Leveraging react-i18next for Internationalization Outside React Components

Internationalization (i18n) can be a tricky aspect to handle in web applications, especially when you want to access translation functions outside of React components. If you’ve ever faced difficulties using the t() function from react-i18next in a standalone JavaScript or TypeScript file, you're not alone.

In this guide, we’ll explore the problem of using the t() function in an isolated context and provide a clear, step-by-step solution to resolve it.

The Problem: Using t() Outside of Components

Here’s a common scenario: You have a constants file that exports data, and you want to include localized strings using the t() function. However, you might find that calling t('key') only returns the key itself rather than the translated string.

Example Code Snippet:

In the snippet above, the expected translations don’t appear correctly. Instead, you see just the keys displayed.

The Solution: Configuring i18next Correctly

After troubleshooting, I found a solution that worked efficiently for my setup. The core issue was using the i18next backend module, which wasn’t necessary for my use case.

Step 1: Modify i18n Configuration

First, update your i18n.js (or .ts) configuration file. By removing the backend module and defining translations directly within your configuration, you will ensure that the t() function works as intended.

Step 2: Using t() in Your Data Files

To utilize the t() function in your constant data files, ensure you import your i18n configuration correctly. With this setup, you can access the translated strings.

Important Note: Language Change Handling

If you want your data to update automatically when the language changes (e.g., clicking a button to switch languages), you need to listen for language change events. The example above shows how to do this by updating the appropriate fields in your array.

Conclusion

Utilizing the t() function from react-i18next in files outside of your React components enhances the flexibility and consistency of code across your application. By adjusting the configuration as shown, you can ensure that your translations are correctly loaded and utilized.
