Local Storage API vs Session Storage

Developers should use the Local Storage API when they need to persist small amounts of non-sensitive data, such as user preferences, form inputs, or application state, without requiring server-side storage meets developers should use session storage when they need to store temporary, session-specific data such as form inputs, shopping cart items, or user preferences that should not persist beyond the current browsing session. Here's our take.

Local Storage API

Session Storage

Developers should use Session Storage when they need to store temporary, session-specific data such as form inputs, shopping cart items, or user preferences that should not persist beyond the current browsing session

Pros

• It is particularly useful for single-page applications (SPAs) to maintain state during navigation without server requests, and for security-sensitive data that should be cleared when the session ends to prevent unauthorized access from other users on shared devices
• Related to: local-storage, cookies

Cons

• Specific tradeoffs depend on your use case
