Create a production server for a NodeJs wep app

  • by

I have created a NodeJs wep app, which I wanted to host on a unmanaged server. This guide shows how I have done it on an ubuntu 18.10 lts server.

Environment variables for NodeJs

If the web app is on a production server, it should know that. Otherwise some installed npm packeges log extensively.

vi ~/.bashrc
...
# NODEJS ENVIRONMENT VARIABLES AT THE END OF THE FILE
export NODE_ENV=production
export PORT=8080

Handle the NodeJs app with pm2

Install pm2 globally:

sudo npm install pm2 -g

Start the NodeJs:

pm2 start app.js --name "My Web App"

Show an overview:

pm2 list

Make the app available by with nginx

Install nginx

sudo apt-get install nginx

Configure

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

default file content

server {
    listen 80;

    server_name my-node-app.ch;

    location / {
        proxy_pass http://127.0.0.1:8080;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
    }
}

Activate the app

sudo servive nginx restart

And now the wep app should be reachable.
