Once the developer has created the Protocol Buffer file(s) with all messages, we can use a ‘protocol buffer compiler’ (a binary) to compile the written protocol buffer file, which will generate all the utility classes and methods which are needed to work with the message. For example, as shown in the above Person message, depending on the chosen language, the generated code will look like this.

Supported middlewares by gRPC framework.

• grpc-gateway

  gRPC to JSON proxy generator following the gRPC HTTP spec

  

protoc-gen-grpc-gateway — plugin for creating a gRPC REST API gateway. It allows gRPC endpoints as REST API endpoints and performs the translation from JSON to proto. Basically, you define a gRPC service with some custom annotations and it makes those gRPC methods accessible via REST using JSON requests.

• go-proto-validators

  Generate message validators from .proto annotations.

protoc-gen-go-validators — a plugin that allows to define validation rules for proto message fields. It generates a Validate() error method for proto messages you can call in Go to validate if the message matches your predefined expectations.

• protolint

  A pluggable linter and fixer to enforce Protocol Buffer style and conventions.

protolint - a plugin to add lint rules to proto files.

  Evans: more expressive universal gRPC client

Note: gRPC services can also be tested from CLI using tools like evans-cli. But for that reflection needs (if not enabled the path to the proto file is required) to be enabled in gRPC servers. This compare link shows the way to enable reflection and how to enter into evans-cli repl mode. Post entering repl mode of evans-cli, gRPC services can be tested from CLI itself and the process is described in evans-cli GitHub page.

  Newman is a command-line collection runner for Postman

  

protoc-gen-swagger — a companion plugin for grpc-gateway. It is able to generate swagger.json based on the custom annotations required for gRPC gateway. You can then import that file into your REST client of choice (such as Postman) and perform REST API calls to the methods you exposed.

  Protocol Buffers - Google's data interchange format

  

gRPC uses protocol buffers (it is an open source message format) as the default method of communication between client and server. Also, gRPC uses HTTP/ 2 as the default protocol.
