Detailed technical documentation on using RudderStack’s Go SDK to send events to various destinations

RudderStack’s Go SDK allows you to track your customer event data from your Go code. Once enabled, the event requests hit the RudderStack servers. RudderStack then routes the events to the specified destination platforms as configured by you.

You can find this SDK in our GitHub repository.

Installing the RudderStack Go SDK

The RudderStack Go SDK package can be simply installed via the go get command. It is recommended that you use a tool like Godep to avoid issues related to the breaking API changes introduced between major versions of the library.

To install it in the GOPATH, run the following:

go get github.com/rudderlabs/analytics-go

Using the RudderStack Go SDK

To use the SDK, run the following code snippet:

package main
import (
"github.com/rudderlabs/analytics-go"
)
func main() {
// Instantiates a client to use send messages to the Rudder API.
client := analytics.New(WRITE_KEY, DATA_PLANE_URL)
// Enqueues a track event that will be sent asynchronously.
client.Enqueue(analytics.Track{
UserId: "test-user",
Event: "test-snippet",
})
// Flushes any queued messages and closes the client.
client.Close()
}

Alternatively,

package main
import (
"github.com/rudderlabs/analytics-go"
)
func main() {
// Instantiates a client to use send messages to the Rudder API.
client, _ := analytics.NewWithConfig(WRITE_KEY, DATA_PLANE_URL,
analytics.Config{
Interval: 30 * time.Second,
BatchSize: 100,
Verbose: true,
})
// Enqueues a track event that will be sent asynchronously.
client.Enqueue(analytics.Track{
UserId: "test-user",
Event: "test-snippet",
})
// Flushes any queued messages and closes the client.
client.Close()
}
