Dynamically Compile Angular Components in Angular 11: A Step-by-Step Guide

Angular is a powerful framework for building dynamic web applications, yet developers often encounter challenges when upgrading to new versions. One such issue arises from Angular's JIT (Just-In-Time) compilation, particularly when transitioning from Angular 8.2 to Angular 11. In this guide, we'll explore a recommended solution for dynamically compiling Angular components, allowing you to seamlessly display dynamic content in your applications.

Understanding the Problem

Upon upgrading to Angular 11, many developers face the following error:

[[See Video to Reveal this Text or Code Snippet]]

This error often occurs due to changes in the Angular Ivy compiler and the JIT compilation process. The system suggests switching to AOT (Ahead-of-Time) compilation for production use cases, but what if you still need to work with dynamically generated components?

The key to overcoming this challenge lies in understanding how to properly configure the Angular compiler and adjust your component and module structures.

The Solution

To resolve the JIT compilation errors while dynamically compiling components in Angular 11, follow these steps:

Step 1: Provide JIT Compiler Factory

In your RenderModule, you need to explicitly provide the JitCompilerFactory. This adjustment ensures that the Angular compiler is correctly loaded for your dynamic components.

Here’s how to implement it:

Step 2: Replace Component and Module Annotations

The next step involves changing the way you define dynamically created components and modules. Instead of using annotations, define them using functions. This modification helps avoid errors related to dynamic compilation.

Conclusion

By following these steps to configure the JIT compiler and refine your component/module definitions, you can successfully address the dynamic compilation issue in Angular 11. It’s always crucial to keep up with framework updates and be ready to adapt your code to new changes.

Now you're equipped to handle dynamic component generation in Angular 11 with confidence, ensuring your applications remain robust and dynamic.
