🛠️ TypeScript Product Validation & Jira Integration

📌 Project Description

This project is a TypeScript-based backend application that processes a list of products, validates them based on predefined rules, and automatically creates Jira tickets for invalid products.

It simulates a real-world Content-Tech / Data Processing workflow, where product data is:

1. Retrieved or defined
2. Validated against business rules
3. Logged if valid ✅
4. Sent to Jira as an issue if invalid ❌

---

🚀 Features

• ✅ Product validation logic
• 🔄 Iterative processing of multiple products
• 🐞 Automatic Jira ticket creation for invalid products
• ⚠️ Error handling for failed API requests
• 📜 Console-based logging for tracking workflow

🧪 Sample Output

Product 1 is valid
Creating Jira Ticket for product 2

🔍 How It Works

Step 1: Product Processing

• A list of products is iterated one by one.

Step 2: Validation

• Each product is checked against validation rules.
• Valid products → Logged in console
• Invalid products → Sent for Jira ticket creation

Step 3: Jira Integration

• API call is made to create a Jira issue.
• If the request fails (e.g., status code 400), an error is logged.

❗ Common Errors

🔴 Jira टिकट creation failed (400 error)

Possible reasons:

• Invalid payload format
• Missing required fields
• Incorrect API credentials
• Wrong Jira endpoint

---

🔧 Improvements (Next Steps)

• ✅ Add environment variables for API keys
• ✅ Improve validation rules
• ✅ Add retry mechanism for failed Jira requests
• ✅ Store logs in a file instead of console
• ✅ Add unit tests using Jest
