Github Issues Notifier 📢

A daemon process that listens for new issues in Github repositories and notifies about them via email.

I run this in a Raspberry Pi 4 🫐 and use it to monitor Open Source repos that I like to contribute to.

Prerequisites

• docker (but not really, you could also compile the binary)
• make (but not really, you can just check the contents of the Makefile and use docker directly)
• go 1.21+ (but not really, only if you decide not to use docker)

Installation

This is intended to be used as a Docker container, although it could also be compiled and run as a standalone Go binary using something like systemd.

1. Clone this repository

$ git clone https://github.com/yugarinn/github-issues-notifier

2. Change to the notifier folder and execute the run command

$ cd github-issues-notifier
$ make run

It is also possible to:

3. Check the logs:

$ make logs

4. Stop the service

$ make stop

Configuration

The notifier relies on a yml file to define which repositories it should listen to. This is an example configuration file:

listeners:
  - name: 'lila'
    repository: 'lichess-org/lila'
    email_to: 'address@mail.com'
    is_active: true
    filters:
      labels: 'good first issue'
      assignee: 'none'

  - name: 'doom'
    repository: 'doomemacs/doomemacs'
    email_to: 'address@mail.com'
    is_active: true
    filters:
      labels: 'good first issue,help wanted'

  - name: 'rails'
    repository: 'rails/rails'
    email_to: 'address@mail.com'
    is_active: true
    filters:
      labels: 'good first issue,help wanted'

Each listener is composed of:

• Its name.
• The repository it should listen to in the owner/repository format.
• The email to send the notification to.
• An active flag.
• A filters list.

Only the issues that match the defined filters in each listener are taken into account. Also, keep in mind that just label filters are implemented.

Environment variables

Since you need to bring your own SMTP server, the following variables MUST be defined in a .env file in the root folder of the project:

• SMTP_HOST
• SMTP_PORT
• SMTP_EMAIL_FROM
• SMTP_PASSWORD

The following variables are optional:

• WORKER_CRON_FREQUENCY defaults to "*/30 * * * *" (at every 30th minute)
• LISTENERS_FILE_PATH Where the configuration file defining the listeners is located. Defaults to "./listeners.yml".
• LISTENERS_DATABASE_PATH Where the database file (this uses bbolt under the hood) is located. This database is needed jsut to keep track of the already notified issues, nothing fancy really. Defaults to "./listener.db"
