This page links to resources for learning about server programming in Go. The items are organized into sections by topic.

In Go servers, each incoming request is handled in its own goroutine. These goroutines share memory by communicating. LearnConcurrency outlines a course of study of Go's concurrency model, including techniques that are useful in server programming.

Communication

• Package net/http provides HTTP client and server implementations.
• Package encoding/json implements encoding and decoding of JSON objects as defined in RFC 4627.
• Package net/rpc provides access to the exported methods of an object across a network or other I/O connection.
• Package os/exec runs external commands.

Presentation

• Package text/template implements data-driven templates for generating textual output.
• Package http/template implements data-driven templates for generating HTML output safe against code injection.

Profiling and Performance

• Read Profiling Go Programs
• Read Arrays, slices (and strings): The mechanics of ‘append’
• Read the Frequently Asked Questions (FAQ), especially
  • Why does Go perform badly on benchmark X?
  • Why do garbage collection? Won't it be too expensive?
• Package bufio implements buffered I/O.
• Package runtime/pprof writes runtime profiling data in the format expected by the pprof visualization tool.
• Package net/http/pprof serves via its HTTP server runtime profiling data in the format expected by the pprof visualization tool.

Tracing, Monitoring, Logging, and Configuration

• Package expvar provides a standardized interface to public variables, such as operation counters in servers.
• Package flag implements command-line flag parsing.
• Package log implements a simple logging package.
• Package glog implements logging analogous to the Google-internal C++ INFO/ERROR/V setup.

Storage

• Package os provides a platform-independent interface to operating system functionality.
• Package path/filepath implements utility routines for manipulating filename paths in a way compatible with the target operating system-defined file paths.
• Package database/sql provides a generic interface around SQL (or SQL-like) databases.
