SessionStorage vs LocalStorage

Developers should use SessionStorage when they need to store temporary, client-side data that should be cleared when the browser tab or window is closed, such as saving form data to prevent loss on page refresh, managing user interface state (e meets developers should use localstorage when they need to persist non-sensitive user data like preferences, form drafts, or application state locally in the browser, particularly for progressive web apps (pwas) or offline functionality. Here's our take.

LocalStorage

Developers should use LocalStorage when they need to persist non-sensitive user data like preferences, form drafts, or application state locally in the browser, particularly for progressive web apps (PWAs) or offline functionality

Pros

• It's ideal for scenarios requiring simple client-side storage without complex setup, such as remembering user settings, caching small datasets, or maintaining session-like state across page reloads, but should be avoided for sensitive data due to lack of encryption and XSS vulnerabilities
• Related to: session-storage, indexeddb

Cons

• Specific tradeoffs depend on your use case

The Verdict

Use SessionStorage if: You want g and can live with specific tradeoffs depend on your use case.

Use LocalStorage if: You prioritize it's ideal for scenarios requiring simple client-side storage without complex setup, such as remembering user settings, caching small datasets, or maintaining session-like state across page reloads, but should be avoided for sensitive data due to lack of encryption and xss vulnerabilities over what SessionStorage offers.
