Answer №1

If you encounter the following caution:

"environment.prod.ts" is included in TypeScript compilation but not utilized.
Ensure that only necessary entry points are specified in the 'files' or 'include' properties of your tsconfig.

within your component code:

import { environment } from 'src/environments/environment';
...
getProjects() {
// observable
if(!environment.production) {
    console.log(environment.apiUrl);
}
this.callback$ = this.apiService.get(environment.apiUrl);

in your environment.ts file:

export const environment = {
  production: false,
  apiUrl: 'https://abc.execute-api.us-west-2.amazonaws.com/prod/projects'
};

and in your environment.prod.ts file:

export const environment = {
  production: true,
  apiUrl: 'https://abc.execute-api.us-west-2.amazonaws.com/prod/projects'
};

Answer №2

Here is the command to use:

Replace '6.1.1' with the exact version number,

npm install -g @angular/<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="0b6867624b3d253a253a">[email protected]</a>

Answer №3

Don't forget to include the following in your tsconfig.app.json file:

"include": [
        "src/**/*.ts"
    ],
 "enableIvy": false
