editorjs-html

A utility to parse editorjs clean data to HTML.

Use it with plain Javascript/Typescript, React, Angular, Vue or any templating engine/framework of your choice.
Fast, Efficient and Lightweight.
Fully customizable to the core.
Supports basic editorjs blocks which are customizable as well.
Extend to parse your own blocks.

Whats' new in v4?

Complete Rewrite, latest dependencies with minimal API changes.
Redundant parseStrict() and validate() functions are removed.
Strict mode is configurable via options.
Console errors if parser functions for block is not avaiable. Strict Mode throws errors.
Code is more readable, modular. It would make it easier to contribute and track changes.
Type definitions directly fetched from Editor.js, so development becomes easier.
Unit Testing with Jest.

Parse Entire EditorJS Data Object

const edjsParser = edjsHTML();
const HTML = edjsParser.parse(editorjs_data);
// returns array of html strings per block
console.log(HTML);

Parse Entire EditorJS Data Object (Strict Mode)

const edjsParser = edjsHTML();
const HTML = edjsParser.parse(editorjs_data);
// returns an error
if (HTML instanceof Error) throw HTML;

// in case of success, returns an array of strings
console.log(HTML);

Parse Single Clean Data Block

const edjsParser = edjsHTML();
const blockHTML = edjsParser.parseBlock(editorjs_data_block);
// returns string of html for this block
console.log(blockHTML);

Strict Mode

const edjsParser = edjsHTML({}, { strict: true });
// returns the list of missing parser functions
const blockHTML = edjsParser.parse(editorjs_data);
console.log(blockHTML);

Extend For Custom Blocks

editorjs-html supports extending and overriding parser functions for blocks.

  // Example Custom or Unrecognised 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 plugins = {
  // The keyname must match with the type of block you want to parse with this funcion
  custom: customParser,
  // ... add more or overwrite
};

const edjsParser = edjsHTML(plugins);
