IndexedDB vs Local 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 local storage for client-side data that needs to persist between sessions, such as user preferences, form data, or application state in single-page applications. 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

Local Storage

Developers should use Local Storage for client-side data that needs to persist between sessions, such as user preferences, form data, or application state in single-page applications

Pros

• It's ideal for non-sensitive data due to its accessibility via JavaScript and lack of built-in security features, making it unsuitable for storing passwords or personal information
• Related to: session-storage, cookies

Cons

• Specific tradeoffs depend on your use case

The Verdict

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