I have my app developed in StackBlitz, and incldued with ngx-translate package. It is working perfectly until it deployed to firebase.... basically everything broken (sobbing...) I tried my best to detail out my configs and the error log as i couldn't resolve it myself. I also dig through the internet but no luck to resolve any of them. Sorry for the lengthy post.

index.html

<link rel="stylesheet" type="text/css" href="/node_modules/primeicons/primeicons.css" />
<link rel="stylesheet" type="text/css" href="/node_modules/primeng/resources/themes/nova-light/theme.css" />
<link rel="stylesheet" type="text/css" href="/node_modules/primeng/resources/primeng.min.css" />

The above code error out in Firebase but not StackBlitz (run perfectly)

Resource interpreted as Stylesheet but transferred with MIME type text/html: "https://fireforgez.firebaseapp.com/node_modules/primeng/resources/themes/nova-light/theme.css".
Resource interpreted as Stylesheet but transferred with MIME type text/html: "https://fireforgez.firebaseapp.com/node_modules/primeng/resources/primeng.min.css".
Resource interpreted as Stylesheet but transferred with MIME type text/html: "https://fireforgez.firebaseapp.com/node_modules/primeicons/primeicons.css".

To get rid of it, i did a silly patch by replace it with actual web URL

<link rel="stylesheet" type="text/css" href="https://unpkg.com/primeicons@4.0.0-rc.2/primeicons.css" />
<link rel="stylesheet" type="text/css" href="https://unpkg.com/primeng@9.1.0/resources/themes/nova-light/theme.css" />
<link rel="stylesheet" type="text/css" href="https://unpkg.com/primeng@9.1.0/resources/primeng.min.css" />

PrimeFlex package also hit the similar error

    DevTools failed to load SourceMap: Could not parse content for
https://fireforgez.firebaseapp.com/primeflex.css.map: Unexpected token < in JSON at position 0

I compared both StackBlitz and Firebase, the stylesheet files are all load-able. But when i replace with firebase hosting url, all .css revert back to firebase main url e.g. https://fireforgez.firebaseapp.com/node_modules/primeng/resources/themes/nova-light/theme.css will redirect to https://fireforgez.firebaseapp.com/ and generated a series of error

For ngx-translate, it's also working correctly in StackBlitz but couldn't load language files.

I very appreciate Eric, who is the owner of StackBlitz being so grateful and patient to explained that the Firebase deployment still in Beta (i didn't aware before that!...) https://github.com/stackblitz/core/issues/1254#issuecomment-636860107

I keep trying every possible ways to solve it in SB for deployment but no luck. With his advise, i crack my head and bring down the project to local, and manually build the broken dependencies in local. After that i deployed to firebase and everything is now WORKING!

So for the time being, if you guys having serious projects and need to deploy from SB to Firebase, i advise you to wait until the deployment got a stable release.
