Social commeting template in Ionic?

I assume that this is a very common feature, but there is little introduction or template out there in the internet.

I want to, in UI, have a comment zone under each article, so that people can:

  1. post comments
  2. reply to others’ comments
  3. give “thumb up” to either comments or replies
  4. list the comments by the number of “thumb ups”

Any hint is appreciated!
