service-systemd

Purpose

Setup a node.js app as systemd service.

Sometimes you just want an "old style" daemon for simple services.
Sometimes you have to deploy in small devices (like a RaspberryPi) and you can't use Docker and all the band.

Installing

npm i -g service-systemd

Quick start

• Install service

  • pass settings in command line (see full documentation for all options)

  sudo service-systemd --add --service my-service --cwd /path/to/service --app main.js

  • pass all settings in JSON file

  sudo service-systemd --add --settings service.json

• Run the service

sudo service my-service start
sudo service my-service stop
sudo service my-service restart

• Uninstall service

sudo service-systemd --remove --service my-service

Programmatic usage

const service = require('service-systemd')

// add service

try {
  await service.add({
    name: 'my-service',
    cwd: '/path/to/app',
    app: 'main.js',
    env: {
      NODE_ENV: 'prod',
      PORT: 3002
    }
  })
  console.log('my-service installed')
} catch (error) {
  console.error('something wrong', error)
}

// remove service

try {
  await service.remove('my-service')
  console.log('my-service removed')
} catch (error) {
  console.error('something wrong', error)
}

Engines

App can run using engines: node (default), forever, pm2. With forever and pm2 you can use their options and tools.
