Components-based architecture is the preferred architecture for building Angular applications. However, there are certain limitations to consider when compared to a module-based architecture:
1. Complexity: As the number of components grows, it can become more difficult to manage and maintain the application. This can lead to increased complexity and make it harder to understand the structure and behavior of the application.
2. Reusability: Components are designed to be reusable, but as the application grows, it can become difficult to reuse components across different parts of the application.
3. Testability: Components can be unit tested, but as the number of components grows, it can become more challenging to test the application as a whole.
4. Performance: Components can sometimes result in poor performance because of the overhead involved in managing the component tree and the change detection mechanism.
A module-based architecture can help mitigate some of these limitations by grouping related components and services into modules, making the application more maintainable and easier to understand.
However, it's important to note that Angular has several features, such as lazy loading and ahead-of-time (AOT) compilation, which can help mitigate these limitations and improve performance in a components-based architecture.
Ultimately, the choice between a components-based or a module-based architecture will depend on the specific requirements and constraints of the application. Both architectures have their strengths and weaknesses, and the best choice will depend on the needs of the application and the experience of the development team.
