Introduction

Node.js is a popular JavaScript runtime environment that allows developers to build scalable and high-performance applications. Express.js is a framework built on top of Node.js that provides a set of features for building web applications. MongoDB is a NoSQL database that allows developers to store and retrieve data in a flexible and scalable manner. In this article, we will show you how to build a blog using Node.js, Express.js, and MongoDB, and deploy it on GitHub.

Prerequisites

Before we start, make sure you have the following installed:

• Node.js and npm
• MongoDB
• A text editor or IDE
• Git

Creating a New Node.js Project

First, let’s create a new directory for our project:

Next, navigate to the directory and run the following command to initialize a new Node.js project:

npm init

Follow the prompts and enter the necessary information for your project.

Installing Dependencies

We will be using the following dependencies for our project:

• express
• mongoose
• ejs
• body-parser

You can install them by running the following command:

npm install express mongoose ejs body-parser --save

Setting Up MongoDB

Make sure that MongoDB is running on your system. You can start it by running the following command:

mongod

In your project directory, create a file called db.js. This file will contain the code to connect to MongoDB:

To connect to MongoDB, we need to use the mongoose library. In db.js, add the following code:

const mongoose = require('mongoose');mongoose.connect('mongodb://localhost:27017/blog', {    useNewUrlParser: true,    useUnifiedTopology: true}).then(() => console.log('Connected to MongoDB'))  .catch(err => console.error('Could not connect to MongoDB', err));module.exports = mongoose;

This code connects to a local MongoDB instance and creates a new database called blog.

Creating Models

We will be creating two models for our blog: Post and User. In your project directory, create a folder called models. Then, create a file called post.js in the models folder:

In post.js, add the following code:

const mongoose = require('../db');const postSchema = new mongoose.Schema({    title: String,    content: String,    author: { type: mongoose.Schema.Types.ObjectId, ref: 'User' },    createdAt: { type: Date, default: Date.now }});const Post = mongoose.model('Post', postSchema);module.exports = Post;

This code defines the schema for a blog post and creates a model called Post.

Similarly, create a file called user.js in the models folder:

In user.js, add the following code:

const mongoose = require('../db');const userSchema = new mongoose.Schema({    name: String,    email: String,    password: String});const User = mongoose.model('User', userSchema);module.exports = User;

This code defines the schema for a user and creates a model called User.

Creating Routes

We will be creating the following routes for our blog:

• GET /: displays a list of all blog posts
• GET /posts/:id: displays a single blog post
• GET /new: displays a form to create a new blog post
• POST /new: creates a new blog post
• GET /login: displays a login form
• POST /login: logs in a user
• GET /logout: logs out a user

Create a file called routes.js in your project directory. In routes.js, add the following code:

const express = require('express');const router = express.Router();const Post = require('./models/post');const User = require('./models/user');const bodyParser = require('body-parser');const session = require('express-session');router.use(bodyParser.urlencoded({ extended: true }));router.use(session({    secret: 'secret',    resave: false,    saveUninitialized: true}));router.get('/', async (req, res) => {    const posts = await Post.find().populate('author');    res.render('index', { posts });});router.get('/posts/:id', async (req, res) => {    const post = await Post.findById(req.params.id).populate('author');    res.render('post', { post });});router.get('/new', (req, res) => {    if (!req.session.user) {        return res.redirect('/login');    }    res.render('new');});router.post('/new', async (req, res) => {    const post = new Post({        title: req.body.title,        content: req.body.content,        author: req.session.user    });    await post.save();    res.redirect('/');});router.get('/login', (req, res) => {    res.render('login');});router.post('/login', async (req, res) => {    const user = await User.findOne({        email: req.body.email,        password: req.body.password    });    if (!user) {        return res.redirect('/login');    }    req.session.user = user._id;    res.redirect('/');});router.get('/logout', (req, res) => {    req.session.destroy();    res.redirect('/');});module.exports = router;

This code defines the routes for our blog. We use the body-parser library to parse request bodies, and the express-session library to manage user sessions.

Creating Views

We will be using the ejs template engine to create our views. In your project directory, create a folder called views. Then, create a file called index.ejs in the views folder:

<% for (let post of posts) { %>    <h2><a href=/posts/<%= post._id %>><%= post.title %></a></h2>    <p>by <%= post.author.name %></p>    <p><%= post.content.substring(0, 100) %>...</p><% } %>

This code displays a list of all blog posts.

Similarly, create a file called post.ejs in the views folder:

<h2><%= post.title %></h2><p>by <%= post.author.name %></p><p><%= post.content %></p>

This code displays a single blog post.

Finally, create a file called new.ejs in the views folder:

<% if (!user) { %>    <p>Please <a href=/login>log in</a> to create a new post.</p><% } else { %>    <form method=post>        <div>            <label for=title>Title:</label>            <input type=text id=title name=title>        </div>        <div>            <label for=content>Content:</label>            <textarea id=content name=content></textarea>        </div>        <button type=submit>Create</button>    </form><% } %>

This code displays a form to create a new blog post.

Creating App.js

Create a file called app.js in your project directory. In app.js, add the following code:

const express = require('express');const app = express();const routes = require('./routes');const path = require('path');app.set('view engine', 'ejs');app.set('views', path.join(__dirname, 'views'));app.use(express.static(path.join(__dirname, 'public')));app.use('/', routes);app.listen(3000, () => {    console.log('Server started on port 3000');});

This code sets up our application by setting the view engine to ejs, setting the views directory to views, serving static files from the public directory, and using the routes defined in routes.js.

Deploying to GitHub

To deploy our blog to GitHub, we need to create a new repository and push our code to it:

• Create a new repository on GitHub
• Initialize a new Git repository in your project directory by running the following command:

git init

• Add your files to the repository by running the following command:

git add .

• Commit your changes by running
  

  Introduction: Understanding the Basics of Building a Blog with Node.js Express and MongoDB Github

  If you’re looking to build a blog with a powerful and modern tech stack, Node.js Express and MongoDB Github are two technologies that you should consider. Node.js Express is a lightweight and flexible web application framework for Node.js, while MongoDB Github is a highly scalable NoSQL database. Together, these technologies can help you build a fast, reliable, and scalable blog that can handle complex data structures.This tutorial will provide a step-by-step guide on how to build a blog using Node.js Express and MongoDB Github. We’ll cover everything from setting up your development environment to integrating the front-end with the back-end. You’ll also learn how to secure your blog with authentication and authorization, and how to manage user comments with CRUD operations.

  Setting Up the Environment for Building a Blog with Node.js Express and MongoDB Github

  Before we get started with building our blog, we need to set up our development environment. This involves installing the necessary dependencies and configuring our environment to work seamlessly with Node.js Express and MongoDB Github.In this section, we’ll guide you through the process of setting up your environment. We’ll cover everything from installing Node.js and MongoDB to creating a new Node.js Express project and configuring your database connection.

  Installing Node.js and MongoDB

  The first step in setting up your environment is to install Node.js and MongoDB. Node.js is a JavaScript runtime that allows you to run JavaScript code outside of a browser, while MongoDB is a NoSQL database that allows you to store and retrieve complex data structures.To install Node.js, simply visit the official Node.js website and download the latest version for your operating system. Once downloaded, follow the installation instructions to complete the installation process.To install MongoDB, visit the official MongoDB website and download the appropriate version for your operating system. Once downloaded, follow the installation instructions to complete the installation process.

  Creating a New Node.js Express Project

  Now that we have installed Node.js and MongoDB, we can create a new Node.js Express project. To create a new project, open up your terminal or command prompt and run the following command:“`$ mkdir my-blog$ cd my-blog$ npm init“`The first command creates a new directory called my-blog, while the second command changes your working directory to my-blog. The third command initializes a new Node.js project and creates a package.json file in your project directory.

  Installing Required Dependencies

  Now that we have created a new Node.js Express project, we need to install the necessary dependencies. To install the required dependencies, run the following command in your terminal or command prompt:“`$ npm install express mongoose body-parser passport passport-local express-session ejs –save“`This command will install the following dependencies:- Express: A lightweight and flexible web application framework for Node.js- Mongoose: A MongoDB object modeling tool designed to work in an asynchronous environment- Body-parser: A middleware that parses incoming request bodies in a middleware before your handlers- Passport: A middleware for authentication- Passport-local: A Passport strategy for authenticating with a username and password- Express-session: A session middleware for Express- Ejs: A templating engine for Node.js

  Configuring Your Database Connection

  Now that we have installed the necessary dependencies, we need to configure our database connection. To do this, create a new file called db.js in your project directory and add the following code:“`const mongoose = require(‘mongoose’);mongoose.connect(‘mongodb://localhost/my-blog’, { useNewUrlParser: true }) .then(() => console.log(‘MongoDB Connected’)) .catch(err => console.log(err));“`This code imports the Mongoose module and connects to a local MongoDB instance running on your machine. You can replace my-blog with the name of your database.

  Creating and Configuring a Node.js Express Server

  Now that we have set up our environment and installed the necessary dependencies, we can start creating our Node.js Express server. In this section, we’ll guide you through the process of creating a new server from scratch. We’ll cover everything from adding routes to configuring your server to work seamlessly.

  Adding Routes

  The first step in creating a Node.js Express server is to add routes. Routes define the URL paths that your server will respond to, and they specify the function that will handle the requests for each path.To add routes, create a new file called routes.js in your project directory and add the following code:“`const express = require(‘express’);const router = express.Router();router.get(‘/’, (req, res) => { res.send(‘Hello World!’);});module.exports = router;“`This code creates a new router object and defines a single route for the root URL path (/). When a user visits the root URL path, the server will respond with the message Hello World!.

  Creating Template Files

  Now that we have added some routes, we need to create some template files that our server can use to generate dynamic content. To do this, create a new directory called views in your project directory, and create a new file called index.ejs inside the views directory. Add the following code to the index.ejs file:“`

  <%= message %>

  “`This code defines a basic HTML template with a title and a message. The title and message are placeholders that will be replaced with dynamic content later on.

  Configuring Your Server

  Now that we have added some routes and created some template files, we need to configure our server to work seamlessly with Node.js Express. To do this, create a new file called app.js in your project directory and add the following code:“`const express = require(‘express’);const bodyParser = require(‘body-parser’);const session = require(‘express-session’);const passport = require(‘passport’);const LocalStrategy = require(‘passport-local’).Strategy;const mongoose = require(‘mongoose’);const db = require(‘./db’);const routes = require(‘./routes’);const app = express();const port = process.env.PORT || 3000;app.use(bodyParser.urlencoded({ extended: false }));app.use(bodyParser.json());app.use(session({ secret: ‘secret’, resave: false, saveUninitialized: false,}));app.use(passport.initialize());app.use(passport.session());passport.use(new LocalStrategy({ usernameField: ’email’, passwordField: ‘password’,}, (email, password, done) => { User.findOne({ email: email }, (err, user) => { if (err) { return done(err); } if (!user) { return done(null, false); } if (!user.verifyPassword(password)) { return done(null, false); } return done(null, user); });}));passport.serializeUser((user, done) => { done(null, user.id);});passport.deserializeUser((id, done) => { User.findById(id, (err, user) => { done(err, user); });});app.use(‘/’, routes);app.listen(port, () => { console.log(`Server started on port ${port}`);});“`This code imports the necessary modules and sets up the middleware for our server. It also defines a new Passport strategy for local authentication and configures the Passport middleware to use it. Finally, it sets up the server to listen on a specific port (in this case, port 3000).

  Introducing MongoDB Github

  Before we proceed with building our blog, let’s take a closer look at MongoDB Github. MongoDB Github is a highly scalable NoSQL database that can store and retrieve complex data structures. It is designed to work in an asynchronous environment and can handle large volumes of data.MongoDB Github stores data in collections, which are similar to tables in a relational database. Each collection contains multiple documents, which are analogous to rows in a table. Documents are stored in BSON format, which is a binary representation of JSON.MongoDB Github supports a wide range of data types, including strings, numbers, booleans, arrays, and objects. It also supports complex data types such as dates, regular expressions, and binary data.

  Installing and Configuring MongoDB Github with Node.js Express

  Now that we have introduced MongoDB Github, let’s move on to installing and configuring it with Node.js Express. In this section, we’ll guide you through the process of connecting your server to a MongoDB database and performing database operations.

  Connecting to MongoDB

  The first step in using MongoDB with Node.js Express is to connect to a MongoDB database. To do this, open up your db.js file and add the following code:“`const mongoose = require(‘mongoose’);mongoose.connect(‘mongodb://localhost/my-blog’, { useNewUrlParser: true }) .then(() => console.log(‘MongoDB Connected’)) .catch(err => console.log(err));“`This code connects to a local MongoDB instance running on your machine and logs a message to the console if the connection is successful. You can replace my-blog with the name of your database.

  Creating Database Collections

  Now that we have connected to a MongoDB database, we can create database collections. To do this, create a new file called models.js in your project directory and add the following code:“`const mongoose = require(‘mongoose’);const postSchema = new mongoose.Schema({ title: String, content: String, author: String, created_at: { type: Date, default: Date.now },});module.exports = { Post: mongoose.model(‘Post’, postSchema),};“`This code defines a new Mongoose schema for a post collection. The schema defines four fields: title, content, author, and created_at. It also exports a new Mongoose model for the post collection.

  Performing Database Operations

  Now that we have created a database collection, we can perform database operations such as creating, reading, updating, and deleting posts. To do this, open up your routes.js file and add the following code:“`const express = require(‘express’);const router = express.Router();const { Post } = require(‘./models’);router.get(‘/’, (req, res) => { Post.find({}, (err, posts) => { if (err) { res.status(500).send(err); } else { res.render(‘index’, { title: ‘My Blog’, posts: posts }); } });});router.get(‘/posts/new’, (req, res) => { res.render(‘new_post’, { title: ‘New Post’ });});router.post(‘/posts’, (req, res) => { const { title, content, author } = req.body; const post = new Post({ title, content, author }); post.save((err, post) => { if (err) { res.status(500).send(err); } else { res.redirect(‘/’); } });});module.exports = router;“`This code defines three routes for creating, reading, and updating posts. The first route retrieves all the posts from the post collection and renders them on the index page. The second route renders a form for creating a new post. The third route creates a new post in the post collection.

  Building the Front-end for Your Blog with HTML, CSS, and JavaScript
