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

Getting Started

• Code A Tour of Go: Web Servers and HTTP Handlers
• Read Writing Web Applications
• Read LearnConcurrency
• Watch Go: code that grows with grace

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.
