In my React application, I am managing the state of a sidebar using the useState hook.
// sidebar toggled
const [sidebarToggled, setSidebarToggled] = useState(false);
When sidebarToggled is false, the sidebar is visible. When it is true, the sidebar is hidden.
To toggle the visibility of the sidebar, I have implemented a button with an onClick event handler.
<button onClick={()=>setSidebarToggled(!sidebarToggled)}>Toggle</button>
Desired Behavior:
I want the sidebar to be visible when the screen size is larger than 768px and hidden when it is smaller. This behavior should persist even if the screen size changes by resizing or minimizing/maximizing the window. To achieve this functionality, I wrote the following code snippet:
// toggle sidebar when screen reaches 768px
useEffect(() => {
const handleResize = () => {
if (window.innerWidth <= 768) {
setSidebarToggled(true);
}
else{
setSidebarToggled(false);
}
};
// Add event listener for window resize
window.addEventListener('resize', handleResize);
// Cleanup the event listener on component unmount
return () => window.removeEventListener('resize', handleResize);
}, []);
The Key Point:
If the user manually toggles the sidebar while on a device larger than 768px, I want that state change to be permanent regardless of any screen size adjustments. Similarly, if the sidebar is toggled on a mobile device, its visibility should not be affected by screen size changes.
