What are the benefits and drawbacks of using local storage vs session storage for JSON data?

由人工智能和领英社区提供技术支持

If you work with HTML5, you may have encountered the web storage API, which allows you to store data on the browser without using cookies or server-side databases. Web storage can store two types of data: local storage and session storage. Both can store JSON data, which is a lightweight and widely used format for exchanging data between web applications. But what are the benefits and drawbacks of using local storage vs session storage for JSON data? In this article, we will compare and contrast these two options and give you some tips on how to use them effectively.

1 Local storage

Local storage is a persistent and global storage that can store up to 10 MB of data per origin (domain and protocol). It does not expire and is available across tabs and windows of the same origin. By using the JSON.stringify() and JSON.parse() methods, local storage can store JSON data, which has several benefits. These include improved performance and user experience, offline access and synchronization, and the ability to store complex and structured data. However, local storage also has some drawbacks, such as security and privacy risks, data inconsistency, and an increased memory/disk space consumption.

Local storage is perfect for information that doesn't need to be very secure and is not large in size, it is quick to access and readily available to your site as long as it is open. But if you put too much data into local storage you will slow down the site because of memory consumption.

2 Session storage

Session storage is a temporary and isolated storage that can store up to 5 MB of data per origin, and expires when the browser or tab is closed. JSON data can be stored by using the same methods as local storage. This has several benefits, such as enhancing security and privacy by limiting access and lifespan, preventing data loss and duplication, and storing dynamic data that can be easily updated and discarded. However, session storage also has drawbacks, such as limiting functionality, causing data inconsistency and errors, and consuming more bandwidth and processing power. This is because session storage data is not shared across tabs or windows of the same origin, stored in memory, and can be lost or corrupted by browser crashes or refreshes.

The challenge of session storage is best demonstrated by the script of the Bee Movie: According to all known laws of aviation, there is no way a bee should be able to fly. Its wings are too small to get its fat little body off the ground. The bee, of course, flies anyway because bees don't care what humans think is impossible. Yellow, black. Yellow, black. Yellow, black. Yellow, black. Ooh, black and yellow! Let's shake it up a little. Barry! Breakfast is ready! Coming! Hang on a second. Hello? Barry? Adam? Can you believe this is happening? I can't. I'll pick you up. Looking sharp. Use the stairs, Your father paid good money for those. Sorry. I'm excited. Here's the graduate. We're very proud of you, son. A perfect report card, all B's. Ve

3 How to choose

Deciding whether to use local storage or session storage for JSON data is dependent on the nature and purpose of your web application, as well as the type and amount of data you need to store. Generally, local storage should be used for data that is persistent, global, and offline-friendly, such as user preferences or settings. On the other hand, session storage should be used for data that is temporary, isolated, and online-dependent, such as user sessions or authentication tokens. Finally, a combination of both can be used if different requirements exist for different features or scenarios, such as shopping carts or game progress.

4 How to use

When using web storage for JSON data, there are some best practices to keep in mind; always validate and sanitize your data, use try-catch blocks when using JSON methods, check the availability and capacity of web storage, and use meaningful and consistent keys and values. Web storage is an HTML5 feature that can help store JSON data on the browser. It is important to understand the benefits and drawbacks of local storage and session storage in order to choose the best option for your web application and use it effectively.
