Thanks @jarsbe for such good solution
Could you also a bit point me how to use it . Right now I tried to apply this linkifyEditorState on editor's change
onChange = (editorState) => this.setState({ editorState: linkifyEditorState(editorState) })
but I'm getting unexpected editor's behavior when type hyperlink e.g. 'https://gith.......', then cursor is moving indifferent places, and start typing in wrong place
sorry if my question is too noob. I'm just trying with Draft and all this system around it

I have the same problem and can't get a solution :((

Ditto for @jurStv's and @melnik88's comments.

@jarsbe yeah, selection state seems to be a problem. Are you or @danii1 having any issues?

It's too outdated, but I rebuild logic and it works fine https://gist.github.com/anders0l/7a2c2b9a59b1c66a85089c597984d916
