Microservices

When building microservices, choosing the right communication protocol is crucial. While REST and event-driven architectures have their place, gRPC offers a compelling alternative with strong typing, efficient binary serialization, and built-in support for streaming. In this guide, we’ll build a complete note-sharing application using gRPC microservices in Go, with a Vue.js frontend connected through a WebSocket gateway. Why gRPC for Microservices? gRPC brings several advantages to microservice architectures: Strong Typing: Protocol Buffers provide type-safe contracts between services Performance: Binary serialization is faster and more compact than JSON Code Generation: Auto-generate client and server code from .proto files Streaming: Built-in support for bidirectional streaming Language Agnostic: Works across many programming languages HTTP/2: Connection multiplexing, header compression, and server push However, browsers can’t make native gRPC calls. That’s where our WebSocket gateway comes in. ...

Building a real-time note-sharing application is a perfect use case for exploring event-driven architecture. In this comprehensive guide, we’ll build a production-ready system with two microservices (User and Note services) that communicate through NATS, delivering instant updates to a Vue.js frontend. Why Event-Driven Architecture? Traditional request-response patterns create tight coupling between services. When your Note service needs to notify users about changes, you don’t want to make synchronous HTTP calls to every service that cares about notes. Event-driven architecture solves this with loose coupling: ...
