As a full-stack JavaScript Developer, NodeJs and Express are the most important technologies to use. Sometimes, these technologies use more and more MB from RAM and Cores from the CPU.

The important here is, how to monitor your NodeJs processes and usage. A few weeks ago a repository called Express Status Monitor was published on GitHub which helps to monitor everything.

I have installed it on my project and it turns out quite useful.

Why should I use this library?

As a JavaScript developer, you are responsible for managing your server. This simple library can help you monitor them and whenever there is an error or overload on the server, you can manage it.

How should I use this javascript library in my project?

For using this project, simply add the library and define the route in the express js.

Run npm install express-status-monitor --save

Before any other middleware or router add following line:

app.use(require('express-status-monitor')());

Run server and go to /status

When should I change my code for getting better performance?

Personally speaking, whenever your website becomes slow, something is wrong with your server. However, sometimes it is the server fault for weak processors.
