Tips for preserving shopping cart in Angular?

As I delve into Angular, my goal is to create a straightforward ecommerce platform that allows users to add items to their cart, view them, and complete a checkout process.

To accomplish this, I have set up three components: the products list, cart, and checkout. Additionally, I have implemented a cart service to handle all cart-related operations, such as adding items, removing items, and calculating the total cost of the cart.

My main concern now is finding the most effective way to save the cart data when a user closes their browser and reopens it. Initially, the user's orders will be processed anonymously, without requiring any registration.

Should I stick with using local storage for now, and then transition to cookies once user registration is implemented? What would be the best strategy for ensuring a seamless experience for the user?

Answer №1

It is important to note that any data stored on the client side may be altered or deleted by the user. To ensure data integrity, consider storing the data temporarily in a database on the server and retrieving it when the app is relaunched or accessed from a different browser.

LocalStorage is preferred over SessionStorage as data stored in LocalStorage does not expire.

For example, a cart data service using LocalStorage can be found here: demo

SessionStorage, on the other hand, will be cleared once the page session ends.

A page session remains active as long as the browser is open, even through page reloads and restores.
