## Motivation

This library represents a practical approach to convert the schemas used in a Mongoose model so that they can conveyed to hypermedia clients that interact with the web service.

## Installation

```

npm install mongoose-jsonschema

```

## Usage

### Adding hypermedia controls in the Mongoose model

A Mongoose model should be augmented so that the schema options contains a JSON tranformation function:

```javascript

var mongoose = require('mongoose');

var schema = new mongoose.Schema({

	...

}, {

	toJSON: {

		transform: function (doc, ret, options) {

			ret._links = {

				describedBy: {

					href: '/meta/schemas/example'

				}

			};

		}

	}

});

var model = mongoose.model('Example', schema);

```

Now, every time the model is converted to JSON, the representation will convey to the client the link that describes the schema of the document. The representation uses the [HAL](http://stateless.co/hal_specification.html) convention but other san be used as well.

### Exposing the schemas

```javascript

var express =  require('express'),

		mongoose = require('mongoose'),

		jsonSchema = require('mongoose-jsonschema').modelToJSONSchema;

var app = express();

app.get('/meta/schemas/:schema', function (req, res) {

	res.set({

		'Content-Type': 'application/schema+json'

	}).send(jsonSchema(mongoose.model(req.params.schema))).end();

});

```

## API
