:collision: Go HTTP middleware that catches any panics and serves a proper error response.
recovr
Recovr is a HTTP middleware that catches any panics and serves a proper error response.
Works with all frameworks that support native http handler (eg. Echo, Goji, etc.).
Installation
$ go get github.com/dre1080/recovr
Usage
package main
import (
"net/http"
"github.com/dre1080/recovr"
)
var myPanicHandler = http.HandlerFunc(func(w http.ResponseWriter, r *http.Request) {
panic("you should not have a handler that just panics ;)")
})
func main() {
recovery := recovr.New()
app := recovery(myPanicHandler)
http.ListenAndServe("0.0.0.0:3000", app)
}
Examples
Echo Example
import "github.com/labstack/echo/v4"
func main() {
e := echo.New()
e.Use(echo.WrapMiddleware(recovr.New()))
e.Logger.Fatal(e.Start(":1323"))
}
Goji Example
import "github.com/zenazn/goji"
func main() {
goji.Use(recovr.New())
goji.Serve()
}
