Performetrics - Express Performance Monitoring Package

Performetrics is an easy-to-use npm package for monitoring the performance of ExpressJS applications in real-time. It collects metrics such as response times, CPU and memory usage, and provides visualizations and suggestions for optimizing your applications.

Installation

Install the Performetrics package via npm:

npm install performetrics

Usage

1. Import the Performetrics package and initialize it in your ExpressJS application:

const express = require('express');
const {monitor} = require('performetrics');

const app = express();

// Initialize Performetrics middleware
app.use(monitor());

// Other middleware and route handlers
app.listen(3000, () => {
    console.log('Server is running on port 3000');
});

2. Start your ExpressJS application, and the Performetrics middleware will automatically log performance metrics for incoming requests.
