Remove deep import of core.js 3

[akvaliya]

With angular 8 Ivy it prevents production build since it contains deep import.

Getting below error and build fails.
WARNING in Entry point 'ngx-restangular' contains deep imports into 'E:/test_app/node_modules/core-js/features/object'

Angular 9 Upgrade, same warning :
Warning: Entry point 'ngx-restangular' contains deep imports into 'C:/../node_modules/core-js/features/object'. This is probably not a problem, but may cause the compilation of entry points to be out of order.

And when i run my project
ERROR : Cannot instantiate cyclic dependency! Restangular

Maybe you can just silence the warning:

1. Create a file named 'ngcc.config.js' at your top-level project folder (see: #35683)

module.exports = {
    packages: {
        'ngx-restangular': {
        ignorableDeepImportMatchers: [
            /core-js\//,
        ]
        },
    },
};

2. Enjoy your build
