Interpolating Strings in React i18n Without <Trans>

In today's globalized world, providing multi-language support in your applications is essential. For React developers using the i18n library, there’s often a need to dynamically interpolate variables into translation strings. This is particularly useful when you want to create user-friendly alerts or notifications that include variable content, all without relying on the <Trans> component. In this guide, we’ll dive into how to accomplish this using the i18n service directly.

The Problem

Let's say you have a React component with a function designed to alert users when a certain value needs to be met. For instance, the function might look like this:

Now, you want to replace the hardcoded string within the alert with a translatable message that retrieves the percentage dynamically from your translation JSON. Here’s what your translation JSON might look like:

The challenge is to seamlessly include the variable n into your translation string without using the <Trans> component. So, how can we achieve this?

The Solution

To interpolate string values in your translations, you can leverage the i18n service provided by the i18next library. The solution is straightforward and can be implemented in a few simple steps.

Step 1: Import the i18n Library

Ensure that you have the i18next library installed in your project. Once installed, you need to import it at the beginning of your React component file:

Step 2: Use the i18n Service in Your Function

You can directly call the t function provided by the i18n service to translate messages. Here is how to modify your existing function:

Important Note

Before calling this function, make sure that the i18n library has been initialized. You should invoke i18n.init() somewhere in your application, typically during the setup phase.

Full Example

Below is a complete example that encapsulates the above steps. This example assumes you have already initialized i18n with the correct language setup and translation resources:

Conclusion

Interpolating variables in translation strings without using the <Trans> component in React i18next is a straightforward task. By utilizing the i18n service, you can seamlessly create dynamic, user-friendly messages that enhance the overall user experience of your application. This method not only promotes localization but also keeps your code clean and manageable.

Make your application accessible to a wider audience by integrating multilingual support efficiently and effectively. Happy coding!
