Usage

import { documentToHtmlString } from '@contentful/rich-text-html-renderer';

const document = {
  nodeType: 'document',
  content: [
    {
      nodeType: 'paragraph',
      content: [
        {
          nodeType: 'text',
          value: 'Hello world!',
          marks: [],
        },
      ],
    },
  ],
};

documentToHtmlString(document); // -> <p>Hello world!</p>

import { documentToHtmlString } from '@contentful/rich-text-html-renderer';

const document = {
  nodeType: 'document',
  content: [
    {
      nodeType: 'paragraph',
      content: [
        {
          nodeType: 'text',
          value: 'Hello',
          marks: [{ type: 'bold' }],
        },
        {
          nodeType: 'text',
          value: ' world!',
          marks: [{ type: 'italic' }],
        },
      ],
    },
  ],
};

documentToHtmlString(document); // -> <p><b>Hello</b><u> world!</u></p>

You can also pass custom renderers for both marks and nodes as an optional parameter like so:

import { BLOCKS, MARKS } from '@contentful/rich-text-types';
import { documentToHtmlString } from '@contentful/rich-text-html-renderer';

const document = {
  nodeType: 'document',
  data: {},
  content: [
    {
      nodeType: 'paragraph',
      data:{},
      content: [
        {
          nodeType: 'text',
          value: 'Hello',
          marks: [{ type: 'bold' }],
          data: {}
        },
        {
          nodeType: 'text',
          value: ' world!',
          marks: [{ type: 'italic' }]
          data: {}
        },
      ],
    },
  ]
};

const options = {
  renderMark: {
    [MARKS.BOLD]: text => `<custom-bold>${text}<custom-bold>`
  },
  renderNode: {
    [BLOCKS.PARAGRAPH]: (node, next) => `<custom-paragraph>${next(node.content)}</custom-paragraph>`
  }
}

documentToHtmlString(document, options);
// -> <custom-paragraph><custom-bold>Hello</custom-bold><u> world!</u></custom-paragraph>

Last, but not least, you can pass a custom rendering component for an embedded entry:

import { BLOCKS } from '@contentful/rich-text-types';
import { documentToHtmlString } from '@contentful/rich-text-html-renderer';

const document = {
  nodeType: 'document',
  data: {},
  content: [
    {
      nodeType: 'embedded-entry-block',
      data: {
        target: (...)Link<'Entry'>(...);
      },
    },
  ]
};

const options = {
  renderNode: {
    [BLOCKS.EMBEDDED_ENTRY]: (node) => `<custom-component>${customComponentRenderer(node)}</custom-component>`
  }
}

documentToHtmlString(document, options);
// -> <custom-component>(...)Link<'Entry'>(...)</custom-component>

The renderNode keys should be one of the following BLOCKS and INLINES properties as defined in @contentful/rich-text-types:

• BLOCKS

  • DOCUMENT
  • PARAGRAPH
  • HEADING_1
  • HEADING_2
  • HEADING_3

  • OL_LIST
  • LIST_ITEM
  • QUOTE
  • HR
  • EMBEDDED_ENTRY
  • EMBEDDED_ASSET
  • EMBEDDED_RESOURCE

• INLINES

  • EMBEDDED_ENTRY (this is different from the BLOCKS.EMBEDDED_ENTRY)
  • HYPERLINK
  • ENTRY_HYPERLINK
  • ASSET_HYPERLINK

The renderMark keys should be one of the following MARKS properties as defined in @contentful/rich-text-types:

• BOLD
• ITALIC
• UNDERLINE
• CODE
• SUPERSCRIPT
• SUBSCRIPT
