nodetoo

Express + MVC = {nodetoo}

{nodetoo}

Inspired by Express mvc example, nodetoo is a MVC framework built on top of Express.

$ npm install -g nodetoo

Assuming you have created a project with Express, please refer here for the guide.

  • Create the app
$ cd /project
$ npm install nodetoo
$ nodetoo
  • Bootstrap nodetoo:
var express = require('express');
var nodetoo = require('nodetoo');
var app = express();
 
app.configure(function(){
  ...
  
  // boostrap nodetoo 
  nodetoo.bootstrap(app);
  
  app.use(app.router);
  ...
});
 
// remove any existing route 
...
 
app.listen(3000);
  • Start the server:
$ node app

nodetoo only work on the app/ and config/ folder

app/
  controllers/
    home/
      index.js
  models/
      user.js
  views/
    home/
      index.jade
config/
    injections/
    plugins/
    routes.js
    setting.js

Each js file under models/ is a model, nodetoo will bootstrap all of them automatically.

models/
  user.js
  post.js
  comment.js

Each folder under controllers/ is a controller, index.js represent the js file.
Let's take a look at the controllers/home/index.js file.

exports.actions = {
  
  indexfunction (reqres) {
    res.render('home/index');
  },
 
  aboutfunction (reqres) {
    res.render('home/about');
  },
}

Filters are middlewares that run before the action function.

Exports as a function before.

exports.before = function (reqresnext) {
    
  console.log('[BEFORE]: ' + req.url);
  next();
}
 
exports.actions = {
  
  indexfunction (reqres) {
    res.render('home/index');
  }
}

Exports as an object before, support injection.

exports.before = {
  
  all: [
    {
      middlewares: ['logger'],
      except: ['login']
    }
  ],
  only: [
    { 
      middlewares: ['watcher'],
      actions: ['login']
    }
  ]
};
All actions will use `logger` except `login` action.
Only `login` action will use `watcher`.

Define at action and it will be given priority.

exports.actions = {
  
  index: {
    before: ['watcher', 'logger'],
    actionfunction (reqres) {
      res.render('home/index');
    }
  }
}

Here is the injections

config/
    injections/
        logger.js
        watcher.js

Roles are use in Authentication process.

Exports as an object roles.

exports.roles = {
 
  all: [
    {
      roles: ['*'],
      except: ['login']
    }
  ],
  only: [
    {
      roles: ['user'],
      actions: ['createUser']
    },
    {
      roles: ['admin'],
      actions: ['createUser']
    },
  ]
};
All actions has role `*` except `login` action.
Only `createUser` action has role `user`.
Only `createUser` action has role `admin`.

PS: Role * apply to any roles, but it depend on how you write the authenticator.

Define at action and it will be given priority.

exports.actions = {
  
  index: {
    roles: ['*'],
    actionfunction (reqres) {
      res.render('home/index');
    }
  }
}

Action is a controller method and represent as [controller].[method].

home.index
home.about

Routes are defined in the config/routes.js file

module.exports = [
    ['/'                        ,'get'  ,'home.index']
  , ['/about'                   ,'get'  ,'home.about']
]

When roles is configured, {nodetoo} will ask for an authenticator via injection.

config/
    injections/
        authenticator.js
module.exports = function(roles) {
  return function (reqresnext) {
    // retrieve user from session 
    var user = req.session.user;
    if (user === undefined) {
      res.status(401).render('401');
    } 
    // asterisk skip authorization 
    else if (!_.contains(roles, '*') 
          && !_.intersection(user.roles, roles).length > 0) {
      res.status(401).render('401');
    } else next();
  }
}

But how you write the authenticator, it is really up to you. Please refer to the example.

Any module under injections/ folder can be inject with the module filename without the extension.

config/
    injections/
        module.js
var module = inject('module');

PS: Actually nothing special with the injection, it is just a global function as require.

Clone the nodetoo repo, then install the dev dependencies:

$ git clone git://github.com/fliptoo/nodetoo.git --depth 1
$ cd nodetoo
$ npm install

and run whichever examples you want:

$ cd examples/basic
$ node app
