Simple function to turn a Draft.js RawDraftContentBlock into a marked-up string.
$ npm install --save backdraft-js
var backdraft = require('backdraft-js');
var rawDraftContentBlock = Draft.convertToRaw(contentState);
var markup = {
'BOLD': ['<strong>', '</strong>'],
'ITALIC': ['<em>', '</em>']
};
var markedUpBlocks = backdraft(rawDraftContentBlock, markup);
markup
is an object, the key should be the DraftJS "style" identifier and the
value should be an array: the first item will be appended to the output to
"open" the style and the second tag will be appended to "close" the style. See
"Usage" above for a simple example.
