title: Wysiwyg editor for angular4
body: <p>Does someone knows a good free wysiwyg editor compatible with angular 4 ?</p>
  
  <p>Froala seems to be good but unfortunately it's not free.</p>
  
  <p>Maybe using angular 4 was not a good idea because it's hard to find a lot of basic things ...</p>
  
  <p>Thank you</p>
