In web apps, it is often important to have a responsive design. Responsive design makes your web app render well on various devices and window/screen sizes. Our blog app might be viewed on a desktop, a mobile phone, a tablet, or maybe even a very large screen, such as a TV.
Often, it makes the most sense to simply use CSS media queries for responsive design. However, sometimes that is not possible, for example, when we render elements within a canvas or Web Graphics Library (WebGL). Sometimes, we also want to use the window size in order to decide whether to load a component or not, instead of simply rendering it and then hiding it via CSS later.
The @rehooks/window-size library provides the useWindowSize Hook, which returns the following values:
- innerWidth: Equal to the window.innerWidth value
- innerHeight: Equal to the window.innerHeight value
- outerWidth...
