walt-grover

Automatically update Slack status with current Spotify track.

Spotify Authentication

In order to access the Spotify API you must generate a proper OAuth token following the Spotify Authorizataion Guide.

This repository contains a simple callback script to generate a Refresh Token from the Spotify OAuth API which is required in the walt-grover.rb script to continually generate a fresh OAuth token.

Before building and running the container, you must create a Spotify App on the developer dashboard,

• https://developer.spotify.com/

Copy the Client ID and Client Secret for the Spotify App as these are needed when running the container.

Set the Redirect URIs to http://localhost:9292/callback in the Spotify App settings, this must match exactly or the callback will not work.

Generating Spotify Refresh Token Using Callback

The callback container is only needed once in order to generate a refresh_token and only needed unless the refresh_token has expired.

Build the callback image from Dockerfile.callback,

docker build -f Dockerfile.callback -t callback .

Run the callback on localhost on port 9292 passing the CLIENT_ID and CLIENT_SECRET generated previously,

docker run -it --rm -e CLIENT_ID=*YOURCLIENTID* -e CLIENT_SECRET=*YOURCLIENTSECRET* -p 9292:9292 callback

In a web borwser go to http://localhost:9292 and click the login with spotify link. Authenticate with Spotify and a page with an access_token and refresh_token will generate. The refresh_token is used when running the waltgrover container to update Slack status.

Setting Slack Status to Current Spotify Track

Requires

• Slack Personal API Token
• Spotify client_id and client_secret - generated from Spotify App Dashboard
• Spotify refresh_token - generated from callback container
• Default status, emoji, and music emoji to use

Update the .env.example file in this repository with your Spotify, Slack, and other configurations, and copy to .env for the container to use as it's configuration.

Example .env file,

CLIENT_ID=*YOURSPOTIFYCLIENTID*
CLIENT_SECRET=*YOURSPOTIFYCLIENTSECRET*
REFRESH_TOKEN=*YOURSPOTIFYREFRESHTOKEN*
SLACK_PERSONAL_TOKEN=*YOURSLACKTOKEN*
DEFAULT_STATUS="Nothing currently playing"
DEFAULT_EMOJI=":speech_balloon:"
MUSIC_EMOJI=":musical_note:"

Build the waltgrover image from Dockerfile,

docker build -t waltgrover .

Run the waltgrover container by passing a .env file with required configuration,

docker run -it --rm --env-file=.env waltgrover

The container queries the Spotify API and sets Slack status to the current playing track every 3 minutes, if nothing is playing, a default status and emoji are set based on the DEFAULT_STATUS and DEFAULT_EMOJI env vars.
