An example app that helps enforce channel naming conventions.

Setup

1. Clone this repo, or remix this on Glitch

git clone https://github.com/slackapi/template-channel-naming.git

Remix on Glitch

2. Create a Slack app

  1. Create an app at https://api.slack.com/apps
  2. At Bot Users, add a new bot user.
  3. Click on OAuth & Permissions and select the following scopes: chat:write, channels:read, chat:write.public
  4. Enable the interactive messages (See below Enable Interactive Messages)
  5. Enable events (See below Enable the Events API)
  6. Click 'Save Changes' and install the app to all channels (You should get an OAuth access token after the installation

3. Run locally or Remix on Glitch

  1. Set the following environment variables in .env (copy from .env.sample):
    • SLACK_ACCESS_TOKEN: Your app's xoxa- token (available on the Install App page)
    • SLACK_SIGNING_SECRET: Your app's Verification Token (available on the Basic Information page)
    • PORT: The port that you want to run the web server on (Default: 5000)
  2. If you're running the app locally:
    • Start the app (npm start)

4. Enable Interactive Messages

  1. Click on Interactive Components and enable the feature.
  2. Set the Request URL to your server URL + /interactions

If you did "Remix" on Glitch, it auto-generate a new URL with two random words, so your Request URL should be like: https://fancy-feast.glitch.me/command.

Enable the Events API

  1. Click on Events Subscriptions and enable events.
  2. Set the Request URL to your server (e.g. https://yourname.ngrok.com) or Glitch URL + /events
  3. On the same page, scroll down to Subscribe to Bot Events and subscribe to the channel_created and channel_rename events.
