// Before React 18
import React from 'react';
import ReactDOM from 'react-dom';
const App = () => {
return <h1>Hello, World!</h1>;
};
ReactDOM.render(<App />, document.getElementById('root'));
// After React 18
import React from 'react';
import { render } from 'react-dom';
const App = () => {
return <h1>Hello, World!</h1>;
};
render(<App />, document.getElementById('root'));
Conclusion: With the deprecation of ReactDOM.render in React 18, it’s essential to understand the new rendering model and migrate your code accordingly. By embracing the latest features and optimizations offered by React 18, you can unlock enhanced performance and deliver a superior user experience. Follow the steps outlined in this blog post, and you’ll be well on your way to upgrading your React applications successfully.
Here, we two files to support two locales. And it has been stored in xlf format.
XLF is an XML localization file format.
Running application
ng serve
The above picture shows the default text from the application.
Now let’s run the custom command to point it to french language and see the output.
ng serve –configuration=fr
Therefore the word angular-localise is changed into Bonjour based on the language we have configured.
In conclusion, we can configure N number of languages and host it based on needs.

Finally, Few things need to be done while experimenting with the above code.
Since this package is supported in angular 9 we need to maintain a matching node environment to experiment with the code. And you can find the entire source code in this GitHub Repository.
