Streamlining Translation Management in NX Workspaces

Managing multilingual support across multiple applications can be quite challenging, especially when each application has its own set of translation files. Developers using ngx-translate in an NX workspace often find themselves duplicating effort by maintaining similar JSON translation files across different applications. If a small change is made in the translations, it can lead to multiple files being modified, which is both time-consuming and error-prone. In this guide, we will explore an effective strategy to share translation files across multiple Angular applications within an NX workspace, resulting in easier maintenance and consistency.

The Challenge

Imagine you have several Angular applications that share a common set of translations. Currently, you might have two JSON files (one for English and one for German) for each application. This setup can lead to:

Redundant Work: Every time a translation needs updating, multiple files require changes.

Consistency Issues: There's a risk of having discrepancies between translation files across applications.

To alleviate these challenges, the goal is to move the common translations into a centralized library while maintaining application-specific translations in each app.

Solution Overview

The solution involves creating a library in your NX workspace where you can store shared translation files. Here’s how you can set it up step-by-step:

1. Create the Translation Files in the Library

Begin by creating a new library in your NX workspace that will house the shared translation files. Place your translation JSON files (e.g., ENG.json and DE.json) in a directory like assets/i18n within the library directory.

2. Update the Project Configuration

Next, tell the applications about these shared assets. To do this, open the project.json file of each application that needs access to the translations and add the following code under the build.options.assets section:

This configuration ensures that the translation files in the library are bundled with the application.

3. Load the Translation Files

Now, you need to configure the application to load the shared translation files. In your app.module.ts, you can use the MultiTranslateHttpLoader to load multiple translation sources. Add the following code:

Important Considerations

File Load Order: It is crucial to note the order in which the translation files are loaded. If both files contain the same key, the key from the second file will overwrite the key from the first one. Thus, ensure that the shared translations are loaded before any application-specific translations.

Conclusion

By centralizing common translation files into a library, you've made it significantly easier to manage translations across multiple applications in your NX workspace. This approach not only reduces redundancy but also enhances the consistency of translations among similar applications. While this method may not be the only solution, it has proven effective for many developers looking to streamline their multilingual support using ngx-translate.

With these simple steps, you are now well on your way to achieving a more maintainable and efficient translation management system within your Angular applications. Happy coding!
