Node.js library for the Amazon Web Services

A simple Node.js library to communicate with the Amazon Web Services API.

This version of aws-lib has been tested on Node v0.6.11.

It includes clients for the following services:

  • EC2
  • Product Advertising API
  • SimpleDB
  • SQS (Simple Queue Service)
  • SNS (Simple Notification Service)
  • SES (Simple Email Service)
  • ELB (Elastic Load Balancing Service) - added by Bernhard Weißhuhn
  • CW (CloudWatch)
  • IAM (Identity and Access Management)

Richard Rodger maintains a user-friendly SimpleDB library which is based on aws-lib.

aws-lib is designed to be easily extensible. If you want to add your own API client, have a look at ec2.js or simpledb.js and simply follow their example.


The following snippet implements an ec2 client and makes a call to DescribeInstances

var aws = require("aws-lib");

ec2 = aws.createEC2Client(yourAccessKeyId, yourSecretAccessKey);

ec2.call("DescribeInstances", {}, function(err, result) {

Which returns a JSON response similar to:

  "instanceState": {"code":"80","name":"stopped"},
  "reason":"User initiated (2010-07-28 19:37:54 GMT)"

Another example, using Product Advertising API:

prodAdv = aws.createProdAdvClient(yourAccessKeyId, yourSecretAccessKey, yourAssociateTag);

prodAdv.call("ItemSearch", {SearchIndex: "Books", Keywords: "Javascript"}, function(err, result) {

Will return a long list of books.

Most clients, such as ec2, ses, simpledb, etc. accept an optional third parameter options which should be an object of options used to instantiate the client. For example, the ec2 client could be instantiated with an options object like:

ec2 = aws.createEC2Client(yourAccessKeyId, yourSecretAccessKey, {version: '2010-08-31'});

which would instantiate the ec2 client, but using the 2010-08-31 API version. See the library code for each service to learn about other possible options.
