DeferPanic: Open-Source Panic Management for Go
An open-source error handling library for Go that wraps and manages panics to prevent crashes, providing functions to recover from panics and log details.
What is DeferPanic?
DeferPanic is an open-source error handling library for the Go programming language that focuses on gracefully handling panic errors. It was created to help Go developers easily wrap sections of code that may panic to prevent crashes and enable better error recovery.
Some key features of DeferPanic include:
- Simple panic wrapping and recovery functions
- Logging of full panic traces before allowing the panic to continue
- Capture and retrieval of original error values
- Flexible configuration for custom panic handling logic
- Integration helpers for popular Go web frameworks like Gin
By calling a single DeferPanic method before and after risky code, panics can be intercepted, logged, and program execution can continue instead of abruptly crashing. Developers can focus handling errors properly instead of littering code with numerous error checks.
DeferPanic was designed to complement Go's built-in panic/recover features with an easy-to-use API. It helps make Go error handling more reliable and helps prevent crashes in complex applications. The project is open source and actively maintained on GitHub.
