Exclude Nodes

Add nodes to be excluded from the conversion

ContentfulConverter.configure do |config|
  config.forbidden_nodes = ['table', 'script', 'iframe']
end

<a>

• HTML hyperlinks with full URL e.g: (<a href="https://google.com"></a>), will be converted into URL hyperlinks

  {
    nodeType: 'paragraph',
    data: {},
    content: [
      {
        nodeType: 'hyperlink',
        data: {
          uri: 'https://google.com'
        },
        content: [
          {
            marks: [],
            value: 'click me',
            nodeType: 'text',
            data: {}
          }
        ]
      }
    ]
  }

• HTML hyperlinks without a scheme e.g: (<a href="/about_us/contact">about us</a>), will be converted into ENTRY hyperlinks, with the href value as an ID

  {
    nodeType: "paragraph",
    data: {},
    content: [
      {
        nodeType: "entry-hyperlink",
        data: {
          target: {
            sys: {
              id: "/about_us/contact",
              type: "Link",
              linkType: "Entry"
            }
          }
        },
        content: [
          {
            data: {},
            marks: [],
            value: "about us",
            nodeType: "text"
          }
        ]
      }
    ]
  }

• HTML hyperlinks without a scheme but with an extension e.g: (<a href="file.docx">file</a>), will be converted into ASSET hyperlinks, with the href value as an ID.

  {
    nodeType: "paragraph",
    data: {},
    content: [
      {
        nodeType: "asset-hyperlink",
        data: {
          target: {
            sys: {
              id: "file.docx",
              type: "Link",
              linkType: "Entry"
            }
          }
        },
        content: [
          {
            data: {},
            marks: [],
            value: "file",
            nodeType: "text"
          }
        ]
      }
    ]
  }

<embed /> AND <img />

If you want to add an embedded entry block, you need to create an <embed> element in HTML with src and type attributes, for ID and entry type. Images will be converted into embedded-asset-blocks by default and the src will be used as an ID.

• Embedded Entry block: <embed src="id_of_your_entry_123" type="entry"/>

    {
      data: {
        target: {
          sys: {
            id: "id_of_your_entry_123",
            type: "Link",
            linkType: "Entry"
          }
        }
      },
      content: [],
      nodeType: "embedded-entry-block"
    }

• Embedded Asset block: <embed src="id_of_your_entry_123" type="asset"/> Images: <img src='id_of_your_entry_123' />

    {
      data: {
        target: {
          sys: {
            id: "id_of_your_entry_123",
            type: "Link",
            linkType: "Asset"
          }
        }
      },
      content: [],
      nodeType: "embedded-asset-block"
    }
