PM2 is a production process manager for Node.js applications with a built-in load balancer. It allows you to keep applications alive forever and reloads them without downtime.
Here is a basic example of how to use PM2:
# Install PM2
npm install pm2 -g
# Start your application
pm2 start app.js
# To ensure PM2 starts when your system boots, use:
pm2 startup
PM2 can also monitor your applications and provide useful information about their status, CPU, and memory usage.
