IndexedDB vs Session Storage

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 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.

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

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

The Verdict

These tools serve different purposes. IndexedDB is a database while Session Storage is a concept. 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 Session Storage excels in its own space.
