The aws-sdk npm package is the official AWS SDK for JavaScript, providing JavaScript objects for AWS services including Amazon S3, EC2, DynamoDB, and more. It allows developers to interact with AWS services programmatically, enabling them to build scalable solutions with AWS infrastructure.

What are aws-sdk's main functionalities?

Interacting with Amazon S3

This code sample demonstrates how to retrieve an object from an Amazon S3 bucket using the aws-sdk.

{"const AWS = require('aws-sdk');
const s3 = new AWS.S3();
const params = { Bucket: 'myBucket', Key: 'myKey' };
s3.getObject(params, function(err, data) {
  if (err) console.log(err, err.stack);
  else console.log(data);
});"}

Managing EC2 Instances

This code sample shows how to describe EC2 instances, providing information about instances running in your AWS account.

{"const AWS = require('aws-sdk');
const ec2 = new AWS.EC2();
const params = { InstanceIds: ['i-1234567890abcdef0'] };
ec2.describeInstances(params, function(err, data) {
  if (err) console.log(err, err.stack);
  else console.log(data);
});"}

Working with DynamoDB

This code sample illustrates how to retrieve an item from a DynamoDB table using the aws-sdk.

{"const AWS = require('aws-sdk');
const dynamoDB = new AWS.DynamoDB();
const params = {
  TableName: 'myTable',
  Key: {
    'myKey': { S: 'myKeyValue' }
  }
};
dynamoDB.getItem(params, function(err, data) {
  if (err) console.log(err, err.stack);
  else console.log(data);
});"}

The official JavaScript implementation of the AWS SDK for Node.js.

Installing

The preferred way to install the AWS SDK for Node.js is to use the npm package manager for Node.js. Simply type the following into a terminal window:

npm install aws-sdk

Please Note: Installing the aws-sdk npm package on Windows may display errors while trying to install the optional dependency for libxmljs. This error can be safely ignored.

Usage

After you've installed the SDK, you can require the AWS package in your node application using require:

var AWS = require('aws-sdk');

Here is a quick example that makes some requests against Amazon S3 with the SDK:

// Load the AWS SDK for Node.js
var AWS = require('aws-sdk');

/**
 * Don't hard-code your credentials!
 * Load them from disk or your environment instead.
 */
// AWS.config.update({accessKeyId: 'AKID', secretAccessKey: 'SECRET'});

// Instead, do this:
AWS.config.loadFromPath('./path/to/credentials.json');

// Set your region for future requests.
AWS.config.update({region: 'us-east-1'});

// Create a bucket and put something in it.
var s3 = new AWS.S3();
s3.client.createBucket({Bucket: 'myBucket'}, function() {
  var data = {Bucket: 'myBucket', Key: 'myKey', Body: 'Hello!'};
  s3.client.putObject(data, function(err, data) {
    if (err) {
      console.log("Error uploading data: ", err);
    } else {
      console.log("Successfully uploaded data to myBucket/myKey");
    }
  });
});
