Use monk in nodejs to access mongodb

Mongodb

Install mongodb

I think mannual install is a little more reliable: http://docs.mongodb.org/manual/tutorial/install-mongodb-on-os-x/

Start mongodb

$ Mongod

Connect to mogodb

$ Mongo

Mongo> use monk-app

Mongo> db. products. insert ({"name": "apple juice", "description": "good "})

WriteResult ({"nInserted": 1 })

Mongo> db. products. find (). pretty ()

{
"_ Id": ObjectId ("53b4cf8d5ef358e649ff1665 "),
"Name": "apple juce ",
"Description": "good"
}

Access mongodb with monk in nodejs

$ Mkdir monk-app

$ Cd monk-ap

Create package. json

{
"Name": "monk-app ",
"Version": "0.0.1 ",
"Private": true,
"Dependencies ":{
"Mongodb ":"*",
"Monk ":"*"
}
}

$ Npm install

Create app. js

Link to the database created earlier

Var monk = require ('monk ')
Var db = monk ('localhost: 27017/monk-demo ')

Read data:

Var monk = require ('monk ')
Var db = monk ('localhost: 27017/monk-demo ')

Var products = db. get ('products ')
Products. find ({}, function (err, docs ){
Console. log (docs)
})

[{_ Id: 53b4d3238cb4707ca35ab6f8,
Name: 'apple juice ',
Description: 'good'}]

Insert data:

Products. insert ({"name": "orange juice", "description": "just so "})

Search data:

Products. find ({"name": "apple juice"}, function (err, docs ){
Console. log (docs)
})

Create an auto-increment id in mongodb:
