Dynamically Load Components in Angular 13 from a JSON File

In modern web development, the ability to load components dynamically can greatly enhance the efficiency and flexibility of your applications. If you're using Angular 13 and want to load a list of components based on names specified in a JSON file, you're in the right place! This guide will walk you through the process step by step.

Explanation of the Code

ng-container: This is a logical container that Angular uses to group elements without adding extra nodes to the DOM.

*ngFor: It’s a structural directive that allows you to iterate over a collection (in this case, componentListToLoad).

Step 3: Final Output

Once you implement the above steps, your application will dynamically render "Component1" and "Component2" in the template when it's run. Any additional components can be added to the JSON array, and they will be rendered without further code changes in your HTML template.

Conclusion

By following the steps outlined above, you can easily load components dynamically in Angular 13 using a JSON file. This approach not only reduces the need for hardcoding but also allows for easier management of component configurations, making your application more modular and flexible.

Now that you know how to load components dynamically, consider other ways to enhance your Angular application using external configurations. Happy coding!
