Importing DateTimeFormatOptions into Your Project

I have been trying to store a specific DateTimeFormatOptions for the date.toLocaleString() function so that I can easily use it in various parts of my application. Here is how I defined it:

export const timeFormat = { month: 'numeric', day: '2-digit', hour: '2-digit', minute: '2-digit', hour12: false, timeZoneName: 'short', timeZone: 'UTC'}

However, when I attempt to use it, I receive the following error:

Argument of type '{ month: string; day: string; hour: string; minute: string; hour12: boolean; timeZoneName: string; timeZone: string; }' is not assignable to parameter of type 'DateTimeFormatOptions'.
  Types of property 'month' are incompatible.
    Type 'string' is not assignable to type '"numeric" | "2-digit" | "short" | "long" | "narrow" | undefined'.

I have struggled with importing DateTimeFormatOptions and as a workaround, I have created a helper method to format the date. However, I may still need to import it in case users want to change their date preferences.

Answer №1

The information you're looking for is located within the Intl object. No need to worry about importing it. Simply specify the type as Intl.DateTimeFormatOptions.

To get the desired time format, use: const timeFormat: Intl.DateTimeFormatOptions = { month: 'numeric', day: '2-digit', hour: '2-digit', minute: '2-digit', hour12: false, timeZoneName: 'short', timeZone: 'UTC' }
