raygun4go
raygun4go adds Raygun-based error handling to your golang code. It catches all occuring errors, extracts as much information as possible and sends the error to Raygun via their REST-API.
Getting Started
Installation
$ go get github.com/MindscapeHQ/raygun4go
Basic Usage
Include the package and then defer the HandleError-method as soon as possible in a context as global as possible. In webservers, this will probably be your request handling method, in all other programs it should be your main-method. Having found the right spot, just add the following example code:
raygun, err := raygun4go.New("appName", "apiKey")
if err != nil {
log.Println("Unable to create Raygun client:", err.Error())
}
raygun.Silent(true)
defer raygun.HandleError()
where appName is the name of your app and apiKey is your
Raygun-API-key. If your program runs into a panic now (which you can easily
test by adding panic("foo") after the call to defer), the handler will
print the resulting error message. If you remove the line
raygun.Silent(true)
the error will be sent to Raygun using your API-key.
Options
The client returned by New has several chainable option-setting methods
| Method | Description |
|---|---|
Silent(bool) |
If set to true, this prevents the handler from sending the error to Raygun, printing it instead. |
Request(*http.Request) |
Adds the responsible http.Request to the error. |
Version(string) |
If your program has a version, you can add it here. |
Tags([]string) |
Adds the given tags to the error. These can be used for filtering later. |
CustomData(interface{}) |
Add arbitrary custom data to you error. Will only reach Raygun if it works with json.Marshal(). |
User(string) |
Add the name of the affected user to the error. |
