CLI - Persistent Config

Description

An example to show how an obtained access and refresh token can be stored persistently and re-used across application restarts. This results in fewer requests to spotifys authentication endpoints and a faster experience for the user. The example uses PKCE in combination with the PKCEAuthenticator, which automatically refreshes expired tokens.

The access and refresh token is saved in a credentials.json file of the current working directory.

Run it

Before running it, make sure you created an app in your spotify dashboard and https://localhost:5543 is a redirect uri of it.

# Assumes linux and current working directory is the cloned repository
cd SpotifyAPI.Web.Examples/Example.CLI.PersistentConfig
dotnet restore

SPOTIFY_CLIENT_ID=YourClientId dotnet run
# A browser window should appear
# Restarting the process should NOT open a new authentication window
# Instead, the local `crendentials.json` file is used
SPOTIFY_CLIENT_ID=YourClientId dotnet run
