Tute 11: MongoDB, express, saving data in database - ariffira/node-basic GitHub Wiki

This tute will explain:

• how to connect mongodb easily in nodejs app/ express app
• creating schemas and model(using mongoose)
• data storing/saving

Step 01: Connecting MongoDB using mongoose to your express APP:

// add mongoose package
const mongoose = require('mongoose');

Connect mongoose:

mongoose.connect('mongodb://localhost/yourDataBaseName');

Step 02: Lets create a Schema for our user model for the registration form

models/user.js

add this code their:

// add mongoose package
const mongoose = require('mongoose');

// add mongoose Schema object
const Schema = mongoose.Schema;

//create a new Schema for user
const userSchema = new Schema({
    firstname: String,
    lastname: String,
    email: String,
    password: String,
    createdAt: Date
});

// make new user Schema as a model for use
// model(function name for model, schema data)
const User = mongoose.model('User', userSchema);

// make it usable to the application
module.exports = User;

So far model is ready for action ;)

Step 03: Use your model in route and save data on registration

// add model user in app.js
const User = require('./models/user');

// posting resgitration form data to save in MongoDB
app.post('/registration', (req, res) => {
    let postData = req.body;
    console.log(postData);
    // create a new user object as like your user schema
    let newUser = new User({
        firstname: req.body.firstname,
        lastname: req.body.lastname,
        email: req.body.email,
        password: req.body.password,
        createdAt: Date.now()
    });

    // Save the user to database
    newUser.save(err => {
        if(err) throw err;
        console.log('A new User Saved to Database!');
    });
    res.redirect('/signin');
});

So now you can save your data... great. Check it using Robo mongo or from terminal.
