Listory

Login with Spotify and Listory will save all tracks you listen to.

The listens report shows how many songs you have listened to during the last month (and all months prior to that).
Want to know which song you heard on your drive to work last tuesday? Now you can!	Find out what genres (or artists, albums, songs) you listen to the most!

Installation

Creating the Spotify App

To connect to the Spotify API, you need to create a new App on the Spotify Developer Dashboard.

Once the App is created, open the App Overview and click on the "Edit Settings" button. A new modal should open. In this modal, you need to add a Redirect URI, so that the login with Spotify actually works. This URL depends on where you want to host your Listory installation, see also APP_URL under Configuration / Application. The Redirect URI should be $APP_URL/api/v1/auth/spotify/callback. For the local example URL which is used in development, this would be http://localhost:3000/api/v1/auth/spotify/callback. If you have your own domain where you want to host Listory, this is probably something like https://listory.your-name.com/api/v1/auth/spotify/callback.

You can add multiple Redirect URIs and all will work.

Keep the tab open, as you will need the Client ID and Client Secret in the next step.

Deployment

Listory currently supports two deployment mechanisms: docker compose and Kubernetes Helm Chart.

docker compose

There are two docker compose files in the repository, for a production deployment, you want to use docker-compose.prod.yml.

You can copy this file to your server or whereever you want to run Listory. You will also need to copy the .env.sample file next to the docker-compose.prod.yml file and rename it to .env.

Open the .env file in an editor and put in the Spotify App Client ID and Client Secret.

Now you can configure Listory how you like by changing the environment of the listory service in the docker compose file, or by adding new values in the .env file. For a list of all available options, see section Configuration.

If you deploy Listory on the public internet, I recommend you to add a reverse proxy like Traefik, which you can configure to automatically add TLS certificates (putting the S into HTTPS).

Once you have set everything up, you can run this command to start Listory:

docker compose up --daemon --file docker-compose.prod.yml

This will start Listory in the background. Checkout the docker compose documentation, to learn how you can work with the containers, for example to restart them or to read the logs.

Helm Chart

We publish a Kubernetes Helm Chart that installs Listory into a Kubernetes cluster.

I have not yet setup publishing to an actual Chart Registry, so if you would like to use the chart, create an issue and I will set this up properly.

You can find the source code for the Helm Chart under [charts/listory](./charts/listory/).

Configuration

All configuration must be set as environment variables. Default values are added in bold, values that are required are marked with Required.

Application

• PORT: 3000: Port the webserver will listen on.
• APP_URL: http://localhost:3000: Public URL of the Application, is used to generate Links.

Authentication

• JWT_SECRET: Required, used to sign the JWTs.
• JWT_ALGORITHM: HS256: Algorithm used to sign the JWTs. One of HS256, HS384, HS512
• JWT_EXPIRATION_TIME: 1d: Lifetime of signed JWTs. Accepts strings like 1d, 2h, 15m.

Spotify

• SPOTIFY_CLIENT_ID: Required, Spotify App Client ID
• SPOTIFY_CLIENT_SECRET: Required, Spotify App Client Secret
• SPOTIFY_FETCH_INTERVAL_SEC: 60: Interval for fetching recently listened tracks from Spotify.
• SPOTIFY_UPDATE_INTERVAL_SEC: 60: Interval for updating previously imported music library entities (artist, album, track). Raise this number if you often hit the Spotify API Ratelimit.
• SPOTIFY_WEB_API_URL: https://api.spotify.com/: Spotify WEB API Endpoint.
• SPOTIFY_AUTH_API_URL: https://accounts.spotify.com/: Spotify Authentication API Endpoint.
• SPOTIFY_USER_FILTER: "": If set, only allow Spotify users with these ids to access the app. If empty, allow all users to access the app. Seperate ids with , eg.: 231421323123,other_id.

Database

• DB_HOST: Required, Database host
• DB_USERNAME: Required, Database username
• DB_PASSWORD: Required, Database password
• DB_DATABASE: Required, Database database
• DB_POOL_MAX: 50, max concurrent database connections

Sentry

You can use Sentry to automatically detect and report any exceptions thrown.

• SENTRY_ENABLED: false, Set to true to enable Sentry.
• SENTRY_DSN: Required, but only if SENTRY_ENABLED is true. The DSN for your Sentry project.

OpenTelemetry

We use OpenTelemetry to provide observability into Listory API.

The metrics will be exposed on a seperate port at :9464/metrics. Make sure that this endpoint is not publicly available in your deployment.

Traces will be sent to the specified endpoint.

To use observability tools locally, check out docker-compose setup in observability/.

• OTEL_METRICS_ENABLED: false, Set to true to activate metrics.
• OTEL_TRACES_ENABLED: false, Set to true to activate traces.
• OTEL_EXPORTER_OTLP_ENDPOINT: Required, but only if OTEL_TRACES_ENABLED is true. The endpoint that traces are sent to, see OpenTelemetry docs
• OTEL_EXPORTER_PROMETHEUS_PORT: 9464, Set to configure non-standard port for Prometheus metrics

Development

Configure Spotify API Access

Copy the file .env.sample to .env and add your Spotify API Key.

Starting the application

We use docker compose to provide a full local development environment.

$ docker compose up

You can now access the frontend at http://localhost:3000 and the API at http://localhost:3000/api.

Frontend and API will automatically reload on any code changes.

REPL Console

You can start the REPL console by starting the normal environment, and then running:

$ docker compose run console

Observability

If you want to start the observability suite (Metrics & Tracing) locally, you can use the observability docker compose profile:

$ docker compose --profile observability up

Grafana is then available at http://localhost:2345 and all sources are preconfigured.

Test

# unit tests
$ npm run test

# e2e tests
