Then you would just have to implement logic removal on the server side. You can implement it with Javascript and invoke a command with those removed todos' index as a parameter to avoid re-rendering the whole list. The potential problem might be the re-rendering performance when the number of items is very large. Therefore, if it's critical to have a fast response time for your application, you can choose a client-side implementation. Meanwhile, the server-side implementation will increase the network traffic and requires more execution time (at least a round-trip from a client to server). If a page is accidentally closed or reloaded, the data that have not been synchronized with a server will be lost.For a complicated business logic, Java has better compiler checking.Avoid exposing business logic to users.To implement such functions on the client-side, you would have to push all the data to the client-side first. This article is part of my personal wiki where I write personal notes while I am learning new technologies. An application logic might involve a lot of data from different parts of a system it is, therefore, easier to access them on the server-side.In general, we recommend implementing on the server-side, the reasons are: Todo įor each function like add or archive todo, you need to determine whether to implement it on the client or server-side. Although a purely client-side application is working, it still doesn't synchronize its data to the server-side. Please run the project with an application server that supports servlet 3 like Tomcat 7 or Jetty 8.įor easy understanding, we build the UI mainly with ZK native components and replace some of them with zul components if necessary therefore, you can just copy the HTML including CSS and Javascript from AngularJS's website. Since servlet 3 is easier to expose the web static resources, we specify our web.xml with servlet 3. When I include Bootstrap, maven will also include Jquery web JAR for the transitive dependency. It lets you explicitly and easily manage the client-side dependencies with Maven, and it also supports other dependency management tools like ivy or Gradle. In this example project, we rely on WebJars to include 3rd party front-end resources like AngularJS and Bootstrap theme. The overall concept of the communication between AngularJS and ViewModel is: One is to invoke a command method, and another is to register a callback function to be invoked after a ViewModel executes a command method. It mainly provides 2 methods to communicate with a ViewModel. This channel can simplify the complexity to integrate a 3rd party JavaScript library and widget with ZK. The API provides a server-client communication channel so that you can easily communicate with ZK’s ViewModel without knowing AJAX details. This article will talk about how to integrate AngularJS in a simple way with ZK 8's new feature, client-side binding API. I assume the readers had read its tutorial, so I won't introduce AngularJS in detail here. Or you might want to integrate an existing AngularJS widget with ZK. You could build a custom view with it when there is no suitable ZK component available. Is a well-known client-side UI framework, and its two-way data binding on HTML is the most notable feature.
