Learn GO with Real Code Examples
Updated Nov 21, 2025
Architecture
Compiled binaries with static linking
Goroutine scheduler within runtime
Garbage-collected memory management
Package/module system for code organization
Cross-platform and architecture support via build tags
Rendering Model
N/A - Go is system/backend language, not GUI-focused
Can output text, JSON, HTML, or network streams
Integrates with frontend via APIs
CLI and network I/O as primary interface
Optional GUI via third-party libraries
Architectural Patterns
Procedural and modular package structure
Concurrency via goroutines and channels
Interface-based polymorphism
Event-driven network servers
Pipeline-style data processing
Real World Architectures
RESTful APIs
Microservices with gRPC
Concurrent data processing pipelines
Cloud-native infrastructure tools
Distributed systems and message brokers
Design Principles
Simplicity and readability first
Built-in concurrency primitives
Fast compilation and execution
Garbage collection for memory safety
Strong standard library for networking and system tasks
Scalability Guide
Use goroutines and channels for concurrent workloads
Optimize memory and I/O usage
Split applications into microservices
Use interfaces and modular design
Benchmark and profile with pprof
Migration Guide
Port scripts from Python/Perl to Go for performance
Use goroutines to parallelize tasks
Replace dynamic typing with explicit types
Modularize code into packages
Test cross-platform builds
