The Angular provides a consistent set of patterns. for creating components, templates, modules, and services helping you come up to speed quickly. after that, you’ll understand how to build components, create the user interface for your application in a template. and power it up with data binding and directives.
It discovers how to build services for logic needed across components and inject those services where they need. and step by step understands how to send requests to a web server using HTTP and observables. and also see how to set up routing to navigate between the views of your application. In addition, you’ll see how to use the Angular command line interface or CLI to generate, execute, test, and deploy your Angular application.
Whether you are new to Angular or migrating from AngularJS, you want to come up to speed quickly. with Angular’s components, templates, services. and also provides the basics you need to get started building an Angular application. the step by step
you will understand, what is a component? Where do we put the HTML for our user interface? When should we use data binding? Why do we need a service? And How do we build an Angular application?
Why did we need a new Angular?
Structure of an Angular Application
In Angular, an application
So, what is an Angular component? Each component comprise of a template which is the HTML for the user interface fragment defining a view for the application. include to that a class for the code associated with the view. The class contains the properties or data elements available for use in the view and methods. which perform actions for the view such as responding to a button click. the component also has metadata, which provides more information about the component to Angular. the metadata identifies the class as an Angular component.
So, a component is a view defined with a template. it’s associated code defined with a class, and more information, defined with metadata. The Angular modules help us organize our application into cohesive blocks of functionality. Every Angular application has at least one Angular module called the application’s root Angular module. An application can have any number of more Angular modules including feature modules. that merge the components for a specific application feature.
Basic knowledge of
2] HTML for building the user interface
3] Cascading style sheets or CSS for styling.
It is helpful if you have some exposure to object-oriented programming concepts. through coding with C++, C#, Java, or PHP, but if you don’t have any exposure to OOP, that’s okay. You do not need any prior knowledge or Angular or TypeScript.
