how to use angular 5 to build chrome extension

I am trying to build a chrome extension using angular 5. I created a basic angular app using Angular Material and it worked great as an angular app (I used ng build to check). I tried to move the application to be a chrome extension so I used ng build to create the code and I added the following manifest

{
   "name": "Getting Started Example",
   "version": "1.0",
   "description": "Build an Extension!",
   "background": {
      "scripts": ["runtime.js","polyfills.js","styles.js","vendor.js","main.js"],
      "persistent": false
    },
    "page_action": {
       "default_popup": "index.html"
     },
    "manifest_version": 2
}

the background scripts are the scripts the angular compiler created and are used to render the app. I upload my extension but I got this error

Uncaught EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self' blob: filesystem: chrome-extension-resource:".

what does it mean? how can I run my angular application as a chrome extension?

You need to add this line to the manifest.json for that error to go away:

 "content_security_policy": "script-src 'self' 'unsafe-eval'; object-src 'self'"

and remove the following line of code, because that isn't needed:

"scripts": ["runtime.js","polyfills.js","styles.js","vendor.js","main.js"]

To setup a proper workflow is a different story. Every time you make a change you need to rebuild the project manually. This can be some what of a hassle.

I have created a CLI to support such a workflow (auto watch files, build for production and zip it etc)

see: https://github.com/larscom/ng-chrome-extension for more information.

You no need to add JS files in the script just add reffernce of index.html file of your dist folder It will automatically add all required JS/CSS files from there.

so Just remove this line of code

"scripts": ["runtime.js","polyfills.js","styles.js","vendor.js","main.js"],
