If a change happens to this object, it’s updated in the view. The data on $scope object in the controller is bound to the template/view. With AngularJS 1.x, two-way data binding is a powerful feature. It may also have multiple child components providing their own view and functionality.įigure 2: Composition of components Unidirectional data flow See Figure 2 where each component has its own view. The framework is not seen as MV* framework anymore.Īn Angular application is now seen as composition of components. They allowed manipulating DOM.Īngular 2 application created a category of directives called Components, which allowed creating custom HTML elements and reusing them.Īngular 2 onwards, there is no explicit controller. Largely, AngularJS 1.x applications achieved it with Directive, which allowed creating custom HTML elements with AngularJS. One should be able to reuse these elements by adding it in the markup and providing state on the fly. Modern web applications required reusable components or custom HTML elements. Objects on $scope could be either Model or View-Model, depending on overall architecture including server-side.Įven though this is a proven architectural pattern and is the standard solution for an application with view, there are certain disadvantages.Templates can bind data on $scope from the controller. An object $scope is injected in the function. Controller is a function defined using the API.In an AngularJS application, that runs in a web browser, It is a good fit for all applications that have a view to present to the user.ĪngularJS’s MV* approach was to support any variations of these famous patterns. Be it web applications developed using Java, Microsoft ASP.NET or iOS apps using Objective C, they have all used an architectural pattern. The Model-View-Controller (MVC) and its variations Model-View-Presenter(MVP) and Model-View-View-Model(MVVM) frameworks have been used with applications for a very long time. This article does not intend to be a tutorial for all the features over time, rather it tries to summarize and provide a bucket list of enhancements over time.Īngular Evolution - v1.x to v6 AngularJS 1.x Context It attempts to look back at the original context of Angular application development and its progress. This article tries to summarize this evolution process. Subscribe to this magazine for FREE and receive all previous, current and upcoming editions, right in your Inbox.

This tutorial is from the DotNetCurry(DNC) Magazine with in-depth tutorials and best practices in JavaScript and. To keep up with these changes, Angular has evolved too. As browsers got better, new language features were added to JavaScript. It provided structure to the not so evolved JavaScript. Angular.js, one of the famous JavaScript frameworks for developing rich web applications using HTML5 and latest versions of JavaScript (ES5 and above), has evolved over time.Īngular started as a framework aimed to develop rich web applications, faster and better.
