Event Tracker

The library supports 3 operations:

1. sendEvent() - signal that a single event happened. The event will 'live' for 5 minutes. It is possible to override the 5 minutes and pass an integer argument in milliseconds, but is not necessary and this featuer is mainly used for testing.

2. getEventsAtTime(seconds) - request the number of events that happened over a user-specified amount of time in seconds until current time. Since the event only lives for up to 5 minutes, you have now till 5 minutes in the past to query. This function supports seconds level of precision.

3. clearQueue() - will empty the queue and clear all the timeouts associated with it;

Usage

import {sendEvent, getEventsCountAtTime} from 'src/index.ts';
sendEvent();
console.log(getEventsAtTime(10)); // 1
setTimeout(() => console.log(getEventsAtTime(1)), FIVE_MINS) // 0
