Run Node app on your local machine, in the background

In my last post I wrote how to run a Telegram bot on Fly.io. This is cool and all, but sometimes you don't need your Node.js app to run 24/7. Instead, running it only when your laptop/desktop is on might be enough for many cases.

Running Node apps using pm2 is super easy; it's lightweight, runs smoothly in the background and requires almost no setup at all:

  1. Install pm2: npm install pm2 -g
  2. Start your Node app with pm2: pm2 start index.js --name my-app
  3. Generate a startup script: pm2 startup
  4. Save the app list to be restored at reboot: pm2 save
