[![Coverage Status](https://coveralls.io/repos/brettlangdon/yaps/badge.png?branch=master)](https://coveralls.io/r/brettlangdon/yaps?branch=master)
[![NPM version](https://badge.fury.io/js/yaps.png)](http://badge.fury.io/js/yaps)

YAPS is plugin based HTTP server that gets out of your way and lets you do what you need to do.

## Installation
### Via NPM
```bash
npm install [-g] yaps
```

### Via Git
```bash
git clone git://github.com/brettlangdon/yaps.git
cd ./yaps
npm install
```

## Usage
```javascript
var yaps = require("yaps");
var user_auth = require("user_auth");
var user_routes = require("user_routes");
var admin_routes = require("admin_routes");

// create instance of yaps application
var server = new yaps({
    bind: "0.0.0.0:8000",
});

// register each plugin
server.registerPlugin(user_auth);
server.registerPlugin(user_routes);
server.registerPlugin(admin_routes);

// start the server listening at http://0.0.0.0:8000
server.start();
```

## Writing Plugins
Plugins are meant to be a small contained representation of a portion of your application.
This way you can easily package and move portions of your application around.

### Example
```javascript
var yaps = require("yaps");

var plugin = function(){
    this.addRoute("GET", "/test", this.handle_test);
    // OR
    this.GET("/test", this.handle_test);

    // this handler gets called for every new request regardless of route
    this.on("setup", this.request_setup);

    // for when there isn't a handler that responds to the request, call this
    this.on("not-found", this.not_found);
};

// `request` is the current request
// `server` is the current yaps instance
// `respond` is a function which must be called by each handler
plugin.prototype.handle_test = function(request, server, respond){
    if(server.some.setting >= 200){
	    // this passes execution to the next handler for this route
        respond(null);
    } else{
	    // this interrupts the handler chain and returns to the user
        respond(200, "Thanks for visiting /test", {
            extra_header: "used /test",
        });
    }
};

plugin.prototype.request_setup = function(request, server, done){
    // do some setup stuff here, like setup sessions or do auth
	done();
};

var server = new yaps({
    bind: "0.0.0.0:8000",
});
server.registerPlugin(plugin);
server.start();
```
