Bubo Reader is a hyper-minimalist feed reader (RSS, Atom, JSON) you can deploy on your own server, Netlify in a few steps or Glitch in even fewer steps! The goal of the project is to generate a webpage that shows a list of links from a collection of feeds organized by category and website. That's it.
It is named after this silly robot owl from Clash of the Titans (1981).
You can read more about this project on my blog:
- Introducing Bubo RSS: An Absurdly Minimalist RSS Feed Reader.
- Publishing Bubos RSS to Netlify with GitHub Actions
- Clone or fork the repo and run
npm installto install the dependencies. - Update
feeds.jsonto include categories and links to feeds you would like to see. - Run
npm run build:bubo
That's it! You should now have a static page with links to the latest content from your feeds in the public folder, ready to serve.
Anatomy of Bubo Reader
The static pieces:
conf/feeds.json- a JSON file containing your feed URLS separated into categories.config/template.html- a Nunjucks template that lets you change how the feeds are displayed. This can be changed to anything else you like— see below.public/style.css- a CSS file to stylize your feed output.public/index.html- The HTML file that gets automatically generated when Bubo is run.
The engine:
src/index.ts- The primary script you run when you want to build a new version of Bubo. It will automatically fetch the latest content from your feeds and build a new static file atpublic/index.html.src/renderer.ts— The renderer that loads Nunjucks, the template and understands how to process the incoming feed data. Prefer something else? This is the place to change it!src/utilities.ts— A variety of parsing and normalization utilities for Bubo, hidden away to try and keep things clean.
Throttling
In the main index.ts file you will find two values that allow you to batch and throttle your feed requests:
MAX_CONNECTIONSdictates the maximum number of requests a batch can have going at once.DELAY_MSdictates the amount of delay time between each batch.
The default configuration is no batching or throttling because MAX_CONNECTIONS is set to Infinity. If you wanted to change Bubo to only fetch one feed at a time every second you could set these values to:
const MAX_CONNECTIONS = 1;
const DELAY_MS = 1000;If you wanted to limit things to 10 simultaneous requests every 2.5 seconds you could set it like so:
const MAX_CONNECTIONS = 10;
const DELAY_MS = 2500;In practice, I've never really run into an issue leaving MAX_CONNECTIONS set to Infinity but this feels like a sensible safeguard to design.
Getting Started
The quickest way is to remix the project on Glitch: https://glitch.com/edit/#!/bubo-rss
There is also a glitch branch on this repo if you'd prefer to start there.
Just change some feeds in ./config/feeds.json file and you're set! If you'd like to modify the style or the template you can changed ./public/style.css file or the ./config/template.html file respectively.
- Fork the repository
- From your forked repository edit
config/feeds.jsonto manage your feeds and categories - Create a new site on Netlify from GitHub
The deploy settings should automatically import from the netlify.toml file. All you'll need to do is confirm and you're ready to go!
To keep your feeds up to date you'll want to setup a Build Hook for your Netlify site and use another service to ping it every so often to trigger a rebuild. I'd suggest looking into:
If you already have a server running Linux and some command-line experience it might be simpler to setup a cron job.
