Localization
Localization
Materially supports four types of international languages ('en' - English, 'fr' - French, 'ro' - Romanian, 'zh' - Chinese). You can switch language from the header bar. We internationalize the main menu for all four languages, When you change it from the header, you will see the effect there. If you want to configure one more language or set a default language then continue reading below...
IntlProvider
React Intl uses the provider pattern to scope an i18n context to a tree of components. This allows configurations like the current locale and set of translated strings/messages to be provided at the root of a component tree and made available to the <FormattedMessage>
components.
locale, formats, and messages
The user's current locale and what the app should be rendered in. While defaultLocale
and defaultFormats
are for fallbacks or during development and represent the app's default. Notice how there is no, defaultMessages
that's because each Message Descriptor provides a defaultMessage
How does it work?
Add node modules react-intl
emo
yarn add react-intl / npm install --save react-intl
Data for locale files exist at src\utils\locales
{
"dashboard": "Dashboard",
"default": "Default",
"widget": "Widget",
"widgets": "Widgets",
"statistic": "Statistic",
...
...
}
Open the file config
and set the language.
const config: ConfigProps = {
mode: ThemeMode.LIGHT,
i18n: ThemeI18n.EN,
themeDirection: ThemeDirection.LTR
};
Open file Locales
and apply IntlProvider
import { ReactElement, useEffect, useState } from 'react';
// third party
import { IntlProvider, MessageFormatElement } from 'react-intl';
// project imports
import { ThemeI18n } from 'config';
import useConfig from 'hooks/useConfig';
import { ChildrenProps } from 'types/root';
// locales
const loadLocaleData = (locale: ThemeI18n) => {
switch (locale) {
case ThemeI18n.FR:
return import('utils/locales/fr.json');
case ThemeI18n.RO:
return import('utils/locales/ro.json');
case ThemeI18n.ZH:
return import('utils/locales/zh.json');
case ThemeI18n.EN:
default:
return import('utils/locales/en.json');
}
};
// ==============================|| LOCALIZATION ||============================== //
export default function Locales({ children }: ChildrenProps) {

loadLocaleData(i18n).then((d: { default: Record<string, string> | Record<string, MessageFormatElement[]> | undefined }) => {
