Alternatively, you can create a simple server using the following code:
gRPC is a remote procedure call (RPC) framework developed by Google. It allows developers to define service interfaces in a .proto file, which is then used to generate client and server code in various programming languages. gRPC uses Protocol Buffers (protobuf) as the interface definition language (IDL) and supports multiple transport protocols, including HTTP/2, TCP, and UDP.
Let’s create a simple .proto file that defines a Greeter service:
Now that we have our client code, let’s implement a simple gRPC client that uses the Greeter service:
