WebSQL vs Local Storage

Developers should learn WebSQL primarily for maintaining legacy web applications that still rely on it, as it was widely used in older browsers like Chrome and Safari 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.

WebSQL

Nice Pick

Developers should learn WebSQL primarily for maintaining legacy web applications that still rely on it, as it was widely used in older browsers like Chrome and Safari

Pros

• It's useful for understanding the evolution of client-side storage technologies and for scenarios requiring SQL-based querying in historical projects, but new development should avoid it due to lack of support and standardization
• Related to: indexeddb, sqlite

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. WebSQL is a database while Local Storage is a concept. We picked WebSQL based on overall popularity, but your choice depends on what you're building.

The Bottom Line

WebSQL wins

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