A promise wrapper for NeDB.
Install with NPM:
$ npm i --save nedb-promise
Example using ES7 async/await:
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()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:
let results = await myDataStore.cfind({ moo: 'goo' })
.projection({ moo: 1, _id: 0 }) // see NeDB cursor methods
.exec()Use this method if you already have a NeDB instance that you want to wrap with the promisified methods.
Run tests with mocha (after building):
$ mocha test.js
