Different approaches for generating proto classes

Let’s examine the various languages for generating proto classes.

C++

protoc -I=$SRC_DIR --cpp_out=$DST_DIR $SRC_DIR/sfapi.proto

C

protoc -I=$SRC_DIR --csharp_out=$DST_DIR $SRC_DIR/sfapi.proto

GO

go get golang.org/x/sys/unix
go get -u github.com/golang/protobuf/protoc-gen-go

protoc -I=$SRC_DIR --go_out=$DST_DIR $SRC_DIR/sfapi.proto

Java

protoc -I=$SRC_DIR --java_out=$DST_DIR $SRC_DIR/sfapi.proto

Python

protoc -I=$SRC_DIR --python_out=$DST_DIR $SRC_DIR/sfapi.proto

NodeJS

On the fly class generation with protobuf.js:

const grpc = require('grpc')
const proto = grpc.load('./proto/sfapi.proto').sfapi.v1

And here are some advanced functionalities.

Option declarations

Option declarations may be declared to engage different behaviors when each language generates the code responsible for the interpretation of the .proto file.
