Saving Shopping Cart Lists with a Java Spring Boot Angular App using localStorage
In this article, we will discuss how to create a shopping cart list application using Java Spring Boot, Angular, and MySQL. We will focus on how to save the shopping cart list in the user's local storage, perform price and quantity calculations directly, and cover the key concepts, applications, and significance of this approach.
Key Concepts
The key concepts of this approach include using local storage to save the shopping cart list, performing price and quantity calculations directly, and using Java Spring Boot and Angular to build the application.
Local Storage
Local storage is a web storage object that stores data with no expiration date. The data will not be deleted when the browser is closed, and it can be accessed on future visits. Local storage is useful for saving user preferences, form data, and shopping cart lists.
localStorage.setItem("key", "value") is used to save data in local storage, and localStorage.getItem("key") is used to retrieve data from local storage.
Price and Quantity Calculations
Price and quantity calculations can be performed directly in the application without the need for a server-side calculation. This approach reduces the amount of data that needs to be sent between the client and the server, improving the performance of the application.
Java Spring Boot and Angular
Java Spring Boot is a Java-based framework used to build web applications. It provides a fast and efficient way to build applications, and it includes many features such as security, data access, and web services.
Angular is a JavaScript framework used to build web applications. It provides a powerful and flexible way to build dynamic and responsive applications. Angular includes many features such as data binding, directives, and dependency injection.
Applications
This approach can be used in any application that requires a shopping cart list, such as e-commerce websites, online marketplaces, and food delivery apps. By saving the shopping cart list in local storage, users can continue shopping even if they close their browser or lose their internet connection.
Significance
Saving the shopping cart list in local storage has several benefits. It improves the performance of the application by reducing the amount of data that needs to be sent between the client and the server. It also provides a better user experience by allowing users to continue shopping even if they lose their internet connection.
