In this section we will create a money transaction service which will communicate over GRPC: Go get -u /golang/protobuf/protoc-gen-go (already did in the previous section)

Install them using the following commands: We need to install the grpc Go library and a protoc-gen plugin before writing the The main advantage of gRPC is that it can be understood by multiple programming languages (via their respective grpc packages mostly) making the communication easy between different tech stacks The two parties are referred to as server and client. GRPC is a transport mechanism that sends and receives messages (protocol buffers) between two systems. Using gRPC (Google Remote Procedure Call), a server and client(not frontend) can talk which each other in the protocol buffer format. This serialized binary data needs a medium to move between the two or more systems. The second output is the binary bytes which has been serialized into by the proto library.

Now let us write code to create Person struct from the auto generated file/package( person.pb.go) and serialize it into a buffer string using the proto package. Once done, make sure you push the repository on github to import the package in the main.go file. This will have multiple getter and setter methods for the structs to get and set the values. If you open this file you will see that it contains the auto generated code for us. This will create a Go target file in the present working directory from where the command is run (the dot) and make use of all the proto files to do so Protoc-gen-go is a plugin for the Google protocol buffer compiler to generate Go code. To compile our person.proto proto-buf file, cd to the protofiles directory and run: The second line package protofiles is the package name for go to compile. The AddressBook contains the list of Persons.Ī person has a name, id, email and list of PhoneNumbers. So we just created two main messages called Person and AddressBook.

Now open a fresh terminal and type protoc -version to confirm the installation.

Browse until C:\Program Files\protoc\bin and click ok.

Now search for Edit the system environment variable setting on start menu, double click on Path in the list.

I will extract it in the C:\Program Files\protoc folder (by creating the protoc folder).

I am on windows, so I will install download the latest stable package and set the environment variable from Edit the system environment variable setting in the control panel. We will install he protoc command line from

On the remote machine, de-serialize the data and consume it.

Serialize the data into binary format and send it to the other system.

Import the structs from the generated file and create data using those.

Compile the file for Go target language.

Install the protoc comman-line tool and the proto library.

We will make use of the structs (gotten from the compiled files) to create the binary data. To transfer data between the systems, we will make use of the compiled files from the proto proto files. Let us write a simple message in protobuf:Įnter fullscreen mode Exit fullscreen mode In Go, protocol buffers can be transported over different transports, such as HTTP/2Īnd Advanced Message Queuing Protocol (AMQP).Ī protocol buffer is a file, which when compiled, will generate a file accessible to the targetted programming language.

The output of the compilation will be classes and functions of the target programming language. Once a proto-buff file has beenn defined, we can compile it to a target programming language. Protocol Buffers allow us to define the data contract between multiple systems. Interesting right? It is, we will see how that works.

As per definition by Google: You can update your datastructure without breaking deployed programs that are compiled against the old datastructure format. Protobuf vs JSON Both are for serialization, however, the key difference is that Protobuf is binary data –interchange format whereas JSON stores data in human-readable text format. Protocol buffers is a data exchange format similar to JSON.

Compiling a protocol buffer with protoc.
