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

Go servers process each request in its own goroutine.  To share memory safely, these goroutines must communicate.  [LearnConcurrency](/golang/go/wiki/LearnConcurrency) outlines a course of study.
## Communication

- [Package net/http](http://golang.org/pkg/net/http) provides HTTP client and server implementations.
- [Package encoding/json](http://golang.org/pkg/encoding/json) implements encoding and decoding of JSON objects as defined in RFC 4627.
- [Package net/rpc](http://golang.org/pkg/net/rpc) provides access to the exported methods of an object across a network or other I/O connection.
- [Package os/exec](http://golang.org/pkg/os/exec) runs external commands.
- Read [Go Concurrency Patterns: Context](http://blog.golang.org/context)

## Presentation

- [Package text/template](http://golang.org/pkg/text/template) implements data-driven templates for generating textual output.
- [Package http/template](http://golang.org/pkg/html/template) implements data-driven templates for generating HTML output safe against code injection.

## Profiling and Performance

- Read [Arrays, slices (and strings): The mechanics of 'append'](http://blog.golang.org/slices)
- Read [Profiling Go Programs](http://blog.golang.org/profiling-go-programs)
- [Package runtime/pprof](http://golang.org/pkg/runtime/pprof) writes runtime profiling data in the format expected by the pprof visualization tool.
- [Package net/http/pprof](http://golang.org/pkg/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](http://golang.org/pkg/expvar) provides a standardized interface to public variables, such as operation counters in servers.
- [Package flag](http://golang.org/pkg/flag) implements command-line flag parsing.
- [Package log](http://golang.org/pkg/log) implements a simple logging package.
- [Package glog](https://github.com/golang/glog) implements logging analogous to the Google-internal C++ INFO/ERROR/V setup.

## Storage

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