AWS SDK for JavaScript Cognito Identity Provider Client for Node.js, Browser and React Native
@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.
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: 'user@example.com'
}
]
};
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();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 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 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.

Using the Amazon Cognito User Pools API, you can create a user pool to manage directories and users. You can authenticate a user to obtain tokens related to user identity and access policies.
This API reference provides information about user pools in Amazon Cognito User Pools.
For more information, see the Amazon Cognito Documentation.
To install the this package, simply type add or install @aws-sdk/client-cognito-identity-provider using your favorite package manager:
npm install @aws-sdk/client-cognito-identity-provideryarn add @aws-sdk/client-cognito-identity-providerpnpm add @aws-sdk/client-cognito-identity-providerThe AWS SDK is modulized by clients and commands.
To send a request, you only need to import the CognitoIdentityProviderClient and
the commands you need, for example AddCustomAttributesCommand:
// ES5 example
const {
CognitoIdentityProviderClient,
AddCustomAttributesCommand,
} = require("@aws-sdk/client-cognito-identity-provider");
// ES6+ example
import { CognitoIdentityProviderClient, AddCustomAttributesCommand } from "@aws-sdk/client-cognito-identity-provider";
To send a request, you:
send operation on client with command object as input.destroy() to close open connections.// a client can be shared by difference commands.
const client = new CognitoIdentityProviderClient({ region: "REGION" });
const params = {
/** input parameters */
};
const command = new AddCustomAttributesCommand(params);
We recommend using await operator to wait for the promise returned by send operation as follows:
// async/await.
try {
const data = await client.send(command);
// process data.
} catch (error) {
// error handling.
} finally {
// finally.
}
Async-await is clean, concise, intuitive, easy to debug and has better error handling as compared to using Promise chains or callbacks.
You can also use Promise chaining to execute send operation.
client.send(command).then(
(data) => {
// process data.
},
(error) => {
// error handling.
}
);
Promises can also be called using .catch() and .finally() as follows:
client
.send(command)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
})
.finally(() => {
// finally.
});
We do not recommend using callbacks because of callback hell, but they are supported by the send operation.
// callbacks.
client.send(command, (err, data) => {
// proccess err and data.
});
The client can also send requests using v2 compatible style. However, it results in a bigger bundle size and may be dropped in next major version. More details in the blog post on modular packages in AWS SDK for JavaScript
import * as AWS from "@aws-sdk/client-cognito-identity-provider";
const client = new AWS.CognitoIdentityProvider({ region: "REGION" });
// async/await.
try {
const data = client.addCustomAttributes(params);
// process data.
} catch (error) {
// error handling.
}
// Promises.
client
.addCustomAttributes(params)
.then((data) => {
// process data.
})
.catch((error) => {
// error handling.
});
// callbacks.
client.addCustomAttributes(params, (err, data) => {
// proccess err and data.
});
When the service returns an exception, the error will include the exception information, as well as response metadata (e.g. request id).
try {
const data = await client.send(command);
// process data.
} catch (error) {
const { requestId, cfId, extendedRequestId } = error.$metadata;
console.log({ requestId, cfId, extendedRequestId });
/**
* The keys within exceptions are also parsed.
* You can access them by specifying exception names:
* if (error.name === 'SomeServiceException') {
* const value = error.specialKeyInException;
* }
*/
}
