Feature Detection vs Modernizr

Developers should use feature detection to build cross-browser compatible web applications, especially when implementing modern web standards or experimental features that may not be universally supported meets developers should use modernizr when building websites that need to support a wide range of browsers, especially when using modern web technologies like css grid, flexbox, or es6+ javascript features. Here's our take.

Feature Detection

Nice Pick

Developers should use feature detection to build cross-browser compatible web applications, especially when implementing modern web standards or experimental features that may not be universally supported

Pros

• It is crucial for progressive enhancement, where basic functionality works across all browsers, and advanced features are added for those that support them, improving user experience without breaking the site
• Related to: progressive-enhancement, graceful-degradation

Cons

• Specific tradeoffs depend on your use case

Modernizr

Developers should use Modernizr when building websites that need to support a wide range of browsers, especially when using modern web technologies like CSS Grid, Flexbox, or ES6+ JavaScript features

Pros

• It's essential for creating cross-browser compatible applications without relying on user-agent sniffing, as it provides a reliable way to detect feature support and implement polyfills or graceful degradation
• Related to: javascript, html5

Cons

• Specific tradeoffs depend on your use case

The Verdict

These tools serve different purposes. Feature Detection is a concept while Modernizr is a tool. We picked Feature Detection based on overall popularity, but your choice depends on what you're building.

The Bottom Line

Feature Detection wins
