Resolving the react-i18next Localization Issue: Displaying Translations Instead of Key Names

If you're working on a multi-language React project using react-i18next, you may encounter a frustrating issue: instead of showing the translated text, your application displays the key name itself in the DOM. In this guide, we'll explore this problem and provide a step-by-step solution to ensure your application translates text correctly according to the selected language.

The Localization Problem

Imagine you are building a React application that needs to support multiple languages. Upon rendering a component meant for localization, you see the following output in the browser:

Instead of the translated string, you're presented with the key name, which usually indicates that the translation files are not being loaded correctly.

The Setup

Your setup involves several components:

React and ReactDOM: the core libraries for creating the application

i18next: the internationalization library used for handling translations

LanguageDetector: for detecting and using user language preferences

HttpApi: for fetching translation files from the server

Your project's index.js includes the initialization settings for these libraries, and you have translation files structured as follows:

locales/ar/translation.json for Arabic translations

locales/tr/translation.json for Turkish translations

Identifying the Issue

In the index.js file, you have the following configuration for loading translation files:

This path seems incorrect as it prevents react-i18next from locating the translation files when rendering the application. If the files aren’t loaded, the key names will be displayed instead of the corresponding translated values.

The Solution

To rectify this issue, you need to correct the loadPath in the i18next configuration. Here’s what you should update it to:

Updated Configuration

Your updated index.js should look like this:

Result

After making the adjustments, when you render your component again, you should see the expected translation on the page:

Conclusion

Localization can sometimes present challenges, but with react-i18next, solutions often involve simple adjustments in configuration settings. By ensuring the correct load path for your translation files, you can effectively avoid the issue of key names displaying instead of their associated translations. Happy coding, and may your applications thrive in multiple languages!
