timeSolver.js

A small library for manipulating, validating and formatting JavaScript date object. Futhermore, it can helps you log your execution time by using timelook.

Current Version : v1.2.0

Getting Start

Installation

Install via npm or download source file directly

• npm

npm install timesolver

• source

https://github.com/sean1093/timeSolver/tree/master/src

Usage

You need to use timeSolver object to manipulate JavaScript date object.

Include timeSolver, You can use global object in your page.

<script type="text/javascript" src="timeSolver.min.js"></script>

You also can use via require.

const timeSolver = require('./../timeSolver');

const dateString = timeSolver.getString(new Date(), "YYYYMMDD");

Method

Add and Subtract

You can use this basic manipulate on date, add or subtract, by different time unit(type)

/**
 * Add time by time unit
 * 
 * @param {date/string} [date] standard JavaScript Date object or date string
 * @param {string} [count] a number you want to add on date
 * @param {string} [type] timeSolver time unit
 * @return {date} standard JavaScript Date object
 */
const afterAdd = timeSolver.add(date, count, type);

/**
 * Subtract time by time unit
 * 
 * @param {date/string} [date] standard JavaScript Date object or date string
 * @param {string} [count] a number you want to subtract on date
 * @param {string} [type] timeSolver time unit
 * @return {date} standard JavaScript Date object
 */
const afterSubtract = timeSolver.subtract(date, count, type);

Equal

/**
 * Check whether two dates equals or not 
 * 
 * @param {date/string} [date1] standard JavaScript Date object or date string
 * @param {date/string} [date2] standard JavaScript Date object or date string
 * @return {boolean} equals or not  
 */
const result = timeSolver.equal(date1, date2);

After

/**
 * Check whether date1 after date2 or not 
 * 
 * @param {date/string} [date1] standard JavaScript Date object or date string
 * @param {date/string} [date2] standard JavaScript Date object or date string
 * @return {boolean} date1 after date2 or not  
 */
const result = timeSolver.after(date1, date2, type);

After Today

/**
 * Check whether date after today or not 
 * 
 * @param {date/string} [date] standard JavaScript Date object or date string
 * @return {boolean} date1 after today or not  
 */
const result = timeSolver.afterToday(date);

Before

/**
 * Check whether date1 before date2 or not 
 * 
 * @param {date/string} [date1] standard JavaScript Date object or date string
 * @param {date/string} [date2] standard JavaScript Date object or date string
 * @return {boolean} date1 before date2 or not  
 */
const result = timeSolver.before(date1, date2, type);

Before Today

/**
 * Check whether date before today or not 
 * 
 * @param {date/string} [date] standard JavaScript Date object or date string
 * @return {boolean} date1 before today or not  
 */
const result = timeSolver.beforeToday(date);

Between

/**
 * Count time by time unit between two date 
 * 
 * @param {date/string} [date1] standard JavaScript Date object or date string
 * @param {date/string} [date2] standard JavaScript Date object or date string
 * @param {string} [type] timeSolver time unit
 * @return {number} return count by time unit 
 */
const result = timeSolver.between(date1, date2, type);

Get Date String

/**
 * Get date time string by different format 
 * 
 * @param {date/string} [date] standard JavaScript Date object or date string
 * @param {string} [format] timeSolver string format
 * @return {string} return formated string
 */
const dateString = timeSolver.getString(date, format);

timeSolver string format

Get Week and Month

Get date's weekday or month name, it will return abbr. or full name by different method

const result1 = timeSolver.getAbbrWeek(date);
const result2 = timeSolver.getFullWeek(date);
const result3 = timeSolver.getAbbrMonth(date);
const result4 = timeSolver.getFullMonth(date);

isValid

/**
 * Check whether date string is valid or not and return true/ false if dateString valid or not 
 * 
 * @param {string} [dateString] date string
 * @param {string} [format] timeSolver valid format
 * @return {boolean} dateString is valid or not
 */
const result = timeSolver.isValid(dateString, format);

timeSolver valid format

getQuarterByMonth

/**
 * Get quarter by give month
 * 
 * @param {number} [month] month number
 * @return {number} return quarter number
 */
const quarter = timeSolver.getQuarterByMonth(month);

getFirstMonthByQuarter

/**
 * Get quarter's first month string by give quarter
 * 
 * @param {number} [quarter] quarter number
 * @return {number} return month number
 */
const firstMonth = timeSolver.getFirstMonthByQuarter(quarter);

timeLook

It can helps you log your execution time by using timeLook

1. start timeLook

timeSolver.timeLookStart();

2. set your break point with label text

timeSolver.timeLook("test");
...
timeSolver.timeLook("date basic function");
...
...

3. see your time log report

timeSolver.timeLookReport();

For example, it will print on your browser console.

It will shows every execution time between your two break point, and mark the bottleneck with red color(Chrome Console).
