Conventionally, each view has an associated controller; for example, if the application had a client view, it would typically have an associated Clients controller as well. However, developers are free to make other kinds of controllers if they wish. [35] Django calls the object playing this role a "view" instead of a controller. [30]
Angular (also referred to as Angular 2+) [4] is a TypeScript-based free and open-source single-page web application framework. It is developed by Google and by a community of individuals and corporations. Angular is a complete rewrite from the same team that built AngularJS.
These frameworks use actions that do the required processing, and then "push" the data to the view layer to render the results. [5] An alternative to this is pull-based architecture, sometimes also called "component-based". These frameworks start with the view layer, which can then "pull" results from multiple controllers as needed.
AngularJS's templating is based on bidirectional UI data binding. Data-binding is an automatic way of updating the view whenever the model changes, as well as updating the model whenever the view changes. The HTML template is compiled in the browser. The compilation step creates pure HTML, which the browser re-renders into the live view.
Fresh focuses on server-side rendering with zero runtime overhead. Enhance.dev prioritizes progressive enhancement patterns using Web Components. While these tools reduce reliance on client-side JavaScript by shifting logic to build-time or server-side execution, they still use JavaScript where necessary for interactivity.
With server-side rendering, static HTML can be sent from the server to the client, and client-side JavaScript then makes the web page dynamic by attaching event handlers to the HTML elements in a process called hydration. Examples of frameworks that support server-side rendering are Next.js, Nuxt.js, Angular, and React.
To render a document such as a HTML page, most web browsers use an internal model similar to the DOM. The nodes of every document are organized in a tree structure, called the DOM tree, with the topmost node named as "Document object". When an HTML page is rendered in browsers, the browser downloads the HTML into local memory and automatically ...
The view engines used in the ASP.NET MVC 3 and MVC 4 frameworks are Razor and the Web Forms. [ 29 ] [ 30 ] Both view engines are part of the MVC 3 framework. By default, the view engine in the MVC framework uses Razor .cshtml and .vbhtml , or Web Forms .aspx pages to design the layout of the user interface pages onto which the data is composed.
