Slack Template

This is a Slack template for creating a great Slack app using Python and Starlette.

Prerequisites

• Python (3.13 or later)
• uv
• A Slack workspace where you have permissions to install apps
• Tunneling tool (for local development)

Setting up the Slack App

1. Go to https://api.slack.com/apps and click "Create New App".
2. Choose "From an app manifest" and select your workspace.
3. Copy and paste the manifest in manifest.yml, replacing YOUR_URL with your URL (we'll set this up later):
4. Review and create the app.
5. In the "Basic Information" section, note down the App Id, Client Id, Client Secret, Signing Secret .
6. Go to "OAuth & Permissions" and install the app to your workspace. Note down the "Bot User OAuth Token".

Setting up the Project

1. Clone the repository:

   git clone https://github.com/your-repo/slack-template.git
   cd professor-bloom
   

2. Install dependencies:

   uv sync
   source .venv/bin/activate # for bash/zsh
   source .venv/bin/activate.fish # for fish
   source .venv/bin/activate.csh # for csh
   source .venv/bin/activate.ps1 # for powershell
   

3. Copy the .env.sample file to .env:

   cp .env.sample .env
   

4. Edit the .env file and fill in the values:

   PORT=3000
   ENVIRONMENT="development"
   
   SLACK_BOT_TOKEN="bot-token"
   SLACK_SIGNING_SECRET="signing-secret"
   SLACK_APP_TOKEN="app-token" # This is optional - recommended to use socket mode in dev because it allows you to run the app locally without needing to tunnel. Not recommended for production.
   
   SLACK_HEARTBEAT_CHANNEL="channel-id"
   

   Replace the values with your actual parameters.

Running the Application

1. Start your tunneling tool and expose the local server. (Not needed in socket mode with SLACK_APP_TOKEN set)

   Note the HTTPS URL you get.

2. Update your Slack app's request URLs:

   • Go to your Slack app's settings.
   • In "Event Subscriptions" and "Interactivity & Shortcuts", update the request URL to your HTTPS URL followed by /slack/events.
   • In "OAuth & Permissions", update Redirect URLs to your HTTPS URL followed by /slack/oauth_redirect.

3. Start the application:

   app
   

Your Slack app should now be running and connected to your Slack workspace!
