You can hard-code credentials by passing the credential information to the configuration object using

AWS.config.update():

AWS.config.update({accessKeyId: 'akid', secretAccessKey: 'secret'});

Setting the Region

The AWS SDK for Node.js doesn't select the region by default.You can choose a region similarly to

setting credentials by either loading from disk or using AWS.config.update():

AWS.config.update({region: 'us-west-1'});

Service-Specific Configuration

Occasionally, you might want to apply configuration only to one service. For instance, you want to use

multiple EC2 objects in different regions.You can do this by passing configuration data directly to the

service object constructor:

var ec2 = new AWS.EC2({region: 'ap-southeast-2', maxRetries: 15});

Note that the constructor takes all of the same configuration data as the AWS.config object described

above, including credential information.

Immutable Configuration Data

Global configuration changes apply to all requests for all newly created services. Any newly created

service will merge its local options on top of the global configuration data at the time of creation.This

means that any future updates to the global AWS.config object will not apply to existing service objects.

These services would have to be manually updated with the new configuration data, or recreated using

the following command (assuming an existing s3 service object):

s3 = new AWS.S3(s3.config);
