Locale date format - token

[Joseph-Naveen]

How can I get the date format for the locale dynamically?
eg -
en-us -> 'MM/dd/yyyy',
de ->dd.MM.yyyy

I need to get this 'MM/dd/yyyy' format token dynamically

I think something like this would work .

You can also export this function for reusable usage.

const { format } = require("date-fns");
const { enUS, de, fr, es, it } = require("date-fns/locale");

const localeFormats = {
  "en-us": "MM/dd/yyyy",
  de: "dd.MM.yyyy",
  fr: "dd/MM/yyyy",
  es: "dd-MM-yyyy",
  it: "dd/MM/yyyy",
  // Add more locales and format strings as needed
};

function getLocaleFormat(locale) {
  return localeFormats[locale.toLowerCase()] || "MM/dd/yyyy"; // Default to a fallback format if not found
}

function formatDate(date, locale) {
  const formatStr = getLocaleFormat(locale);
  let localeObject;

  switch (locale.toLowerCase()) {
    case "en-us":
      localeObject = enUS;
      break;
    case "de":
      localeObject = de;
      break;
    case "fr":
      localeObject = fr;
      break;
    case "es":
      localeObject = es;
      break;
    case "it":
      localeObject = it;
      break;
    // Add more cases for additional locales
    default:
      localeObject = enUS; // Default to English (United States)
  }

  return format(date, formatStr, { locale: localeObject });
}

// Example usage
const date = new Date();
const localeEnUS = "en-us";
const localeDe = "de";
const localeFr = "fr";
const localeEs = "es";
const localeIt = "it";

console.log(formatDate(date, localeEnUS)); // Outputs 'MM/dd/yyyy'
console.log(formatDate(date, localeDe)); // Outputs 'dd.MM.yyyy'
console.log(formatDate(date, localeFr)); // Outputs 'dd/MM/yyyy'
console.log(formatDate(date, localeEs)); // Outputs 'dd-MM-yyyy'
console.log(formatDate(date, localeIt)); // Outputs 'dd/MM/yyyy'

Can I get this dynamically?
const localeFormats = {
"en-us": "MM/dd/yyyy",
de: "dd.MM.yyyy",
fr: "dd/MM/yyyy",
es: "dd-MM-yyyy",
it: "dd/MM/yyyy",
// Add more locales and format strings as needed
};

Currently, I'm unable to discover a dynamic solution for this. I trust someone will uncover the answer. In the meantime, feel free to utilize the provided solution.
