: {
    prefix: 'MyCustomPrefix'
    blocksPrefix: 'MyCustomBlocksPrefix',
},

With this configuration, the StrapiBlocksText component becomes MyCustomPrefixStrapiBlocksText and the custom paragraph node component would be named MyCustomBlocksPrefixParagraphNode.

Other Custom Tags

You can apply similar customizations to all other HTML tags used by the renderer:

Custom heading tags (<h1>, <h2>, <h3>, etc.):

<!-- components/StrapiBlocksTextHeading1Node.vue -->
<template>
    <h1 class="my-custom-class-for-h1">
        <slot />
    </h1>
</template>

<!-- components/StrapiBlocksTextHeading2Node.vue -->
<template>
    <h2 class="my-custom-class-for-h2">
        <slot />
    </h2>
</template>

This pattern also extends to the h3, h4, h5 and h6 tags.

Custom list tags (<ol>, <ul> and <li>):

<!-- components/StrapiBlocksTextOrderedListNode.vue -->
<template>
    <ol class="my-custom-class-for-ol">
        <slot />
    </ol>
</template>

<!-- components/StrapiBlocksTextUnorderedListNode.vue -->
<template>
    <ul class="my-custom-class-for-ul">
        <slot />
    </ul>
</template>

<!-- components/StrapiBlocksTextListItemInlineNode.vue -->
<template>
    <li class="my-custom-class-for-li">
        <slot />
    </li>
</template>

Custom blockquote and code tags (<blockquote>, <pre>):

<!-- components/StrapiBlocksTextQuoteNode.vue -->
<template>
    <blockquote class="my-custom-class-for-blockquote">
        <slot />
    </blockquote>
</template>

<!-- components/StrapiBlocksTextCodeNode.vue -->
<template>
    <pre class="my-custom-class-for-pre"><slot /></pre>
</template>

Custom inline text nodes (<strong>, <em>, <u>, <del>, <code>):

<!-- components/StrapiBlocksTextBoldInlineNode.vue -->
<template>
    <strong class="my-custom-class-for-strong">
        <slot />
    </strong>
</template>

<!-- components/StrapiBlocksTextItalicInlineNode.vue -->
<template>
    <em class="my-custom-class-for-em">
        <slot />
    </em>
</template>

<!-- components/StrapiBlocksTextUnderlineInlineNode.vue -->
<template>
    <u class="my-custom-class-for-u">
        <slot />
    </u>
</template>

<!-- components/StrapiBlocksTextStrikethroughInlineNode.vue -->
<template>
    <del class="my-custom-class-for-del">
        <slot />
    </del>
</template>

<!-- components/StrapiBlocksTextCodeInlineNode.vue -->
<template>
    <code class="my-custom-class-for-code">
        <slot />
    </code>
</template>

Custom link tag (<a>):

<!-- components/StrapiBlocksTextLinkInlineNode.vue -->
<script setup lang="ts">
    const props = defineProps<{
        url: string;
    }>();
</script>

<template>
    <a :href="props.url" class="my-custom-class-for-a">
        <slot />
    </a>
</template>

When rendering a link tag, the url gets passed as the url component property.

Custom image tag (<img>):

<!-- components/StrapiBlocksTextImageNode.vue -->
<script setup lang="ts">
    const props = defineProps<{
        image: any;
    }>();
</script>

<template>
    <img
        class="my-custom-class-for-img"
        :src="props.image.url"
        :alt="props.image.alternativeText"
        :width="props.image.width"
        :height="props.image.height"
    >
</template>

When rendering an image tag, the image object gets passed as the image component property. You can also use different image components here, i.e. NuxtImg or others.
