StopWatch

simple class utility for tracking amount of time elapsed in milliseconds (ms).

version 1.1.0: added typescript type definitions for StopWatch class version 1.3.0: fixed bug where when initially calling .stopTimer() before subsequent calls to .startTimer() when the StopWatch object is first instantiated, it will cause the incorrect time elapsed to be returned

how to use StopWatch class via NPM/node.js

installation from terminal/CMD line

npm i @slime/stopwatch

usage: first instantiate a new StopWatch object instance from the StopWatch class

const StopWatch = require("@slime/stopwatch");
let stopWatch = new StopWatch();

API to start, stop, resume, reset with:

stopWatch.startTimer();
stopWatch.stopTimer();
stopWatch.startTimer();
stopWatch.reset();

getters API to query number of ms elapsed and display time elapsed as minutes/seconds/ms string:

stopWatch.getTimeElapsedInMs; // returns number of time elapsed in ms
stopWatch.getTimeElapsedInStopWatchFormatString; // returns mins/secs/ms in 00:00:00 format

demo usage

start timer and show time elapsed after 1.5 seconds

const StopWatch = require("@slime/stopwatch");
let stopWatch = new StopWatch();
console.log(stopWatch.getTimeElapsedInMs);
console.log(stopWatch.getTimeElapsedInStopWatchFormatString);
stopWatch.startTimer();
setTimeout(()=>{
    stopWatch.stopTimer();
    console.log(stopWatch.getTimeElapsedInMs);
    console.log(stopWatch.getTimeElapsedInStopWatchFormatString);
}, 1500);
