Introduction of forever alternative tool pm2

[Goodbye node-forever, hello PM2][pm2] [pm2]: (http://devo.ps/blog/2013/06/26/goodbye-node-forever-hello-pm2.html)

After reading the introduction of the tool, I think it is quite convenient, but it is a bit crazy that it does not support CoffeeScript:

Github: https://github.com/Unitech/pm2

npm install -g pm2

Features

PM2 thinks that Forever has some disadvantages:

• Limited functionality for logging and monitoring
• Limited process and cluster management
• Aging codebase (Upgrading Node can easily lead to application failure)

Visually, it's easier to use than Forever... PM2 was just written a few months ago, and it's not perfect: The plans listed are:

• Remote administration/status checking,
• Built-in inter-processes communication channel (message bus),
• V8 GC memory leak detection,
• web interface,
• Persistent storage for monitoring data,
• E-mail notification

Then try the local installation:
