Cache API vs Local Storage

Developers should learn the Cache API when building web applications that require offline capabilities, faster load times, or reduced network dependency, such as PWAs, single-page applications, or content-heavy sites 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.

Cache API

Nice Pick

Developers should learn the Cache API when building web applications that require offline capabilities, faster load times, or reduced network dependency, such as PWAs, single-page applications, or content-heavy sites

Pros

• It is particularly useful for caching static assets like HTML, CSS, JavaScript, and images to enhance user experience in low-connectivity scenarios
• Related to: service-workers, 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. Cache API is a platform while Local Storage is a concept. We picked Cache API based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Cache API wins

Based on overall popularity. Cache API is more widely used, but Local Storage excels in its own space.
