Recover

Recover middleware recovers from panics anywhere in the chain, prints the stack trace, and passes control to the centralized HTTPErrorHandler.

All core middleware lives in the middleware package:

import "github.com/labstack/echo/v5/middleware"

Usage

e.Use(middleware.Recover())

Custom configuration

e := echo.New()
e.Use(middleware.RecoverWithConfig(middleware.RecoverConfig{
  StackSize: 1 << 10, // 1 KB
}))

The example above uses a StackSize of 1 KB and default values for DisableStackAll and DisablePrintStack.
