This is a demo project used to practice and experiment with technologies while using a fun domain, music. It's 100% dependent on connectivity to Spotify's API and does have any persistence.

The topics that you can find on this repo are Spring Security, OAuth2 and OIDC, Keycloak, Spring Webflux, Hexagonal Architecture, Reactive caching with Redis and containerization.

The app has two layers of authentication. First it uses Keycloak as and identity provider but once you log in you need additional authentication with Spotify. The reason behind this is that, besides experimenting with Keycloak and OAuth2, I can host the application online without it being publicly accessible. This way I don't have to deal with regulations. What regulations? Well, think about how many cookie banners you have to close during the day...

This repo is only one piece in the tech stack. It is built automatically using a Tekton pipeline and deployed using a gitops approach with ArgoCD into an Istio service mesh. It also has a basic front built in Vue.js.

Want to see what I mean with all that? Take a look at the videos.

If you want to experiment with this repo you need to go to Spotify Developer Dashboard and create a Spotify application that would provide you with a client id and a client secret.

At the moment music discoverabilty is the main feature.

Here are a some videos to showcase the tech stack and the development workflow.
