While build Angular application getting warning message like as below:

WARNING in /Users/deb/Documents/ProjectName/src/app/services/filename.service.ts depends on 'rxjs/observable/dom/WebSocketSubject'. CommonJS or AMD dependencies can cause optimization bailouts. For more info see: https://angular.io/guide/build#configuring-commonjs-dependencies

"allowedCommonJsDependencies": [
            "lodash"
          ],

Even we follow angular guide line its still giving same warning message.

Angular version : 10.x

So how to fix it.

the dependency you would need to allow seems to be coming from rxjs and not lodash, so shouldn't you add rxjs or some subset of it to your allowedCommonJsDependencies? - tommueller

In the angular doc https://angular.io/guide/build#configuring-commonjs-dependencies

they have just shown to add your dependencies in allowedCommonJsDependencies[] in the options object of angular.json file

please see how i have added my dependencies "allowedCommonJsDependencies": [ "url-join", "lodash", "rxjs/add/observable/forkJoin", "date-fns", "@firebase/component", "@firebase/util", ],

my angular.json file

my suggest edit your code

"allowedCommonJsDependencies": [
   "rxjs/observable/dom/WebSocketSubject"
],
