CloudFlare D1 API Response logger

API Logging with Postman, Cloudflare Worker & D1 Database

Introduction

Cloudflare Workers, D1, and Postman offer an efficient and scalable solution for capturing and storing API request data. With Cloudflare D1 providing 1GB of free storage, this system is perfect for small to medium-scale logging needs. You can effortlessly log data such as API request details, headers, response times, and body content with minimal setup.


Why Use Postman, Cloudflare Worker, and D1?

  • Postman: A powerful tool for testing and sending API requests. It simplifies the process of automating tests and logging API calls.
  • Cloudflare Worker: A serverless edge function that processes and logs API requests. It captures the request details, like headers and response data, and stores them in D1, all with low latency.
  • Cloudflare D1: Cloudflareโ€™s serverless SQL database solution. Itโ€™s fast, secure, and designed for lightweight logging use cases. Best of all, D1 provides 1GB of free storage, making it perfect for logging and small-scale applications.

How It Works

  1. Postman sends API requests to the Cloudflare Worker.
  2. The Worker intercepts the request, logs relevant details like the timestamp, method, headers, and response time.
  3. This data is stored in Cloudflare D1โ€™s serverless database.
  4. With D1โ€™s edge network, the data is stored with high availability and low latency.

The entire process happens quickly at the edge, ensuring fast, real-time logging without the overhead of managing servers or infrastructure.
