AWS, JavaScript, React - Deploy Web Apps on the Cloud - Introduction to Local Storage

The video tutorial addresses an issue with cart persistence in a checkout screen. It introduces the concept of local and session storage APIs, explaining their differences and how they can be used to improve user experience by maintaining cart data across page refreshes and browser sessions. The tutorial demonstrates how to implement these storage solutions in code, test their functionality, and switch from session to local storage for better persistence. The video concludes with a preview of the next lesson on implementing a basic search feature.

What issue does the teacher want to address before continuing with the checkout screen?

• Fixing cart data loss on refresh

• Improving the UI design

• Adding more payment options

• Enhancing security features

What is the main advantage of using local and session storage over cookies?

• They can store larger files

• They are faster to access

• They store data in the cloud

• They are more secure and streamlined

How does session storage differ from local storage?

• Local storage can only store JSON objects

• Local storage is cleared when the browser is closed

• Session storage persists data indefinitely

• Session storage is cleared when the tab or browser is closed

What is the first step in implementing session storage for cart items?

• Create a new database

• Add a line to store cart items in session storage

• Use cookies to store cart data

• Implement a new API for storage

What happens to session storage data when the browser is closed?

• It is transferred to local storage

• It is saved to the server

• It is encrypted

• It is removed

Why is local storage preferred over session storage for cart data persistence?

• It is faster to access

• It is easier to implement

• It persists data across browser sessions

• It uses less memory

What change is necessary to switch from session storage to local storage?

• Increase the storage capacity

• Change the API calls from session storage to local storage

• Encrypt the data

• Use a different key for storage

How can you verify that local storage is working correctly?

• By checking the server logs

• By refreshing the page multiple times

• By observing data persistence across tabs and browser sessions

• By using a debugger tool

What should be done to clear the cart data from local storage?

• Close the browser

• Use the localStorage.clear() method

• Refresh the page

• Open a new tab

What is the next feature to be implemented after local storage?

• A search facility

• A payment gateway

• A wishlist feature

• User authentication
