How to Dynamically Change the Font Weight of Selected Languages in React.js

When creating a multilingual interface in React, especially with libraries like i18next, you may want to enhance user experience by visually distinguishing the selected language. One common approach is to adjust the font weight of the language selector buttons based on which language is currently active. If you’re unsure how to implement this feature, you’re in the right place! In this guide, we’ll cover a straightforward method to change the font weight of the selected language using React and i18next.

The Problem: Changing Font Weight for Selected Language

You’ve set up language buttons using the i18next library, allowing users to switch between different languages. However, you’d like to make the active language more noticeable by changing its font weight. You may have tried some methods; perhaps you utilized conditional styling but didn't achieve the desired outcome. Don’t worry, we’ll guide you through how to implement this functionality effectively.

The Solution: Conditional Styling in React

To successfully change the font weight based on the selected language, follow these steps:

Step 1: Get Current Language

First, you need to retrieve the current language being used. i18next offers a simple way to access the active language. You can grab it as follows:

Step 2: Styling the Buttons

Now that you have the current language, you can apply conditional styling to your buttons. This involves checking the active language and setting the font weight accordingly.

Button Implementation

Here’s how you can apply it to your buttons:

Explaining the Code

handleClick Function: This function changes the language when a button is clicked, leveraging the i18n.changeLanguage(lang) method.

Conditional Style: The style property checks if the current language matches the language of the button (e.g., "en" or "de").

If it matches, the fontWeight is set to 800 (bold).

If it does not match, it defaults to 400 (normal weight).

Complete Example

Bringing it all together, here’s your complete component setup:

Conclusion

By dynamically changing the font weight of your language selector buttons, you can vastly improve the clarity and usability of your multilingual interface. Following the steps outlined above will allow users to easily recognize which language they have selected, enhancing their interaction with your application.

Feel free to experiment with different styles beyond just font weight – colors, backgrounds, or even animations can further add to your UI’s effectiveness. Happy coding!
