Loading Credentials in Node.js from Environment Variables - AWS SDK for JavaScript

We announced the upcoming end-of-support for AWS SDK for JavaScript v2. We recommend that you migrate to AWS SDK for JavaScript v3. For dates, additional details, and information on how to migrate, please refer to the linked announcement.

Loading Credentials in Node.js from Environment Variables

The SDK automatically detects AWS credentials set as variables in your environment and uses them for SDK requests, eliminating the need to manage credentials in your application. The environment variables that you set to provide your credentials are:

  • AWS_ACCESS_KEY_ID

  • AWS_SECRET_ACCESS_KEY

  • AWS_SESSION_TOKEN

For more details on setting environment variables, see Environment variables support in the AWS SDKs and Tools Reference Guide.
