rollbar is a Golang Rollbar client that makes it easy to report errors to Rollbar with full stacktraces. Errors are sent to Rollbar asynchronously in a background goroutine.

Because Go's error type doesn't include stack information from when it was set or allocated, we use the stack information from where the error was reported.

NOTE: This is a clone of http://github.com/stvp/rollbar extended to support use on Google AppEngine.

API docs on godoc.org

package main

import (
  "github.com/stvp/rollbar"
)

func main() {
  rollbar.Token = "MY_TOKEN"
  rollbar.Environment = "production" // defaults to "development"

  result, err := DoSomething()
  if err != nil {
    rollbar.Error(rollbar.ERR, err)
  }

  rollbar.Message("info", "Message body goes here")

  rollbar.Wait()
}

On Google AppEngine, instead of invoking rollbar package functions directly, create a client passing *http.Request:

rollbar.NewGaeClient(r).Error("error", err)

Set up a dummy project in Rollbar and pass the access token as an environment variable to go test:

TOKEN=f0df01587b8f76b2c217af34c479f9ea go test

And verify the reported errors manually in the Rollbar dashboard.
