IndexedDB vs LocalStorage

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 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.

IndexedDB

Nice Pick

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

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

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

The Bottom Line

IndexedDB wins

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