Mazagran

Opinionated node.js framework

Installation

npm install mazagran --save

Getting started

create a server.js file

//require mazagran
var mazagran = require('mazagran');

var configuration = mazagran.configuration;
configuration.addConfig('config.json'); //add a config file

//create DI container
var DIFactory = mazagran.DIFactory;
var configurator = new DIFactory(configuration);
configurator.basePath = __dirname; //DI will look for the services realtive to this path,
var di = configurator.create();

//add routes
var router = mazagran.router;

router.match('/').to('homepage.index');
router.match('/:controller/:action(/:id)');


var App = mazagran.App;
var app = new App(di, router);

//run the application!
app.run();

and that's it

Now all you need to do is add controllers and templates

Recommended file structure

These are also assumed defaults:

root/
    - server.js
    - controllers/
    - templates/
    - logs/
    - www/

Routing

Routing uses https://github.com/kieran/barista so refer to that for documentation The routing system is unique in node.js world You don't have to specify a separate route for each controller, you can use one allmighty route

router.match('/:controller/:action(/:id)');

This will match any existing controller in your application If the controller name or action doesn't exist a 404 error will be thrown

##Controllers

should look like this:

//assuming a route router.match('/:controller/:action(/:id)');

function Homepage() {

	/*
		will match /homepage/index
		name will come from either POST body or GET query ?name=Martin
	*/
	this.index = function(name) {

		var data = {
				name: name
			};

		this.view.render('index', data);
	};

	//will match /homepage/list
	this.list = function() {
		var data = [
			{id: 1, name: 'peto'},
			{id: 2, name: 'miso'},
			{id: 3, name: 'tomas'},
			{id: 4, name: 'mato'},
			{id: 5, name: 'juro'}
		];
		this.view.render('list', {persons: data});
	};

	//will match /homepage/user/1 id will be 1
	this.user = function(id) {
		this.view.render('user', {id: id});
	};
};

module.exports = Homepage;

Middleware

Mazagran is built on top of connect so it can accept any middleware compatible

just add to server.js

app.use(middleware);

default middlewares:

connect.static
connect.query
passport
quip
body-parser
connect-powered-by
connect-flash

Templating

Templating uses nunjucks engine http://jlongster.github.io/nunjucks/ Templates reside by default in templates/ directory and have extension of .html Templates support layouts, inheritance and blocks

You can generate urls in views using the url helper

<a href="{{helpers.url('main:index', {param: 'value', param2: 'value2'})}}">Main page</a>

or without parameters

<a href="{{helpers.url('main:index')}}">Main page</a>

The view engine is easily replacable it just needs to conform to the default view interface, see source

Dependency injection

Mazagran uses dependency injection https://github.com/sakren/node-dependency-injection Configuration https://github.com/sakren/node-easy-configuration

Mazagran also uses Configuration and DI for its internal services configuration

//default parameters, you can override them in your config.json
"parameters": {
		"server": {
			"host": "0.0.0.0",
			"port": 8080
		},
		"templates": {
			"path" : "./templates/",
			"defaultExtension" : "html"
		},
		"controllers": {
			"path": "./controllers"
		},
		"statics": {
			"path": "./www",
			"maxAge": 86400000
		},
		"logs": {
			"dir": "./logs"
		}
	},

default overridable services:

view
nunjucks
logger
async

Controllers and DI

You can require any service defined in DI config in your controllers by their names, they will be automatically autowired

function Homepage(view, logger) {
	console.log(view, logger);
}

Logging

Mazagran uses winston for logging By default there are 3 log files created access.log - logs accesses error.log - logs all error types info.log - logs info and debug messages

Async

Mazagran uses async library https://github.com/caolan/async to organize its code It's also available in DI container by default, so you can use it in your controllers

TODO

• implement error controller
• create sandbox
