hubot-slack

Important Notice

The original hubot-slack is no longer under active development. Slack recommends taking a look at Bolt for JS with Socket Mode first if you're getting started.

But I'm going to maintain this fork as I continue to evolve Hubot. So feel free to use this one.

Installation

npm i @hubot-friends/hubot-slack hubot

This is a Hubot adapter to use with Slack.

Comprehensive documentation is available.

Adapter Configuration

• Create (or use an existing one) a Slack Workspace
• Create a Slack App
• Create an App-Level Token and give it connections:write scope. This will be the HUBOT_SLACK_APP_TOKEN environment variable. The adapter will use this token to authenticate via Slacks Socket Mode (WebSockets)
• Create a Bot Token. This will be the HUBOT_SLACK_BOT_TOKEN environment variable. The adapter will use this token to POST messages to Slack's HTTP API.
• Make sure to give the Slack App the scope permissions noted below in "Notes on using SocketMode".

Startup

An example command to start the app on MacOS is the following. Assuming there is a file called .env with the following environment variables set:

HUBOT_SLACK_APP_TOKEN=xapp-1-...
HUBOT_SLACK_BOT_TOKEN=xoxb-...

Set the environment variables to the values you created for your Slack Apps App-Level Token (HUBOT_SLACK_APP_TOKEN) and Bot Token (HUBOT_SLACK_BOT_TOKEN).

env $(cat .env | grep -v \"#\" | xargs -0) PORT=8080 hubot -a @hubot-friends/hubot-slack -n mybot

Another way to start the app in MacOS or Linux is:

HUBOT_SLACK_APP_TOKEN=xapp-1... HUBOT_SLACK_BOT_TOKEN=xoxb-... PORT=8080 hubot -a @hubot-friends/hubot-slack -n mybot
