Pros of bootstrap-datepicker

• Lightweight and focused on single date selection
• Extensive localization support with 60+ languages
• Better integration with Bootstrap's styling

Cons of bootstrap-datepicker

• Lacks built-in date range selection functionality
• Less feature-rich compared to daterangepicker
• Requires additional customization for advanced use cases

Code Comparison

bootstrap-datepicker:

$('#datepicker').datepicker({
    format: 'mm/dd/yyyy',
    startDate: '-3d'
});

daterangepicker:

$('input[name="daterange"]').daterangepicker({
    startDate: moment().subtract(7, 'days'),
    endDate: moment(),
    ranges: {
       'Today': [moment(), moment()],
       'Yesterday': [moment().subtract(1, 'days'), moment().subtract(1, 'days')],
       'Last 7 Days': [moment().subtract(6, 'days'), moment()],
       'Last 30 Days': [moment().subtract(29, 'days'), moment()],
       'This Month': [moment().startOf('month'), moment().endOf('month')],
       'Last Month': [moment().subtract(1, 'month').startOf('month'), moment().subtract(1, 'month').endOf('month')]
    }
});

The code comparison shows that bootstrap-datepicker is simpler to implement for basic date selection, while daterangepicker offers more advanced features like predefined ranges and date range selection out of the box.

Pros of Tempus Dominus

• More comprehensive date and time picker with additional features like time selection and date ranges
• Modern UI with customizable themes and localization support
• Active development and regular updates

Cons of Tempus Dominus

• Steeper learning curve due to more complex configuration options
• Larger file size and potentially higher performance overhead
• May be overkill for simple date picking needs

Code Comparison

DateRangePicker:

$('input[name="daterange"]').daterangepicker({
  startDate: '01/01/2023',
  endDate: '12/31/2023'
});

Tempus Dominus:

new tempusDominus.TempusDominus(document.getElementById('datetimepicker'), {
  display: {
    components: {
      calendar: true,
      date: true,
      month: true,
      year: true,
      decades: true,
      clock: true,
      hours: true,
      minutes: true,
      seconds: true
    }
  }
});

Both libraries offer date picking functionality, but Tempus Dominus provides more granular control over the components displayed and supports time selection out of the box. DateRangePicker has a simpler API for basic date range selection, while Tempus Dominus offers more flexibility at the cost of increased complexity.

Pros of flatpickr

• Lightweight and dependency-free (only 6.7KB gzipped)
• Supports a wide range of date and time formats
• Highly customizable with extensive theming options

Cons of flatpickr

• Lacks built-in date range selection functionality
• May require additional plugins for advanced features

Code Comparison

flatpickr:

flatpickr("#myDatePicker", {
  enableTime: true,
  dateFormat: "Y-m-d H:i",
  minDate: "today"
});

daterangepicker:

$('#myDatePicker').daterangepicker({
  timePicker: true,
  startDate: moment().startOf('hour'),
  endDate: moment().startOf('hour').add(32, 'hour'),
  locale: {
    format: 'YYYY-MM-DD HH:mm'
  }
});

Key Differences

• flatpickr is more lightweight and doesn't require jQuery
• daterangepicker has built-in date range functionality
• flatpickr offers more customization options out of the box
• daterangepicker relies on Moment.js for date manipulation

Both libraries are popular choices for date and time picking in web applications, with flatpickr being more suitable for simple date/time selection and daterangepicker excelling in range selection scenarios.

Pros of Pikaday

• Lightweight and dependency-free (pure JavaScript)
• Highly customizable appearance and behavior
• Supports both mouse and keyboard navigation

Cons of Pikaday

• Limited to single date selection (no built-in date range functionality)
• Requires more manual configuration for advanced use cases
• Less extensive documentation compared to DateRangePicker

Code Comparison

Pikaday:

var picker = new Pikaday({
    field: document.getElementById('datepicker'),
    format: 'D MMM YYYY',
    onSelect: function(date) {
        console.log(date);
    }
});

DateRangePicker:

$('input[name="daterange"]').daterangepicker({
    startDate: '01/01/2023',
    endDate: '12/31/2023'
}, function(start, end, label) {
    console.log("A new date range was chosen: " + start.format('YYYY-MM-DD') + ' to ' + end.format('YYYY-MM-DD'));
});

The code examples demonstrate the basic setup for each library. Pikaday focuses on single date selection with a simple configuration, while DateRangePicker provides built-in support for selecting date ranges and offers more options out of the box.

Pros of Rome

• Lightweight and dependency-free, making it easier to integrate into projects
• Highly customizable with a modular architecture
• Supports both date and time picking in a single component

Cons of Rome

• Less actively maintained, with fewer recent updates
• Smaller community and fewer resources available for support
• Limited built-in themes and styling options

Code Comparison

DateRangePicker:

$('input[name="daterange"]').daterangepicker({
    startDate: '01/01/2023',
    endDate: '12/31/2023'
});

Rome:

rome(input, {
    dateValidator: rome.val.beforeEq(rome.moment().add(1, 'months')),
    timeValidator: rome.val.afterEq('09:00', '17:00')
});

DateRangePicker offers a more straightforward API for selecting date ranges, while Rome provides more granular control over date and time validation. Rome's approach allows for more complex scenarios but may require more setup code.

Both libraries have their strengths, with DateRangePicker being more popular and actively maintained, while Rome offers a lighter footprint and more flexibility. The choice between them depends on specific project requirements, such as the need for time picking, dependency management, and desired level of customization.

Pros of react-dates

• Built specifically for React, offering seamless integration with React applications
• Highly customizable with a wide range of props and theming options
• Extensive documentation and examples for easy implementation

Cons of react-dates

• Larger bundle size due to its comprehensive feature set
• Steeper learning curve for developers new to React or complex date-picking components

Code Comparison

react-dates:

import React from 'react';
import { DateRangePicker } from 'react-dates';

const MyComponent = () => (
  <DateRangePicker
    startDate={startDate}
    endDate={endDate}
    onDatesChange={({ startDate, endDate }) => {
      setStartDate(startDate);
      setEndDate(endDate);
    }}
    focusedInput={focusedInput}
    onFocusChange={focusedInput => setFocusedInput(focusedInput)}
  />
);

daterangepicker:

$('input[name="daterange"]').daterangepicker({
  opens: 'left',
  startDate: '01/01/2023',
  endDate: '12/31/2023'
}, function(start, end, label) {
  console.log("A new date selection was made: " + start.format('YYYY-MM-DD') + ' to ' + end.format('YYYY-MM-DD'));
});

The code comparison highlights the different approaches: react-dates uses a React component with props, while daterangepicker uses jQuery and a configuration object.
