how to find my angular version in my project?

There are several ways you can do that:

1. Go into node_modules/@angular/core/package.json and check version field.

2. If you need to use it in your code, you can import it from the @angular/core:

   import { VERSION } from '@angular/core';

3. Inspect the rendered DOM – Angular adds the version to the main component element:

   <my-app ng-version="4.1.3">
