import DateTimePicker from 'react-datetime-picker';
import { useEffect, useState } from 'react';

export function SSRDateTimePicker() {
  // Ensure locale matches between server and client
  const [mounted, setMounted] = useState(false);
  const [locale, setLocale] = useState('en-US');

  useEffect(() => {
    // Get actual browser locale on client
    setLocale(navigator.language);
    setMounted(true);
  }, []);

  if (!mounted) {
    // Return null or placeholder to prevent hydration mismatch
    return null;
  }

  return (
    <DateTimePicker

### Optimize Performance with Limited Open Widgets

Source: https://github.com/wojtekmaj/react-datetime-picker/blob/main/_autodocs/patterns-and-troubleshooting.md

To mitigate performance degradation when rendering many pickers, limit the number of simultaneously open widgets. Use state to control which picker is open and manage its visibility.

```tsx
function MultiplePickersOptimized() {
  const [openWidget, setOpenWidget] = useState<string | null>(null);

  return (
    <>
      <DateTimePicker
        isCalendarOpen={openWidget === 'picker1'}
        shouldOpenWidgets={() => openWidget === null}
        shouldCloseWidgets={() => true}
        onCalendarOpen={() => setOpenWidget('picker1')}
        onCalendarClose={() => setOpenWidget(null)}
      />
      <DateTimePicker
        isCalendarOpen={openWidget === 'picker2'}
        shouldOpenWidgets={() => openWidget === null}
        shouldCloseWidgets={() => true}

  );
}
```

--------------------------------

### Enforce Min/Max Dates Correctly

Source: https://github.com/wojtekmaj/react-datetime-picker/blob/main/_autodocs/patterns-and-troubleshooting.md

When setting minDate or maxDate, ensure they represent the start of the day to avoid unexpected behavior due to time components. Use a consistent timezone for date comparisons.

```tsx
const today = new Date();
const tomorrow = new Date(today);
tomorrow.setDate(tomorrow.getDate() + 1);

// ❌ If today is currently 3 PM, minDate is already in the past
<DateTimePicker minDate={today} />

// ✅ Set to start of day
const startOfToday = new Date(today.getFullYear(), today.getMonth(), today.getDate());
<DateTimePicker minDate={startOfToday} />
```

```tsx
// ❌ Date comparison may fail due to timezone
const minDate = new Date('2024-06-15');  // UTC

// ✅ Use consistent timezone
const minDate = new Date();
minDate.setFullYear(2024, 5, 15);  // June 15, 2024 in local time
```

### Troubleshooting: Calendar/Clock Not Opening

Source: https://github.com/wojtekmaj/react-datetime-picker/blob/main/_autodocs/patterns-and-troubleshooting.md

Addresses issues where the calendar or clock widgets do not appear when expected. This includes checking `disableCalendar`, `disableClock`, `shouldOpenWidgets`, and `openWidgetsOnFocus` properties.

```tsx
// ❌ Won't show calendar
<DateTimePicker disableCalendar={true} />

// ✅ Correct
<DateTimePicker disableCalendar={false} />

```

```tsx
// ❌ Prevents all opens
<DateTimePicker shouldOpenWidgets={() => false} />

// ✅ Correct
<DateTimePicker
  shouldOpenWidgets={({ reason, widget }) => {
    return reason === 'buttonClick';  // Only button clicks
  }}
/>

```

```tsx
// ❌ Can't open widget if no button and openWidgetsOnFocus=false
<DateTimePicker openWidgetsOnFocus={false} calendarIcon={null} />

// ✅ Provide alternate way to open
<DateTimePicker calendarIcon="📅" openWidgetsOnFocus={false} />

```

--------------------------------

### Filtered Options (Manual Implementation)

Source: https://github.com/wojtekmaj/react-datetime-picker/blob/main/_autodocs/patterns-and-troubleshooting.md

Manually implement filtering for DateTimePicker to restrict selections to specific business hours (weekdays, 9 AM - 5 PM). This example demonstrates custom validation logic within the `onChange` handler.

```tsx
import { useState } from 'react';
import DateTimePicker from 'react-datetime-picker';

function FilteredTimePicker() {
  const [value, setValue] = useState<Date | null>(null);

  // Business hours: 9 AM - 5 PM, Monday-Friday
  const isValidTime = (date: Date): boolean => {
    const hour = date.getHours();
    const day = date.getDay();

    // Monday = 1, Friday = 5, exclude weekends (0 = Sunday, 6 = Saturday)
    const isWeekday = day >= 1 && day <= 5;

    // 9 AM to 5 PM
    const isBusinessHours = hour >= 9 && hour < 17;

    return isWeekday && isBusinessHours;
  };

  const handleChange = (newValue: Date | null) => {
    if (newValue && !isValidTime(newValue)) {
      alert('Please select a weekday between 9 AM and 5 PM');
      return;
    }
    setValue(newValue);
  };

  const today = new Date();
  const nextMonth = new Date(today.getFullYear(), today.getMonth() + 1, today.getDate());

  return (
    <DateTimePicker
      value={value}
      onChange={handleChange}
      minDate={today}
      maxDate={nextMonth}
      maxDetail="minute"
    />
  );
}

```

--------------------------------

```

--------------------------------

### Handle SSR Hydration Mismatch with Client-Side Locale

Source: https://github.com/wojtekmaj/react-datetime-picker/blob/main/_autodocs/patterns-and-troubleshooting.md

For SSR frameworks like Next.js, ensure consistent locale by setting it on the client using `useEffect`. This example uses the 'use client' directive for Next.js 13+ App Router.

```tsx
'use client';  // Next.js 13+ App Router

import { useEffect, useState } from 'react';
import DateTimePicker from 'react-datetime-picker';

function SSRDateTimePicker() {
  const [mounted, setMounted] = useState(false);
  const [locale, setLocale] = useState('en-US');

  useEffect(() => {
    // Set locale to actual browser locale on client
    setLocale(navigator.language);
    setMounted(true);
  }, []);

  // Don't render on server to avoid mismatch
  if (!mounted) return null;

  return (
    <DateTimePicker
      locale={locale}
      format="yyyy-MM-dd HH:mm"
      value={null}
    />
  );
}
```

--------------------------------

```text
getFormatter({ month: 'long' })
    ↓
Check formatterCache for this locale + options
    ↓
If cached: return cached formatter function
    ↓
If not cached: create new Intl.DateTimeFormat
    ↓
Cache it
    ↓
Return formatter function
    ↓
Future calls with same locale + options hit cache (O(1))
```

  const today = new Date();
  const nextWeek = new Date(today.getTime() + 7 * 24 * 60 * 60 * 1000);

  return (
    <DateTimePicker
      minDate={today}
      maxDate={nextWeek}
      onChange={setValue}
      value={value}
    />
  );
}
```

--------------------------------

### Create a locale-aware year-month formatter

Source: https://github.com/wojtekmaj/react-datetime-picker/blob/main/_autodocs/api-reference/Utilities.md

Use `getFormatter` with appropriate options to create a function that formats both the year and month. This formatter is cached.
