gRPC is a modern open-source high-performance Remote Procedure Call (RPC) framework that can run in any environment. An RPC is when one computer calls a procedure in another process or on another computer over a network as if it were calling a local procedure. It is an example of a client-server architecture.

On the client, a strongly typed gRPC client provides the same methods as on the server.
Defining gRPC contracts with .proto files
gRPC uses contract-first API development that supports language-agnostic implementations. A contract in this case is an agreement that...
