Heroku Webhook POC

A simple Node.js application that demonstrates webhook processing in a Heroku environment. This is a proof of concept for a background job processing system.

Simplified Architecture

For this POC, we're using a simplified architecture:

1. Express web server that receives webhook trigger requests
2. In-memory job queue for demonstration purposes
3. Asynchronous job processing using setTimeout

The app simulates a job queue system without external dependencies, making it simple to understand and deploy.

Setup

1. Create a Heroku app:

heroku create

2. Deploy to Heroku:

git push heroku main

Usage

To trigger a webhook, send a POST request to /trigger-webhook:

curl -X POST https://your-app-name.herokuapp.com/trigger-webhook

This will add a job to the in-memory queue and process it asynchronously, calling the configured webhook URL.

Monitoring

You can use the following endpoints to monitor jobs:

• GET /jobs - List all jobs
• GET /job/:id - Get status of a specific job
• GET / - Health check endpoint

You can also view the logs:

heroku logs --tail
