drafty.js

Basic parser and formatter for very simple text markup. Mostly targeted at mobile use cases similar to Telegram, WhatsApp, and FB Messenger.

Supports conversion of user keyboard input to formatted text:

  • *abc* → abc
  • _abc_ → abc
  • ~abc~ → abc
  • `abc` → abc
Also supports forms and buttons. Nested formatting is supported, e.g. *abc _def_* -> abc def URLs, @mentions, and #hashtags are extracted and converted into links. Forms and buttons can be added procedurally. JSON data representation is inspired by Draft.js raw formatting.
