    Express Contrib

    Express utilities which do not belong in core, however prove useful.

    Installation

    npm:

    $ npm install express-contrib
    

    Modules

    • Flash notification rendering (express-messages)

    Module Usage

    You may either require the specific module, for example:

    var messages = require('express-contrib/messages');
    

    or access via the main express-contrib module which is useful when utilizing many of the modules:

    var contrib = require('express-contrib');
    var messages = contrib.messages;
    

    express-messages

    The express-messages module provides flash notification rendering. To use simply assign it to a dynamic helper:

    app.dynamicHelpers({ messages: require('express-contrib/messages') });
    

    Then in a view you may output the notifications:

    <%- messages() %>
    

    Which outputs HTML as shown below:

    <div id="messages">
      <ul class="info">
        <li>Email queued</li>
        <li>Email sent</li>
      </ul>
      <ul class="error">
        <li>Email delivery failed</li>
      </ul>
    </div>
    

    express-namespace

    The express-namespace module provides namespace capabilities to express. The example below may respond to any of the following requests:

    GET /forum/12
    GET /forum/12/view
    GET /forum/12/edit
    GET /forum/12/thread/5
    DELETE /forum/12
    

    To utilize this module simply require('express-contrib'), or if you prefer to only utilize namespacing require('express-contrib/namespace'), and app.namespace() will automatically be available to you.

    Usage is as follows, simply pass a callback function and route to the method, after each callback invocation is complete, the namespace is restored to it's previous state.

    app.namespace('/forum/:id', function(){
      app.get('/(view)?', function(req, res){
        res.send('GET forum ' + req.params.id);
      });
      
      app.get('/edit', function(req, res){
        res.send('GET forum ' + req.params.id + ' edit page');
      });
    
      app.namespace('/thread', function(){
        app.get('/:tid', function(req, res){
          res.send('GET forum ' + req.params.id + ' thread ' + req.params.tid);
        });
      });
    
      app.del('/', function(req, res){
        res.send('DELETE forum ' + req.params.id);
      });
    });
    

    You can also access the current namespace via app.currentNamespace;

    express-resource

    Provides resourceful routing, for example a module or object can be defined as shown in the example below, where all methods or "actions" are optional:

    exports.index = function(req, res){
      res.send('forum index');
    };
    
    exports.new = function(req, res){
      res.send('new forum');
    };
    
    exports.create = function(req, res){
      res.send('create forum');
    };
    
    exports.show = function(req, res){
      res.send('show forum ' + req.params.id);
    };
    
    exports.edit = function(req, res){
      res.send('edit forum ' + req.params.id);
    };
    
    exports.update = function(req, res){
      res.send('update forum ' + req.params.id);
    };
    
    exports.destroy = function(req, res){
      res.send('destroy forum ' + req.params.id);
    };
    

    The id option can be specified to prevent collisions:

     exports.id = 'uid';
    
     exports.destroy = function(req, res) {
       res.send('destroy user ' + req.params.uid);
     };
    

    The app.resource() method will create and return a new Resource:

    var contrib = require('express-contrib')
      , Resource = contrib.Resource
      , app = express.createServer();
    
    app.resource('forums', require('./forum'));
    

    Actions are then mapped as follows (by default):

    GET     /forums           ->  index
    GET     /forums/new       ->  new
    POST    /forums           ->  create
    GET     /forums/:id       ->  show
    GET     /forums/:id/edit  ->  edit
    PUT     /forums/:id       ->  update
    DELETE  /forums/:id       ->  destroy
    

    NOTE: this functionality will surely grow with time, and as data store clients evolve we can provide close integration.

    express-configure

    Ever wanted to boot your Express app settings using Redis or a similar key/value store? well now it is easy, all you need to do is either require('express-configure') or require('express-contrib') and callback a function in configure():

    app.configure(function(done){
      redis.hmget('settings', function(err, obj){
        for (var key in obj) app.set(key, obj[key]);
        done();
      });
    });
    
    app.listen(3000);
