DraftJS TO HTML

A library for converting DraftJS Editor content to plain HTML.

This is draft to HTML library I wrote for one of my projects. I am open-sourcing it so that others can also be benefitted from my work.

Installation

npm install draftjs-to-html

Usage

import { convertToRaw } from 'draft-js';
import draftToHtml from 'draftjs-to-html';

const rawContentState = convertToRaw(editorState.getCurrentContent());

const markup = draftToHtml(
  rawContentState, 
  hashtagConfig, 
  directional, 
  customEntityTransform
);

The function parameters are:

  1. contentState: Its instance of RawDraftContentState

  2. hashConfig: Its configuration object for hashtag, its required only if hashtags are used. If the object is not defined hashtags will be output as simple text in the markdown.

    hashConfig = {
      trigger: '#',
      separator: ' ',
    }
    

    Here trigger is character that marks starting of hashtag (default '#') and separator is character that separates characters (default ' '). These fields in hastag object are optional.

  3. directional: Boolean, if directional is true text is aligned according to bidi algorithm. This is also optional.

  4. customEntityTransform: Its function to render custom defined entities by user, its also optional.

    editorState is instance of DraftJS EditorState.

Following is the list of conversions it supports:

  1. Convert block types to corresponding HTML tags:
