Project planning is always signified as planning for the future, which means that a project should be planned, as it can be extended easily or can be reusable, more modular, and even scalable. For this project, we will design the application architecture in a realistic manner, so the user registration, login, and logout application can also be easily used in our future projects.
We will design the Application Programming Interface (API) and build the application using that API. The API will facilitate the application for any sort of user signup or signin related tasks, so that the core of the project is the API. Once we have the API ready, we can easily build a number of applications using that API.
First of all, let's think about the API design. Remember that we will use some architectural pattern, that is the Data Access Object (DAO) pattern for our projects.
