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?

    Right now that's the best answer I found. When I finish working on it I'll let you know: https://medium.com/@alshakero/how-to-setup-your-web-app-manifest-dynamically-using-javascript-f7fbee899a61 – gtamborero Nov 25 '18 at 21:45
  • Did you manage to find a solution for this? I've seen https://medium.com/@alshakero/how-to-setup-your-web-app-manifest-dynamically-using-javascript-f7fbee899a61 and it seems a bit dirty but maybe it is the only solution. – Royalsmed Mar 27 '19 at 21:22

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...

    Why is everyone giving answers involving PHP when the original question doesn't even mention PHP? – Michael Mar 06 '21 at 20:05

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.

  • First, the question asked for a different manifest PER USER. This would definitely be more than 3. Second, what is that, PHP? I didn't see anything about server side code in the question. – Michael Mar 06 '21 at 20:05
