Implement Spotify API

[spinks]

Need to implement a simple, no-account client verified, api to search for and select songs for a silent disco song request functionality. Plan is for a limited number (1 or 2) of songs to be selected per device.

Links for reference:

• spotify authorisation guide
• spotify general api guide

Can get device UUID using https://capacitor.ionicframework.com/docs/apis/device. Write song choice with UUID as key to one document on firebase

If we want to display their current song choice on the app this should be done via local storage, so as not to have many document reads due to the frequency of this ones updating.

Need to add song selection, display current song, push to firebase And annoyances with closing the keyboard

[spinks]

Still have annoyances with keyboard (dismiss on scroll and enter give a weird state where it can be reopened by pressing area where keyboard used to be.

May have issues with large amounts of Firestore reads for some reason, despite only implementing a set method, (look into).

Documentation needed on the readme

[spinks]

This is closed, but will keep open for an investigation into the seemingly high number of document reads on firebase
