Supported services

Last.fm and Spotify have an initial implementation.

In the future, I would like to add support for ListenBrainz and CSV/JSON files as well (#27).

Authentication

Before using any of the provided services, you need to create your own API application on said service and export your new API client ID and secret as environment variables:

Service	Creating your app	Environment variables
Last.fm	Create an account here	LASTFM_CLIENT_ID and LASTFM_CLIENT_SECRET
Spotify	Manage and create an app here	SPOTIFY_CLIENT_ID and SPOTIFY_CLIENT_SECRET

When this is done, continue with the following steps.

1. Run admirer login <service> to retrieve an authentication URL.
2. By visiting this URL, the service will ask confirmation and redirect back to a non existing URL https://admirer.test/....
3. Copy and paste the desired query parameter from the URL into the CLI input and press Enter.
4. If all goes well, you will retrieve confirmation that you have been logged in.

Note 1: after #23, API client IDs and secrets will be queried during login and stored along with other authentication secrets.

Note 2: #25 will add an internal HTTP server to retrieve the authentication callback automatically.

Use cases

Listing recently loved or added tracks

Using the list command, you can retrieve a list of your most recently loved or added tracks on said service.

Syncing recently loved tracks between services

Using the sync command, you can synchronise recently loved tracks from one service to another. For example to mark as loved on Last.fm the same tracks that were added to your library on Spotify, or vice versa.
