The wise MongoDB API
# monk

Monk is a tiny layer that provides simple yet substantial usability
improvements for MongoDB usage within Node.JS.

## Features

- Command buffering. You can start querying right away.
- Promises built-in for all queries. Easy interoperability with modules.
- Easy connections / configuration
- Well-designed signatures
- Improvements to the MongoDB APIs (eg: `findAndModify` supports the
`update` signature style)
- Auto-casting of `_id` in queries
- Builds on top of [mongoskin](http://github.com/guileen/node-mongoskin)

## How to use

### Connecting

#### Single server

```js
var db = require('monk')('localhost/mydb')
```

#### Replica set

```js
var db = require('monk')('localhost/mydb,192.168.1.1/mydb')
```

### Collections

#### Getting one

``js
var users = db.get('users')
// users.insert(), users.update() … (see below)
```
#### Dropping
```js
users.drop(fn);
```

### Signatures

- All commands accept the simple `data[, …], fn`. For example
- `find({}, fn)`
- `findOne({}, fn)`
- `update({}, {}, fn)` `findAndModify({}, {}, fn)`
- `findById('id', fn)`
- You can pass options in the middle: `data[, …], options, fn`
- You can pass fields to select as an array: `data[, …], ['field', …], fn`
- You can pass fields as a string delimited by spaces:
`data[, …], 'field1 field2', fn`
- To exclude a field, prefix the field name with '-':
`data[, …], '-field1', fn`

### Promises

All methods that perform an async action return a promise.

```js
var promise = users.insert({});
promise.type; // 'insert' in this case
promise.error(function(err){});
promise.on('error', function(err){});
promise.on('success', function(doc){});
promise.on('complete', function(err, doc){});
promise.success(function(doc){});
```

### Indexes

```js
users.index('name.first', fn);
users.index('email', { unique: true }); // unique
users.index('name.first name.last') // compound
users.index({ 'email': 1, 'password': -1 }); // compound with sort
users.index('email', { sparse: true }, fn); // with options
users.indexes(fn); // get indexes
users.dropIndex(name, fn); // drop an index
users.dropIndexes(fn); // drop all indexes
```

### Inserting

```js
users.insert({ a: 'b' }, function (err, doc) {
if (err) throw err;
});
```

### Casting

To cast to `ObjectId`:

```js
users.id('hexstring') // returns ObjectId
users.id(obj) // returns ObjectId
```

### Finding

#### Many

```js
users.find({}, function (err, docs){});
```

#### By ID

```js
users.findById('hex representation', function(err, doc){});
users.findById(oid, function(err, doc){});
```

#### Single doc

`findOne` also provides the `findById` functionality.

```js
users.findOne({ name: 'test' }).on('success', function (doc) {});
```

#### And modify

```js
users.findAndModify({ query: {}, update: {} });
users.findAndModify({ _id: '' }, { $set: {} });
```

#### Streaming

Note: `stream: true` is optional if you register an `each` handler in the
same tick. In the following example I just include it for extra clarity.

```js
users.find({}, { stream: true })
.each(function(doc){})
.error(function(err){})
.success(function(){});
```

### Query debugging

If you wish to see what queries `monk` passes to the driver, simply leverage
[debug](http://github.com/visionmedia/debug):

```bash
DEBUG="monk:queries"
```

To see all debugging output:

```bash
DEBUG="monk:*"
```
