Writing a Lambda function in Go

Follow the steps in this section to create your first Lambda function in Go from scratch:

1. To write a Lambda function, we need to install some dependencies. Hence, open a new terminal session, and install the Go Lambda package using the following command:

go get github.com/aws/aws-lambda-go/lambda

2. Next, open your favorite Go IDE or editor; in my case, I will work with VS Code. Create a new project directory in your GOPATH and then paste the following content into a main.go file:

package main

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

funchandler() (string, error){
return"Welcome to Serverless world", nil
}

funcmain() {
  lambda.Start(handler)
}

The previous code uses the lambda.Start() method to register an entry-point handler that contains the code that will be executed when a Lambda function is invoked. Each language supported by Lambda has its own requirements for how a function handler can be defined. For Golang, the handler signature must meet the following...
