Introduction

Overview

Auth.currentAuthenticatedUser({ 
bypassCache: true // Optional, By default is false. }).then((user) => {
user.deleteUser((error, data) => {
if (error) { throw error; }
// Do something to delete user data in your system // Log the user out
Auth.signOut({ global: true });
});
}).catch(err => console.log(err));

Assumptions & Getting Started

npm i @aws-sdk/client-cognito-identity-provider --save

Code

import Auth from '@aws-amplify/auth'; 
import {CognitoIdentityProvider} from '@aws-sdk/client-cognito-identity-provider';
import * as AWS from '@aws-sdk/client-cognito-identity-provider';
// We call currentAuthenticatedUser to get a current AccessToken Auth.currentAuthenticatedUser({ 
bypassCache: true // Optional, By default is false.
}).then((user) => {
// Create a new CognitoIdentityProvider object for your
// Cognito User Pool Region
const cognitoIdentityProvider = new CognitoIdentityProvider({region: 'us-west-2'});
// Create the required request parameter
var params = {
AccessToken: user.signInUserSession.accessToken.jwtToken
};

// Call the deleteUser function using a callback function
cognitoIdentityProvider.deleteUser(params, function(err, data)
{
if (err) { console.log(err); }

// Do something here to delete user data in your system
// Sign the user out globally
Auth.signOut({ global: true });
});
}).catch(err => console.log(err));
