AWS SDK for Go v2

aws-sdk-go-v2 is the Developer Preview (aka beta) for the v2 AWS SDK for the Go programming language. This Developer Preview is provided to receive feedback from the language community on SDK changes prior to the final release. As such users should expect the SDK to release minor version releases that break backwards compatability. The release notes for the breaking change will include information about the breaking change, and how you can migrate to the latest version.

Check out the Issues and Projects for design and updates being made to the SDK. The v2 SDK requires a minimum version of Go 1.12.

We'll be expanding out the Issues and Projects sections with additional changes to the SDK based on your feedback, and SDK's core's improvements. Check the the SDK's CHANGE_LOG for information about the latest updates to the SDK.

Project Status

The SDK is in preview state as we work to design and implement potentially breaking changes to the SDK as we update the SDK's layout and usage patterns based on your feedback. You can also expect periodic service API model updates as well.

We are actively seeking community feedback for several changes to the SDK. Please review our design page on issues that are currently pending community feedback.

Users should expect significant changes that could affect the following (non-exhaustive) areas:

• Package Locations
  • Includes Location of Service API Types
• Modularization
• Credential Providers
• Paginators
• Waiters
• Service Endpoint Resolution
• Minimum Supported Go Release following the Language Release Policy

Getting started

The best way to get started working with the SDK is to use go get to add the SDK to your Go Workspace or application using Go modules.

go get github.com/aws/aws-sdk-go-v2

Without Go Modules, or in a GOPATH use the /... suffix on the go get to retrieve all of the SDK's dependencies.

go get github.com/aws/aws-sdk-go-v2/...

Hello AWS

This example shows how you can use the v2 SDK to make an API request using the SDK's Amazon DynamoDB client.

package main

import (
	"context"
	"fmt"

	"github.com/aws/aws-sdk-go-v2/aws"
	"github.com/aws/aws-sdk-go-v2/aws/endpoints"
	"github.com/aws/aws-sdk-go-v2/aws/external"
	"github.com/aws/aws-sdk-go-v2/service/dynamodb"
)

func main() {
	// Using the SDK's default configuration, loading additional config
	// and credentials values from the environment variables, shared
	// credentials, and shared configuration files
	cfg, err := external.LoadDefaultAWSConfig()
	if err != nil {
		panic("unable to load SDK config, " + err.Error())
	}

	// Set the AWS Region that the service clients should use
	cfg.Region = endpoints.UsWest2RegionID

	// Using the Config value, create the DynamoDB client
	svc := dynamodb.New(cfg)

	// Build the request with its input parameters
	req := svc.DescribeTableRequest(&dynamodb.DescribeTableInput{
		TableName: aws.String("myTable"),
	})

	// Send the request, and get the response or error back
	resp, err := req.Send(context.Background())
	if err != nil {
		panic("failed to describe table, "+err.Error())
	}

	fmt.Println("Response", resp)
}

Feedback and contributing

The v2 SDK will use GitHub Issues to track feature requests and issues with the SDK. In addition, we'll use GitHub Projects to track large tasks spanning multiple pull requests, such as refactoring the SDK's internal request lifecycle. You can provide feedback to us in several ways.

GitHub issues. To provide feedback or report bugs, file GitHub Issues on the SDK. This is the preferred mechanism to give feedback so that other users can engage in the conversation, +1 issues, etc. Issues you open will be evaluated, and included in our roadmap for the GA launch.

Gitter channel. For more informal discussions or general feedback, check out our Gitter channel for the SDK. The Gitter channel is also a great place to ask general questions, and find help to get started with the 2.0 SDK Developer Preview.

Contributing. You can open pull requests for fixes or additions to the AWS SDK for Go 2.0 Developer Preview release. All pull requests must be submitted under the Apache 2.0 license and will be reviewed by an SDK team member before being merged in. Accompanying unit tests, where possible, are appreciated.
