How to Install ReactJS with Nginx on Ubuntu 22.04

React.js is a free and open-source JavaScript framework developed by Facebook in 2011. It is used for building reusable UI components and helps users to create rich and engaging web apps fast and efficiently with minimal coding. With React, you can build an interactive web interface and compose complex UIs from small and isolated pieces. It uses Virtual DOM which makes the app fast. It provides a lot of features such as Virtual DOM, One-way Data Binding, Components, JSX, Conditional Statements, and many more.

In this tutorial, we will show you how to install React.js on Ubuntu 22.04.

Prerequisites

  • A server running Ubuntu 22.04.
  • Valid domain name pointed with your server IP.
  • A root password is configured on the server.

Getting Started

First, you will need to update your system packages to the latest version. You can update them using the following command:

apt-get update -y
apt-get upgrade -y

Once all the packages are up-to-date, run the following command to install other required dependencies:

apt-get install curl gnupg2 -y

Once all the dependencies are installed, you can proceed to the next step.

Install Node.js

Next, you will need to install Node.js on your server. By default, the latest version of Node.js is not available in the Ubuntu 22.04 standard repository. So you will need to install Node.js from the Node.js official repository.

First, add the Node.js repository with the following command:

curl -sL https://deb.nodesource.com/setup_18.x | bash -

Next, run the following command to install the Node.js to your system:

apt-get install nodejs -y

After installing Node.js, update the NPM to the latest version using the following command:

npm install [email protected] -g

You should get the following output:

removed 14 packages, changed 73 packages, and audited 223 packages in 3s

14 packages are looking for funding
  run `npm fund` for details

found 0 vulnerabilities

Next, verify the installed version of Node.js with the following command:

node -v

You should get the following output:

v18.12.1

Once you are finished, you can proceed to the next step.

Install Create React App Tool

Create React App is a CLI tool that helps users to save time for setup and configuration. You just need to run a single command and Create React App will set up all tools need to start your project.

You can install the Create React App tool using the following command:

npm install -g create-react-app

Once you are finished, you can proceed to the next step.

Create a Sample React Application

In this section, we will create a sample React app with Create React App tool.

First, change the directory to /opt and create your first project with the following command:

cd /opt
create-react-app reactapp

You should see the following output:

Success! Created reactapp at /opt/reactapp
Inside that directory, you can run several commands:

  npm start
    Starts the development server.

  npm run build
    Bundles the app into static files for production.

  npm test
    Starts the test runner.

  npm run eject
    Removes this tool and copies build dependencies, configuration files
    and scripts into the app directory. If you do this, you can’t go back!

We suggest that you begin by typing:

  cd reactapp
  npm start

Happy hacking!

Next, change the directory to your project directory and start your application with the following command:

cd /opt/reactapp
npm start

You should get the following output:

Compiled successfully!

You can now view reactapp in the browser.

  http://localhost:3000

Note that the development build is not optimized.
To create a production build, use npm run build.

webpack compiled successfully

Press CTRL+C to stop the application. We will create a systemd service file to manage the React application.

Create a Systemd Service for React App

Next, you will need to create a systemd service for your React app. You can create it with the following command:

nano /lib/systemd/system/react.service

Add the following lines:

[Service]
Type=simple
User=root
Restart=on-failure
WorkingDirectory=/opt/reactapp
ExecStart=npm start -- --port=3000

Save and close the file then reload the systemd daemon with the following command:

systemctl daemon-reload

Next, start the React service and enable it to start at system reboot by running the following command:

systemctl start react
systemctl enable react

You can verify the status of the React service with the following command:

systemctl status react

You should get the following output:

? react.service

Nov 20 11:18:55 ubuntu2204 npm[76148]: webpack compiled successfully

Once you are finished, you can proceed to the next step.

Configure Nginx as a Reverse Proxy

It is a good idea to install and configure Nginx as a reverse proxy for React App. So you can access your app through port 80.

First, install the Nginx package using the following command:

apt-get install nginx -y

Once the Nginx is installed, create a new Nginx virtual host configuration file:

nano /etc/nginx/sites-available/reactjs.conf

Add the following lines:

upstream backend {
  server localhost:3000;
}

server {
    listen 80;
    server_name reactjs.example.com;

    location / {
        proxy_pass http://backend/;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
        proxy_set_header Host $http_host;

        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forward-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forward-Proto http;
        proxy_set_header X-Nginx-Proxy true;

        proxy_redirect off;
    }
}

Save and close the file then enable the Nginx virtual host with the following command:

ln -s /etc/nginx/sites-available/reactjs.conf /etc/nginx/sites-enabled/

Next, verify the Nginx for any syntax error by running the following command:

nginx -t

You should get the following output:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Finally, restart the Nginx service to apply the changes:

systemctl restart nginx

You can also verify the Nginx service status with the following command:

systemctl status nginx

You should see the following output:

? nginx.service - A high performance web server and a reverse proxy server
     Loaded: loaded (/lib/systemd/system/nginx.service; enabled; vendor preset: enabled)

At this point, Nginx is installed and configured to serve React App. You can now proceed to the next step.

Secure React.js with Let's Encrypt

Next, you will need to install the Certbot client package to install and manage the Let's Encrypt SSL.

First, install the Certbot with the following command:

apt-get install python3-certbot-nginx -y

Once the installation is finished, run the following command to install the Let's Encrypt SSL on your website:

certbot --nginx -d reactjs.example.com
