Introduction
If you are a developer, you know that hosting frontend and backend on separate servers can be complex and time-consuming. This is where hosting both on the same server comes in handy. By doing so, you can streamline your hosting infrastructure and improve your website’s performance.
However, hosting both on the same server is not without risks. If your server goes down, your entire website will be offline. Also, if you host multiple websites on the same server, a security breach in one website can affect all the other websites.
Therefore, before hosting your frontend and backend on the same server, it is important to consider the advantages and disadvantages of this approach. Let’s dive into it.
Pros and Cons of Hosting Frontend and Backend on Same Server
Pros:
Pros |
Description |
|---|---|
Cost-effective |
Hosting both frontend and backend on the same server can significantly reduce your hosting costs. |

Since the communication between frontend and backend is faster, your website’s performance will improve. |
Easier maintenance |
With both frontend and backend hosted on the same server, you can easily manage your hosting infrastructure. |
Cons:
Cons |
Description |
|---|---|
Security risks |
Hosting both frontend and backend on the same server increases the risk of security breaches. |
Single point of failure |
If your server goes down, your entire website will be offline. There is no redundancy. |
Difficult to scale |
Hosting both frontend and backend on the same server can make it difficult to scale your website as your traffic grows. |
As you can see, hosting frontend and backend on the same server has its advantages and disadvantages. You need to carefully consider your requirements before deciding on this approach.
Requirements for Hosting Frontend and Backend on Same Server
Before you get started, you need to ensure that your server meets the following requirements:
- A web server such as Apache or Nginx
- Node.js installed on the server
- A database server such as MySQL or MongoDB
- SSH access to the server
- A domain name and a valid SSL certificate
If your server does not meet these requirements, you need to install the necessary software and configure them accordingly. We will guide you through the process in the following sections.
Setting Up a Web Server
Step 1: Installing Apache
The first step is to install Apache on your server. You can do this by running the following command:
sudo apt-get updatesudo apt-get install apache2Once the installation is complete, you can verify that Apache is running by navigating to your server’s IP address in a web browser. You should see the Apache default page.
Step 2: Configuring Virtual Hosts
The next step is to configure virtual hosts to serve your website. This allows you to host multiple websites on the same server. To do this, you need to create a new configuration file for your website. You can create a new file in the /etc/apache2/sites-available directory with the following command:
sudo nano /etc/apache2/sites-available/example.com.confIn this file, you need to add the following configuration:
<VirtualHost *:80>ServerAdmin webmaster@example.comServerName example.comServerAlias www.example.comDocumentRoot /var/www/example.com/public_html/ErrorLog ${APACHE_LOG_DIR}/error.logCustomLog ${APACHE_LOG_DIR}/access.log combined</VirtualHost>This configuration sets up a virtual host for example.com. You can replace example.com with your own domain name.
Save the file and exit the editor. Then, enable the virtual host by running the following command:
sudo a2ensite example.com.confFinally, reload Apache for the changes to take effect:
sudo systemctl reload apache2Setting Up Node.js
Step 1: Installing Node.js
The next step is to install Node.js on your server. You can do this by running the following command:
sudo apt-get updatesudo apt-get install nodejsStep 2: Installing NPM
Next, you need to install NPM, which is the package manager for Node.js. You can do this by running the following command:
sudo apt-get install npmSetting Up a Database
Step 1: Installing MySQL
If you are using MySQL as your database server, you can install it by running the following command:
sudo apt-get updatesudo apt-get install mysql-serverOnce the installation is complete, you need to configure MySQL by running the following command:
sudo mysql_secure_installationFollow the on-screen instructions to set up a root password and secure your installation.
Step 2: Installing MongoDB
If you are using MongoDB as your database server, you can install it by running the following command:
sudo apt-get updatesudo apt-get install mongodbOnce the installation is complete, MongoDB will start automatically. You can verify that it is running by running the following command:
sudo systemctl status mongodbConfiguring Your Application
Step 1: Creating Your Node.js Application
You can create your Node.js application by running the following command:
mkdir myappcd myappnpm initThis will create a new directory called myapp, and generate a package.json file inside it.
Step 2: Installing Dependencies
Next, you need to install the dependencies for your application. You can do this by running the following command:
npm install express body-parser mysql mongodb --saveThis will install the express, body-parser, mysql, and mongodb modules, and add them to your package.json file.
Step 3: Writing Your Backend Code
You can write your backend code in a file called app.js. Here is an example:
const express = require('express');const bodyParser = require('body-parser');const mysql = require('mysql');const mongodb = require('mongodb');// Create a new express applicationconst app = express();// Configure body-parser to handle JSON bodiesapp.use(bodyParser.json());// Set up a MySQL connectionconst mysqlConnection = mysql.createConnection({host: 'localhost',user: 'root',password: 'password',database: 'mydatabase'});// Connect to MySQLmysqlConnection.connect((err) => {if (err) {console.error('Failed to connect to MySQL', err);} else {console.log('Connected to MySQL');}});// Set up a MongoDB connectionconst mongoClient = new mongodb.MongoClient('mongodb://localhost:27017', {useNewUrlParser: true});// Connect to MongoDBmongoClient.connect((err) => {if (err) {console.error('Failed to connect to MongoDB', err);} else {console.log('Connected to MongoDB');}});// Start the serverapp.listen(80, () => {console.log('Server is listening on port 80');});This code sets up an express application, configures body-parser, and sets up connections to both MySQL and MongoDB. You can modify this code to suit your specific requirements.
Deploying Your Application
Step 1: Uploading Your Code to the Server
You need to upload your code to the server. You can do this by using an FTP client, or by using git.
Step 2: Installing PM2
PM2 is a process manager for Node.js. You can install it by running the following command:
sudo npm install pm2 -gStep 3: Starting Your Application
You can start your application by running the following command:
pm2 start app.jsThis will start your application as a background process. You can verify that it is running by running the following command:
pm2 listTroubleshooting Common Issues
Issue 1: Server Not Responding
If your server is not responding, you can check the following:
- Ensure that your server is running
- Check that your domain name is pointing to the correct IP address
- Check that your SSL certificate is valid and set up correctly
- Check your firewall settings
Issue 2: Node.js Application Crashing
If your Node.js application is crashing, you can check the following:
- Check your application logs for any error messages
- Make sure that your application is listening on the correct port
- Check that all dependencies are installed and up to date
- Check your firewall settings
