@aws-sdk/token-providers is a package within the AWS SDK for JavaScript that provides various token providers for acquiring and managing tokens used for authentication and authorization with AWS services.

What are @aws-sdk/token-providers's main functionalities?

FromSSOToken

This feature allows you to create a token provider that retrieves tokens from AWS Single Sign-On (SSO). The code sample demonstrates how to configure the SSO token provider with a specific SSO session.

const { fromSSOToken } = require('@aws-sdk/token-providers');
const ssoTokenProvider = fromSSOToken({
  ssoClient: new SSOClient({ region: 'us-west-2' }),
  ssoSession: 'my-sso-session'
});

FromWebIdentityToken

This feature allows you to create a token provider that retrieves tokens from a web identity token file. The code sample demonstrates how to configure the web identity token provider with a specific role ARN and token file path.

const { fromWebIdentityToken } = require('@aws-sdk/token-providers');
const webIdentityTokenProvider = fromWebIdentityToken({
  roleArn: 'arn:aws:iam::123456789012:role/WebIdentityRole',
  webIdentityTokenFile: '/path/to/token'
});

FromCognitoIdentity

This feature allows you to create a token provider that retrieves tokens from Amazon Cognito Identity. The code sample demonstrates how to configure the Cognito identity token provider with a specific identity pool ID and logins.

const { fromCognitoIdentity } = require('@aws-sdk/token-providers');
const cognitoIdentityProvider = fromCognitoIdentity({
  identityPoolId: 'us-west-2:example-pool-id',
  logins: {
    'cognito-idp.us-west-2.amazonaws.com/us-west-2_example': 'example-token'
  }
});

The 'aws-sdk' package is the official AWS SDK for JavaScript, which includes a wide range of services and features for interacting with AWS. It provides comprehensive support for AWS services, including token management, but it is a larger package compared to @aws-sdk/token-providers, which is more focused on token providers.

aws-amplify

The 'aws-amplify' package is a JavaScript library for frontend and mobile developers building cloud-enabled applications. It includes support for authentication, including token management with Amazon Cognito. While it offers similar functionalities, it is more geared towards frontend development and user authentication flows.

aws-cdk

The 'aws-cdk' package is the AWS Cloud Development Kit, which allows developers to define cloud infrastructure using code. It includes support for managing authentication and authorization tokens as part of infrastructure as code. However, it is primarily focused on infrastructure management rather than just token providers.
