![]() ![]() There are protoc versions for OS X, Windows, and Linux. The protoc tool is operating system specific. However, in terms of real-world adoption, developers tend to focus on the plugins that are relevant to their company's preferred programming languages. Thus, it takes a bit of time to master the details of each. proto file.Įach plugin works a little differently. One the other hand, the GoLang plugin, for example, will also auto-generate code that describes the message's data along with its serialization and deserialization logic as well as the business logic for the services defined in the API's. Also, the auto-generated code attaches logic to each object that will serialize and deserialize the message's data to and from the Protocol Buffers binary format. These auto-generated objects will contain the data fields that correspond to a particular message. For example, there is a JavaScript plugin that generates JavaScript code that represents objects that correspond to the messages in a. Thus, a plugin developer writes an add-in for protoc that will auto-generate code for the given language in a particular way. proto PluginsĪs mentioned above, protoc is the binary executable used to auto-generate boilerplate code. The procedure retrieves a car by vehicle identification number (VIN). proto file defines a single data structure, car along with a service, CoolCarService that publishes a procedure GetCar(). Also, we'll share links to a number of lessons in the Katacoda interactive learning environment that we at ProgrammableWeb have created for your benefit. proto file that's part of an example demonstration project named SimpleService. We'll cover auto-generating code in JavaScript, C#, and GoLang. The objective of this article is to explain how to get protoc up and running to auto-generate gRPC code in a variety of programming languages. protoc is a binary executable that allows programmers to auto-generate backing code for an API as defined in the API's. ![]() As you can see, it's a lot of work.įortunately, the gRPC community has created a tool that does a lot of the mundane work that goes with creating code for a gRPC API. And, if that's not enough, you'll need to write the code that routes, calls to and from specific services defined for the gRPC API. Figure 1: gRPC uses the Protocol Buffers binary format as the lingua franca of data exchangeĪlso, building your own gRPC API code from scratch means writing the business logic for the services defined in the API's. ![]()
