How to Deploy a React application with NGINX (Step-by-Step Guide) ๐Ÿš€

Prerequisites:

  • A basic React project to deploy.

  • A Linux machine or server.

  • Domain name (optional).

So, you've mastered web development and created a fantastic webapp using react, Now, you're eager to share it with the world. But how do you deploy it on the internet? Fear not; I'm here to guide you through the process.

To get started, you'll need a Linux machine or VM. (how to create one?)

Step 0 - Connect to your VM (if using cloud)

connect to your virtual machine using any of the following ways so we can start installing and configuring NGINX server on it.
A. Connect using ssh-

ssh ashutosh@192.168.1.7 โ†ฉ๏ธ
fingerprint(yes) โ†ฉ๏ธ
yourpassword โ†ฉ๏ธ

this will start a shell session like-

ashutosh@yourvm:~$

B. You can use VNC / RDP, for more info google vnc with your cloud provider term.

You can skip above step if you are setting up NGINX on a local server.

Step 1 - Update Your Packages ๐Ÿ”„

First things first, ensure your system is up-to-date by running this command:

sudo apt update && sudo apt upgrade

๐Ÿ’กPro tip: If you're feeling lazy, you can use sudo su to avoid typing sudo twice!

Step 2 - Install NGINX Server ๐ŸŒ

Let's get NGINX on board. Run this command:

sudo apt install nginx

Now, technically, NGINX should be installed and running. To test this, let's execute the following command:

curl localhost

This should give the following output:

bloguser@blogvm:~$ curl localhost

<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style></style>
</head>
<body>
<h1>Welcome to nginx!</h1>
<p>If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.</p>
<p><em>Thank you for using nginx.</em></p>
</body>
</html>

If you are getting this output, it means NGINX is installed and up and running.

Step 3 - Enable and Configure firewall๐Ÿ”ฅ๐Ÿงฑ

Currently NGINX is running locally, if you try to open the VM's ip in browser it will not show anything, which is obvious as have not enabled http (80) and https(443) ports from firewall.

sudo ufw enable
sudo ufw status
sudo ufw allow 'Nginx Full'
sudo ufw status

Step 4 - Install NodeJs๐Ÿš‚

Execute following command:

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.1/install.sh | bash

Reload the configuration

source ~/.bashrc

test the installation with nvm -v you should see version number.

finally install NodeJs with nvm install 21.0.0

Step 5 - Verify Your Setup โœ…

After this, your webpage should show up, it's time to see if everything's working. You can do this by typing your server's Public IP address in your web browser.

Step 6 - Creating a simple Website ๐ŸŒŸ

By default, NGINX comes with a basic site enabled. You can customize its content, which is located at /var/www/html.

Lets modify default page with our content.

Step 1 - Navigate to default directory

cd /var/www/html/
ls
sudo rm -r index.html index.nginx-debian.html 
ls
sudo nano index.html
    //if you don't have nano
vim index.html -> i

paste this sample html file-

<!DOCTYPE html>
<html>
<head>
    <style>
        body {
            background-color: #f0f0f0;
            font-family: Arial, sans-serif;
            display: flex;
            justify-content: center;
            align-items: center;
            height: 100vh;
            margin: 0;
        }
        h1 {
            color: #333;
        }
    </style>
</head>
<body>
    <h1>Hello, World!</h1>
</body>
</html>

save and exit

nano -> ctrl+x -> y -> enter.

vim -> :wq -> enter.

Restart the NGINX server

nginx -t                        //to check the configuratin
sudo systemctl restart nginx    //to restart nginx

Then refresh you webpage, it will look something like this-

So this is how you setup a simple static web server with NGINXโœจ

How to host your React web app here?

Now, letโ€™s deploy your React application using NGINX. Follow these steps:

Step 7 - Clone Your React Project to NGINX Root Directory ๐Ÿ“‚

First, clone your React project into the NGINX root directory.
You can choose /var/www/ or any other directory.

cd /var/www/
sudo git clone https://github.com/yourusername/your-react-project.git
cd your-react-project

Step 8 - Install Dependencies and Build the Project ๐Ÿ“ฆ

Navigate to your project directory, install dependencies, and build your React application.

cd /var/www/your-react-project
npm install
npm run build

The build command will create a build directory with your optimized React application.

Step 9 - Configure NGINX to Serve Your React Application โš™๏ธ

Next, configure NGINX to serve your React application. Edit the NGINX configuration file:

sudo nano /etc/nginx/sites-available/default

Replace the contents with the following configuration:

server {
    ...

    root /var/www/your-react-project/build;
    index index.html index.htm;

    ...
}

Save and close the file

Step 10 - Restart NGINX Server ๐Ÿ”„

Finally, restart the NGINX server to apply the changes:

sudo nginx -t        # To check the configuration
sudo systemctl restart nginx

Step 11 - Access Your React Application ๐Ÿฅณ

Your React application should now be live. Open your browser and navigate to your serverโ€™s public IP or domain name:

http://yourdomain.com

You should see your React app running! ๐ŸŽ‰

That's it! You've successfully deployed your React application with NGINX. For adding a domain name, stay tuned for our next blog post.
