react-date-range-divider

A react component for divide a date interval into equally distributited intervals at a day level.

Installation

npm i react-date-range-divider --save

Usage

Quick Examples

import { DateRangeDivider, IMiddleDateInterval } from 'react-date-range-divider';
const FooComponent = () => {
    const [intervals, setIntervals] = useState<IMiddleDateInterval[]>([]);
    const numOfDivisios = 2;
    const startDate = new Date("2020/05/11"); // YYYY/MM/DD 
    const endDate = new Date("2020/05/15");  // YYYY/MM/DD 
    return (
        <DateRangeDivider
            divisions={numOfDivisios}
            startDate={startDate}
            endDate={endDate}
            onDivisionsChange={(resultIntervals: IMiddleDateInterval[]) => {
                // Do what you need with intervals
                setIntervals(() => resultIntervals);
            }}
        />
    )
};

Warning

Since it divides in entire days a non possible Int division (with no decimals in result) will aproximate the first interval to the next day. In this case the result will be:

11/05/2020 - 00:00:00 => 13/05/2020 - 23:59:59 (3 days including start and end)
14/05/2020 - 00:00:00 => 14/05/2020 - 23:59:59 (2 days including start and end)

5 days in total from 11/05/2020 - 15/05/2020. (DD/MM/YYYY)

calcRegularIntervals Function

If only need to divide intervals without the component, the function can be imported alone.

import { calcRegularIntervals, IMiddleDateInterval } from 'react-date-range-divider';

const startDate = new Date("2020/05/11"); // YYYY/MM/DD 
const endDate = new Date("2020/05/15");  // YYYY/MM/DD 
const numOfDivisios = 2;

const intervals: IMiddleDateInterval[] = calcRegularIntervals(startDate, endDate, numOfDivisios); // number to divide is 1 by default

Documentation

Import

import { DateRangeDivider } from 'react-date-range-divider';

Error Handler

By passing a endDate lower than the startDate or giving a divisionNumber higher than the number of days in between parent interval, the component will use the current day divided in one

Props

Name	Type	Description
divisions	number	Number of division desired of the given period (If this number is higher than the number of days available in the period will take 1 as default)
startDate	Date	Start date of the parent interval (will convert to the beggining of the passes day. ex: 2020/05/14:12:14:00 => 2020/05/14-00:00:00)
endDate	Date	Finish Date of the parent interval (will convert to the beggining of the passes day. ex: 2020/05/14:12:14:00 => 2020/05/14-23:59:59)
onDivisionsChange	(intervals: IMiddleDateInterval[]) => void	callback that passes the resultant intervals as argument

Types

Name	Type	Description
IMiddleDateInterval	{start: Date, end: Date}	Dates resultant of division calculus
