Usage:

At the main HTML file, add teh following script tag:

<script> window.global = window; </script>

Otherwise, the library might not work as expected.

// Instantiate a cognitoAuth object:
const auth = new CognitoAuth();

// User attributes for sign in.
const username = "[email protected]";
const password = "Password1!";
const attributes = [{ Name: "email", Value: username }];

// Response handler
const handler = (error?: Error, result?: unknown) => {
  if (error) console.error(error);
  else if (result) console.log(JSON.stringify(result));
}

// Register a new user:
auth.SignUp(
  username,
  password,
  attributes,
  handler
);

// Enable automatic sign in using:
auth.CachedSignIn(handler);

// Manual sign in
auth.SignIn(username, password, handler);

// Sign out invalidating user's token (recommended)
auth.SignOut(true, handler);
