Install NodeJS and NPM

There are some methods to install both NodeJS and NPM. In this article, we will install them using the node source. For other methods, you can check our blog post on how to install NodeJS and NPM.

<syntaxhighlight lang="bash"> curl -sL https://deb.nodesource.com/setup_14.x | sudo -E bash - </syntaxhighlight>

Once completed, we need to download the package information from the newly added source above.

<syntaxhighlight lang="bash"> sudo apt update </syntaxhighlight>

Next, run the following command to finally install NodeJS and NPM.

<syntaxhighlight lang="bash"> sudo apt install nodejs </syntaxhighlight>

NodeJS and NPM have been successfully installed, you can check the installed version using this command:

Install Gatsby-CLI

Gatsby CLI is the main entry point for getting up and running the Gatsby application. It is packaged as an executable that can be used globally. We can install Gatsby CLI via npm.

<syntaxhighlight lang="bash"> sudo npm install -g gatsby-cli </syntaxhighlight>

To check the installed version of Gatsby CLI, run this command:

<syntaxhighlight lang="bash"> gatsby --version </syntaxhighlight>

Now, let’s create a new Gatsby website, you can replace “gatsby_site” with any name you like.

<syntaxhighlight lang="bash"> gatsby new gatsby_site </syntaxhighlight>

Wait for a few moments, and a new “gatsby_site” directory is created.

Invoke the command below to develop Gatsby and run it.

<syntaxhighlight lang="bash"> cd gatsby_site </syntaxhighlight>

<syntaxhighlight lang="bash"> gatsby develop -H 0.0.0.0 </syntaxhighlight>

You should be able to access your Gatsby site at http://YOUR_SERVER_IP_ADDRESS:8000, press CTRL + C if you want to stop it.

Now, let’s build our Gatsby website:

<syntaxhighlight lang="bash"> gatsby build </syntaxhighlight>

The gatsby build command is a part of the Gatsby CLI. Run gatsby build command to create a production-ready version of your site when you are ready to publish your site. You can also deploy your Gatsby website to GitHub to set up a CI/CD (Continuous Integration and Continuous Deployment) pipeline.

Install PM2

Process Manager (PM2) will allow you to keep applications alive forever, reload them without downtime, and facilitate common system admin tasks. Invoke the command below to install PM2 on your Ubuntu 20.04 globally.

<syntaxhighlight lang="bash"> sudo npm install pm2 -g </syntaxhighlight>

After installing PM2, we can run these commands to start our Gatsby website on port 8000.

<syntaxhighlight lang="bash"> cd ~/gatsby-site </syntaxhighlight>

<syntaxhighlight lang="bash"> pm2 start gatsby --name mygatsby -- serve -p 8000 </syntaxhighlight>

Install and Configure NGINX

Your Gatsby install has now been completed and you should be able to access it at your server’s public IP with port number 8000. However, if you want to access your Gatsby website using a domain name or subdomain name instead of typing the server’s IP address and the port number in the URL, you would need to configure a reverse proxy on your server.

In this step, we will show you how to implement the reverse proxy configuration using Nginx. Nginx is a powerful and high-performance web server that focuses on customization and performance.

First, install Nginx with the following command:

<syntaxhighlight lang="bash"> sudo apt install nginx </syntaxhighlight>

On Ubuntu 20.04, Nginx is configured to start running upon installation, you can check it by running this command:

<syntaxhighlight lang="bash"> sudo systemctl status nginx </syntaxhighlight>

Once installed, create a new Nginx server block configuration file. Replace yourdomain.com with your actual domain or subdomain name

<syntaxhighlight lang="bash"> sudo nano /etc/nginx/sites-enabled/yourdomain.com.conf </syntaxhighlight>

Add the following content to the file:

server {

    listen 80;

   server_name yourdomain.com;
   location / {
       proxy_pass http://localhost:8000;
       proxy_http_version 1.1;
       proxy_set_header X-Forwarded-Host $host;
       proxy_set_header X-Forwarded-Server $host;
       proxy_set_header X-Real-IP $remote_addr;
       proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
       proxy_set_header X-Forwarded-Proto $scheme;
       proxy_set_header Host $http_host;
       proxy_set_header Upgrade $http_upgrade;
       proxy_set_header Connection "Upgrade";
       proxy_pass_request_headers on;
   }
   location ~ /.well-known {
      allow all;
   }

} </syntaxhighlight>

Save the file by pressing CTRL + O then press CTRL + X to exit the nano editor then restart Nginx.

<syntaxhighlight lang="bash"> sudo systemctl restart nginx </syntaxhighlight>
