Package Exports

elapsed-time-logger

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (elapsed-time-logger) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Usage

NodeJS

const elapsed = require("elapsed-time-logger");
// chalk is't required, added as example to show that you can use colors in output
const chalk = require('chalk');
 
// elapsed is similliar to console.time() & console.timeEnd() 
elapsed.start('label');
elapsed.start('label_id');
setTimeout(()=>{
    elapsed.end('label');//output: label 801ms
    elapsed.end('label_id', 'Text that goes here will override label on output');
    // output: Text that goes here will override label on output 801ms
}, 800);
// if paramter label is not provided, start() will return an instance 
const elapsedTimer = elapsed.start();
const elapsedTimer2 = elapsed.start();
setTimeout(()=>{
    elapsedTimer2.end(chalk.green('you can use colors here, try chalk or colors packages:'));
    // output: you can use colors here, try chalk or colors packages: 806ms
    const time = elapsedTimer.get();//return 806ms
    console.log(time);
    elapsedTimer.end('finished:');// output: finished: 806ms
}, 800);

ESM (Browser e.g Angular, react, etc.)

import elapsed from 'elapsed-time-logger';
// elapsed is similliar to console.time() & console.timeEnd() 
elapsed.start('label');
elapsed.start('label_id');
setTimeout(()=>{
    elapsed.end('label');//output: label 801ms
    elapsed.end('label_id', 'Text that goes here will override label on output');
    // output: Text that goes here will override label on output 801ms
}, 800);
// if paramter label is not provided, start() will return an instance 
const elapsedTimer = elapsed.start();
const elapsedTimer2 = elapsed.start();
setTimeout(()=>{
    elapsedTimer2.end('elapsed2:');
    // output: you can use colors here, try chalk or colors packages: 806ms
    const time = elapsedTimer.get();//return 806ms
    console.log(time);
    elapsedTimer.end('finished:');// output: finished: 806ms
}, 800);
