What's it look like?

How to use it

This section contains a task-based set of instructions on how to use stork for your CouchDB ODM needs. It models a simple reservation system.

Install stork for your project

Follow the instructions, below, in Installing.

require stork

Yeah, that seems pretty self evident.

var odm = require('stork');

Declare an entity

Let's declare an entity that stork knows about. When we declare entities, we provide a name and, if we want, a function that will describe a schema for us. We can define arrays, booleans, children, date/times, numbers, objects with their own schema, references to other documents, strings, timestamps, and views.

stork uses the schema of the object to provide validation for you. You can save invalid documents to CouchDB, if you'd like. stork does not judge. stork just delivers.

var event = odm.stork('event', function() {
  this.string('name', { required: true, maxLength: 100 });
  this.string('description', { required: true });
  this.object('venue', { required: true }, function() {
    this.string('url', { format: 'url' });
    this.string('name');
    this.string('address', { required: true });
    this.string('city');
    this.string('state');
    this.string('zip', { format: /\d{5}/ });
  });
 
  this.number('maximumGuests', { required: true });
  this.boolean('cancelled');
 
  this.array('rsvps');
 
  this.timestamps();
});

Installing

Because we're still developing, this ain't on npm, yet. So, right now, you can run the following commands to include it in your project.

git clone https://github.com/realistschuckle/stork.git
cd stork
npm link
