AWS SDK and Amazon Cognito Identity JS

Describe the bug It seems the amazon-cognito-identity-js library and AWS SDK are inconsistent. Please correct me if I’m wrong.

What I’m trying to do is just use the cognito-identity-js library appropriately through the AWS-SDK as documented:

    var poolData = {
        UserPoolId : '...', // Your user pool id here
        ClientId : '...' // Your client id here
    };
    var userPool = new AmazonCognitoIdentity.CognitoUserPool(poolData);

To Reproduce

const AWS = require('aws-sdk');
console.log(Object.keys(AWS)); //AmazonCognitoIdentity nor CognitoUserPool exist on this
const ci = AWS.CognitoIdentity
console.log(ci); //Nor on this
console.log(AWS.CognitoIdentityServiceProvider) //Nor on this.

Expected behavior Some way to access a user pool that is documented on the amazon-cognito-identity-js library.

Additional context I understand amplify is for client side apps. But most of us seem to have some need of cognito usage on the server side. It is taking tons of time to figure out.

You can turn on the debug mode to provide more info for us by setting window.LOG_LEVEL = ‘DEBUG’; in your app.

@elorzafe @undefobj thank you for confirming this approach. though it slightly worries me that the SDK returns a UserAttributes object array of Value, Key object pairs instead of an object as it seems strange and non-deterministic.

It’s confusing to have it return an array and so I’ve even implemented a check:

CognitoAdaptee.prototype.getEmail = async function(uuid) {
  const promise = CognitoService.adminGetUser({
    UserPoolId: USER_POOL_ID,
    Username: uuid
  }).promise();

  return promise
    .then(({UserAttributes}) => {
      const EMAIL_INDEX = 4;
      const email = UserAttributes[EMAIL_INDEX].Value
      logger.info(`Got email of user from Cognito Service: ${email}`)
      return email;
    })
    .then(email => {
      if (typeof email !== string) {
        throw new Error('Critical Gateway Error: UserAttributes are non deterministic in ordering');
      }
      return email;
    })
    .catch(e => {
      logger.error(`Error from CognitoAdaptee: ${JSON.stringify(e)}`)
      throw e;
    })
}

Though I believe this may be a separate issue for another repo such as aws-sdk-js

Otherwise, thank you again for your help. I’ve closed this issue.
