Launch an EC2 instance and install Node.js, Nginx, and PM2:

sudo apt-get update
sudo apt-get install -y nodejs npm nginx
sudo npm install -g pm2

Clone your app from your Git repository onto the EC2 instance

git clone repo

Install NVM :

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash

Source Bashrc :

source ~/.bashrc 

Install node version required :

nvm install 16

Install the required dependencies using npm install.

cd your-sveltekit-app
yarn

Build your app using npm run build.

yarn build

Start your app using PM2 by running pm2 start npm --name "app-name" -- start.

pm2 start npm --name "app-name" -- start

Configure Nginx as a reverse proxy to forward requests to your app.

sudo nano /etc/nginx/conf.d/your-domain-name.conf

Paste the following content into the file, replacing your-domain-name.com with your actual domain name or your EC2 instance's public IP address:

server {
  listen 80;
  server_name your-domain-name.com;
  location / {
    proxy_pass http://localhost:3000;
    proxy_set_header Host $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;
  }
}

Restart Nginx to apply the configuration changes:

sudo service nginx restart

To install Certbot on Ubuntu, you can run the following commands:

sudo apt update
sudo apt install certbot

Run Certbot with the certonly command to obtain the SSL certificate. For example, to obtain a certificate for the domain xyz.com, you would run:

sudo certbot certonly --webroot -w /var/www/html -d xyz.com

Update Nginx config :

server {
    listen 443 ssl;
    server_name xyz.com;

    ssl_certificate /etc/letsencrypt/live/adsv2.com/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/adsv2.com/privkey.pem;

    location / {
        proxy_pass http://localhost:3000;
        proxy_set_header Host $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;
    }
}

Restart Nginx to apply the configuration changes:

sudo service nginx restart
