Using the AWS SDK for Go Encryption Client

Overview AWS SDK for Go released the encryption client last year, and some of our customers have asked us how to use it. We’re very excited to show you some examples in this blog post. Before we get into the examples, let’s look at what client-side encryption is and why you might want to use […]

AWS SDK for Go Adds Error Code Constants

The AWS SDK for Go v1.6.19 release adds generated constants for all modeled service response error codes. These constants improve discoverability of the error codes that a service can return, and reduce the chance of typos that can cause errors to be handled incorrectly. You can find the new error code constants within each of the SDK’s service client […]

The setters wrap this functionality internally so you don’t have to. The setters are a convenient way to reduce the need to use aws.String and similar utilities. The following code shows […]

Mocking Out the AWS SDK for Go for Unit Testing

In our previous post, we showed how you could use the request handler stack in the AWS SDK for Go to extend or modify how requests are sent and received. Now, we’d like to expand the idea of extending the SDK and discuss how you can unit test code that uses the SDK. The SDK’s service clients are a […]
