GRPC-Web

gRPC-web allows you to use gRPC calls on the front-end. Normally, you would need to use an envoy proxy on the back-end, in order to make the gRPC calls compatible with HTTP2. However, on the SIP this is done for you. You will still need to use an envoy proxy if you want to test your application locally. To use gRPC-web on the SIP, you need to specify it in your sip.yml file. The relevant documentation can be found here: sip.yml (SIP Application Template).
