LearnServerProgramming

This page links to resources for learning about server programming in Go - both web services and mobile backends. The items are organized into sections by topic.

Getting Started

• Read Writing Web Applications with the Go standard library
• Read Building Web Applications in Go from the author of the Negroni and Martini webserver toolkits.
• Read Build a Web Application With Go from the author of the BeeGo web framework
• Read Building Your Own Web Framework in Go a 5-part series.
• Code A Tour of Go: Web Servers and HTTP Handlers
• Watch Go: code that grows with grace
• Download a full working 3-tier application example from the Sourcegraph Team.

Middleware

A topic you will see discussed frequently is "middleware". If you're not familiar with that term, we suggest you start out by reading a few of these articles:

• Writing Handsome Golang Middleware 2015-05-05
• Middleware in Go: Best practices and examples 2014-11-13
• Custom Handlers Part 1 - Avoiding Globals, Part 2 - Error Handling 2014-07-16
• Making and Using HTTP Middleware 2014-10-21
• Writing HTTP Middleware in Go 2013-10-09

Toolkits and Frameworks

Before you decide to adopt a third party web framework or toolkit, keep in mind that the Go standard library provides all of the tools you need to build a sophisticated, modern web application. Keeping with Go's preference for simplicity and composability over complexity and magic, we suggest you see how far the standard library can take you.

If you decide you need a bit more infrastructure, start by looking at some of the toolkits and libraries available.

Toolikits & Libraries & Microframeworks

• Gorilla Toolkit
• Negroni Toolkit - Idiomatic HTTP Middleware for Go
• Echo Framework - Fast and Unfancy
• Goji Web Microframework

• YAM - Yet Another Mux

Frameworks

• Utron - Lightweight MVC framework for web applications.

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 html/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?

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.
