Build a Slack App in 10 Minutes with MongoDB Stitch

This tutorial demonstrates building a Slack app, "URL Stash," using MongoDB Stitch to store and retrieve URLs. The app leverages Slack slash commands for user interaction and MongoDB Atlas for data persistence. No server management is required thanks to Stitch's serverless architecture.

Key Steps:

1. Slack App Setup: Create a new Slack app via the Slack API Console. This involves creating a workspace (if needed) and configuring the app.

2. MongoDB Atlas Configuration: Set up a free MongoDB Atlas cluster, database (e.g., exampledb), and collection (e.g., examplecoll) to store the URLs.

3. MongoDB Stitch Integration: Create a Stitch app linked to your Atlas cluster. Within Stitch, create an HTTP service with an incoming webhook. This webhook URL will be used in the Slack app.

4. Stitch Service Function: Write a JavaScript function for the HTTP service to handle Slack commands. This function uses a switch statement to process commands like /url stash [URL], /url list, and /url remove [URL], interacting with the MongoDB database accordingly. The provided code snippet shows an example implementation.

5. Slack Slash Command: In the Slack app console, create a slash command (e.g., /url). Configure it to point to the Stitch HTTP service's webhook URL.

6. App Installation and Testing: Install the app in your Slack workspace and test the slash commands.

Benefits of using MongoDB Stitch:

• Serverless: No server infrastructure to manage.
• Ease of Integration: Simplified integration with Slack and MongoDB.
• Scalability: Stitch handles scaling automatically.

This streamlined process allows for rapid development of functional Slack apps without the complexities of traditional server-side development. The provided code and screenshots offer a clear path to building your own URL Stash app or similar integrations.
