Backend Communication Current: WebRTC gRPC Streaming All Posts NATS & JetStream What is WebRTC? WebRTC (Web Real-Time Communication) enables peer-to-peer audio, video, and data sharing directly between browsers and native applications. Unlike traditional client-server models, WebRTC allows clients to communicate directly with each other after establishing a connection through a signaling server. ...
Backend Communication Current: WebSockets Server-Sent Events All Posts gRPC Streaming What are WebSockets? WebSockets provide full-duplex, bidirectional communication channels over a single TCP connection. Unlike HTTP’s request-response model, WebSockets enable both client and server to send messages independently at any time, making them ideal for real-time applications. ...
If you’re new to real-time web applications and want to understand the fundamentals before diving into event-driven microservices, this tutorial is for you. We’ll build a simple but fully functional note-sharing app using WebSockets, Go, and Vue.js-perfect for learning the basics. Why Start Simple? Before jumping into NATS, Kafka, or complex event-driven architectures, it’s crucial to understand: How WebSocket connections work Real-time bi-directional communication Broadcasting messages to multiple clients State management in real-time apps This tutorial gives you that foundation with minimal dependencies and straightforward code. ...
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: ...
Backend Communication Current: Server-Sent Events HTTP Polling Patterns All Posts WebSockets What are Server-Sent Events (SSE)? Server-Sent Events (SSE) is a server push technology that enables servers to push real-time updates to clients over a single HTTP connection. Unlike WebSockets, SSE is uni-directional (server → client only) and uses the standard HTTP protocol, making it simpler and more reliable through proxies and firewalls. ...
Backend Communication Current: HTTP Polling Patterns Previous All Posts Server-Sent Events What are HTTP Polling Patterns? HTTP polling patterns are techniques for achieving near-real-time communication between clients and servers using the standard HTTP request-response model. While not truly real-time like WebSockets, these patterns are simpler to implement, easier to debug, and work reliably across all networks and proxies. ...
