@push.rocks/smarttime

handle time in smart ways

Install

To install @push.rocks/smarttime, use the following npm command:

npm install @push.rocks/smarttime --save

This will add @push.rocks/smarttime to your project's dependencies.

Usage

@push.rocks/smarttime provides a comprehensive toolkit for handling various aspects of time manipulation, scheduling, and comparison in a TypeScript project. The following sections will guide you through the capabilities of this package, showcasing how to use its classes and functions effectively.

Handling Time Units and Calculations

Working with Units

import { units, getMilliSecondsFromUnits } from '@push.rocks/smarttime';

// Define a duration using a combination of time units
let durationInMilliseconds = getMilliSecondsFromUnits({
  years: 1,
  months: 2,
  weeks: 3,
  days: 4,
  hours: 5,
  minutes: 6,
  seconds: 7
});

console.log(`Duration in milliseconds: ${durationInMilliseconds}`);

In the example above, we specify a complex duration made up of various time units using the getMilliSecondsFromUnits function. This is quite useful for calculations where you need to define durations in a more human-readable format.

Scheduling with CronManager

@push.rocks/smarttime includes a powerful scheduling tool called CronManager, which allows you to schedule tasks using cron syntax.

Creating and Starting a CronManager

import { CronManager } from '@push.rocks/smarttime';

const cronManager = new CronManager();

// Adding a cron job that runs every minute
cronManager.addCronjob('* * * * *', async () => {
  console.log('This task runs every minute.');
});

// Starting the CronManager
cronManager.start();

The example demonstrates how to create a CronManager, add a cron job that runs every minute, and start the scheduling. You can add multiple cron jobs to a single manager, each with its own scheduling and task.

Working with Extended Date Class

The ExtendedDate class extends the native JavaScript Date object, providing additional functionality for handling dates in various formats and zones.

Creating ExtendedDate Instances

import { ExtendedDate } from '@push.rocks/smarttime';

// Creating a date from a European format string
const dateFromEuroString = ExtendedDate.fromEuropeanDate('31.12.2023');
console.log(dateFromEuroString.toString());

// Creating a date from a hyphed date string
const dateFromHyphedString = ExtendedDate.fromHyphedDate('2023-12-31');
console.log(dateFromHyphedString.toString());

Checking if a Date is Today

import { ExtendedDate } from '@push.rocks/smarttime';

const someDate = new ExtendedDate();
console.log(`Is someDate today? ${someDate.isToday()}`);

Using ExtendedDate, you can also easily check if a given date is today. This simplifies certain date comparisons that are common in web and application development.

High-Resolution Time Measurement

For performance testing and high-resolution time tracking, @push.rocks/smarttime provides the HrtMeasurement class.

import { HrtMeasurement } from '@push.rocks/smarttime';

const hrtMeasurement = new HrtMeasurement();
hrtMeasurement.start();
// Simulate some operations...
setTimeout(() => {
  hrtMeasurement.stop();
  console.log(`Operation took ${hrtMeasurement.milliSeconds} milliseconds.`);
}, 1000);

This class allows you to measure the duration of operations in your code with high precision, offering both milliseconds and nanoseconds resolutions.

Interval and Timer functionalities

@push.rocks/smarttime includes classes for managing intervals and timers with enhanced control, such as pause, resume, and reset capabilities.

Using the Timer class

import { Timer } from '@push.rocks/smarttime';

const timer = new Timer(5000); // A 5-second timer
timer.start();

timer.completed.then(() => {
  console.log('Timer completed!');
});

// Resetting the timer
timer.reset();
timer.start();

The Timer class allows for asynchronous waiting in a more object-oriented manner. In the example, a Timer is created for five seconds, started, and then reset for demonstration purposes.

Conclusion

@push.rocks/smarttime offers an extensive toolkit for dealing with time in JavaScript and TypeScript applications. Whether you need precise timing, scheduled tasks, or extended date functionalities, this package provides a suite of tools designed to handle time in smart and efficient ways. The examples provided herein demonstrate the core functionalities, aiming to help you integrate time-related features into your projects with ease.
