Specifically, I use Amazon Lightsail and pm2.

Creating an Amazon Lightsail Instance

Select the Node.js blueprint.

Also, since port 3000 is used, open the firewall for it.

pm2 Configuration

I referred to the following article.

Installation

sudo su
npm install pm2 -g

Downloading and Building Nuxt 3

Download the sample program.

su bitnami
cd /home/bitnami/
git clone https://github.com/nakamura196/nuxt3-pm2

Setup

cd nuxt3-pm2
npm install

Build

npm run build
npm run preview

You can verify the Nuxt 3 application at localhost:3000.

Starting with pm2

cd /home/bitnami/
vi /home/bitnami/ecosystem.config.js

module.exports = {
  apps: [{
    name: 'demo',
    cwd: '/home/bitnami/nuxt3-pm2',
    exec_mode: 'cluster',
    instances: 'max',
    script: './.output/server/index.mjs',
    watch: ['./'], // or true
    watch_options: {
      followSymlinks: true,
      usePolling: true,
      interval: 10000,
      binaryInterval: 10000,
    },
    env: {
      PORT: 3000,
      NODE_ENV: 'production',
    }
  }]
}

Start pm2 with the following command.

pm2 start /home/bitnami/ecosystem.config.js

Daemonization

As a future TODO, as mentioned in the following article, placing pm2 under systemctl management is one consideration.

I would like to try this on another occasion.

Summary

I was able to deploy a Nuxt 3 application using pm2 on a VPS (Amazon Lightsail) environment. We hope this is helpful for deploying Nuxt 3 applications in non-serverless environments.
