![]() The project tries to solve the following challenges: This project tries to provide a modern approach to manage APIs, combining the Protobuf and OpenAPI specifications. I’m not planning on going very deep into the concepts and tools - we have a lot of posts about those out there - the intention here is to present an application example containing everything when developing contract-based APIs. In this blog post, I will walk through some concepts and technologies that we have placed in our bootstrap modern API management project. ![]() This project will definitely help you get an understanding of the API lifecycle and save you a lot of time when setting up your initial API architecture. We are addressing some of the main challenges that everyone faces when starting with this type of project. The idea of this project is to provide you with a bootstrap for your next API based project(e.g microservices). In this post, I am going to present a project containing patterns, tools, and technologies used to develop contract-based APIs which will help teams communicate and ensure compatibility. Each service must not break contracts until it's known that no other microservice relies on a particular contract version. To achieve this independence, each microservice must provide a versioned, well-defined contract to its clients. One of the most important aspects of microservices-based applications is the ability to deploy microservices completely independent of one another. This time, I will be talking about API contract management with Protobuf and OpenAPI. I am a tech-enthusiast, and I love sharing new technologies, ideas, and innovations about software development. It brings portability, excellent performance and a sophisticated protocol for use on the web or mobile front-end.Check out this open-source project to start learning how to manage modern APIs with protobuf and OpenAP ![]() GRPC-Web is an excellent option for web developers. The definition of types and services in Protocol Buffer works as documentation too - whoever consumes the service gets to know what to send in the request and what can be received in the response. With a low learning curve, new developers on a gRPC project can be productive quickly. Companies like Google, Netflix and Dropbox already use it in production. GRPC is a robust architecture that has several supporters. Now you are wondering “Should I adopt gRPC?” The full source code using Golang and VueJS (Quasar Framework) can be found in my GitHub repository. I started with a simple accounts.proto definition like this: Need client libraries for Rust, Python, Java, and 4 other languages? You no longer need to write HTTP clients for all of them. Easily generate client libraries: All of your service’s client libraries can be gRPC libraries.Tighter coordination between frontend and backend teams: With the entire RPC pipeline defined using Protocol Buffers, you no longer need to have your “microservices teams” alongside your “client team.” The client-backend interaction is just one more gRPC layer amongst others.Your client can interacty directlly with one or more gRPC servers, just calling the definied functions. ![]() End-to-end gRPC: Enables you to craft your entire RPC pipeline using Protocol Buffers.This development process removes the need to manage concerns such as creating custom JSON seralization and deserialization logic, wrangling HTTP status codes, managing content type negotiation etc. GRPC-Web, just like gRPC, lets you define the service “contract” between client (web) and backend gRPC services using Protocol Buffers. You can found more details in the official gRPC documentation and my previous post Building microservices in Go and Python using gRPC. GRPC is a super-fast, super-efficient Remote Procedure Call (RPC) system that will make your microservices talk to each other. With gRPC-Web, you can now easily build truly end-to-end gRPC application architectures by defining your client and server-side data types and service interfaces with Protocol Buffers. GRPC-Web is a JavaScript client library that enables web apps to communicate directly with gRPC backend services, without requiring an HTTP server to act as an intermediary. ![]()
