Which one is better: Node.js built in cluster or PM2 clustering?

When deciding between Node.js built-in clustering and PM2 clustering, the choice largely depends on the specific requirements and context of your application. Both methods offer distinct advantages and are suited to different scenarios.

Node.js Built-in Cluster Module

The Node.js built-in cluster module allows you to increase the performance of Node.js applications by enabling the creation of child processes that run simultaneously and share the same server port. This module is part of the Node.js runtime, which means it doesn't require any additional dependencies.

Advantages:

• Direct Control: It provides more control over how child processes are managed, spawned, and how they communicate[1][7].
• Customization: Since it is a lower-level API, it allows for more customized implementations tailored to specific needs[1][7].
• No External Dependencies: Using the built-in cluster module does not require installing any third-party packages, which can simplify deployment and reduce potential for conflicts[7].

Disadvantages:

• Complexity: It requires more boilerplate code and manual setup compared to PM2, which might increase the complexity of your application[1][7].
• Limited Built-in Features: Unlike PM2, the built-in cluster module does not provide built-in features for process monitoring, logging, or automatic restarts[1][7].

PM2 Clustering

PM2 is a process manager for Node.js applications that offers built-in support for clustering. It is designed to improve the manageability and reliability of applications by providing features like process monitoring, logging, and automatic restarts.

Advantages:

• Ease of Use: PM2 simplifies the process of managing clustered applications with minimal code changes. It can automatically handle the creation and management of worker processes[1][2][3].
• Additional Features: PM2 provides built-in tools for monitoring and logging, as well as t...
