getting elapse time using console.time/endtime

 

By running console.time("your-time-label") and then console.endTime("your-time-label"), you automatically get elapse time of your process.

import request from 'request';

import process from 'node:process';

function exec(i: number): Promise<void>  {

  return new Promise((resolve, reject) => {  

    request.get('http://www.google.com', (err: any, resp: any) => {

      if(err) {

        reject('error');

        return console.error(err);

      }

      console.log("Total bytes received: ", resp.body.length, process.pid, i);  

      resolve(resp.body.length);

      });

  })

}

console.time("test");

const promises = [];

for (let i = 0; i < 5; ++i) {

    promises.push(exec(i));

}

Promise.all(promises)

.then((results) => {

    console.log("All done", results);

    console.timeEnd("test");

})

.catch((e) => {

    // Handle errors here

});

Outputs - shown here - so much easier than process.hrtime as you need to do some calculation too - As seen here.
