Feed Master

Feed-Master is a service that aggregates and publishes RSS feeds. It can pull multiple feeds from different sources and publish them to a single feed. The service normalizing all the feeds to make sure the combined feed is valid, compatible with podcast clients and compatible with RSS 2.0 specification.

In addition to making RSS feeds, Feed-Master can also publish updates to both twitter and telegram. In case of telegram the actual mp3 audio file is published too. In case of twitter the mp3 audio file is published as a tweet with a link to the original audio file and with the episode info, like title and/or description.

Feed-Master supports extracting audio from youtube channels and use it to make the final feed. The service uses yt-dlp to pull videos and ffmpeg for audio extraction. In this mode feed-master serves the audio files in addition to the generated RSS feed.

Single-feed configuration

For a very simple configuration, command-line only configuration is available. In this case only a single sopurce feed is allowed and yt processing is disabled. The command-line configuration is the following:

Name of the channel or numeric ChatID could be used, here are the instructions on obtaining the ChatID. To be able to post messages to the channel, bot must be added as administrator with Post permission.

All this command-line mode is good for - process a single feed, send a telegram message and send a tweet on each new item.

Notifications

In both configuration modes, user can specify a list of telegram and twitter accounts to be notified.

API

See requests.http

public endpoints

• GET /rss/{name} - returns feed-set for given feed name
• GET /list - returns list of feed-sets (json)
• GET /image/{name} - returns image for given feed name
• GET /feed/{name}/sources - returns list of sources for given feed name

Web UI

Telegram notifications details

By default, (with only TELEGRAM_TOKEN provided) Telegram notifications will be sent using standard Bot API which has a limit of 50Mb for audio file upload.

You can provide TELEGRAM_API_ID and TELEGRAM_API_HASH (from here) to telegram-bot-api service in docker-compose.yml and uncomment TELEGRAM_SERVER for feed-master, then it would use the local bot api server to raise audio file upload limit from 50Mb to 2000Mb.

To use local telegram bot api server, use docker-compose up -d command instead of docker-compose up -d feed-master.
