Forever
Forever is a simple command-line tool for ensuring that a Node.js application runs continuously (i.e., forever) in the background, automatically restarting it if it crashes or stops. It provides basic process management features like starting, stopping, and listing running applications, making it useful for keeping web servers or scripts alive without manual intervention.
Developers should use Forever when they need a lightweight, no-frills solution to keep Node.js applications running in production or development environments, especially for simple projects where more complex process managers like PM2 might be overkill. It's ideal for small-scale deployments, background tasks, or quick prototyping where automatic restarts are necessary to maintain uptime.
