feedi

feedi is a web feed reader with a minimal interface akin to a Mastodon or Twitter feed.

Features:


For background about the development of this project, see this blog post.

Documentation

Installation

feedi requires Python >= 3.9. If you don't have it installed already consider using pyenv or asdf.

To install feedi on a local environment:

git clone https://github.com/facundoolano/feedi.git
cd feedi
make

Then, to run the app:

make run

The application will be available at http://localhost:9988/.

Alternatively, see the instructions for running with Docker or in a non-local setup.

Basic usage

Adding sources

By default, your feed will be empty. You can load content in a number of ways:

When you first add a feed, the app will fetch its most recent articles, then it will check periodically for new content (every 30 minutes by default).

Browsing the feed

Reading articles

There are different ways to interact with a feed entry:

Deleting old articles

Entries get deleted automatically some days after their publication (defaulting to 7). Pinned and favorited entries are never deleted. Additionally, a minimum of entries (defaulting to 5) is kept for all sources, regardless of their publication date.

Advanced features

Bulk import/export feeds from csv and OPML files

make feed-load will load feeds from a local feeds.csv file. A sample file is included in the repo in case you want to see some content right away.

There's also a make feed-load-opml to import a list of RSS feeds from a feeds.opml file in the OPML format.

There are analogous make feed-dump and make feed-dump-opml targets to export feed data from the app.

Mastodon account setup

The Mastodon integration allows ingesting both the user home feed and the notification inbox as feeds. feedi first needs to be authorized to access the Mastodon account by navigating to Manage feeds > Mastodon login or to the url /auth/mastodon. After filling the instance name and grating access, feedi will redirect to the add feed form, where either mastodon or mastodon notifications feeds (or both) can be added.

Github notification feed

You can ingest the notifications from GitHub into feedi. To do so, navigate to your home feed at https://github.com/, open the page HTML source and search for an atom feed link. It should look something like:

  <link rel="alternate" type="application/atom+xml" title="ATOM" href="https://github.com/facundoolano/feedi/blob/main/facundoolano.private.atom?token=<TOKEN>" />

Copy the href url and use it to add a new RSS feed in feedi.

Goodreads home feed

You can ingest the notifications from Goodreads.com into feedi. To do so, navigate to your home feed at https://www.goodreads.com/, open the page HTML source and search for an atom feed link. It should look something like:

<link href='https://www.goodreads.com/home/index_rss/<ID>?key=<KEY>' rel='alternate' title='Goodreads' type='application/atom+xml'>

Copy the href url and use it to add a new RSS feed in feedi.

Reddit feeds

Reddit exposes public pages as RSS feeds by appending .rss to the URL, for example https://www.reddit.com/r/selfhosted.rss or www.reddit.com/user/someuser.rss.

Additionally, authenticated users have access to RSS feeds for private account pages: the front page, saved links, message inbox, etc. Links can be found here. feedi uses special purpose feed parsers both for reddit listing messages and links, and for the user inbox.

Kindle device support

The app allows to register a kindle email to send the cleaned up article HTML to it, yielding better results than the default Amazon Send to Kindle Chrome extension. This requires setting up SMTP credentials for sending email.

Steps to make it work with a basic gmail account:

  1. Register an google email account.
  2. Turn on 2-factor authentication for the account
  3. navigate to the app passwords settings and generate a password for the app (requires 2FA activated to work).
  4. Add SMTP settings to the app config:
FEEDI_EMAIL = "YOUR.EMAIL@gmail.com"
FEEDI_EMAIL_PASSWORD = "GENERATED APP PASSWORD"
FEEDI_EMAIL_SERVER = "smtp.gmail.com"
FEEDI_EMAIL_PORT = 587
  1. navigate to /auth/kindle or type 'kindle' in the searchbox, and enter the @kindle.com email for your device.
  2. Go to your Amazon Personal Document Settings and add your feedi email address to the approved document email list.

After this setup the "Send to Kindle" command will be available when browsing articles.

Feed parsing

The app works by periodically fetching items from different feed sources (RSS/Atom, Mastodon toots and notifications, custom scrapers) and adjusting them to an Entry db model which more or less matches what we expect to display in the front end.

RSS/Atom feeds

Most RSS feeds should be processed correctly by the default parser, but sometimes it's desirable to add customizations that cleanup or extend the data for a better look and feel. This can be done by subclassing feedi.parsers.rss.BaseParser. The is_compatible static method determines whether a given feed should be parsed with that specific class; the parse_* methods overrides the default logic for each field expected in the front end.

As an example, this parser for the lobste.rs link aggregator is adjusted to inline a summary of external link submissions and distinguish between the source article url and the lobste.rs discussion url:

class LobstersParser(BaseParser):
    def is_compatible(_feed_url, feed_data):
        return 'lobste.rs' in feed_data['feed'].get('link', '')

    def parse_content_short(self, entry):
        # A 'Comments' link is only present on external link submissions
        if 'Comments' in entry['summary']:
            url = self.parse_content_url(entry)
            return (self.fetch_meta(url, 'og:description') or
                    self.fetch_meta(url, 'description'))
        return entry['summary']

    def parse_entry_url(self, entry):
        # return the discussion url, which is different from entry['link']
        # for external links
        if 'Comments' in entry['summary']:
            soup = BeautifulSoup(entry['summary'], 'lxml')
            return soup.find("a", string="Comments")['href']
        return entry['link']

You can see several custom RSS parsers in this module.

Custom feeds

Other than RSS and Mastodon feeds, the app can ingest arbitrary sources with custom parsers. This is useful for scraping websites that don't provide feeds or consuming JSON APIs directly.

To add a custom parser, subclass feedi.parsers.custom.CustomParser. The is_compatible method determines wheter a given url should be parsed with that parser. The fetch method does the actual fetching and parsing of entries. See the feedi.parsers.custom module for some examples.

Once the parser is implemented, it will be used when a new feed of type "Custom" is added in the webapp with the expected url.

User management

The default app configuration assumes a single-user unauthenticated setup, but authentication can be enabled in case security is necessary, for example to deploy the app on the internet or to support multiple accounts.

To enable user authentication:

  1. Remove the DEFAULT_AUTH_USER setting from the configuration.
  2. If you already have a DB created, reset it with make db-reset. Or, alternatively, remove the default user with make user-del EMAIL=admin@admin.com. Note that this will also remove feeds and entries associated to it in the DB.
  3. You can create new users by running make user-add EMAIL=some@email.address. The command will prompt for a password.

Note that there's no open user registration functionality exposed to the front end, but it should be straightforward to add it if you need it. Check the auth module and the flask-login documentation for details.

Running with Docker

Get the image from github packages:

docker pull ghcr.io/facundoolano/feedi:latest

Create a volume for persisting the db data:

docker volume create feedidb

Load the default feeds into the default admin user:

docker run -v feedidb:/app/instance ghcr.io/facundoolano/feedi flask --app feedi/app.py feed load feeds.csv admin@admin.com
docker run -v feedidb:/app/instance ghcr.io/facundoolano/feedi flask --app feedi/app.py feed sync

Run in development mode:

docker run -p 9988:9988 -v feedidb:/app/instance ghcr.io/facundoolano/feedi

To run in production mode, a config file with at least a secret key is expected:

echo "SECRET_KEY = '$(python -c 'import secrets; print(secrets.token_hex())')'" >> production.py
docker run -p 9988:9988 -e FLASK_ENV=production -v feedidb:/app/instance -v $(pwd)/production.py:/app/feedi/config/production.py ghcr.io/facundoolano/feedi

To enable authentication, add DEFAULT_AUTH_USER=None to that production config file.

Non-local setup

You can refer to the Flask documentation for a instructions on how to deploy feedi to a non-local environment. The setup script included in the repository shows an example setup for a Debian server. You can run it remotely with ssh like make prod-install SSH=user@server.
