# recovr

[![godoc](http://img.shields.io/badge/godoc-reference-blue.svg?style=flat)](https://pkg.go.dev/github.com/dre1080/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](https://github.com/labstack/echo), [Goji](https://github.com/zenazn/goji), etc.).

## Installation

```

$ go get github.com/dre1080/recovr

```

## Usage

```go

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

```go

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

```go

import "github.com/zenazn/goji"

func main() {

    goji.Use(recovr.New())

    goji.Serve()

}

```
