Overview

Package recover provides panic recovery middleware for the aarv framework.

It catches panics in downstream handlers, logs the stack trace, and returns a 500 JSON error response instead of crashing the server.

Functions

func New

func New(config ...Config) aarv.Middleware

New creates a panic recovery middleware with optional configuration. If no config is provided, DefaultConfig is used.

Types

type Config

type Config struct {
	// StackSize is the maximum size of the stack trace buffer in bytes.
	// Default: 4096.
	StackSize int

	// DisableStackAll disables capturing the stack of all goroutines.
	// When false (default), runtime.Stack is called with all=true.
	DisableStackAll bool

	// DisablePrintStack disables logging the stack trace.
	// When true, the panic value is still logged but the stack trace is omitted.
	DisablePrintStack bool
}
