How to make a project with Node.js & MongoDB (CRUD) - Part 1

In this tutorial we will create a simple CRUD application (Create, Read, Update & Delete) with Node.js and MongoDB. We will use the Express framework and support of libraries Mongoose to handle MongoDB databases.




We need to have installed:

          - Node.js      (If you don't have it click here)
          - Express      (If you don't have it click here)
          - MongoDB (If you don't have it click here)

Now, we will create our project:



Create the project

1 - Open your terminal and headed to the directory where we want to create our project

2 - Write in the terminal:    $ express crudApp  

3 - Headed to the project folder and opened the file "package.json" and insert a new line in dependecies:

"dependencies": {     "express": "3.4.8",     "jade": "*",     "mongoose": "*"   }

this is the module that will allow us to chat communications

4 - choose de folder of the proyect in the terminal:    $  cd crudApp  

5 - install dependencies, write in the terminal:   $ npm install  

Create the DataBase

1 - Headed to the project folder and create a new folder called "Data".

2 -  Open your terminal and create de new DataBase, write: 

   $ mongod --dbpath  folder_data_url*     *change folder_data_url for your folder data url

 Warning: You can't close this terminal window.

Create the server

Open the file "app.js" and write:

1 - Below "var app = express();" write:

// ... code var app = express(); // require the library mongoose mongoose = require('mongoose'); // Connect with our database mongoose.connect('mongodb://localhost/db_crudApp'); // Create the model of the database var Schema = mongoose.Schema var info = new Schema({ name: String, email: String }); // create de object of the model var info = mongoose.model('info',info); //... code

2 - Create the routes, add this code below "app.get('/users', user.list);":

// ... code app.get('/', routes.index); app.get('/users', user.list); app.get('/contacts',function(req, res){ info.find({},function(err,data){   res.render('contacts', {     title: 'Contacts',   data: data   }); }); }); app.post('/contacts',function(req, res){ newinfo = new info({ name: req.body.name, email: req.body.email}); newinfo.save(function(err){ if (err) {throw error;} else {res.redirect('/contacts');} }); }); // ... code

Create the view

Create a new jade file "views/contacts.jade" and write this:

becareful with the tabulated, jade is very sensitive with them

Run de App

Write in the terminal:   $ node app  and open your browser in localhost:3000/contacts

We can see de form to add a new contact and all the contacts.
