React Intl Tools
A package that provides components to simplify working with react-intl
.
Add internationalization and localization capabilities to your React app in 4 simple steps:
- Wrap your main app with the
react-intl-tools
'<LocaleContextProvider>
- Use
react-intl
's APIs (formatMessage()
,<FormattedMessage />
, etc) as you would normally - Extract and compile your messages with
formatjs
'extract
andcompile
methods - Call
react-intl-tools
'setLocale()
method to update the language

Installation
npm install react-intl-tools
Setup and usage
react-intl-tools
comes with two main utilities:
LocaleContextProvider
is simply a wrapper around<ReactIntl.Provider>
component. It takes two props:defaultLocale
a string that specifies the default locale to usetranslations
an object that contains the available translations
LocaleContext
provides alocale
string andsetLocale(activeLocale)
method for working with the active (currently selected) locale.
Using react-intl-tools
is as simple as:
- Wrapping your main app with the
LocaleContextProvider
and - Calling the
setLocale()
method returned byLocaleContext
to update (or switch) the locale.
Example setup
// File: app.js
import React from "react"
import { LocaleContext } from "react-intl-tools"
function App() {
const { setLocale } = React.useContext(LocaleContext);
return (
<div>
<nav>
<select value="en" onChange={(e) => setLocale(e.target.value)}>
<option value="">Select Language</option>
<option value="en">English</option>
<option value="fr">French</option>
<option value="de">German</option>
</select>
</nav>
// Rest of app code goes here
</div>
)
}
// File: index.js
import ReactDOM from "react-dom"
import { LocaleContextProvider } from "react-intl-tools"
import App from "./app";
import en from "path/to/translations/en.json"
import fr from "path/to/translations/fr.json"
import de from "path/to/translations/de.json"
const translations = {
en,
fr,
de,
}
ReactDOM.render(
<LocaleContextProvider defaultLocale="en", translations={translations}>
<App />
</LocaleContextProvider>,
document.getElementById("root")
)
Using the built-in LocaleSelector
react-intl-tools
also comes with a <LocaleSelector>
dropdown component
that you can use in lieu of implementing your own locale switching mechanism.
If your locale switcher is going to be a dropdown (that is, a <select>
element),
you can use the LocaleSelector
component instead.
Let's re-write our app.js
file from the previous example to use the LocaleSelector
component.
// File: app.js
import React from "react"
import { LocaleSelector } from "react-intl-tools"
const supportedLanguages = [
{ code: "en", name: "English" },
{ code: "fr", name: "French" },
{ code: "de", name: "German" },
];
function App() {
return (
<div>
<nav>
<LocaleSelector languages={supportedLanguages} selectorText="Choose language" />
</nav>
// Rest of app code goes here
</div>
)
}
