In the realm of Node.js application deployment, efficiency, reliability, and ease of management are paramount. One tool that stands out in this regard is PM2 (Process Manager 2). Let's explore the why and how of deploying Node.js applications using PM2, unlocking a world of streamlined processes and robust performance.
Understanding PM2:
PM2 is a process manager for Node.js applications that simplifies the deployment and management of Node processes in production environments. It comes with a powerful set of features, making it a popular choice for developers and system administrators.
Why Choose PM2 for Deployment?
##Process Management:PM2 excels in managing Node.js processes, ensuring they run continuously, automatically restarting in case of failure, and providing a straightforward way to stop or restart applications.
Zero Downtime Deployment:PM2 supports zero-downtime deployments, meaning you can update your application without interrupting the live service. New versions are started in parallel with the old ones, and the traffic is switched seamlessly.
Load Balancing:For applications with multiple instances, PM2 offers built-in load balancing, distributing incoming requests evenly across instances, optimizing resource utilization, and enhancing overall performance.
Logging and Monitoring:PM2 provides robust logging capabilities, allowing you to monitor application logs in real-time. Additionally, it comes with a built-in dashboard for monitoring CPU usage, memory consumption, and other metrics.
Ecosystem File:PM2 uses an ecosystem file (usually ecosystem.config.js) to manage the configuration of your applications. This allows you to define multiple applications, set environment variables, and configure other options.
