README

entropy is a simple RESTful server in front of a MongoDB instance using node.js, Express and Mongoose.

DEPENDENCIES

• node.js
• Express
• Mongoose

INSTALLATION

Clone the Github repository. Update the vendor libraries:

$> git clone git://github.com/pminnieur/entropy.js.git
$> sh update_vendors.sh

You can run an entropy instance just by starting it with the node command:

node entropy.js

CONFIGURATION

Copy the config.json.sample file to config.json and modify it to fit your needs.

USAGE

You can use entropy without any models, but I recommend to have a schema for each of your models. You can put your Mongoose models in the /models directory. Here's an example of an simple user model:

// models/user.js
var mongoose = require("mongoose").Mongoose;

mongoose.model("user", {
  properties: ["username", "email"],
  cast: {
    username: String,
    email: String
  },
  indexes: ["username", "email"]
});

That's it. You can now find, read, create, modify and remove user objects via REST, just by calling the appropriate URLs. The routing schema is very simple:

Find

GET /:collection

Read

GET /:collection/:id

Create

POST /:collection?collection[field1]=value1&collection[field2]=value2...

Modify

POST /:collection/:id?collection[field1]=value1&collection[field2]=value2...

Remove

DELETE /:collection/:id

NOTE: the collection[] array must be named like the model you want to access, thus for creating or modifying a user you must use it like this: ?user[username]=foo&user[email]=bar

Finding documents

You can specifiy what you want to find with the following parameters:

Querying

GET /:collection?query[field1]=value1&query[field2]=value2&...

Sorting

GET /:collection?order[field1]=asc|desc&order[field2]=asc|desc&...

Pagination

GET /:collection?limit=5&offset=5

CUSTOMIZATION

If you want to overload the default behavior of the REST controllers, simply put your own in the /controllers directory. Here's an example for a customized user controller which removes users' email address from the response:

// controllers/user.js
var app = modules.parent.exports.app,
    db = modules.parent.exports.db;
    
app.get('/user', function(req, res) {
  db.model('user').find().all(function(users) {
    ret = [];
    users.forEach(function(user) {
      user = user.toObject();
      delete user.email;
      ret.push(user);
    });

    res.header('Content-Type', 'application/json');
    res.send(ret, 200);
  })
});
