I am creating a PWA and stumbled upon a problem with the "start_url" in the manifest.json file. The website which I am trying to turn into a PWA depends on query params and "start_url":"/" doesn't pick up the query params.
I tried deleting the start_url from manifest.json and that seems to allow the app to be added to home screen (on iOS) but I guess on android the install prompt won't appear without the start_url?
Anyone has experienced a similar issue?
You can create a dynamic manifest just like this: https://stackoverflow.com/a/57856162/8716572
And then you can do something like "start_url": "your-url?query=" + queryValue.
<link rel="manifest" id="my-manifest-placeholder">
var myDynamicManifest = {
"name": "App name",
"short_name": "short",
"start_url": "your-url?query=" + queryValue
"background_color": "#000000",
"theme_color": "#0f4a73",
"icons": [{
"src": "icon.png",
"sizes": "512x5126",
"type": "image/png"
}]
}
const stringManifest = JSON.stringify(myDynamicManifest);
const blob = new Blob([stringManifest], {type: 'application/json'});
const manifestURL = URL.createObjectURL(blob);
document.querySelector('#my-manifest-placeholder').setAttribute('href', manifestURL);
var link = document.createElement('Link');
link.rel = "manifest";
link.setAttribute('href', 'data:application/json;charset=8' + stringManifest)
