Are there any risks in combining MVVM [angularjs, knockout.js] with MVC [JSF/spring]?

What are the benefits of combining MVVM models like AngularJS and Knockout.js with MVC frameworks like JSF or Spring?

  1. Is it considered best practice to manipulate MVVM objects and variables from within an JSF page? For example, updating a dropdown list in an AngularJS model using a JSF controller to fetch the list object. Is this method efficient, messy, or just a workaround?

Answer №1

I must admit that my knowledge of JSF and Knockout is limited. However, it seems likely that a clash may occur between a component-based framework like JSF or Wicket and Angular because both frameworks strive to take control over the displayed components. Here are some thoughts:

  • Is there really a need for a server-side component framework? Perhaps using a request-based framework such as Spring MVC or Struts would suffice since they handle page loading efficiently.
  • If you stick to one technology for each particular task, such as using JSF for page containers and Angular for content within the page, you might be able to make it work smoothly. It's important to consider that this approach may not fully utilize the benefits of JSF.

Answer №2

Currently, I am in the process of implementing this strategy. While I cannot definitively say what the best practice is, our team has determined that the ability to generate dynamic HTML output from the server is essential, even when utilizing an MVVM framework on the front end. Tasks such as internationalization are more effectively managed on the server side, and relying solely on static HTML from the server can present numerous limitations.

One major challenge we have encountered is complexity. With controllers, models, and views on the server working in conjunction with controllers, templates, and viewmodels on the client side, the architecture can become convoluted, especially for new team members. Therefore, thorough documentation and a well-structured code base are imperative.

Despite these challenges, I believe that this approach is valid. So far, we have not experienced any negative repercussions from it :)
