Alright, let's get started! First things first, we need Node.js. I'm going to assume you already have it installed. If not, no worries—just grab it from the official Node.js website.

Next up, we need PM2. It's a handy process manager for Node.js apps. Think of it as your app's personal assistant, handling restarts, logs, clustering, and more.

To install PM2, just pop open your terminal and run:

npm install -g pm2

Now, let's get Supabase. It's an open-source alternative to Firebase, offering a full-stack backend with native support for React, Vue, and Angular.

To install it, run:

npm install -g create-supabase

With Supabase installed, it's time to create a new app. Let's call it "my-supabase-app".

npx create-supabase my-supabase-app

This command will set up a new Supabase app in a directory named "my-supabase-app".

Now that your Supabase app is ready, let's configure it with PM2 for process management.

First, create a file named "ecosystem.config.js" in the root of your project. This file will define your app for PM2.

cd my-supabase-app
touch ecosystem.config.js

Open "ecosystem.config.js" in your favorite text editor and paste this:

module.exports = {
  apps : [{
    name: 'My Supabase App',
    script: 'npm',
    args: 'start',
    autorestart: true,
    watch: false,
    max_memory_restart: '1G',
    env: {
      NODE_ENV: 'development'
    },
    env_production: {
      NODE_ENV: 'production'
    }
  }],
};

This tells PM2 to start your Supabase app with "npm start" and restart it if it crashes.

Now, let's fire up your Supabase app using PM2:

pm2 start ecosystem.config.js

This command will start your app and keep it running in the background.

When you're ready to deploy to production, remember to use the "--env production" option:

pm2 start ecosystem.config.js --env production

With PM2 managing your app, you can list the currently running applications with:

pm2 list

To stop your app, use:

pm2 stop 'My Supabase App'

And to restart it, just run:

pm2 restart 'My Supabase App'

PM2 offers a bunch of other features like log management, monitoring, and clustering. You can dive deeper into these in the official PM2 documentation.
