EH Forwarder Bot (EFB) is an extensible chat tunneling framework written in Python 3. GitHub.
EFB is mainly designed for gathering messages from many other platforms to the one platform, but also designed with other types of tunneling in mind. In this article, I’d like to introduce how EFB works now, and how to design channels for group chat tunneling with utilizing available channels in EFB. Here “group chat tunneling” means synchronizing messages across several groups in different platforms.
