nodejs-mvc

Fast and simple MCV in nodejs

[Section 1] Starting an Application

	var app	= require("nodejs-mvc");
	var appVars	= app.getVars();

	var server	= require("http").createServer(function( request, response, next ) {
		app.handleServerResponse( request, response, next );
	});

	app.sessionCookieName("ssid");
	app.sessionDynCookieName("ssid");
	app.sessionDynCookieDomain(false);

	// from request.secretCookieKey it reads secret key for decoding cookie



	app.sessionDynAutoUpdate(true);
	app.sessionDynExpire(60*60*2);

	app.setRootPath( __dirname );
	app.setPublicPath( __dirname+'/public');
	app.setModulePath( __dirname+'/app/modules');
	app.runBootstrap();

	server.listen(8080);

Starting an Application with an additional static server

	var app	= require("nodejs-mvc");
	var appVars	= app.getVars();

	app.sessionCookieName("ssid");
	app.sessionDynCookieName("ssid");
	app.sessionDynCookieDomain(false);
	app.sessionDynAutoUpdate(true);
	app.sessionDynExpire(60*60*2);

	app.setRootPath( __dirname );
	app.setPublicPath( __dirname+'/public');
	app.setModulePath( __dirname+'/app/modules');

	var server	= require("http").createServer(function( request, response, next ) {
		app.handleServerMidleware(request, response, function () {
			if (request.url.match(/(\/|)(styles|images|scripts)/)) {
				// will be search files in public path
				app.handleStaticResponse(request, response);
			} else if (request.url.match(/(\/|)(node-docs)/)) {
				// will be search static files in a custom path
				app.handleStaticResponse(request, response, "/var/www/node-js/");
			} else {
				app.handleServerResponseLogic( request, response, next );
			}
		});
	});

	app.runBootstrap();

	server.listen(8080);

	// method to call handleStaticResponse
	// in callback you get only one parameter ( err ) in case of file was not found
	//	app.handleStaticResponse(request, response, path, callback);
	//	app.handleStaticResponse(request, response, path);
	//	app.handleStaticResponse(request, response, callback);

Application adding controllers and actions

A demo application you will see in ./demo/mvc-sample/app.js

Defining the folder were a stored controllers: `app.setModulePath("app/modules");

File structure of an controller and actions:

    app
    ⊢  modules
        ⊢ index            # folder for controller "index"
           ⊢ controller
              ⊢ index.js   # default action
              ⊢ create.js  # default other action named "create"

Actions's file "app/modules/index.js"

	module.exports	= {
		"public"	: true,	// define action as public default:false
		"postData"	: false,	// if `true` the service will wait while POST data
								// will be loaded in request object
								// POST data will be returned by request.postVars()
								// FILES will be returned by request.fileVars()
		"maxPostSize"	: 1024*1024, // default 1Mb
								// may be set true if action is sync without callbacks
		capture	: function( request, response, app, controller, action ) {
			// redner the view index
			controller.render( response, 'index', { username: "sergiu gordienco" });
		}
	};

Controllers's Methods

	module.exports	= {
		"public"	: false,	// define action as public default:false
		capture	: function (request, response, app, controller, action) {
			// list controller methods
			app.debug(true);
			app.console.log(controller);
			response.end();
		}
	};

• controller.getViewer() - returns viewer Object
• controller.getName() - returns controller name
• controller.getView( str_viewName ) - returns view Object or false if it don't exists
• controller.viewExists( str_viewName ) - returns Boolean trueif view exists else returnsfalse`
• controller.render( response, viewName, parameters ) - if viewExists render view else doesn't do any thing
• controller.removeView( viewName ) - removes view if it exists under an action on success return true else returns false
• controller.getAction( actionName ) - return a action Object or false
• controller.actionExists( actionName ) - return true if action exists
• controller.addAction( actionName, configActionObject ) - add action to controller if action already exists returns false
• controller.removeAction( actionName ) - removes action from controller on success returns true else false
• controller.getVars() - return controllers vars object that can be used by all functions, and it is common for all user sessions

Action's Methods

	action = controller.getAction("library");

• action.getController() - returns controller object
• action.getName() - return action name
• action.isPublic() - returns true if public is true else false
• action.usePostData() - returns true if postData is true else false
• action.maxPostSize(numberBytes) - if numberBytes is a number it updates maxPostSize parameter, even function returns current maxPostSize
• action.run( request, response ) - run a action and returns true on success else returns Error object

Session vs SessionDyn

Using a session in a action:

module.exports	= {
	public	: 1,
	capture	: function (request, response, app, controller, action) {
		var sess = request.session
		if (sess.views) {
			sess.views++
			response.setHeader('Content-Type', 'text/html')
			response.write('<p>views: ' + sess.views + '</p><p>expires in: ' + (sess.cookie.maxAge / 1000) + 's</p>', function (err) {
				if (err) console.error(err);
				response.end();
			});
		} else {
		sess.views = 1
			response.end('welcome to the session demo. refresh!')
		}
	}
}

SessionDyn request.sessionDyn

sessionDyn is much faster then other sessions, but it is stores object references in memory, it is very optimized, and practically, doesn't store additional metadata.

• request.sessionDyn.ip() - returns current user ip
• request.sessionDyn.host() - returns request.headers.host
• request.sessionDyn.origin() - returns request.headers.origin;
• request.sessionDyn.hashSession( sessionId ) - returns hashed sessionId
• request.sessionDyn.genSessionId() - returns a new valid sessionId
• request.sessionDyn.sessionId() - returns current sessionId
• request.sessionDyn.setExpire( secconds, sessionId ) - set session expire timeout, if sessionId is undefined it will update current session
• request.sessionDyn.getExpire( sessionId ) - get session expire timestamp, if sessionId is undefined it will work with current session
• request.sessionDyn.getCreated( sessionId ) - get creation timestamp for sessionDyn with id equal to sessionId
• request.sessionDyn.sessionExists( sessionId ) : function( sessionId ) - retruns true if exists a sessionDyn with iq equal with sessionId
• request.sessionDyn.getVars( sessionId ) - will return variables from a sessionDyn if it exists, if sessionId is undefined will return variables from current sessionDyn if sessionExists else retruns false

Request methods

• request.headers - object that contains headers { "header name" : "header value", .... }
• request.urlObject - object that resulted on parsing current url

    var url = "https://www.example.com/path/to-an-url?get=references#hash-link";
    console.log(url.parseURL(true));

Result:

    {
        "original"  : "https://www.example.com/path/to-an-url?get=references#hash-link",
        "origin"    : "https://www.example.com","domain":"www.example.com",
        "domain_short"  : "example.com",
        "pathname"  : "/path/to-an-url",
        "reqQuery"  : "get=references",
        "protocol"  : "https",
        "protocoll" : "https://",
        "url"       : "www.example.com/path/to-an-url?get=references#hash-link",
        "url_p"     : "https://www.example.com/path/to-an-url?get=references#hash-link",
        "isIp"      : "www.example.com",
        "get_vars"  : {
            "get"   : "references"
        }
    }

• request.controller - current controller name
• request.controllerAction - current action name
• request.params - current parameters array
• request.postData - Buffer Object where was stored original POST data
• request.postVars() - returns POST vars stored in a object ( available as request.body )

	// for PUT method or other
	app.put(function (request, response, next) {
		request.postDataColect(next);
	});

	app.put('/chat',function (request, response) {
		response.send(request.body);
	});

• request.fileVars() - returns FILE vars stored in a object
• request.sessionDyn - returns sessionDyn Object
• request.session - returns session Object
• request.redirect( url, status ) - redirects to a specified url with a specified status ( default status = 302 )
• request.postDataState - if POST data length is less that action.maxPostSize then it is true else false

Response Methods

• response.req - request related tu current request

Templates Env references

var app = require("nodejs-mvc")();

app.templateEnv({
	author: "sergiu-gordienco"
});

// in templates will be available a reference env with data { author: "sergiu-gordienco" }

application viewer - Viewer Object

Small overview

	debugMode	: function (status) {
		// updates or just return current debug status
	},
	getEnvVars	: function() {
		// return envVars;
	},
	updateEnvVars	: function( data ) {
		// updates env vars
	},
	renderCode	: function (code, vars, virtualFilePath, cb) {
		// code - the code to e rendered
		// vars - this reference will be available in template as "vars"
		// virtualFilePath - reference path that will be used for searching included files
		// cb - callback for getting results
			// arguments:
				// error - ( Array of errors ) or ( undefined )
				// html - String code
	}

Email Object

Examples

	var app = require("nodejs-mvc");
	var Email = app.Email
	var myMsg = new Email(
	{ from: "[email protected]"
		, to:   "[email protected]"
		, subject: "Knock knock..."
		, body: "Who's there?"
	});

	// if callback is provided, errors will be passed into it
	// else errors will be thrown
	myMsg.send(function(err){ ... })

Note that no callback was passed into send(), therefore errors will throw.

Options

	new Email(config)

config options:

• to {array|string}
  • Email address(es) to which this msg will be sent
• from {string}

Templates FaceboxTPL

To view parameters that are send have following structure

On template Rendering we have following variables

	// variables that a sent from controllers
	var vars	= {};

	var env		= {
		error	: [],
		vars	: envVars,
		path	: "", // file path of current rendered template
		dirname	: "", // dirname of current rendered template
		render	: function( text, vars, env ) {}, // render function
		renderFile	: function( file, vars, callback ) {}, // render file function
			// callback( error {{ [] or false }}, htm)
	};

	// env vars sent from app
	env.vars = {
		response : [object] // http response object
	}

An example how to render a view:

	// file app/modules/index/controller/pageviews.js

	// file represents action page-views from controller index
	var _vars	= {
		pageviews	: 0
	};
	module.exports	= {
		public	: true,
		capture	: function( request, response, app, controller, action ) {
			// increasing page-views
			// sending page-views to view
			controller.render( response, 'index', { pageviews: (++_vars.pageviews) });
		}
	};

Using Extended prototype

Extended template operations regarding prototype

Escaping HTML chars

For strings references

	<a href="{{ vars.url.toHtml() }}">{{ vars.user.name.toHtml() }}</a>

For other type of references

	<a href="{{ ((vars.url || "") + "").toHtml() }}">{{ ((vars.user.name || "") + "").toHtml() }}</a>

Global Functions

Extend/Merge Objects

	objMerge	= function(obj1, obj2, obj3, ..) { /*...*/ }

extend object objEncodeURL({ name: "foo", val : "23"}, { val: 24, val2: "abc"} ) result { name: "foo", val: 24, val2: "abc" }

remove poperty from object objEncodeURL({ name: "foo", val : "23"}, { val: null, val2: "abc"} ) result { name: "foo", val2: "abc" }

Encode URL variables

	objEncodeURL	= function(data, prefix) { /*...*/ }

objEncodeURL({ foo: 5, bar: [1,5,9], cid: "id-3453" }) result foo=5&bar[0]=1&bar[1]=5&bar[2]=9&cid=id-3453

objEncodeURL([{ foo: 5, bar: [1,5,9], cid: "id-3453" }, "test", { value: "123" }], "data") result data[foo]=5&bar[0]=1&bar[1]=5&bar[2]=9&cid=id-3453

Check references' types

Check if reference is an Array. Returns boolean

	isArray = function() { /*...*/ };

Check if reference is a String. Returns boolean

	isString	= function(val) {};

Global Object m_store

Method m_store.empty:

Returns true if v is empty ( undefined, null, 0, "0", false, [], "" ) else returns false; if objectCheck = true then m_store.empty also will turn true for empty objects.

	m_store.empty	: function(v, objectCheck) { /*...*/ };

Method m_store.is_numeric:

	m_store.is_numeric	: function(v) { /*...*/ },

Return true if reference v is a number or a numeric string

Method m_store.type:

	m_store.type	: function(val) { /*...*/ }

Detects following type of reference types,

• return 'null' for null reference
• return 'string' for String reference or instanceof String
• return 'boolean' for boolean reference
• return 'undefined' for undefined references
• return 'function' for functions
• return 'number' for number
• return 'array' for array objects
• return 'regexp' for Regular Expressions
• return 'object' for Objects

Method m_store.json:

Following function encodes a reference into JSON object. The function will encode different references, even: functions, Infinity, -Infinity, NaN, undefined

maxEncodeDepth if is not defined, default is 5

	m_store.json	: function(val, maxEncodeDepth ) {}

Method m_store.getv:

Return parsed JSON value. When safeMode is not specified or is false, the method m_store.getv uses eval (not safe)

With safeMode = true will be used function JSON.parse ( JSON parse will not be able to decode functions, Infinity, -Infinity or NaN references )

	m_store.getv	: function(val, safeMode) { /*...*/ }

String Prototype

Subs Method:

	String.prototype.subs	= function(string, offset, length) {}

"abcdefghi".subs(2) is equal to "ab" "abcdefghi".subs(2,3) is equal to "cde" "abcdefghi".subs(-2) is equal to "hi" "abcdefghi".subs(1,-2) is equal to "bcdefg" "abcdefghi".subs(-4,3) is equal to "fgh"

Subs Method:

	String.prototype.toHex = function(utf8String) { /*...*/ return hex_str; }
	String.prototype.fromHex = function(){ /*...*/ retrun utf8_str; },

"TEST".toHex() is equal to "54455354" "54455354".fromHex() is equal to "TEST" "54455354".fromHex() is equal to "TEST"

UTF-8 vs Unicode Function .toHex() and .fromHex is working with UTF-8 Strings but javascript is working with Unicode "€".toHex() (Unicode) 1 char in HEX is 2 chars "20ac" "20ac".fromHex() is " ¬"

So correctly to encode UnicodeText to Hex is "€".utf8encode().toHex() and the result is "e282ac" and "e282ac".fromHex().utf8decode() is "€"

Escape HTML

	String.prototype.toHtmlSimple	= function() { /*...*/ retrun str; },
	String.prototype.toHtml = function(){ /*...*/ return str;},
	String.prototype.cleanTags	= function() { /*...*/ return str; }

Check if word exists in a list of words separated by " "

	// add class
	String.prototype.add_Class = function(x){},
	// remove class
	String.prototype.del_Class = function(x){},
	// check is calss exists
	String.prototype.fnd_Class = function(x){},

String letterCase change

	String.prototype.swp_case = function(){ return str; }
	String.prototype.ucfirst = function(k){ return str; }

Array method (inArray) - search an element in a array with a defined comparator

	/*
		comparator posible values:
		1. '==='	- check if is strict equal
		2. '=='		- check if is equal
		3. a _function_ :
		function(searched_item,array_item) {
			return searched_item === array_item
		}
	*/
	Array.prototype.inArray	= function(a,comparator) { /*...*/ },

	Array.prototype.split	= function (elem, num, cmp) { /*...*/ },

Split an Array by an a section value of one or more bytes

	Array.prototype.splitSect	= function(elem, num) {
		return this.split(elem, (num || 0), "indexOfSect");
	},

Convert a Array to an parameter object

	Array.prototype.toParamObj	= function() { /*...*/ },

Remove from Array undefined values

	Array.prototype.resetArray	= function() {return this.filter(function(v) { return ( typeof(v) != "undefined" ); })},

		/* ... */
		return lines;
	}

Split a Buffer by an a section value of one or more bytes

	Buffer.prototype.splitSect	= function(elem, num) {

Console object was Extended

was added method prompt:

Example:

console.prompt("rerun tests? [y/n]: ", function (err, buffer) {
	var response = buffer.toString().replace(/^\s*(.*?)\s*$/, '$1');
	if (response === 'y') {
		// TODO what you want...
	}
});

console output now is much better formated ( for teminal vt100 )
