🚀 Why Flexidatepicker Matters

Date selection interfaces are a common pain point in web development, often plagued by clunky user experiences, limited customization, and inconsistent behavior across browsers. Users expect intuitive, responsive, and accessible experiences that adapt to their needs, while developers frequently face rigid libraries that require extensive workarounds for basic functionality. Flexidatepicker addresses these challenges with a lightweight, framework-agnostic solution designed for modern web applications. Its core strengths include:

  • Zero-configuration setup: Ready to use out-of-the-box while still offering deep customization for advanced use cases
  • Multi-calendar support: Enables side-by-side date comparisons and complex range selections
  • Dynamic theming: Adapts to your application's design system with minimal CSS overrides
  • Seamless localization: Built-in support for 30+ languages and regional calendar conventions
  • Performance-optimized: Under 10KB gzipped, with lazy-loaded calendar components

This library empowers developers to create date selection experiences that are both user-friendly and maintainable, reducing the need for custom date parsing logic and browser-specific fixes. Whether you're building a simple form or a complex international booking system, Flexidatepicker provides the flexibility to meet diverse user requirements while maintaining code simplicity.

  • Zero configuration required
  • Multi-calendar support
  • Dynamic theming
  • Seamless localization

🛠️ Installation & Basic Setup

CDN Quickstart

For rapid prototyping, include the CDN in your HTML:

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/flexidatepicker@latest/dist/flexidatepicker.min.css">
<script src="https://cdn.jsdelivr.net/npm/flexidatepicker@latest/dist/flexidatepicker.min.js"></script>

Initialize with a single line of JavaScript:

const picker = new Flexidatepicker('#date-input');
Enter fullscreen mode Exit fullscreen mode

NPM Integration

For production applications, install via NPM:

npm install flexidatepicker
Enter fullscreen mode Exit fullscreen mode

Import and configure in your JavaScript:

import Flexidatepicker from 'flexidatepicker';
import 'flexidatepicker/dist/flexidatepicker.min.css';

const picker = new Flexidatepicker(document.getElementById('date-input'), {
  mode: 'range',
  minDate: 'today'
});
Enter fullscreen mode Exit fullscreen mode

🎛️ Core Configuration Options

Date Selection Modes

Note: All configuration options are optional and can be combined based on your application requirements.

Date Restrictions

Control available dates with these parameters:

new Flexidatepicker('#input', {
  minDate: '2023-11-01',
  maxDate: '2023-12-31',
  disabledDates: ['2023-11-25', '2023-11-26'],
  weekendsDisabled: true
});
Enter fullscreen mode Exit fullscreen mode

Example implementation:

new Flexidatepicker('#calendar', {
  mode: 'range',
  dateFormat: 'Y-m-d',
  weekStart: 1 // Monday-first week
});
Enter fullscreen mode Exit fullscreen mode

Date Restrictions

Control available dates with these parameters:

new Flexidatepicker('#input', {
  minDate: '2023-11-01',
  maxDate: '2023-12-31',
  disabledDates: ['2023-11-25', '2023-11-26'],
  weekendsDisabled: true
});
Enter fullscreen mode Exit fullscreen mode

🎨 Custom Theming & Styling

Applying Themes

Flexidatepicker comes with three built-in themes:

// Light theme (default)
import 'flexidatepicker/dist/themes/light.css';

// Dark theme
import 'flexidatepicker/dist/themes/dark.css';

// Custom theme
import 'flexidatepicker/dist/themes/material.css';
Enter fullscreen mode Exit fullscreen mode

Custom CSS Overrides

Use the theme configuration to apply your own styles:

new Flexidatepicker('#custom', {
  theme: {
    primaryColor: '#FF6B6B',
    headerBackground: '#2c3e50',
    disabledOpacity: 0.3
  }
});
Enter fullscreen mode Exit fullscreen mode

🌍 Localization & I18n

Language Support

Easily switch locales using the locale configuration:

new Flexidatepicker('#international', {
  locale: 'es-ES', // Spanish (Spain)
  weekLabel: 'Semana', // Custom week label
  monthNames: ['Enero', 'Febrero', ...] // Custom month names
});
Enter fullscreen mode Exit fullscreen mode

Right-to-Left Support

Activate RTL layout for languages like Arabic:

new Flexidatepicker('#rtl', {
  rtl: true,
  locale: 'ar-SA',
  calendarPosition: 'right'
});
Enter fullscreen mode Exit fullscreen mode

🧩 Framework Integration

React Component

Create a reusable component wrapper:

import React, { useEffect, useRef } from 'react';
import Flexidatepicker from 'flexidatepicker';

const DatePickerController = () => {
  const inputRef = useRef(null);

  useEffect(() => {
    new Flexidatepicker(inputRef.current, {
      mode: 'single'
    });
  }, []);

  return <input ref={inputRef} type="text" />;
};
Enter fullscreen mode Exit fullscreen mode

Vue 3 Composition API 

import { ref, onMounted } from 'vue';
import Flexidatepicker from 'flexidatepicker';

export default {
  setup() {
    const dateInput = ref(null);

    onMounted(() => {
      new Flexidatepicker(dateInput.value, {
        minDate: '2023-11-01'
      });
    });

    return { dateInput };
  }
};
Enter fullscreen mode Exit fullscreen mode

✅ Best Practices

  1. Always set minDate and maxDate for business logic constraints
  2. Use weekStart to match regional calendar conventions
  3. Combine with form validation libraries for robust date checks
  4. Test with screen readers for accessibility compliance

Remember: Date pickers should guide users, not trap them. Always provide manual input options.

Note: Consider using dynamic theming to maintain visual consistency with your application's design system while enhancing user experience.
