Is it possible to make such a chat?

Question

JavaScript

Recently I found such a design of the messenger:

And the following question arose. Is it possible to receive chats and develop such a messenger by collecting chats from at least several chat services? The question is solely for the purpose of self-education, I searched on google, did not find it, or searched incorrectly. Please give hints on how to arrange this, if possible. Preferably do everything using javascript, nodejs...

Answer 1

Possibly easy if the service has a public API. For example, telegram. For most other services, protocol reverse engineering will be required, which is already quite difficult.

Answer 2

Is it possible to receive chats?
I think it depends on the specific service. It is unlikely that someone will provide an API, you can simulate the work of a client application / browser and download correspondence, showing them in the desired design.
Everything is in your hands :) But why?

Answer 3

yes it is possible

Answer 4

There is a universal open source pidgin messenger.
It has plugins for steam-chat, skype, xmpp, icq and a bunch of other plugins .
Those. there is some possibility of integration.
At least all this is open source, which means you can get the necessary protocols from there yourself.
A desktop application on js can be done using Electron

Answer 5

Yes it is possible. Using streams and other benefits of Node.js
