Cross-domain request in SPFx
How can I make a cross-domain request in a Client Side Web Part built with the SharePoint Framework? My need is to access SharePoint 2016 data from a SharePoint 2016 site in another domain (same credentials).
I found a crossDomainWeb method in the documentation for the add-in model, but nothing for SPFx.
Christophe Humbert SharePoint 2016 doesn't provide an easy way to configure CORS to allow for cross-domain calls. Easiest way in my experience is to create a custom Web API to perform and expose the SharePoint operations required and host it in the domain where your SPFx components reside.
You can use the Dev PnP JS library in SPFx to make cross-site collection calls.
The setup is very straight forward and will help you with other complex REST API calls as well.https://pnp.github.io/pnpjs/documentation/getting-started/
