The AWS SDK for JavaScript v2 has reached end-of-support. We recommend that you migrate to [AWS SDK for JavaScript v3](https://docs.aws.amazon.com//sdk-for-javascript/v3/developer-guide/). For additional details and information on how to migrate, please refer to this [announcement](https://aws.amazon.com/blogs//developer/announcing-end-of-support-for-aws-sdk-for-javascript-v2/).

# Prerequisites
<a name="jssdk-prerequisites"></a>

Before you use the AWS SDK for JavaScript, determine whether your code needs to run in Node.js or web browsers. After that, do the following: 
+ For Node.js, install Node.js on your servers if it is not already installed.
+ For web browsers, identify the browser versions you need to support.

# Setting Up an AWS Node.js Environment
<a name="setting-up-node"></a>

To set up an AWS Node.js environment in which you can run your application, use any of the following methods:
+ Choose an Amazon Machine Image (AMI) with Node.js pre-installed and create an Amazon EC2 instance using that AMI. When creating your Amazon EC2 instance, choose your AMI from the AWS Marketplace. Search the AWS Marketplace for Node.js and choose an AMI option that includes a version of Node.js (32-bit or 64-bit) pre-installed.
+ Create an Amazon EC2 instance and install Node.js on it. For more information about how to install Node.js on an Amazon Linux instance, see [Tutorial: Setting Up Node.js on an Amazon EC2 Instance](setting-up-node-on-ec2-instance.md).
+ Create a serverless environment using AWS Lambda to run Node.js as a Lambda function. For more information about using Node.js within a Lambda function, see [Programming Model (Node.js)](https://docs.aws.amazon.com/lambda/latest/dg/programming-model.html) in the *AWS Lambda Developer Guide*.
+ Deploy your Node.js application to AWS Elastic Beanstalk. For more information on using Node.js with Elastic Beanstalk, see [Deploying Node.js Applications to AWS Elastic Beanstalk](https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/create_deploy_nodejs.html) in the *AWS Elastic Beanstalk Developer Guide*. 

# Web Browsers Supported
<a name="browsers-supported"></a>

The SDK for JavaScript supports all modern web browsers, including these minimum versions:
