React Integration: useLocale Hook Documentation

This section provides comprehensive details on the useLocale hook from the react-intlayer library, designed for handling locale management in React applications.

Importing useLocale in React

To integrate the useLocale hook into your React application, import it from its respective package:

import { useLocale } from "react-intlayer"; // Used in React components for locale management

Overview

The useLocale hook offers an easy way to access and manipulate the locale settings within React components. It provides access to the current locale, the default locale, all available locales, and functions to update the locale settings.

Usage

Here’s how you can use the useLocale hook within a React component:

import type { FC } from "react";import { useLocale } from "react-intlayer";const LocaleSwitcher: FC = () => {  const { locale, defaultLocale, availableLocales, setLocale } = useLocale();  return (    <div>      <h1>Current Locale: {locale}</h1>      <p>Default Locale: {defaultLocale}</p>      <select value={locale} onChange={(e) => setLocale(e.target.value)}>        {availableLocales.map((loc) => (          <option key={loc} value={loc}>            {loc}          </option>        ))}      </select>    </div>  );};export default LocaleSwitcher;

Parameters and Return Values

When you invoke the useLocale hook, it returns an object containing the following properties:

• locale: The current locale as set in the React context.
• defaultLocale: The primary locale defined in the configuration.
• availableLocales: A list of all locales available as defined in the configuration.
• setLocale: A function to update the current locale within the application's context.

Example

This example shows a component that uses the useLocale hook to render a locale switcher, allowing users to dynamically change the locale of the application:

import type { FC } from "react";import { useLocale } from "react-intlayer";const LocaleSelector: FC = () => {  const { locale, setLocale, availableLocales } = useLocale();  const handleLocaleChange = (newLocale) => {    setLocale(newLocale);  };  return (    <select value={locale} onChange={(e) => handleLocaleChange(e.target.value)}>      {availableLocales.map((locale) => (        <option key={locale} value={locale}>          {locale}        </option>      ))}    </select>  );};

Conclusion

The useLocale hook from react-intlayer is an essential tool for managing locales in your React applications, providing the functionality needed to adapt your application to various international audiences effectively.
