AWS Cognito with React JS (Session and Logout) – Part 4

Voiced by Amazon Polly


In my previous blog, we learned how to verify the user in the Cognito user pool and how to log in the user in our application using ‘amazon-cognito-identity-js’. In this blog, we will learn how to manage the state or session of a logged-in user and how to log out the user from the application using the ‘amazon-cognito-identity-js’ library.

Introduction to 'amazon-cognito-identity-js'

‘amazon-cognito-identity-js’ is the SDK that allows a JavaScript-enabled application to authenticate the users, view user details, delete users, update users and register the users. It also allows password change for authenticated users and forgot password functionality.

Steps to Create a Component

Step 1: Create an Account.js file in src/Components directory and follow the code snippet in the file.

 This code snippet is for Central session management. We can use it in every component. In this component, we will get the current session information using getCurrentUser method in getSession function. And in authenticating function, we will authenticate the user. And Logout function is to log out the user from the application.

Step 2: Create a ‘Status.js’ file in src/components directory

This code snippet is to get the user’s current session using the getSession function which we created in the last step. And on the UI, we are displaying the current status of the user using HTML code.

Step 3: Modify the App.js

 This code snippet is for wrapping the whole application with the Account component to use all the function of the Account component in every component of the application.

<Status /> is to display the current stage of the user whether it is logged in or not.

Step 4: Modify the Login.js file

In this step, we are modifying the login page and will call authenticate method of the Account component to log in.


In this blog, we learn how to manage the state or session of logged in users and how to log out the user from the application using the ‘amazon-cognito-identity-js’ library.
