Analysis.js

A simply javascript library for using performance api in both Node.js and web easier

Install

$ npm i analysis.js --save

Usage

``javascript
import { Analysis } from 'analysis.js';
...
const performance = Analysis.getPerformance();
performance.now();

const performanceObserver = Analysis.getPerformanceObserver();
const perf_observer = (list, observer) => {
// Process the "measure" event
};
const observer2 = new performanceObserver(perf_observer);
observer2.observe({entryTypes: ["measure"]});
`

Analysis.getPerformance() in web context will return window.performance, and in Node.js context will return perf_hooks.performance.
So performance.getEntries() will not work in Node.js context, you will need to use PerformanceObserver` to get the list.
