Step 3: Start Your Node.js Application with PM2

To start your Node.js application with PM2, navigate to the directory where your application is located and run:

This will start your application in the background and allow it to run continuously. PM2 will automatically restart your application if it crashes or if the server is restarted.

Step 4: Manage Your Node.js Application with PM2

You can manage your Node.js application with PM2 by using various commands. Some of the most commonly used commands include:

  • pm2 list: Shows a list of all running Node.js applications.
