Shopping Cart Html Password And MoreWhat you learn from this tutorial can easily be applied to other site features that may not require database storage such as user preferences, users favorite contents, wish list, user settings like username and password and more.![]() Update (27,29 Aug) Editors Note: We have updated the examples to address accessibility issues in the HTML. ![]() 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. 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. Shopping Cart Html How To Build AHowever, in this tutorial, well 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 users 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 users 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. I have been a part of a team developing a large-scale social website, and we used HTML5 web storage heavily. For instance, when a user logs in, we store the hashed user ID in an HTML5 session and use it to authenticate the user on protected pages. We also use this feature to store all new push notifications such as new chat messages, website messages, and new feeds and pass them from one page to another. When a social website gets high traffic, total reliance on the server for load balancing might not work, so you have to identify tasks and data that can be handled by the users browser instead of your servers. Project Background A shopping cart allows a websites visitor to view product pages and add items to their basket. The visitor can review all of their items and update their basket (such as to add or remove items). To achieve this, the website needs to store the visitors data and pass them from one page to another, until the visitor goes to the checkout page and makes a purchase. Storing data can be done via a server-side language or a client-side one.
