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.

Installing

npm install draftjs-to-html

Using

import draftToHtml from 'draftjs-to-html';

const rawContentState = convertToRaw(editorState.getCurrentContent());
const markup = draftToHtml(contentState, 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 ' ').

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

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

Supported conversions

Following is the list of conversions it supports:

1. Convert block types to corresponding HTML tags:

	Block Type	HTML Tag
1	header-one	h1
2	header-two	h2
3	header-three	h3
4	header-four	h4
5	header-five	h5
6	header-six	h6
7	unordered-list-item	ul
8	ordered-list-item	ol
9	blockquote	blockquote
10	unstyled	p

It performs these additional changes to text of blocks: - replace blank space in beginning and end of block with   - replace \n with <br>\n - replace < with < - replace > with >

2. Converts ordered and unordered list blocks with depths to nested structure of <ul>, <ol> and <li>.

3. Converts inline styles BOLD, ITALIC, UNDERLINE, STRIKETHROUGH, CODE, SUPERSCRIPT, SUBSCRIPT to corresponding HTML tags: <strong>, <em>, <ins>, <code>, <sup>, <sub>.

4. Converts inline styles color, background-color, font-size, font-family to a span tag with inline style details: <span style="color:xyz;font-size:xx">. The inline styles should start with strings color or font-size like color-red, color-green or fontsize-12, fontsize-20.

5. Converts entity range of type link to anchor tag using entity data url for href: <a href="url">text</a>.

6. Converts entity range of type mention to anchor tag using entity data url for href and also adds class to it: <a href="url" class="wysiwyg-mention">text</a>.

7. Converts atomic entity image to image tag using entity data src for image source: <img src="src" />.

8. Converts embedded links to iFrames.

9. Converts hashtags to anchor tag: <a href="#tag" class="wysiwyg-hashtag">#tag</a>.

10. customEntityTransform can be used for transformation of a custom entity block to html.

11. Adding style property to block tag for block level styles like text-align: <p style="text-align: right">text</p>.

12. RTL, if directional function parameter is true, generated blocks have property dir = "auto" thus they get aligned according to bidi algorithm.
