Twister is fast, modular and lightweight framework for building applications in the Go programming language.

• Routing: Request to handler mapping with using regular expressions.
• Utilities: Static file server, file uploads, cookies, form data, headers and other HTTP meta-data.
• Server: Production quality HTTP server and adapter for Google App Engine.

Here is the canonical "Hello, world" example application for Twister:

package main

import (
    "github.com/garyburd/twister/server"
    "github.com/garyburd/twister/web"
    "io"
)

func serveHello(req *web.Request) {
    w := req.Respond(web.StatusOK, web.HeaderContentType, "text/plain; charset=\"utf-8\"")
    io.WriteString(w, "Hello World!")
}

func main() {
    h := web.NewRouter().Register("/", "GET", serveHello)
    server.Run(":8080", h)
}

Twister requires a working Go development environment. The Getting Started document describes how to install the development environment. Once you have Go up and running, you can install Twister with a single command:

goinstall github.com/garyburd/twister/server

The Go distribution is Twister's only dependency.

• web - Defines the application interface to a server and includes functionality used by most web applications.
• server - An HTTP server impelemented in Go.
• oauth - OAuth client.
• websocket - WebSocket server implementation.
• expvar - Exports variables as JSON over HTTP for monitoring.
• pprof - Exports profiling data for the pprof tool.
• gae - Support for running Twister on Google App Engine.

• wiki - The Go web application example converted to use Twister instead of the Go http package.
• demo - Illustrates basic features of Twister.
• twitter - Login to Twitter with OAuth and display home timeline.
