Go in Practice, Second Edition

Go uses lightweight goroutines and typed channels for concurrent processing and communication, making concurrency easier and more efficient than traditional thread-based models. [1]

Goroutines run functions concurrently, while channels act as typed pipelines for sending and receiving data between them, enabling safe and structured communication. [1] [2]

Generics allow developers to write more reusable and concise code by enabling functions and types to operate on different data types without sacrificing type safety. [1]

Go provides powerful standard library support for routing, middleware, handling headers, cookies, and form data, making it easy to build production-quality HTTP servers. [1]

Go's templating system supports template inheritance, nesting, and secure rendering of objects to HTML, as well as robust patterns for email templates. [1]

Go enables full-featured REST API clients, custom error handling, JSON parsing, and multiple strategies for API versioning, including URL and content type approaches. [1] [2]

gRPC is a high-performance RPC framework, and Go provides first-class support for defining and consuming gRPC services for efficient service-to-service communication. [1]

Best practices include containerizing applications, avoiding vendor lock-in, monitoring the Go runtime, and cross-compiling for different operating systems and architectures. [1] [2]

Go offers patterns for designing microservices, keeping them highly available, and optimizing communication between services, including speeding up intracloud communication. [1]

Go's reflection system allows runtime inspection of types and values, while code generation tools enable automated creation of Go code and custom struct annotations. [1] [2]
