playlistsyncionic's Introduction

PlaylistSync

App overview

Purpose
- Give users the ability to manage their Youtube and Spotify playlists in a single location, especially in the case where users want to keep playlists stored in both places synchronized with each other
What it will look like
- Make account with email and password (or G-Suite, or perhaps facebook)
  - Log in with spotify and youtube
- The "Now Playing" view
  - Pick Spotify or Youtube as the platform you're streaming from
    - Show what is currently playing
  - Pick which playlists you want to add to for Spotify and Youtube (or save, add to favorites, etc.).
    - Selections will persist between songs and sessions.
  - A button to add song to both playlists
    - automatically saves and adds to the primary platform, then searches the secondary and lets you choose which matches.
  - If there are no matches, it will go into a list storing any songs that aren't synchronized between the two playlists
Technical implementation details
- OAuth 2.0 (store secret keys securely on the server/cloud)
  - Be sure to hash and salt the passwords (find a library for all your auth stuff)
- How to get "Now playing" information
  - Get information from Spotify
    - Spotify doesn't have event listening/publishing or Long polling (shame!)
    - No choice but to poll the crap out of their service to keep up to date with what's playing.
    - keep it to every 5 seconds for right now
  - Get information from the phone
    - iOS has an API that exposes the music player
    - ionic framework has a way of accessing it as well: check "Music Controls" in ionic-native, aka cordova-music-controls-plugin
    - apple developer program costs $99, and you need that to post to the app store.
      - But, you can have it run on only your own phone
