The @aws-sdk/credential-provider-http package is designed to retrieve AWS credentials from a remote endpoint, such as the Amazon EC2 Instance Metadata Service (IMDS) or a custom HTTP endpoint. It is part of the AWS SDK for JavaScript (v3), which is a modular collection of software for interacting with AWS services. This package is particularly useful for applications running on AWS infrastructure that need to securely obtain temporary credentials without hardcoding them.

What are @aws-sdk/credential-provider-http's main functionalities?

Retrieving credentials from EC2 Instance Metadata Service (IMDS)

This feature allows applications running on an Amazon EC2 instance to automatically retrieve temporary AWS credentials. The credentials are provided by the EC2 Instance Metadata Service without requiring manual credential management.

const { fromInstanceMetadata } = require('@aws-sdk/credential-provider-http');

const credentials = fromInstanceMetadata();

Retrieving credentials from a custom HTTP endpoint

This feature enables the retrieval of AWS credentials from a custom HTTP endpoint. It is useful for scenarios where credentials are centrally managed and distributed via an internal HTTP service.

const { fromHttp } = require('@aws-sdk/credential-provider-http');

const credentials = fromHttp({
  url: 'http://my-custom-credential-provider/',
  requestOptions: { // Optional HTTP request options
    method: 'GET'
  }
});
