Besides Ace features, <juicy-ace-editor> does:

  • provide extremely clean and easy way to embed it (see Usage)
  • observe DOM changes:
    • Update your code by just updating Element's text content
    • Change Editor's setting by changing DOM attributes
  • Compatible with Shadow DOM v0 and v1
  • Custom Elements v1 (more)

You can still fiddle with Ace editor programmatically using <juicy-ace-editor>.editor.

$ bower install juicy-ace-editor --save

Web Components v0 vs v1

Currently, this element supports both Shadow DOM v1 and v0, but only Custom Elements v1. If your environment uses Custom Elements v0 only, we strongly recommend to use lightweight v0 to v1 polyfill

bower install --save document-register-element
