Get the list of missing parser functions

  const edjsParser = edjsHTML();
  // returns the list of missing parser functions
  const blockHTML = edjsParser.validate(editorjs_data);

Extend For Custom Blocks

editorjs-html supports extending its functionality to render custom editorjs blocks. Moroever, You can even override these basic supported blocks.

• The edjsHTML() accepts an optional object that would allow you to extend its functionality.

• The name of the function must match with editor-js custom block type.

  // Your custom editorjs generated block
  {
    type: "custom",
    data: {
      text: "Hello World"
    }
 }

  // Parse this block in editorjs-html
  function customParser(block){
    return `<custom-tag> ${block.data.text} </custom-tag>`;
  }

  const edjsParser =  edjsHTML({custom: customParser});

[Update] From v2.0.0 onwards, the parser functions recieves full block instead of just data property of the block. Read releases for more information.
