DraftJS: Export ContentState to HTML

This is a module for DraftJS that will export your editor content to semantic HTML.

It was extracted from React-RTE and placed into a separate module for more general use. Hopefully it can be helpful in your projects.

Installation

npm install --save draft-js-export-html

How to Use

import {stateToHTML} from 'draft-js-export-html';
let html = stateToHTML(contentState);

Options

You can optionally pass a second "options" argument to stateToHTML which should be an object with one or more of the following properties:

inlineStyles

You can define rendering options for inline styles. This applies to built-in inline styles (e.g. BOLD) or your own custom inline styles (e.g. RED). You can specify which element/tag name will be used (e.g. use <b> instead of <strong> for BOLD). You can add custom attributes (e.g. class="foo") or add some styling (e.g. color: red).

Example:

let options = {
  inlineStyles: {
    // Override default element (`strong`).
    BOLD: {element: 'b'},
    ITALIC: {
      // Add custom attributes. You can also use React-style `className`.
      attributes: {class: 'foo'},
      // Use camel-case. Units (`px`) will be added where necessary.
      style: {fontSize: 12}
    },
    // Use a custom inline style. Default element is `span`.
    RED: {style: {color: '#900'}},
  },
};
let html = stateToHTML(contentState, options);

blockRenderers

You can define a custom renderer for any block type. Pass a function that accepts block as an argument. You can return a string to render this block yourself, or return nothing (null or undefined) to defer to the default renderer.

Example:

let options = {
  blockRenderers: {
    atomic: (block) => {
      let data = block.getData();
      if (data.get('foo') === 'bar') {
        return '<div>' + escape(block.getText()) + '</div>';
      }
    },
  },
};
let html = stateToHTML(contentState, options);

blockStyleFn

You can define custom styles and attributes for your block, utilizing the underlying built-in rendering logic of the tags, but adding your own attributes or styles on top. The blockStyleFn option takes a block and returns an Object similar to inlineStyles of the following signature or null:

{
  attributes: {}
  style: {}
}

Example:

let options = {
  blockStyleFn(block) => {
    if (block.getData().get('color')) {
      return {
        style: {
          color: block.getData().get('color')
        }
      }
    }
  }
}
let html = stateToHTML(contentState, options);
