The Cheese Touch, but over Slack. Idea taken from Diary of a Wimpy Kid. Why did I make this? Besides having a reason to practice Go, I have no clue. 🤷♂
You’ll need to create a Slack app (not a classic one) with at least the following bot token scopes. The reasons each scope is required are also included:
channels:history
: Used to check if a new user sent a message to pass the cheese touch. Only works if the app has been invited to the channel.chat:write
: Used for sending messages when the cheese touch starts or gets passed to someone else.groups:history
: Used to check if a new user sent a message to pass the cheese touch. Only works if the app has been invited to the channel.reactions:read
: For listening to users that “touch” the cheese via reaction.
Then you’ll need to subscribe the app to a few events. The server has an endpoint open at /slack/events
, so when you’re asked for a request URL, just put https://<SERVER>/slack/events
. Only the following events are needed:
message.channels
message.groups
reaction_added
You can optionally create a slash command, /cheesewho
, that tells the user who has the Cheese Touch!. Point it to the URL https://<SERVER>/slack/cheesewho
Here are all the variables you need to set up, with hints.
# Port to run the app server on
PORT=3000
# Redis database to record the user with the cheese touch
REDIS_URL=redis://…
# App config. Obtained from the "Basic Information" page of your app.
SLACK_CLIENT_BOT_TOKEN=xoxb-…
SLACK_VERIFICATION_TOKEN=xxxx…
# Run it
make
# Run it explicitly from a binary
make build
./bin/cheese
After you’ve followed all the above steps, you should see something like this:
Starting Cheese…
Listening on port 3000
Enjoy! 🧀
