Pm2 start npm run dev

Executing ‘pm2 start npm run dev’

When you run the command pm2 start npm run dev, you are using the ‘pm2’ process manager to start the ‘npm’ command with the ‘run dev’ script. This command is typically used in Node.js projects to start a development server or run a specific script defined in the ‘package.json’ file.

Explanation and Examples

The ‘pm2’ process manager is a widely used tool in Node.js applications to manage and monitor processes. It provides several features such as process clustering, load balancing, and automatic restarts.

The ‘start’ command is used to start a new process using ‘pm2’. In this case, the process being started is ‘npm run dev’. The ‘npm’ command, which stands for Node Package Manager, is a command-line tool used to manage dependencies and scripts in Node.js projects.

The ‘npm run dev’ part refers to a script defined in the ‘package.json’ file. In the ‘scripts’ section of the ‘package.json’ file, developers can define custom commands to be executed using the ‘npm run’ command. For example, you might have a ‘dev’ script defined like this:

"scripts": {
  "dev": "node server.js"
}

In this example, running ‘npm run dev’ would execute the ‘node server.js’ command.

So, when you run ‘pm2 start npm run dev’, ‘pm2’ will start a new process that executes the ‘npm run dev’ script defined in the ‘package.json’ file. This can be useful for running development servers or any other custom scripts defined in your project.
