gRPC-Web allows browser based applications to call into gRPC services via a special proxy. .NET developers are now able to build and consume services that use gRPC-Web using the Grpc.AspNetCore.Web NuGet package. In this episode, James Newton-King joins Cecil to explain how gRPC-Web works and show us what the code looks like to support this feature. [01:40] - What is gRPC about?
