Our Comprehensive Angular 4 training covers all major topics required to fully use the Angular framework. Angular 4 makes the creation of single page applications even easier than before. In this 5-day course developers will learn to use Angular Directives, create Angular Components and Services to develop applications based on the Model-View-Controller (MVC) architecture. You will also learn to use HTML templates to define views and to connect views with code using output, two way, event and property bindings. The course reviews the benefits and challenges of Single Page Applications and how to overcome those challenges using the Angular Router. The course will also cover everything you need to know about Typescript – a programming language based on JavaScript that is used to create Angular 4 Applications. In addition to the basics of using the Angular 4 framework, you will also learn advanced topics not covered in our 3 day Introduction to Angular 4 programming class. This will include specifics about how to consume REST web services and WebSocket data from Angular 4 applications. Advanced use of the Angular Routing module and Angular Animations are covered. Developers will learn how to develop Angular 4 applications using AngularCLI. Details of how to test and debug Angular 4 applications are covered in addition to best practices for the style and organisation of Angular 4 projects. Lab exercises provide essential and practical hands-on experience for each topic.
