Example Usage

Basic Usage

import { getTranslationContent, Locales } from "intlayer";const content = getTranslationContent(  {    en: "Hello",    fr: "Bonjour",  },  Locales.ENGLISH);console.log(content); // Output: "Bonjour"

Missing Locale:

import { getTranslationContent, Locales } from "intlayer";const content = getTranslationContent(  {    en: "Hello",    fr: "Bonjour",  },  Locales.SPANISH);console.log(content); // Output: "Hello" (default locale content)

Using Custom Content Types:

import { getTranslationContent, Locales } from "intlayer";const customContent = getTranslationContent<Record<string, string>>(  {    en: { greeting: "Hello" },    fr: { greeting: "Bonjour" },  },  Locales.FRENCH);console.log(customContent.greeting); // Output: "Bonjour"

Edge Cases

• Locale Not Found:
  • When the locale is not found in the languageContent, the function returns the content for the default locale.
• Incomplete Language Content:
  • If a locale is partially defined, the function does not merge contents. It strictly retrieves the value of the specified locale or falls back to the default.
• TypeScript Enforcement:
  • If the locales in languageContent do not match the project configuration, TypeScript will enforce all required locales to be defined, ensuring the content is complete and type-safe.
