Bubo Reader is a somewhat irrationally minimalist <acronym title="Really Simple Syndication">RSS</acronym> and <acronym title="JavaScript Object Notation">JSON</acronym> feed reader you can deploy on [Netlify](https://netlify.com) in a few steps or [Glitch](https://glitch.com) 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.

|
||||||
|
|
||||||
## Getting Started
|
## Getting Started
|
||||||
|
|
||||||
How to deploy Bubo Reader in a few easy steps with Netlify or Glitch:
|
- Clone or fork the repo and run `npm install` to install the dependencies.
|
||||||
|
- Update `feeds.json` to include categories and links to feeds you would like to see.
|
||||||
|
- Run `npm run build:bubo`
|
||||||
|
|
||||||
### Deploying to Glitch
|
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.
|
||||||
|
|
||||||
|
## Differences in Bubo 2.0
|
||||||
|
|
||||||
|
Version 2.0 has introduced some substantial changes for Bubo! While the static output remains endearingly spartan, the engine that builds it has changed a bit.
|
||||||
|
|
||||||
|
Hopefully all of these changes are in services of making this project more useful to others and encouraging outside contributions.
|
||||||
|
|
||||||
|
Changes of note:
|
||||||
|
|
||||||
|
- Bubo has been rewritten in [TypeScript](https://www.typescriptlang.org/). It's pretty slick! I anticipate the typing could be improved, but it's a start.
|
||||||
|
- You fill find an `.nvmrc` file in the root of this project. Learn more [about nvm](https://github.com/nvm-sh/nvm) if you're unfamiliar.
|
||||||
|
- The script will actually write your `index.html` file for you (Previously the build script simply ran `node src/index.js > output/index.html`). It makes a strong assumption that this file lives in the `public` folder.
|
||||||
|
- There is a somewhat sophisticated mechansim in-place for batching & throttling your requests, if needed.
|
||||||
|
## 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](https://mozilla.github.io/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 at `public/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 yout to batch and throttle your feed requests:
|
||||||
|
|
||||||
|
- `MAX_CONNECTIONS` dictates the maximium number of requests a batch can have going at once.
|
||||||
|
- `DELAY_MS` dictates the amount of de;ay time between each batch.
|
||||||
|
|
||||||
|
The default configuration is **no batching or throttling** beacuse `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:
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
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:
|
||||||
|
|
||||||
|
```javascript
|
||||||
|
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.
|
||||||
|

## Deploying to Netlify
|
||||||
|
|
||||||
The only difference between this branch and `master` is that it spins up a server using [Express](https://expressjs.com/) to serve your `./output/index.html` file on Glitch. Everything else is the same.
|
|
||||||
|
|
||||||
### Deploying to Netlify

|
||||||
|
|
||||||
- [Fork the repository](https://github.com/georgemandis/bubo-rss/fork)

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!

#### Using GitHub Actions
|
||||||
|
|
||||||
This approach is a little different and requires some modifications to the repository. Netlify started billing for [build minutes](https://www.netlify.com/pricing/faq/) very shortly after I published this project. Running `npm build` and downloading all of the RSS feeds took up a substantial number of this minutes, particulary if you had some kind of process pinging the webhook and trigger a build every 15 minutes or so.
|
Coming soon—there is an old branch that demonstrates this, but it needs to be revisisted in light of Bubo 2.0.
|
||||||
|
|
||||||
How is the The GitHub Action-based approach different? The same build process runs, but this time it's on GitHub's servers via the Action. It then **commits** the newly created file generated at `./output/index.html` back into the repository. Netlify still gets pinged when the repository is updated, but skips the `npm run build` step on their end, which significantly reduces the number of build minutes required.
|
#### Rolling Your Own
|
||||||
|
|
||||||
**Short Answer**: use the [`github-action-publishing`](https://github.com/georgemandis/bubo-rss/tree/github-action-publishing) branch for now if you'd prefer to use GitHub Actions to run your builds.
|
If you already have a server running Linux and some command-line experience it might be simpler to setup a [cron job](https://en.wikipedia.org/wiki/Cron).
|
||||||
|
|
||||||
The GitHub Action is setup to build and commit directly to the `master` branch, which is not the best practice. I'd suggest creating a separate branch to checkout and commit changes to in the Action. You could then specify that same branch as the one to checkout and publish on Netlify.
