Inline the Web App Manifest?

问题

I have a marketplace/web application with thousands of static single page apps.

Wish to add a Web App Manifest for each single page app in the <head> </head> tag of their corresponding stem_url (The {root}/index.html for all the urls of a given SPA).

The standard method:

<link rel="manifest" href="/manifest.json">

…does not seem like a good way to go forward because this would mean thousands of manifest.js files being dumped into the /public folder (it's a rails app!) and it would eventually make the app/assets compilation job very heavy as this number goes up.

Is there a way we could inline manifest json just like we do the style tags:

<style>
  body { // style here }
  …
</style>

An equivalent of manifest declaration:

<manifest>
 { 
   "name": "HackerWeb",
   "short_name": "HackerWeb",
   …
}
</manifest>

You can inline the json by using a data:url. So instead of the standard

<link rel="manifest" href="/manifest.json">

it would be

<link rel="manifest" href='data:application/manifest+json,{ "name": "theName", "short_name": "shortName", "description": "theDescription"}' />

I wanted to inline it too and tried it just now. It works

The main thing to remember is that the manifest request is still just a network request.

So you can Add Query Params

/manifest.json?title=Hello&icon=.....

Or you could do:

/manifest.json?appId=1234

OR you can just use a pretty URL:

/manifest/1234

Then on your server you can return the JSON that you want.
