Analysis.js
A simply javascript library for using performance api in both Node.js and web easier
Install
$ npm i analysis.js --save
Usage
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.
