Collect news from your favourite Atom/RSS/JSON feeds and generate static web pages for easy browsing.

Status

The project has successfully been running since June 2021 without any major issues on my own sites. The only minor issues discovered so far has been with external feeds with poor behaviour.

Installation

go install github.com/lmas/feedloggr@latest

Usage

For a list of available flags and commands:

feedloggr help

You can create a new configuration file by running:

feedloggr example > .feedloggr.yml

You should then edit .feedloggr.yml and add your own feeds to it.

When you're done editing the configuration, you can test it and make sure there's no errors:

feedloggr test

If no errors are shown, you're good to go!

Now that you have a working configuration, it's time to start collect news from your feeds and export them to a web page:

feedloggr

When it's done you should be able to browse the newly generated page, found inside the output directory that was specified in the configuration file.
