I'm trying to figure out how to setup site custom fields, to be retrieved from React webparts.
Doing some research, I've found several articles talking about Property Bags, like this one which seems satisfying my needs, but my question is: supposing to setup a property bag for a site (PowerShell is the only way?), is then retrievable by webparts deployed on that site?
Could you please give me an example/link, on how to retrieve this information in a React Webpart?
Thanks in advance.
