'Check for Windowsize React component

What I am basically trying to create is a navbar that has two completely different html hierarchy based on the window size. I want it to be different for mobile than for a desktop version. eg a nav bar that is on the right on desktop and one that is on the top for mobile.

A simply state of what was doing. I created a const that would use a state of the screen size. I had used the useState() to get a default for now but I know that if I was first loading on desktop and it it was defaulted to mobile. I would have to resize first to get the desktop version instead.

const [sizeState, setSizeState] = useState("mobile");
const changeNavbar = () => {
    if (window.innerWidth <= 900) {
        setSizeState("mobile"); 
    } else {
        setSizeState("desktop"); 
    }
};

window.addEventListener('resize', changeNavbar);

the sizeState would then call an if function determin what state it curently is set to.

if (sizeState === "mobile") {
    return ( //some code for mobile) }
else {
// return some code for desktop
 }

for now it always returns the mobile version even if loading upon a innderwidth that is above 900 abd only on resize it would do something. I have been trying to use a onload stuff and an eventlistener that would listen to load. but i cant manage to call the changeNavbar function on the first load of the page.

I saw people recomending usein useMediaQuerry but i dont know how to get it to work based on my if (mediaquery is set to md) { return( mobile navbar) }

if someone could help me use the useMediaQuerry in this instead of my previous attempt, so that i can have two seperated returns i would also be soooooo thankful for the help!

  1. You can simply implement it using styled-components and styled-breakpoints packages and its hooks API.

  2. Or you can create custom hooks like this: https://codesandbox.io/s/react-hooks-usewindowsize-5ypkqr
