I'm trying to figure out how to change language using React-Intl. This is my first React App and it has been made with create-react-app, I'm not using Redux nor Flux.
In my index.js I have the following code:
import React from 'react';
import ReactDOM from 'react-dom';
import TodoApp from './components/TodoApp';
import registerServiceWorker from './registerServiceWorker';
import './index.css';
// Bootstrap CSS libraries
import 'bootstrap/dist/css/bootstrap.css';
import 'bootstrap/dist/css/bootstrap-theme.css';
import { IntlProvider, addLocaleData } from 'react-intl';
import intlEN from 'react-intl/locale-data/en';
import intlES from 'react-intl/locale-data/es';
import intlMessagesES from './i18n/locales/es.json';
import intlMessagesEN from './i18n/locales/en.json';
addLocaleData([...intlEN, ...intlES]);
/* Define your translations */
let i18nConfig = {
locale: 'es',
messages: intlMessagesES
};
let changeLanguage = (lang) => {
i18nConfig = { locale: lang, messages: intlMessagesEN };
return i18nConfig;
}
ReactDOM.render(
<IntlProvider locale={ i18nConfig.locale } key={ i18nConfig.locale } messages={ i18nConfig.messages }>
<TodoApp onChangeLanguage={changeLanguage} />
</IntlProvider>,
document.getElementById('root'));
registerServiceWorker();
TodoApp is sending a string on 'lang' parameter by props (i.e.: 'es' or 'en'), when I change i18nConfig nothing seems to change with IntlProvider. My thought was that change my i18nConfig variable then all my app would change language as well.
I have FormattedMessages in TodoApp and my two JSON messages are filled like this:
// i18n/locales/en.json
{
"footer.add.placeholder": "Enter a name ...",
"footer.add.priority0.text": "No priority",
"footer.add.priority1.text": "Priority 1",
...
}
Do you know what am I missing on my code ?? Maybe I have not understand something right about React-Intl. Any advice will be helpful, thank you.
