Create Different AWS Cognito user pools, roles according to tenant with NestJS/Node.js

Question

I am developing a multi tenant application using NestJS (Node.js) and react. I am looking to store my users in the AWS Cognito user pool. I need to keep my users in different user pools according to their tenants.And need to create roles according to their tenants. I did not able to find a way to create user pools, roles and users through the Node.js (NestJS) or react. I did not find any helpful way to do that. Can some one advice me how to create different user pools through the program.(Is it possible??)

I followed some tutorials but I am not able to find a proper solution. And authorisation is and authentication looks fine. But I need to keep my users in different user groups according to their tenants.

Yes, we can do this programmatically. AWS Cognito user pools APIs facilitate this. For an example we can use CreateUserPool endpoint, to create a new user pool.

For Node.js, you can rely on AWS JavaScript SDK, which simplifies the usage of above APIs even more.

You have to use CognitoIdentityProviderClient and send a CreateUserPoolCommand with relevant parameters.

Following code block illustrate the high-level approach.

//Initiates the client with configs.
const client = new CognitoIdentityProviderClient({
    region: "REGION"
});

//setup input params for CreateUserPoolCommandInput
const params = {
    PoolName: "the-name-of-the-pool",
    EmailVerificationMessage: "message goes here."
    //add rest of the details as required.
};

//Initiate the command with input parameters.
const command = new CreateUserPoolCommand(params);

//Call send operation on client with command object as input.
const data = await client.send(command);
