This library was useful if you always updating your server script but tired of waiting the server restart.

Install

To install this library, you can download from this repository or use

Sample Usage

var SkyLibrary = require('skylibrary');

var myserver = new SkyLibrary({
    path:__dirname+'/router' // Required
    // (Put all your router on root folder)
});

myserver.on('error', function(errcode, msg, trace){
    console.error("Error code: "+errcode+' ('+msg+')');
    if(trace){
        console.error(trace.message);
        for (var i = 0; i < trace.stack.length; i++) {
            console.error("   at "+trace.stack[i]);
        }
    }
    console.error("");
});

myserver.on('loading', function(filename){
    console.log('Loading '+filename);
});

myserver.on('loaded', function(urlpath, type){
    console.log('URL to '+urlpath+' was '+type);
});

myserver.on('stop', function(){
    console.log("Server shutdown");
});

myserver.on('started', function(){
    console.log("Server started on http://localhost:80");
});

myserver.on('removed', function(urlpath){
    console.log('URL to '+urlpath+' was removed');
});

myserver.on('httpstatus', function(code, callback){
    callback('HTTP status '+code);
});

myserver.on('navigation', function(data){
    if(data.headers['user-agent'].indexOf('Indy Library')!=-1)
        return; // Some people might have this browser bugs on port 80

    console.log("Navigation to '"+data.path+"'");
    console.log('  - '+data.headers['user-agent']);
});

myserver.start(80);

The main router of the server

// hello.js

// This will be initialized as an object on initialize
// you can keep your variable here and load it even
// the script reloaded
var scope = null;

// You can also live reload your other script
var dependency = require('./ext/hello.js');

function response(req, res, closeConnection){
    res.writeHead(200);
    var output = dependency.hello() + " " + (req.get.who ? req.get.who : 'world') + '!';
    //res.write(output);
    closeConnection(output);
}

module.exports = {
    // URL path
    path: '/hello', // URL path must be started with backslash
    // If you doesn't provide the backslash, it can't be accessed with URL
    // To use this router for all subpath '/hello#'

    // Response handler
    response:response,

    // Scope initialization after script loaded
    scope:function(ref, allRef){
        scope = ref;

        // You can also access other scope with 'allRef'
    }
}

When you want to reload your script dependency, you should put it inside your server folder and specify it's parent in module.exports

// ext/hello.js
function hello(){
    return 'Hello';
}

module.exports = {
    // This parent is hello.js
    childOf:'hello',
    hello:hello
}
