hapi-cookie

#Hapi-cookie ##Welcome to my first hapi module

hapi-cookie simply sets a cookie in the response before it goes out.

I developed this module because I was having problems setting cookies. Hapi provides the server.state / plugin.state to set a "state" cookie which works perfectly. The problem was that I couldn't set things like expiration, path, domain etc.. just a name and value. So, I started looking for a way to do this on my own.

##How does hapi-cookie work?

The server.ext seemed like a logical place to start. There, I trigger off the "onPreResponse" event and extend "request.response.headers" with (possibly multiple) "Set-Cookie" instances. It's relatively simple and a little embarrassing how long it took me to come up with it.

##How to use this module

In your manifest.json:

{
    "servers" : [
        {
            "port": {{whatever port number}},
            "options" : {
                {{whatever options you want to set}}
            }
        }
    ],
    
    "plugins" : {
    
        "hapi-cookie" : {}
    }
}

Of course your manifest might be much larger with many more plugins and servers.

Then use the single exposed API to set a cookie:

var hapiCookie = plugin.plugins['hapi-cookie'];

/*
hapiCookie.setCookie( 
    String nameOfCookie, 
    String valueOfCookie, 
    String GMTformat, 
    String path, 
    String domain, 
    Boolean isSecure, 
    Boolean is HTTPOnly, 
    callback(error, cookie value){}
)
*/

// for example

var dur = 100000000; // add some tiem so the cookie doesn't expire right away
var dte = new Date(new Date().getTime()+dur).toUTCString();

hapiCookie.setCookie("newCookie", "cookieValue", dte, "myDomain.com", "/", true, true, function(e, cookieVal){

    if(e){ 
        console.log("The cookie was not set");
    } else {
        console.log("Cookie Set : "+cookieVal);
    }
}

Future changes:

• There is also the possibility of using request.headers.state to attach a "Set-Cookie". Might want to fully investigate using that instead. Or give users the option.

• Add more API's to add other headers?
