Debug Timer: benchmark the performance of multiple parts of your code

Measure the duration of multiple parts of your code, then effortlessly print all the timer results at once to the console.

What you get

Sample output:

Loading file: 506 ms
Processing data: 858 ms

How to get it

You will use three methods: timer.start('task name'), timer.end('task name'), and timer.print() to show the results in the console. The print() method also returns the results as string, so you can save it to some logs if you need.

const DebugTimer = require('debugging-timer');
let timer = new DebugTimer();

(async () => {
	timer.start('Loading file');
	// Let's pretend we are doing some work here:
	await delay(500);
	timer.end('Loading file');	

	timer.start('Processing data');
	await delay(850);
	timer.end('Processing data');
	
	// Let's see the results!
	timer.print();

	// Prints:
	// Loading file: 506 ms
	// Processing data: 858 ms
})();

async function delay(ms) {
	await new Promise(resolve => setTimeout(resolve, ms));
}
