# Basic spotify API in golang
This API supports simple artist read operations for spotify data, as well as using a simple caching database and handling client authentication automatically.

## Setup
After compiling the binary, or when executing via `go run`, just be sure to set the following environment variables to enable access to Spotify's API
```
SPOTIFY_ID=<your spotify client ID>
SPOTIFY_TOKEN=<your spotify token>
```

Example execution using the linux command line:
`SPOTIFY_ID=myspotifyID SPOTIFY_TOKEN=myspotifytoken ./gomusic`

Alternatively you can use `go run` too:
`SPOTIFY_ID=myspotifyID SPOTIFY_TOKEN=myspotifytoken go run .`

## Testing
This application comes with a complete test suite, it can be run using the standard `go test` system
When running tests you are required to provide the same credentials as when running the server normally.

For example:
`SPOTIFY_ID=myspotifyID SPOTIFY_TOKEN=myspotifytoken go test .`

## Technical Choices
This project is built using the Gin framework, for easy and consistent request contexts, as well as easy to expand middleware support.
For database interactions it uses the gorm library, to allow for advanced SQL features and server agnostic support.

This API currently uses sqlite as the database for simplicity, but switching to postgres or mysql is easy without any loss of functionality or change in database calls.
