Usage

1. npm install nodejs-performance-profiler
const PerformanceProfiler = require("nodejs-performance-profiler");
        
// Initialize the profiler
const profiler = new PerformanceProfiler();
        
// Perform operations to profile
const memoryUsage = profiler.getMemoryUsage();
const cpuUsage = profiler.getCpuUsage();
const upTime = profiler.getUpTime();
        
// console results
console.log(memoryUsage, cpuUsage, upTime);
        
// Log profiling results to a file
profiler.logResults("performance.txt");
The provided code exemplifies the utilization of the Node.js Performance Profiler library to analyze the performance of Node.js applications. After initializing the profiler, it captures memory usage, CPU usage, and uptime metrics. These metrics are then displayed in the console for real-time insights. Additionally, the profiler logs the gathered results to a designated file, facilitating comprehensive performance evaluation and optimization strategies.
