On the back end OAuth Configuration the single-page applications are created with the assistance of Spring Boot and Spring Security. Each of the front ends makes use of jQuery, which is the same across all of them. The implementation of server-side rendering or migrating to a new JavaScript framework, on the other hand, would require just modest adjustments to be made.

OAuth 2.0 is supported in its native form in each of the examples provided by Spring Boot.

Each subsequent example expands upon the prior one and includes progressively more characteristics as it progresses:

A straightforward application consisting of the app's home page and the OAuth 2.0 setup settings required by Spring Boot for unconditional login (if you visit the home page, you will be automatically redirected to GitHub).

In addition, a logout option has been included for those who have already been authenticated.

Adds a second login provider, giving users the option to choose which one to use on the home page of the website.

You can use the app's source code to keep track of the modifications that need to be made to go from one app to the next on the feature ladder. There is a distinct directory for each version of the program, which allows you to compare and contrast the various iterations of the software.

Copying the files onto your hard drive can be done by entering the following command:

This is due to the fact that all of the applications utilize OAuth 2.0 clients that have been registered with GitHub and Google for localhost:8080. In order for your applications to work effectively, you will need to register them to run on a certain host or port. If you go with the standard settings, there is no chance that your credentials will be shared with anyone who is not part of your local network. It is important to exercise caution with any information you disclose online, and you should make every effort to avoid putting your personal app registrations in a public repository.

Single Create a user profile on GitHub.

During this stage, a straightforward app that relies on GitHub for authentication will be developed. Using the autoconfiguration features of Spring Boot will make this procedure extremely easy to complete.

Beginning Over from Square One

The first step is to create applications using Spring Boot. Getting started with Spring Boot is as easy as beginning a new project, which is the recommended method (choosing the "Web" dependency as a starting point). Perform this action using the command line equivalent:

It is now possible to navigate to the root directory of Ui using the command line as it has recently been constructed. tgz https://start.spring.io/starter.tgz | tar -xzvf -COPY -d style=web -d name=simple |

By default, a Java project will be generated for you; you can then choose to import it into the integrated development environment (IDE) of your choice, or you may just work with the files and mvn on the command line.
