Translating Properties of Objects in Angular Data Tables

When building applications with Angular, you may face various challenges, especially when trying to internationalize your app's content. One common challenge is translating the properties of an object that populates a data table. In this guide, we'll delve into this problem and provide you with a detailed solution using the ngx-translate library.

Understanding the Problem

Imagine that you have a data table displaying user information, such as first names and last names, stored in an object. When translating your app, you want to ensure that the table displays the translations of these labels instead of their default key names. For instance:

You want to represent prenom as "surname" and nom as "name" when displaying their values in the table. To achieve this, you might be using a JSON file for translations, like this:

The central question is: How can you translate the keys of your object so that they display the proper translations in the data table?

Solution Overview

To translate the properties of an object in your data table, you will utilize the ngx-translate library alongside Angular's *ngFor directive. The code snippet below demonstrates how this can be accomplished effectively:

Step-by-Step Guide

Set Up Translation Tag in Your Template:

Update your HTML template to include the translation pipe in the *ngFor loop. This will allow you to concatenate the translation keys dynamically.

In this code, "PROPERTIES." + i.key dynamically constructs the translation key. The translate pipe then looks for the corresponding keys defined in your translation JSON file.

Using the Translation JSON File:

Make sure your translation object is correctly set up. For example, your JSON file should contain:

Display in Your Data Table:

Now, when you run your application with the above implementation, it will successfully translate prenom and nom as defined in your translation JSON file, displaying "surname" and "name" respectively in the data table.

Conclusion

By following the steps outlined in this guide, you've learned how to translate the properties of an object within an Angular data table using the ngx-translate library. This approach not only enhances the user experience by presenting localized content, but it also simplifies the process of managing translations in your application.
