Maintenance and support for SDK major versions

For information about maintenance and support for SDK major versions and their underlying dependencies, see the following in the AWS SDKs and Tools Shared Configuration and Credentials Reference Guide:

• AWS SDKs and Tools Maintenance Policy
• AWS SDKs and Tools Version Support Matrix

Getting started

To get started working with the SDK setup your project for Go modules, and retrieve the SDK dependencies with go get. This example shows how you can use the v2 SDK to make an API request using the SDK's Amazon DynamoDB client.

Initialize Project

$ mkdir ~/helloaws
$ cd ~/helloaws
$ go mod init helloaws

Add SDK Dependencies

$ go get github.com/aws/aws-sdk-go-v2/aws
$ go get github.com/aws/aws-sdk-go-v2/config
$ go get github.com/aws/aws-sdk-go-v2/service/dynamodb

Write Code

In your preferred editor add the following content to main.go

package main

import (
    "context"
    "fmt"
    "log"

    "github.com/aws/aws-sdk-go-v2/aws"
    "github.com/aws/aws-sdk-go-v2/config"
    "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 := config.LoadDefaultConfig(context.TODO(), config.WithRegion("us-west-2"))
    if err != nil {
        log.Fatalf("unable to load SDK config, %v", err)
    }

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

    // Build the request with its input parameters
    resp, err := svc.ListTables(context.TODO(), &dynamodb.ListTablesInput{
        Limit: aws.Int32(5),
    })
    if err != nil {
        log.Fatalf("failed to list tables, %v", err)
    }

    fmt.Println("Tables:")
    for _, tableName := range resp.TableNames {
        fmt.Println(tableName)
    }
}

Compile and Execute

$ go run .
Table:
tableOne
tableTwo

Getting Help

Please use these community resources for getting help. We use the GitHub issues for tracking bugs and feature requests.

• Ask a question on StackOverflow and tag it with the aws-sdk-go tag.
• Open a support ticket with AWS Support.
• If you think you may have found a bug, please open an issue.

This SDK implements AWS service APIs. For general issues regarding the AWS services and their limitations, you may also take a look at the Amazon Web Services Discussion Forums.

Opening Issues

If you encounter a bug with the AWS SDK for Go we would like to hear about it. Search the existing issues and see if others are also experiencing the same issue before opening a new issue. Please include the version of AWS SDK for Go, Go language, and OS you’re using. Please also include reproduction case when appropriate.

The GitHub issues are intended for bug reports and feature requests. For help and questions with using AWS SDK for Go please make use of the resources listed in the Getting Help section. Keeping the list of open issues lean will help us respond in a timely manner.

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.

Contributing. You can open pull requests for fixes or additions to the AWS SDK for Go 2.0. 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.

Overview

Package sdk is the official AWS SDK v2 for the Go programming language.

aws-sdk-go-v2 is the the v2 of the AWS SDK for the Go programming language.

Getting started

The best way to get started working with the SDK is to use `go get` to add the SDK and desired service clients to your Go dependencies explicitly.

go get github.com/aws/aws-sdk-go-v2
go get github.com/aws/aws-sdk-go-v2/config
go get github.com/aws/aws-sdk-go-v2/service/dynamodb

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"
    "log"

    "github.com/aws/aws-sdk-go-v2/aws"
    "github.com/aws/aws-sdk-go-v2/config"
    "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 := config.LoadDefaultConfig(context.TODO(),
   		config.WithRegion("us-west-2"),
   	)
    if err != nil {
        log.Fatalf("unable to load SDK config, %v", err)
    }

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

    // Build the request with its input parameters
    resp, err := svc.ListTables(context.TODO(), &dynamodb.ListTablesInput{
        Limit: aws.Int32(5),
    })
    if err != nil {
        log.Fatalf("failed to list tables, %v", err)
    }

    fmt.Println("Tables:")
    for _, tableName := range resp.TableNames {
        fmt.Println(tableName)
    }
}
