With the increasing need for dynamic and interactive web applications, having a versatile content management system (CMS) in place is crucial. In this tech blog post, we will explore how to build a CMS using Express.js, a popular Node.js web application framework.

Why Express.js?

Express.js provides a powerful and flexible framework for building web applications. It is lightweight, easy to understand, and offers a wide range of features and middleware. Leveraging Express.js for building a CMS allows us to quickly prototype, develop, and deploy web applications with scalable backend infrastructure.

Getting Started

To get started, make sure you have Node.js installed on your machine. This will include npm, the package manager for Node.js.

Setting Up the Project

1. Create a new directory for your project and navigate to it using the terminal or command prompt.
2. Initialize a new Node.js project by running the command npm init and following the instructions.
3. Install Express.js by running npm install express.
4. Create an app.js or index.js file and require Express.js:

const express = require('express');
const app = express();

Creating Routes

Routing is an essential part of building a CMS. It allows us to handle different URL paths and execute specific actions based on them. Let’s create a basic route example:

app.get('/', (req, res) => {
  res.send('Hello, CMS!');
});

app.get('/posts', (req, res) => {
  res.send('All Posts');
});

Templating Engine

To dynamically render web pages, we need to employ a templating engine. Pug (formerly known as Jade) is a popular choice.

1. Install Pug by running npm install pug.

2. Set the view engine to Pug in your Express application:

app.set('view engine', 'pug');

1. Create a views directory and add a layout.pug file with the basic structure of your website:

html
  head
    title My CMS
  body
    block content

Creating Views

Next, let’s create our first view file, index.pug, which will display the homepage:

extends layout

block content
  h1 Welcome to the CMS!
  p This is the homepage.

Serving Static Files

In a CMS, we often need to serve static files like stylesheets, images, or JavaScript files. Express.js provides a built-in middleware for this purpose. To serve static files from a public directory, add the following line:

app.use(express.static('public'));

Running the Application

To start the Express.js server and run the CMS, add the following code at the end of your app.js or index.js file:

const port = 3000;
app.listen(port, () => {
  console.log(`CMS is running on http://localhost:${port}`);
});

Save all the changes and run the application using the command node app.js or node index.js. Open your browser and visit http://localhost:3000 to see the CMS homepage.

Conclusion

In this blog post, we learned how to build a CMS using Express.js. We touched upon setting up the project, creating routes, using a templating engine, serving static files, and running the application. With Express.js, you can create a powerful and scalable CMS to manage and deliver content in a dynamic and efficient way.
