Xylem NPM | npm.io

Xylem

Xylem provides a mechanism to persist and manipulate data on the file system, memory or a database server.

Differently from other ORM/ODM tools out there, Xylem allows you to reference and combine data from different sources, making it the ultimate storage abstraction library to back a REST server, a CMS or any other data driven application.

Getting started

Installing Xylem

$ npm install xylem

Installing an adapter

$ npm install xylem-mongodb

Creating connections

var Server = require('xylem');
var MongoDB = require('xylem-mongodb');

var server = new Server();

server
  .adapter('mongodb', MongoDB)
  .connection('database', 'mongodb://localhost/xylem');

Creating models

server.model('contact', {
  connection: 'database',
  fields: {
    id: 'string',
    name: 'string',
    email: 'string'
  },
  key: 'id'
});

Storing and retrieving data

var Contact = server.model('contact');

var john = new Contact({
  id: 1,
  name: 'John',
  email: 'john@example.com'
});

john.save(function (error, john) {
  console.log(john);

  // Get a list of contacts.
  Contact.list({}, function (error, contacts) {
    console.log(contacts);
  });
});
