Examples

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 parameter 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);

Web with module

elapsed.start('testoverride');
setTimeout(()=>{

}, 100);

elapsed.start('vlad');
setTimeout(()=>{
    const test = elapsed.get('vlad');
    console.log(test);
}, 1200);

// ElapsedLogger is similliar to console.time() & console.timeEnd() 
elapsed.start('label');
elapsed.start('timer label');
setTimeout(()=>{
    elapsed.end('label');
    elapsed.end('timer label');
}, 800);

// or use ElapsedLogger as an instance (recommended)
