Heavy Metal Notifier

Do you often miss out on the latest heavy metal album releases from your favorite bands due to a busy schedule? If so, we have the perfect solution for you! Our project will email you every time there are new heavy metal album releases.

The application works by creating a calendar from Wikipedia heavy metal releases page that lists all the heavy metal album releases throughout the year. It is consulted every day at 1am local time zone. If there are any new releases, an email containing a list of the releases will be sent to all confirmed users.

Run Locally

Clone the project.

  git clone https://github.com/reaper47/heavy-metal-notifier.git

Go to the project directory.

  cd heavy-metal-notifier

Build the project.

  task build

Copy the config.json file next to the executable and edit the variables. Ensure to rename the config.example.json file to config.json.

cp ./deploy/config.example.json ./bin/config.json

Start the server.

  ./bin/metal serve

Configuration File

The configuration file sets important variables for the application. Let's go over each of them.

Then, open config.json to edit the following variables:

• email.from: The administrator's email address
• email.sendGridAPIKey: Your SendGrid API key. The free tier should be sufficient for your needs.
• email.maxNumberUsers: The maximum number of users you can have. The number depends on your SendGrid plan. The free plan can send a maximum of 100 emails daily.
• port: The port the app will be served through.
• url: The website the app is served on. This URL is used in the emails.

Deployment

The project can currently be self-hosted using Docker or a service.

Docker

A Docker image called reaper99/heavy-metal is produced on every release.

Using Docker

You first have to fetch it.

docker pull reaper99/heavy-metal:latest

Then, run the image. You must pass your config.json file to the container.

docker run -v path/to/config.json:/app/config.json -p [host port]:[port specified in config.json] -d reaper99/heavy-metal:latest

Using Docker Compose

You can use Docker Compose to run the container. First, you need to modify the ports and the path to your local config.json in the compose.yaml.

Then, start the application.

docker-compose up -d

Access the app through your browser at http://localhost:[host port]. If you are using Windows and you intend to access the app on other devices within your home network, please ensure to Allow the connection of the Docker Desktop Backend inbound Windows Defender Firewall rule.

Service

First download and extract the latest release.

Then, copy the config.json file next to the executable and edit the variables.

Next, copy the service example file and edit the variables to run the app automatically on boot.

sudo cp ./deploy/metal-releases.service /etc/systemd/system/ 

Finally, start the service on boot.

sudo systemctl start heavy-metal-notifier.service
sudo systemctl enable heavy-metal-notifier.service

Sponsors

I am grateful for any support that helps me continue to develop this project. Your sponsorship will help me pay for the SendGrid paid plan to increase the limit of users. The free plan currently used allows sending a maximum of 100 emails per day. This means the application can have a maximum of 100 users because one email per user is sent whenever there are new heavy metal album releases.

You can sponsor me on GitHub Sponsors or Buy Me a Coffee.

Your support is greatly appreciated!
