node-restful

Create awesome APIs using express.

var express = require('express'),
    restful = require('node-restful'),
    mongoose = restful.mongoose;
var app = express();

app.use(express.bodyParser());
app.use(express.query());

mongoose.connect("mongodb://localhost/resources");

var Resource = app.resource = restful.model('resource', mongoose.Schema({
    title: 'string',
    year: 'number',
  }))
  .methods(['get', 'post', 'put', 'delete']);

Resource.register(app, '/resources');

app.listen(3000);

Registers the following routes:

GET /resources
GET /resources/:id
POST /resources
PUT /resources/:id
DELETE /resources/:id

which do exactly what you think they do!

The best part is that restful.model returns a Mongoose model, so you can interact with it the same way that you're already accustomed to! (i.e. new Resource, Resource.findById, etc.)

Support

This library is currently supported through complaint driven development, so if you see something, have a feature request, open an issue and if it seems to jive with the mission of the library, I'll prioritize it.

Install

npm install node-restful

Usage

There is a good example application under examples/movies.

I will also show some features and use cases for them, how to set up routes, etc.

API

There are a few functions that are available after we register the mongoose schema. The first one we already saw.

.methods([...]) takes a list of methods that should be available on the resource. Future calls to methods will override previously set values To disallow delete operations, simply run

Resource.methods(['get', 'post', 'put'])

We can also run custom routes. We can add custom routes by calling .route(path, handler)

Resource.route('recommend', function(req, res, next) {
  res.send('I have a recommendation for you!');
});

This will set up a route at /resources/recommend, which will be called on all HTTP methods. We can also restrict the HTTP method by adding it to the path:

Resource.route('recommend.get', function(req, res, next) {
   res.send('GET a recommendation');
});
Resource.route('recommend', ['get', 'put', 'delete'], function(req, res, next) { ... });

Or do some combination of HTTP methods.

Now. Lets say we have to run arbitrary code before or after a route. Lets say we need to hash a password before a POST or PUT operation. Well, easy.

Resource.before('post', hash_password)
  .before('put', hash_password);
      
function hash_password(req, res, next) {
  req.body.password = hash(req.body.password);
  next();
}

Boy. That was easy. What about doing stuff after request, but before its sent back to the user? Restful stores the bundle of data to be returned in res.locals (see express docs). res.locals.status_code is the returned status code and res.locals.bundle is the bundle of data. In every before and after call, you are free to modify these are you see fit!

Resource.after('get', function(req, res, next) {
  var tmp = res.locals.bundle.title; // Lets swap the title and year fields because we're funny!
  res.locals.bundle.title = res.locals.bundle.year;
  res.locals.bundle.year = tmp;
  next(); // Don't forget to call next!
});
    
Resource.after('recommend', do_something); // Runs after all HTTP verbs

Now, this is all great. But up until now we've really only talked about defining list routes, those at /resources/route_name. We can also define detail routes. Those look like this

Resource.route('moreinfo', {
    detail: true,
    handler: function(req, res, next) {
        // req.params.id holds the resource's id
        res.send("I'm at /resources/:id/moreinfo!")
    }
});

I don't think this is the prettiest, and I'd be open to suggestions on how to beautify detail route definition...

And that's everything for now!
