RSS to ICS

Intro

Python script written in Flask to generate iCalendar (ICS) from RSS/Atom feeds. This should work as a serverless function.

Tested against my blog feed and several RSS feeds generated by RSSHub.

For whatever reason, it does not work for offcial RSSHub instance (rsshub.app) due to either official instance security configuration or a bug introduced between legacy branch (which I test against on my own instance) and latest master commit.

Usage

Let's say the instance is running at rss2ics.vercel.app, the RSS feed is example.com/feed, you can generate ics via rss2ics.vercel.app/?url=example.com/feed.

Install

IMO there is nothing to talk about. Just clone the repo and install the requirements to run it locally, or simply run commands like vercel to deploy it on platforms that support Python (serverless) functions.

Test

You can run the test suite via the following command:

# Setup virtualenv
virtualenv .venv
source ./.venv/bin/activate
# Install packages
pip install requirements-dev.txt
# Make sure to use module if you have pytest installed system-wide
# otherwise they would conflict and complain forever
python -m pytest tests/test_api.py

Maybe I would add more rules soon™, but for now it's nothing and only serve for my exploration of pytest.

Todo

Setup pytest and coverage for fun (WIP)
Add (better) Atom support
Use feed.title for ICS filename (not sure why it's None...)
