How to Use react-i18next for Dynamic Translations in React Applications

In the world of web development, providing a seamless multilingual user experience is essential. For developers using React, react-i18next is a powerful tool that simplifies the process of adding translations to your applications. One common challenge arises when you want to translate strings that are nested within objects or lists. In this guide, we will explore how to use react-i18next to manage translations effectively, especially when dealing with dynamic components like menus.

The Problem

You have a JavaScript object called myInformation, which contains various keys and nested items, including those you wish to translate. However, when you try to implement the useTranslation hook, you encounter difficulties translating these items especially when they are being mapped over. Specifically, the goal is to ensure that all dynamic text is presented in the user's selected language without breaking the component logic.

Here is a snippet of how myInformation looks:

The Solution

To resolve this issue, we can strategically use the useTranslation hook within the appropriate component. Here's how to implement this step-by-step.

Step 1: Set Translation Keys

Firstly, update your myInformation object so that the strings can be recognized as translation keys. Instead of using plain text for the titles, use unique identifiers that will serve as keys for translation.

Step 2: Implement useTranslation in the Parent Component

In the main component, where you're rendering your myInformation object, make sure to import useTranslation and call it.

Step 3: Use useTranslation in the Sub-Component

Next, you need to ensure that the OneMenuItem component also utilizes the useTranslation hook to convert the translation keys into their respective localizations during rendering.

Conclusion

By following the steps above, you can effectively leverage react-i18next to manage dynamic translations in your React application. With useTranslation, you can turn static text into multi-language support while maintaining clean and organized code. Now your application can effortlessly adapt to a global audience, enhancing the user experience remarkably.

Remember: The key takeaway is to treat strings in your objects as translation keys, and call t() to access the translations where necessary.

Implement these steps and make your application more accessible to users worldwide!
