Debug Fiber APIs Like a Pro with GoRequestTracer: JSON Logging, DB Queries, and Panic Tracking

Why You Need This ## Installation ## Usage Example ## Example Log Output ## Key Features ## Contributing ## Why Star This Repo? If you’re building APIs or microservices in Go using Fiber, you know how hard it is to track HTTP requests, database queries, and unexpected panics. Meet GoRequestTracer, a lightweight Fiber middleware that: Imagine a production API receiving hundreds of requests per second. GoRequestTracer solves all this by centralizing request and DB tracking in a structured JSON log, making debugging faster and simpler. If using SQLite, ensure CGO is enabled. GoRequestTracer is open to contributions! Fork, create a branch, and submit a Pull Request. Check the repo here: GoRequestTracer on GitHub If you’re building Go APIs with Fiber or just want to monitor DB queries and panics in production efficiently, this repo will save you hours of debugging. 🌟 Star the repo to support it and stay updated!
