## README

# deep-check

Check that properties of a deeply-nested object exist.

## install

```bash
$ npm install deep-check
```

## usage

The schema used to check if values are present can be itself a deeply nested object:

```javascript
var deepCheck = require('deep-check')
var data = {
  fruit:{
    citrus:{
      lemons:10,
      oranges:12
    }
  },
  orders:{
    settings:{
      id:12
    }
  }
}

var schema = {
  fruit:{
    citrus:{
      lemons:true,
      weight:true
    }
  },
  orders:{
    settings:true,
    history:true
  }
}

var missing = deepCheck(data, schema)

console.log(missing)

// ['fruit.citrus.weight', 'orders.history']
```

Or you can use an array with dot-notation:

```javascript
var schema = [
  'fruit.citrus.lemons',
  'fruit.apples',
  'orders.settings',
  'orders.history'
]

var missing = deepCheck(data, schema)

console.log(missing)

// ['fruit.apples', 'orders.history']
```
