* @name setDefaultOptions
|
|
* @category Common Helpers
|
|
* @summary Set default options including locale.
|
|
* @pure false
|
|
*
|
|
* @description
|
|
* Sets the defaults for
|
|
* `options.locale`, `options.weekStartsOn` and `options.firstWeekContainsDate`
|
|
* arguments for all functions.
|
|
*
|
|
* @param options - An object with options
|
|
*
|
|
* @example
|
|
* // Set global locale:
|
|
* import { es } from 'date-fns/locale'
|
|
* setDefaultOptions({ locale: es })
|
|
* const result = format(new Date(2014, 8, 2), 'PPPP')
|
|
* //=> 'martes, 2 de septiembre de 2014'
|
|
*
|
|
* @example
|
|
* // Start of the week for 2 September 2014:
|
|
* const result = startOfWeek(new Date(2014, 8, 2))
|
|
* //=> Sun Aug 31 2014 00:00:00
|
|
*
|
|
* @example
|
|
* // Start of the week for 2 September 2014,
|
|
* // when we set that week starts on Monday by default:
|
|
* setDefaultOptions({ weekStartsOn: 1 })
|
|
* const result = startOfWeek(new Date(2014, 8, 2))
|
|
* //=> Mon Sep 01 2014 00:00:00
|
|
*
|
|
* @example
|
|
* // Manually set options take priority over default options:
|
|
* setDefaultOptions({ weekStartsOn: 1 })
|
|
* const result = startOfWeek(new Date(2014, 8, 2), { weekStartsOn: 0 })
|
|
* //=> Sun Aug 31 2014 00:00:00
|
|
*
|
|
* @example
|
|
* // Remove the option by setting it to `undefined`:
|
|
* setDefaultOptions({ weekStartsOn: 1 })
|
|
* setDefaultOptions({ weekStartsOn: undefined })
|
|
* const result = startOfWeek(new Date(2014, 8, 2))
|
|
* //=> Sun Aug 31 2014 00:00:00
