How to Change the Displayed Value in an ngx-translate Language Select Dropdown

When developing applications using Angular and internationalization libraries like ngx-translate, you might notice that the language dropdown displays short language codes (like "en", "es", and "fr"), which can be less user-friendly. Instead, you might want to display full language names such as "English", "Espanol", and "Francais". If you've been struggling with this aspect, you are not alone! In this guide, we'll walk you through a clear solution that allows you to customize the displayed values in your language select dropdown effectively.

Understanding the Problem

ngx-translate is a powerful library that allows you to manage translations in your Angular application. However, by default, it focuses purely on the language codes and doesn't directly support displaying friendly names in dropdowns. This limitation can affect the user experience, especially in multilingual applications. Luckily, you can easily implement a workaround to achieve your desired outcome.

Step-by-Step Solution

1. Create a Supported Languages Constant

First, we need a way to define the languages we want to support, along with their corresponding codes and friendly names. We can do this by creating a constant in a separate file. Follow these steps:

Create a new file called supported-languages.ts in your project.

Add the following code to define the supported languages:

2. Update Your Language Selector Component

Next, you’ll need to import this constant into your component where the language dropdown will be rendered. Here’s how to do it:

Open your language selector component file (e.g., language-selector.component.ts).

Import the SUPPORTED_LANGUAGES constant and set it to a class property.

3. Modify the HTML to Display Friendly Names

Now, let’s update the HTML template of your language selector to display the friendly names instead of the codes. Replace the existing dropdown code with the following:

This way, the dropdown will now show "English", "Espanol", and "Francais" while keeping the underlying values based on their language codes.

4. Update Your App Component

Finally, you’ll also need to ensure that your application recognizes the supported languages when initializing ngx-translate. Open your main application component file (e.g., app.component.ts) and modify it as follows:

This ensures that ngx-translate knows about the language codes you’ll be working with.

Conclusion

By following these steps, you have successfully customized the displayed values in your ngx-translate language select dropdown. This method not only enhances user experience by providing clear language options but also keeps your implementation organized and easy to manage.

Feel free to expand the SUPPORTED_LANGUAGES constant if you wish to add more languages in the future. With this strategy, handling multiple languages becomes much simpler and more maintainable. Happy coding!
