Go Fiber REST API & Database Services
A production-oriented reference implementation of high-throughput RESTful services using Go Fiber and GORM with connection pooling, migrations, and clean repository patterns.
Key Architectural Highlights
- Fasthttp-powered zero-allocation routing
- Tuned database connection pooling (GORM)
- Repository pattern for decoupled data access
- Automated schema migrations
Overview
A robust reference service demonstrating modern Go backend development patterns. Built around the high-speed Fiber framework (backed by Fasthttp) and integrated with GORM for relational database interaction.
Accompanied by published technical guides on Dev Genius:
- Building High-Performance REST APIs using Go Fiber
- Working with Database: REST APIs in Go Fiber using GORM
Key Patterns Demonstrated
- Layered Architecture: Strict separation between Transport layer (Fiber HTTP handlers), Service layer (business logic), and Data layer (GORM repository).
- Connection Pool Optimization: Configured
SetMaxOpenConnsandSetMaxIdleConnsto prevent socket starvation under sustained concurrent loads. - Context Propagation: Passed client cancellation signals into database transactions to terminate abandoned backend queries.
- Containerization: Multi-stage Dockerfiles producing minimal (<15MB) deployment containers.
