CORS is Cross Origin Resource Sharing which means you can access a backend API through angularjs ($http) if CORS is enabled in backend.
You can instead use a server proxy like NodeJs to let frontend angular access the API.
AngularJS is designed to be a client-side application, meaning it renders in the client browser and does not run on the server. Therefore, you can't make a CORS request to an AngularJS frontend. CORS in AngularJS creates requests from the application for resources on other domains, typically with GET.
