Can I dynamically modify start_url in the manifest.json file?

Question

Manifest., I want to modify the start_url of the json file after the page is loaded. This is because our app's start_url is different for each user. Because the parameters are different for each user, we need to load start_url dynamically I do not know how to fix it dynamically.

Is there any way to do this? Could it be possible when ServiceWorker is installed?

Answer 1

I solved a similar problem by using a url for a php file instead of a json file.

<link rel="manifest" href="/manifest.php?start_url=val">

The php file returns a json and when generating the page my server populates the url parameters dynamically. Everything working perfectly...

Suppose you have 3 categories. Make three .json files with respective scopes. Let's say japanese.json, black.json, voyeur.json

    $currentpage =$_SERVER['REQUEST_URI'];
    if ($currentpage == "/japanese") {
    $this->output('<link rel="manifest" href="/japanese.json">');}
    if ($currentpage == "/black") {
    $this->output('<link rel="manifest" href="/black.json">');}
    if ($currentpage == "/voyeur") {
    $this->output('<link rel="manifest" href="/voyeur.json">');}

You can also modify if you have a bunch of categories or the url structures are more complex.
