React Kronology

A fork of react-kronos

A fast, intuitive, and elegant date and time picker for React.

Philosophy

• Works straight out of the box with minimal props
• Provide a few props and options that give lots of control
• Allow for granular control when needed
• Style is done in JS and can be easily modified
• Beautiful code and appearance

Rationale

Even though there are many React Date and/or Time components, I'm developing my own because none of them do everything that I need.

Key requirements:

• Separate date and/or time components (many only have date)
• Easily style-able from JS (not have to muck around in the css)
• Return multiple time formats (Date, Moment, ISO, string)
• Lightweight, use no jquery
• Active on focus, disappear on blur
• Efficient keyboard navigation

Demo

Usage

1. NPM install npm install @commander-lol/react-kronos
2. Require Kronos import Kronos from '@commander-lol/react-kronos'
3. Use

<Kronos
  date={this.state.datetime}
  onChange={this.onChange}
/>

Props:

• date - Date(), Moment(), ISO, or string (if string, must match format)
• time - Date(), Moment(), ISO, or string (if string, must match format)
• timeStep - number : minutes for time step (if not specified: 30 minutes)
• format - string : Moment formatting of date / time
• onChange - function : native onChange method
• onChangeDateTime - function : change method called when there is a new value
• returnAs - string : onChange format JS_DATE, MOMENT, ISO, STRING (default: same as input)
• min - Date(), Moment(), ISO to set as the minimum datetime
• max - Date(), Moment(), ISO to set as the maximum datetime
• minTime - Date(), Moment(), ISO to set as the minimum time (only the time will be used)
• maxTime - Date(), Moment(), ISO to set as the maximum time (only the time will be used)
• closeOnSelect - boolean : closes the dropdown when a value is selected (default: true)
• closeOnBlur - boolean : closes the dropdown when the field is blurred (default: true)
• disabled - boolean : whether or not the input component is disabled. If true, the selector will not be visible regardless of the setting of visible
• shouldTriggerOnChangeForDateTimeOutsideRange - boolean: optionally allow dates outside min/max range to trigger onChanges (default: false)
• preventClickOnDateTimeOutsideRange - boolean: optionally prevent users from clicking on dates outside min/max range (default: false)
• hideOutsideDateTimes - boolean: optionally hide times that do not pass validation (default: false)
• placeholder - string : placeholder text when there is no value
• name - string : name used for the input form
• disabled - boolean : prevent interaction with input field
• inputStyle - object : inline styles for input field
• inputClassName - string : .class for input field
• inputId - string : #id for input field
• calendarStyle - object : inline styles for calendar
• calendarClassName - string : .class for calendar
• options:
  • color - string : the highlight color in the UI as a hex
  • corners - number : the pixel size of rounded corners (default: 4)
  • font - string : the font family (default: Source Sans Pro)
  • locale - object : Moment locale customization
    • lang - string : language (default: en for english)
    • settings - object : properties to override as an object (default: { week: { dow: 1 }, weekdaysMin: ['M', 'T', 'W', 'T', 'F', 'S', 'S'] })
  • format: - object : Moment formatting for cell titles
    • today: - string : default: Today
    • year: - string : default: YYYY
    • month: - string : default: MMM
    • day: - string : default: D
    • hour: - string : default: h:mm a

Construction progress

Roadmap

Needed

• Provide docs on website
• options:
  • date (restrict calendar to show only days, or with months, or with years)
  • time (set increments, set ranges of time)
• support for connected start & end date+time
  • date (show range on calendar)
  • time (show "0 hours", "0.5 hours", "1 hour", &c)

Ideas

• input field masking
• ⇧+arrow uses the higher order unit
• specify required props & non-required (what happens if none are included)
• add warning messages to help use component properly
• mobile support
• wide browser compatibility
• prop: styles - granular styling (overwrite any style, or provide entire theme)
• add crazy awesome date/time interpretation/parsing similar to that in The Hit List
• set up solid unit tests
