New features added to the generally available version include bound parameters, streams, IAM (identity and access management) roles for EC2 (Elastic Compute Cloud) instances, proxies and version locking. The latter feature allows users to lock into an API version for a service, which Amazon recommends if the API is relied on for production code. This way companies can isolate themselves from changes in updates of the SDK, it said.
Applications written using the SDK can be integrated with a long list of Amazon's cloud services, including Amazon's Relational Database Service and its Virtual Private Cloud offering, which lets users create logically isolated virtual servers and an optional VPN connection to their own data center.
Recently, Amazon also announced a version of Elastic Beanstalk for Node.js-based applications. Elastic Beanstalk aims to make it easier to quickly deploy and manage applications in Amazon's cloud. The tool can also be used with Java, PHP, Python, Ruby and .Net applications.
The preferred way to install the AWS SDK for Node.js is to use the npm package manager for Node.js, according to Amazon's documentation for the kit, which also includes a configuration guide and code examples.
