The manifest and the favicon are dependent on the light/darkmode is there any way of changing them as the user changes the mode in the operating system?
Ive got the event listener firing
window.matchMedia('(prefers-color-scheme: dark)').addEventListener( "change", (e) => {
if (e.matches) console.log('your in dark mode);
});
but the manifest is loaded from the react public folder..
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8" />
<link rel="shortcut icon" href="%PUBLIC_URL%/favicon.ico" />
<meta name="viewport" content="width=device-width, initial-scale=1" />
<meta name="theme-color" content="#000000" />
<meta
name="description"
content="Web site created using create-react-app"
/>
<link rel="apple-touch-icon" href="logo192.png" />
<link rel="manifest" href="%PUBLIC_URL%/manifest.json" />
<title>My Site</title>
</head>
<body>
<noscript>Please enable JavaScript to run this app.</noscript>
<div id="root"></div>
</body>
</html>
Not sure how to handle the favicon that is also in the root of the public folder. Also the meta tag for theme-color would need to change.
Using the suggestion from @kishore I've managed to get the favicon working, I'm sure someone better can tighten up my code but it works, in the html I added an id...
<link rel="shortcut icon" id='favicon' href="%PUBLIC_URL%/favicon.ico" />
<link rel="manifest" id='manifest' href="%PUBLIC_URL%/manifest.json" />
then in the head section I added...
<script>
const usesDarkMode = window.matchMedia('(prefers-color-scheme: dark)').matches;
const favicon = document.getElementById('favicon');
const manifest = document.getElementById('manifest');
function switchIcon(usesDarkMode) {
if (usesDarkMode) {
favicon.href = '%PUBLIC_URL%/favicon-dark.ico';
manifest.href='%PUBLIC_URL%/manifest-dark.json'
} else {
favicon.href = '%PUBLIC_URL%/favicon-light.ico';
manifest.href='%PUBLIC_URL%/manifest-light.json'
}
}
window.matchMedia('(prefers-color-scheme: dark)').addEventListener( "change", (e) => switchIcon(e.matches));
switchIcon(usesDarkMode);
</script>
