I'm unable to load images from the assets folder after deploy the angular app to firebase hosting. (build --prod) when run on localhost the images show. All other things are loading properly. this is my package json cli: ~6.2.0-beta.2 firebase-tools: 4.1.0

  }
}

tried at appComponent

<img src="../assets/image.jpg">
<img src="/assets/image.jpg">
<img src="assets/image.jpg">

none of this work.

hosting settings at firebase.json

"hosting": {
"public": "dist",
"ignore": [
  "firebase.json",
  "**/.*",
  "**/node_modules/**"
],
"rewrites": [
  {
    "source": "**",
    "destination": "/index.html"
  }
]

}

Are there some trick on the firebase? rewrites? someone can help me!

回答1:

Images loading now from assets in angular 6.1.3 after firebase deploy! Found the solution finally, well it works for me. The issue is the tsconfig.json change:

"outDir": "./dist/out-tsc",

to:

"outDir": "./dist",

回答2:

I also had the same issue. Here is the solution i tried

Open tsconfig.json change:

"outDir": "./dist/out-tsc",

to:

"outDir": "./dist"
Open angular.json. make sure assets configurations are as like below

       "assets": [
          "src/favicon.ico",
          "src/assets"
        ],

Change in img tag <br> src="/src/assets/img/pricing_comparison.PNG" to <br> src="/assets/img/pricing_comparison.PNG".

回答3:

I had the same problem with static assets after deploying to Firebase hosting, even though they worked fine when serving from localhost. I had to change from
<img src="/src/assets/img/pricing_comparison.PNG"> to
<img src="/assets/img/pricing_comparison.PNG">.

(p.s. I tried changing my tsconfig.json file according to the accepted answer, but this didn't change or resolve my error)

回答4:

If you're working in localhost

juste use url like

#login {
    background-image: url('/assets/app-assets/img/gallery/login-bg.jpg');
    background-size: 100% 100%;
    background-repeat: no-repeat;
  }

in your CSS or html component, this works for me. just change the image url from /src/assets/your_image.png to /assets/your_image.png
