nedb-promise
============

A promise wrapper for [NeDB](https://github.com/louischatriot/nedb).

Installation
============

Install with NPM:

`$ npm i --save nedb-promise`

Usage
=====

Example using ES7 async/await:
```javascript
import datastore from 'nedb-promise'

async function doDatabaseStuff() {
let DB = datastore({
// these options are passed through to nedb.Datastore

filename: 'my-db.json',

autoload: true // so that we don't have to call loadDatabase()
})

await DB.insert([{
num: 1, alpha: 'a'
}, {
num: 2, alpha: 'b'
}])

let document = await DB.findOne({ num: 1 })

// use NeDB cursors:
let documents = await DB.cfind({})
.projection({ num: 1, _id: 0 })
.exec()
}

doDatabaseStuff()
```

API
===

## datastore(options)

Returns an object that proxies to an internal `nedb.Datastore` instance (`options` are passed through to the NeDB constructor), with promisified methods.

It also includes extension methods `cfind(...)`, `cfindOne(...)`, and `ccount(...)` that return promisified cursors, so that you may do:

```javascript
let results = await myDataStore.cfind({ moo: 'goo' })
.projection({ moo: 1, _id: 0 }) // see NeDB cursor methods
.exec()
```

## datastore.fromInstance(nedbInstance)

Use this method if you already have a NeDB instance that you want to wrap with the promisified methods.

Testing
=======

Run tests with mocha (after building):

```
$ mocha test.js
```
