LBRY Comment Notifier

A small Elixir app polling the LBRY API for new comments via email.

Every hour, the application fetches all comments by going throught these three API methods: account_list, claim_list and comment_list. By fetching all accounts, the claims can be obtained; using those in turn, the comments can be fetched. Each comment is stored in the persistent storage and new comment are emailed. Since the APIs are paginated, the algorithm may not be the most efficient and perhaps LBRY can offer this functionality at a lower cost. For now though, paginated polling is good enough for a small channel.

Installation

This app was meant to run locally on a Raspberry Pi 3 with a configured lbry-sdk as the API (or a lbry-desktop which hosts an API too) and a mailcatcher as a SMTP server. So assuming the default configuration with an lbry-sdk running at http://localhost:5279 and a mailcatcher at http://0.0.0.0:1080 and smtp://0.0.0.0:1025, the app can be built annd run using:

mix deps.get

mix run --no-halt

MIX_ENV=prod mix distillery.release

cd _build/prod/rel/lbry_comment_notifier
nano config.toml                            # Check the configuration
bin/lbry_comment_notifier reload_config     # Update the configuration
bin/lbry_comment_notifier foreground

It uses the standard (distillery)[https://github.com/bitwalker/distillery] and (TOML)[https://github.com/bitwalker/toml-elixir] tooling so you can checkout config.toml in the release directory for the possible configurations.

Ideas

To make the application more palatable, the following ideas could be implemented:

[ ] Better email templates [ ] Switch persistent storage to ETS or Mnesia
