Telegram web version of group chat. What options?

Question

Chats

I want to make a web version of one group chat in Telegram. Required features:

1. View the last 100 chat log messages
   
2. Quick registration (possible through loginza or analogues) without the need to register in Telegram
   
3. Sending messages to a group chat
   

I did not find any existing implementations of such a function. What options are there? I would like something more or less ready, so that it remains only to finish the design.

You can take this post as a basis and complete it to a group post.
