@aws-sdk/client-cognito-identity-provider

What is @aws-sdk/client-cognito-identity-provider?

@aws-sdk/client-cognito-identity-provider is a part of the AWS SDK for JavaScript. It allows developers to interact with Amazon Cognito, a service that provides user sign-up, sign-in, and access control. This package enables you to manage user pools, authenticate users, and handle user data securely.

What are @aws-sdk/client-cognito-identity-provider's main functionalities?

User Sign-Up

This feature allows you to register a new user in a Cognito User Pool. The code sample demonstrates how to use the SignUpCommand to create a new user with specified attributes.

const { CognitoIdentityProviderClient, SignUpCommand } = require('@aws-sdk/client-cognito-identity-provider');

const client = new CognitoIdentityProviderClient({ region: 'us-west-2' });

const signUp = async () => {
  const params = {
    ClientId: 'your-client-id',
    Username: 'username',
    Password: 'password',
    UserAttributes: [
      {
        Name: 'email',
        Value: '[e-mail]'
      }
    ]
  };
  const command = new SignUpCommand(params);
  try {
    const data = await client.send(command);
    console.log('Sign-Up successful:', data);
  } catch (error) {
    console.error('Error during sign-up:', error);
  }
};

signUp();

User Authentication

This feature allows you to authenticate a user using their username and password. The code sample demonstrates how to use the InitiateAuthCommand to authenticate a user and retrieve authentication tokens.

const { CognitoIdentityProviderClient, InitiateAuthCommand } = require('@aws-sdk/client-cognito-identity-provider');

const client = new CognitoIdentityProviderClient({ region: 'us-west-2' });

const authenticateUser = async () => {
  const params = {
    AuthFlow: 'USER_PASSWORD_AUTH',
    ClientId: 'your-client-id',
    AuthParameters: {
      USERNAME: 'username',
      PASSWORD: 'password'
    }
  };
  const command = new InitiateAuthCommand(params);
  try {
    const data = await client.send(command);
    console.log('Authentication successful:', data);
  } catch (error) {
    console.error('Error during authentication:', error);
  }
};

authenticateUser();

Password Reset

This feature allows you to initiate a password reset for a user. The code sample demonstrates how to use the ForgotPasswordCommand to start the password reset process, which sends a verification code to the user's email or phone.

const { CognitoIdentityProviderClient, ForgotPasswordCommand } = require('@aws-sdk/client-cognito-identity-provider');

const client = new CognitoIdentityProviderClient({ region: 'us-west-2' });

const resetPassword = async () => {
  const params = {
    ClientId: 'your-client-id',
    Username: 'username'
  };
  const command = new ForgotPasswordCommand(params);
  try {
    const data = await client.send(command);
    console.log('Password reset initiated:', data);
  } catch (error) {
    console.error('Error during password reset:', error);
  }
};

resetPassword();

Other packages similar to @aws-sdk/client-cognito-identity-provider

amazon-cognito-identity-js

The amazon-cognito-identity-js package is a JavaScript library for Amazon Cognito. It provides similar functionalities to @aws-sdk/client-cognito-identity-provider, such as user sign-up, sign-in, and password management. However, it is more focused on client-side applications and provides a higher-level abstraction for interacting with Cognito.

cognito-express

cognito-express is a middleware for Express.js that simplifies the process of verifying Amazon Cognito JWT tokens. It is useful for server-side applications that need to authenticate and authorize users based on their Cognito tokens. Unlike @aws-sdk/client-cognito-identity-provider, it does not provide user management functionalities.

aws-amplify

AWS Amplify is a comprehensive library that provides a set of tools and services for building cloud-enabled applications. It includes support for Amazon Cognito for authentication and user management, along with other AWS services. AWS Amplify offers a higher-level abstraction and is designed to simplify the integration of various AWS services into your application.
