El Monitorro is a telegram bot for reading RSS, Atom and JSON feeds. It’s written in Rust.

It has a landing site generated from its Readme and Changelog

Key features:

• High performance.

  All processing is done with Fang

• Filters - users can provide key words he wants to subscribe to

• Templates - users can set a format of messages

  Currently, it’s implemented using handlebars. And UX can be improved

A couple of channels created with this bot:

• https://t.me/emacs_posts - Emacs News and Posts
• https://t.me/metacritic_tv - Latest Tv Show Metascores on Metacritic

The libraries I wrote for this project:

• Fang
• Frankenstein

Potential features / improvements

• Limit the number of superfast feeds

• Instead of syncing every feed periodically sync the earliest feeds.

• Use handlebars directly for templates

  UX for templates can be improved

• Allow users to set their bot token
