How to Pass Multiple Properties Using @ Inject(MAT_DIALOG_DATA) in Angular Dialogs

When working with Angular Material dialogs, you may encounter scenarios where you need to share multiple pieces of data with a dialog component. This can be particularly challenging if you're trying to pass different data types or structures simultaneously. In this post, we will explore how to effectively pass multiple properties using the Angular Material dialog and ensure that your code remains clean and organized.

The Challenge

The common issue arises when one attempts to inject multiple parameters into a dialog component using @ Inject(MAT_DIALOG_DATA). Many developers find themselves in a situation similar to the one below:

Here, the developer is attempting to inject two separate data types: data1 as an array of ImportType, and data2 as an array of strings. However, the second property often ends up being identical to the first, leading to confusion and malfunction in the application.

The Solution

Instead of trying to inject multiple MAT_DIALOG_DATA, the recommended solution is to encapsulate your data into a single object. By doing so, you can maintain clarity and organization within your dialog component. Here’s how to achieve this:

Step 1: Define an Interface for Your Data

First, you’ll want to create an interface that represents the structure of the data you intend to pass to the dialog.

Step 2: Modify the Dialog Constructor

Next, modify the dialog's constructor to inject the encapsulated data object instead of separate variables.

This way, you are importing a single object that houses both the arrays you need for your dialog logic.

Step 3: Adjust the Dialog Configuration

Modify your dialog configuration to accommodate the new structure of the data set.

Step 4: Open the Dialog with the Encapsulated Data

Finally, update the method responsible for opening the dialog to make use of the new data structure.

Conclusion

By encapsulating the data in a single object, you simplify the process of passing various properties to an Angular Material dialog. This approach not only makes your code cleaner and easier to understand, but it also helps prevent issues associated with multiple injections of MAT_DIALOG_DATA. The next time you implement a dialog, remember this method to bolster your application's reliability and maintainability.

Whether you're dealing with simple data transfers or more complex interactions, adopting this encapsulation strategy will make your dialog components more robust and your codebase easier to manage. Happy coding!
