LocalStorage vs IndexedDB

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 meets developers should learn indexeddb when building progressive web apps (pwas) or any web application that requires robust offline capabilities, such as note-taking apps, document editors, or media players. Here's our take.

LocalStorage

Nice Pick

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

IndexedDB

Developers should learn IndexedDB when building progressive web apps (PWAs) or any web application that requires robust offline capabilities, such as note-taking apps, document editors, or media players

Pros

• It's essential for scenarios where users need to access and manipulate data without an internet connection, and for caching large datasets like product catalogs or user-generated content to reduce server load and latency
• Related to: javascript, progressive-web-apps

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. LocalStorage is a web-api while IndexedDB is a database. We picked LocalStorage based on overall popularity, but your choice depends on what you're building.

The Bottom Line

LocalStorage wins

Based on overall popularity. LocalStorage is more widely used, but IndexedDB excels in its own space.
