Deploying an express.js package

Question

I am creating a web application using express.js. I have been following a course by Angela Wu, and one of the chapters involves a templating tool called 'Express' which is built on node.js. Following is a very simple example for a file named 'node.js':

import express from "express"; const app = express(); const port = 3000; app.get("/", (req, res) => { res.send("<h1>Hello World!</h1>"); }); app.listen(port, () => { console.log(`Listening on port $(port)`) });

To run this, I open a terminal window inside of Visual Studio Code, and execute the command

node index.js

This will then use the 'node' library to create an http listener on 'localhost/3000'.

Now here is the question: How can I deploy this simple application to a remote host?

you can use various approach. This is the most common production setup.

Step 1: SSH into your server

ssh user@your_server_ip

Step 2: Install Node & Git

sudo apt update sudo apt install -y nodejs npm git

Step 3: Clone your project

git clone https://github.com/your/repo.git cd repo npm install

Step 4: Install PM2 (process manager)

PM2 keeps your Node app running in the background:

sudo npm install -g pm2 pm2 start server.js --name myapp pm2 save pm2 startup

Step 5: Configure Nginx as reverse proxy

Install Nginx: sudo apt install nginx Create a config file: sudo nano /etc/nginx/sites-available/myapp Add: server { listen 80; server_name your_domain_or_ip; location / { proxy_pass http://localhost:3000; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; } } Enable the site: sudo ln -s /etc/nginx/sites-available/myapp /etc/nginx/sites-enabled/ sudo systemctl restart nginx
