This golang app provides the ability to:

• Login using a spotify account
• In slack, using the /spotify command in #shoreditch-tunes:
  • Add new tracks to the echo playlist: this will post to #shoreditch-tunes
  • Vote to skip the currently playing song, which starts a 10 second timer, after which if there are more votes to skip than keep the song will be skipped.
  • Vote to keep the currently playing song on
  • Check what's playing. This also posts to #shoreditch-tunes

1. Get yourself a spotify client ID and token. Go to https://developer.spotify.com, login with your spotify account and then head to dashboard, and click "create client ID"
2. Set up a slackbot in your apps, head to "oauth & permissions" and add the chat:write scope and the commands scope
3. Click "install to workspace", head to "Basic information", scroll down and copy the verification token. Whack this in a .env file and call it SLACK_VERIFICATION_TOKEN
4. Back in the slack manager, head to "Oauth and permissions", copy the "bot oauth token" and add that to your .env file as SLACK_BOT_TOKEN
5. Create a playlist in your chosen spotify account, then right click on the title, "share" and copy the Spotify URI. This should be of the format spotify:playlist:<id>. Drop off the first two sections and put the id in your env file as SPOTIFY_PLAYLIST_ID.
6. Run SPOTIFY_ID=<ID> SPOTIFY_SECRET=<SECRET> go run main.go, then go to the URL shown in the terminal window to handle oauth with spotify. For some bizarre reason godotenv doesn't work with the spotify library - i.e it can't find those variables in the env??
7. Install ngrok, add it to your path, then in a separate terminal window, run ngrok http 8080 and copy the url in "forwarding".
8. Head to "slash commands" back in the slack setup, add a new one for "/spotify" or similar and set the request url to the URL you just copied
9. Run a slash command (I do this in messages to myself) /spotify add <query> and it should give you back a list of songs!
