Cart With the advent of HTML5, many sites were able to replace JavaScript plugin and codes with simple more efficient codes such as audio, video, geolocation, etc. HTML5 tags made the job of developers much easier while enhancing page load time and site performance. In particular, HTML5 web storage was a game changer as they allow users’ browsers to store user data without using a server. So the creation of web storage, allowed front-end developers to accomplish more on their website without knowing or using server-side coding or database. Cart

Online e-commerce websites predominantly use server-side languages such as PHP to store users’ data and pass them from one page to another. Using JavaScript back-end frameworks such as Node.js, we can achieve the same goal. However, in this tutorial, we’ll show you step by step how to build a shopping cart with HTML5 and some minor JavaScript code. Other uses of the techniques in this tutorial would be to store user preferences, the user’s favorite content, wish lists, and user settings like name and password on websites and native mobile apps without using a database.

Many high-traffic websites rely on complex techniques such as server clustering, DNS load balancers, client-side and server-side caching, distributed databases, and microservices to optimize performance and availability. Indeed, the major challenge for dynamic websites is to fetch data from a database and use a server-side language such as PHP to process them. However, remote database storage should be used only for essential website content, such as articles and user credentials. Features such as user preferences can be stored in the user’s browser, similar to cookies. Likewise, when you build a native mobile app, you can use HTML5 web storage in conjunction with a local database to increase the speed of your app. Thus, as front-end developers, we need to explore ways in which we can exploit the power of HTML5 web storage in our applications in the early stages of development.
