Basic Usage

Here’s how you can start using php-js-dateformat

Formatting Dates

import dateFormat from 'php-js-dateformat';  

const date = new Date();  

console.log(dateFormat(date, 'Y-m-d H:i:s'));  
// Output: 2024-11-23 15:30:45  

Escaping Characters

• Single Characters: Use a backslash (\) to escape characters.

  console.log(dateFormat(date, '\\Y Y-m-d H:i:s'));  
  // Output: Y 2024-11-23 15:30:45  

• Character Sets: Use curly braces ({}) to escape a set of characters.

  console.log(dateFormat(date, '{Date:} Y-m-d H:i:s'));  
  // Output: Date: 2024-11-23 15:30:45

Supported Format Characters

php-js-dateformat supports most of the format characters found in PHP's date format function, including:

• Year: Y, y
• Month: m, n, F, M
• Day: d, j, l, D
• Hour: H, h, G, g
• Minute: i
• Second: s
• And more...

For a full list, refer to the PHP Documentation.

Unsupported Parameters

Due to limitations in the browser's Date API, some parameters behave differently:

• Timezone-related Parameters: O, P, p, and T always return the local timezone.
• Microseconds (v): Always returns milliseconds * 1000 as true microseconds are not supported.
• T (Timezone Abbreviation): Returns the same as O. For actual timezone abbreviations, use:

  import { getTimezoneByName } from 'php-js-dateformat/timezone';  
  
  const timezoneInfo = getTimezoneByName('Asia/Calcutta');  
  console.log(timezoneInfo?.abbr); // Output: IST (or `undefined`)
