Description

In this course you will learn to create a frontend application using HTML, CSS, JavaSCript and Bootstrap.

Then we will learn to create a Springboot application. After that, we will move on to create few REST API endpoints in our Springboot Application.

Next we will move on to configure google console dashbaord to register our Springboot application.

Then we will make a connection from our Springboot application with Google console.

After that we will configure Spring Security in our Springboot application in such a way that only allowed endpoints will not need authentication. But for other endpoints user will be redirected to Google Authentication page.

On Google Authentication page user will fill out its google credentials. If entered credentials are the correct user will be redricted to our Springboot Application.

Now its time for us to create our frontend application and we will connect this frontend with our Springboot application.

So user will now come to our Frontend, then he will login with google.

On successful login we will fetch user information from google and show it to user on the next page.

With Login with Google functionality we don’t have to keep a seperate user database with us rather we can ask google to authenticate our user on our application’s behalf. If successfully authenticated then google will give us all the profile information of the user.

Using this information we can do further operation in our application.
