Update 13/01/23: Echo now supports Mastodon and webhooks as well as Micro.blog. Check out the website for more details.
Echo is a node script to post new items from an RSS feed to Micro.blog
Micro.blog already supports importing RSS feeds and handles it very well but
I'm a control freak I wanted a bit more control over the formatting as well as assigning categories on import.
Echo takes a config of RSS feeds as well as some formatting functions for items and posts them to Micro.blog. I run mine every 15 minutes but you could set it up to run whenever you want. The only requirements are
npm and a server to run it on (or you could run it on your computer and manually run it as and when).
