akuku

Small timing counter utility. Uses process.hrtime to collect all time intervals between start and stop.

Install

$ npm install --save akuku

Usage

let tm = require('akuku')('module name'); // kind of like debug

let countSomething = tm.counter('something');

tm.start();
// do something

countSomething();

tm.stop();

next = tm.start(next);

doSomethingAsync(function() {

  countSomething(5); // you can optionally pass a bigger counter

  next();
});

// later

tm.dump(); // will print sum of times between start and stop, and all associated counters

API

start(next = undefined, count = 1)

Starts counting time - returns the stop function. If next is specified returns wrapped version of next that stops timer before calling next.

stop()

Stops counting time.

toString()

Displays formatted internal state - something like:

toObject()

Raw state:

• active - sum of all intervals between start and stop as [ seconds, nano ] pair
• counter - number of times start was called
• activeNow - true if between start and stop when called
• counters - additional counters as name => values object

counter(name)

Creates additional named counter. Returns counter function, which - whenever called - will increment internal counter named name Its value will become part of the state.
