  5. * @name setDefaultOptions
  6. * @category Common Helpers
  7. * @summary Set default options including locale.
  8. * @pure false
  9. *
  10. * @description
  11. * Sets the defaults for
  12. * `options.locale`, `options.weekStartsOn` and `options.firstWeekContainsDate`
  13. * arguments for all functions.
  14. *
  15. * @param options - An object with options
  16. *
  17. * @example
  18. * // Set global locale:
  19. * import { es } from 'date-fns/locale'
  20. * setDefaultOptions({ locale: es })
  21. * const result = format(new Date(2014, 8, 2), 'PPPP')
  22. * //=> 'martes, 2 de septiembre de 2014'
  23. *
  24. * @example
  25. * // Start of the week for 2 September 2014:
  26. * const result = startOfWeek(new Date(2014, 8, 2))
  27. * //=> Sun Aug 31 2014 00:00:00
  28. *
  29. * @example
  30. * // Start of the week for 2 September 2014,
  31. * // when we set that week starts on Monday by default:
  32. * setDefaultOptions({ weekStartsOn: 1 })
  33. * const result = startOfWeek(new Date(2014, 8, 2))
  34. * //=> Mon Sep 01 2014 00:00:00
  35. *
  36. * @example
  37. * // Manually set options take priority over default options:
  38. * setDefaultOptions({ weekStartsOn: 1 })
  39. * const result = startOfWeek(new Date(2014, 8, 2), { weekStartsOn: 0 })
  40. * //=> Sun Aug 31 2014 00:00:00
  41. *
  42. * @example
  43. * // Remove the option by setting it to `undefined`:
  44. * setDefaultOptions({ weekStartsOn: 1 })
  45. * setDefaultOptions({ weekStartsOn: undefined })
  46. * const result = startOfWeek(new Date(2014, 8, 2))
