Simple translation module for React applications.
- Install by executing
npm install @wojtekmaj/react-t
oryarn add @wojtekmaj/react-t
. - Setup by adding
import { TProvider } from '@wojtekmaj/react-t'
and wrapping your app in<TProvider />
. - Add languages by creating a JSON file, like this:
and adding
{ "Hello world!": "Hallo Welt!" }
languageFiles
to<TProvider />
, like this:<TProvider languageFiles={{ 'de-DE': () => import('./de-DE.json') }} />
- Use by adding
import T from '@wojtekmaj/react-t'
and wrapping your text in<T />
.
Your project needs to use React 16.8 or later.
React-T is also compatible with React Native.
Add React-T to your project by executing npm install @wojtekmaj/react-t
or yarn add @wojtekmaj/react-t
.
Here's an example of basic setup:
import { createRoot } from 'react-dom/client';
import { TProvider } from '@wojtekmaj/react-t';
import Root from './Root';
const languageFiles = {
'de-DE': () => import('./de-DE.json'),
};
createRoot(document.getElementById('react-root')).render(
<TProvider languageFiles={languageFiles}>
<Root />
</TProvider>,
);
Here's an example of basic usage:
import T from '@wojtekmaj/react-t';
function MyComponent() {
return (
<p>
<T>Hello world!</T>
</p>
);
}
React-T detects locale to use by going through the list of possible sources:
locale
prop provided to<TProvider />
<html lang="…">
attribute- List of preferred user locales obtained using
get-user-locale
On each step, React-T checks if a given locale is supported (provided in languageFiles
, or defined as defaultLocale
). If a given locale is supported, it'll use it. If not, it'll move to the next step on the list.
If no supported locale is detected, defaultLocale
is used (no translation is being made).
Wrap your app in <TProvider />
.
Define languageFiles
prop that contains an object of:
- functions that return promises:
{ 'de-DE': () => import('./myLanguageFile.json'), }
- functions that return language files:
{ 'de-DE': () => myLanguageFile, }
- language files:
{ 'de-DE': myLanguageFile, }
If you want T
and useTranslation
to trigger Suspense, provide suspend
prop to <TProvider />
and wrap your app in <Suspense />
.
If you want to override locale, wrap components that should use a different locale in another <TProvider />
with locale
prop provided. Other props like languageFiles
will be inherited from the parent <TProvider />
.
<TProvider>
<ThisComponentWillUseDefaultLocale />
<TProvider locale="de-DE">
<AndThisComponentWillUseGermanLocale />
</TProvider>
</TProvider>
Define translatable string in the code using <T>
tag:
<T>Original phrase</T>
If necessary, you may use variables like so:
<T name={name}>{'Hello, {name}'}</T>
Define translatable string in the code using useTranslation
hook:
const translatedPhrase = useTranslation('Original phrase');
If necessary, you may use variables like so:
const translatedPhrase = useTranslation('Hello, {name}', { name });
- If you're a translator, add a corresponding entry in language JSON files, for example:
{
"Hello world!": "Hallo Welt!"
}
If a corresponding entry in language file for current locale is not found, default locale will be used.
