Libraries, samples, and tools to help Go developers develop AWS Lambda functions.

To learn more about writing AWS Lambda functions in Go, go to the official documentation

Getting Started

// main.go
package main

import (
	"github.com/aws/aws-lambda-go/lambda"
)

func hello() (string, error) {
	return "Hello λ!", nil
}

func main() {
	// Make the handler available for Remote Procedure Call by AWS Lambda
	lambda.Start(hello)
}

Building your function

Preparing a binary to deploy to AWS Lambda requires that it is compiled for Linux and placed into a .zip file.

For developers on Linux and macOS

# Remember to build your handler executable for Linux!
GOOS=linux GOARCH=amd64 go build -o main main.go
zip main.zip main

For developers on Windows

Windows developers may have trouble producing a zip file that marks the binary as executable on Linux. To create a .zip that will work on AWS Lambda, the build-lambda-zip the tool may be helpful.
