## 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
