🕵️ safe-feature-detect

A lightweight and extendable feature detection library heavily inspired by the great Feature.js. Like Feature.js, this library stays under 1kb minified & gzipped. In addition, safe-feature-detect caches detections and will not throw an error if for some reason it's called during server side rendering.

Installation

npm install safe-feature-detect

      return false;
    }
  });
