5.5.1 Step 1—Configure Your Credentials

You need to provide credentials to AWS so that only your account and its resources are accessed by the SDK. To hold this information, we recommend you create a shared credentials file.

• see Loading Credentials in Node.js from the Shared Credentials File

Your credentials file should resemble the following example.

[default]
aws_access_key_id = YOUR_ACCESS_KEY_ID
aws_secret_access_key = YOUR_SECRET_ACCESS_KEY

You can determine whether you have set your credentials correctly by executing the following code with node:

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

AWS.config.getCredentials(function(err) {
  if (err) console.log(err.stack);
  // credentials not loaded
  else {
    console.log("Access key:", AWS.config.credentials.accessKeyId);
    console.log("Secret access key:", AWS.config.credentials.secretAccessKey);
  }
});

Similarly, if you have set your region correctly in your config file, you can display that value by setting the ‘AWS_SDK_LOAD_CONFIG’ environment variable to a truthy value and using the following code:

export AWS_SDK_LOAD_CONFIG=1

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

console.log("Region: ", AWS.config.region);
