Manifest: Is it possible for a progressive web app to embed web manifest into html page?

[svdoever]

I would like to have a link to the manifest file in my index.html by embedding it as below, but seams not to be supported. I there a possibility to embed the manifest description in the web page?

<link rel="manifest" href="data:application/manifest+json;base64,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">

@svdoever Can you explain the use case for something like this?

[marcoscaceres]

@svdoever, that should absolutely work. Sounds like a bug in Chrome.

[svdoever]

@RobDolinMS See also issue https://github.com/w3c/manifest/issues/535. My case is that I want to use a SharePoint document library to host my PWA, so I can execute my PWA in the context of a SharePoint site. See also my blogpost series at http://weblogs.asp.net/soever. On the request for the manifest the authentication cookie is not passed along on the request, so it can't read it from SharePoint. If I could embed during my build process of my main page I could solve this, but that isn't supported either it seems. I could only solve it by placing the manifest in a public place (my dropbox), with absolute link for the start_url. Not ideal. I also wonder if the lighthouse tool in chrome will work when the data could be embedded in the href.

What is the best place to report these issues with chrome?

[marcoscaceres]

Fwiw, we discussed this use case when we first started working on the spec. The solution showed here is supposed to work per spec.

[svdoever]

When requesting the home page of the app it shows the request link, but can't show info:

The request headers of index.aspx (and all other loaded artifacts like images) show the cookie with authentication information:

The link request to the manifest does not have the cookie with authentication information in the request header:

In @svdoever's comment:

On the request for the manifest the authentication cookie is not passed along on the request, so [the browser] can't read [the manifest] from SharePoint

I found this link: https://support.google.com/chrome/answer/95315?hl=en but @mounirlamouri or @jakearchibald may be able to suggest a good place to report the bug you found in the way Chrome fetches web app manifests.

@RobDolinMS thanks for the link, i will report it there. In the mean time saved me to load the manifest from a site with authentication.

@svdoever can we close this issue?
