# mongojs
|
||
|
|
A wrapper around the mongodb driver [mongodb-native](https://github.com/christkv/node-mongodb-native/) for [node.js](http://nodejs.org) that tries to emulate the mongo shell as much as possible.
|
||
|
|
It is available through npm:
|
||
|
|
|
||
|
|
npm install db
|
||
|
|
|
||
|
|
DB is very simple to use:
|
||
|
|
|
||
|
|
var db = require('db').connect(databaseURL, [collections]);
|
||
|
|
|
||
|
|
Some examples of this could be:
|
||
|
|
|
||
|
|
// simple usage for a local db
|
||
|
|
var db = require('db').connect('mydb', ['mycollection']);
|
||
|
|
|
||
|
|
// the db is on a remote server (the port default to mongo)
|
||
|
|
var db = require('db').connect('example.com/mydb', ['mycollection']);
|
||
|
|
|
||
|
|
// we can also provide some credentials
|
||
|
|
var db = require('db').connect('username:password@example.com/mydb', ['mycollection']);
|
||
|
|
|
||
|
|
After we connected to can query or update the database just how we would using the mongo shell with the exception that we use a callback
|
||
|
|
|
||
|
|
// find everything
|
||
|
|
db.mycollection.find(callback);
|
||
|
|
|
||
|
|
// find everything, but sort by name
|
||
|
|
db.mycollection.find().sort({name:1}, callback);
|
||
|
|
|
||
|
|
// iterate over all whose level is greater than 90 (callback(null,null) indicates that the iteration has finished)
|
||
|
|
db.mycollection.find({level:{$gt:90}}).forEach(callback);
|
||
|
|
|
||
|
|
// find all named 'mathias' and increment their level
|
||
|
|
db.mycollection.update({name:'mathias'}, {$inc:{level:1}}, {multi:true}, callback);
|
||
|
|
|
||
|
|
// use the save function to just save a document (the callback is optional for all writes)
|
||
|
|
db.mycollection.save({created:'just now'});
|
||
|
|
|
||
|
|
