gRPC uses protocol buffers as the format for sending and recievind data.
Rest uses json likewise SOAP uses XML.
Initialize a new go project -go mod init github.com/rohitv5/grpc_golang_basic
To use protobuf with golang we need to install -go get -u google.golang.org/protobuf
-go get -u google.golang.org/grpc
Command to generate go files from proto
https://developers.google.com/protocol-buffers/docs/gotutorial
1.copy the protoc file win64 version from the link https://github.com/protocolbuffers/protobuf/releases 2.Extract the contents of the zip file. 3.Bin directory contains the protoc.exe 4.Update the environment variable to point to the bin directory that contains the protoc.exe 5.Re-Open the cmd as the environment variable take effect only on new command window 6.run=> protoc --go_out=. --go-grpc_out=. chat.proto // . means the folder will be current folder plus whatver is the option in proto file.
Apps installed by go command are present in C:\Users\verma\go\bin. Add this to path.

//next task is to expose an endpoint in client and pass data over it. which passes data to grpc service.
