Focuses on code debugging, performance optimization, and real-world engineering, sharing efficient development tips and pitfall guides. We break down technical challenges in a down-to-earth style, helping you craft handy tools so every line of code becomes a problem‑solving weapon. 🔧💻
This article walks through refactoring a tightly‑coupled Go API gateway into a lightweight, plugin‑driven microkernel architecture, detailing the motivation, design of core abstractions, code examples, and the resulting gains in extensibility, maintainability, and flexibility.
This guide explains why traditional logs fail in distributed systems and walks through integrating OpenTelemetry and Jaeger into a Go microservice project, covering tracing module setup, configuration, context propagation for HTTP, gRPC, RabbitMQ, GORM, Docker deployment, and future observability enhancements.
This article examines the challenges of tangled initialization in Go's main.go, demonstrates a manual DI container for an order service, and contrasts it with Google’s compile‑time wire tool for a user service, offering practical code examples, step‑by‑step guidance, and recommendations for projects of different sizes.
This article walks through a real‑world Go project, showing why adding unit tests to core modules prevents regressions, how to mock tightly‑coupled dependencies, and provides complete example test code and best‑practice tips for reliable backend development.
An in‑depth post‑mortem of a real Go microservice outage reveals how committing a DB transaction before publishing a RabbitMQ event caused duplicate charges, and demonstrates how adopting the Transactional Outbox pattern restores atomicity, prevents ghost bugs, and improves reliability.
This article walks through a complete performance upgrade of a Go microservice by defining protobuf contracts, generating gRPC code, running both HTTP and gRPC servers side‑by‑side, and using gRPC‑Gateway to keep REST compatibility, resulting in lower latency and a future‑ready architecture.
This article examines common pitfalls of asynchronous Go logging—such as channel blocking, GC pressure, and poor API design—and presents concrete solutions using non‑blocking writes, sync.Pool object reuse, and context‑aware variadic APIs, all demonstrated with real code from the easyms.golang project.
This article dissects a production‑grade Go database access framework for microservices, covering unified interface abstraction, factory pattern for multi‑DB support, PostgreSQL array handling, read‑write splitting with load balancing, Redis cache protection, monitoring, and deployment considerations, with full code examples and open‑source links.
This article walks through a production‑grade OAuth2 authentication center built with Go and Gin, covering a three‑layer architecture, stateless JWT handling, key‑rotation, short‑hash token revocation, high‑availability design, and practical open‑source references.
The article explains how abandoning go-kit and rebuilding the EasyMS project around configuration governance reshaped the project structure, startup flow, and service evolution, delivering an engineering‑grade configuration system with versioning, atomic snapshots, deep merging, and safe hot‑updates for long‑term microservice maintenance.
