How to use cors npm package?

Question

Angular

I make a request to google through angular $http, it gives an error

XMLHttpRequest cannot load http://maps.googleapis.com/maps/api/geocode/json?address=%D0%94%D0%BE%D1%81&sensor=false. Request header field Authorization is not allowed by Access-Control-Allow-Headers in preflight response.

I found such a package cors , they write that it will help if you add the code app.use('cors());
. There is no effect.
What to do ? Why does not it work?

Answer 1

cors is a middleware for express, a library running on the server, and has nothing to do with angular (running on the client).
