I am working on a simple web application with angular 5 that will take banking exchange rates and make calculation for the user in the currency that he requires. The banking site does not have cors enabled. Is there a way in PWA to side step the cors issue without making a proxy ?
For the get request I use http client from '@angular/common/http' library.
Below is a quote from Google PWA docs on Cross-domain/cross-origin request.
Custom headers on cross-origin requests must be supported by the server from which the resource is requested.
If your bank blocks the cross-origin requests, you can't do anything about it. They want to secure their resources only for their domain.
Hope it helps.
