OpenTelemetry

We use OpenTelemetry to provide observability into Listory API.

Traces will be sent to the specified endpoint.

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

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.
