Overview
This 5-day course is a complete guide to building scalable web applications using Google’s popular Angular framework, leveraging the power of TypeScript to build type-safe applications.
An overview of the framework is given and then each of the 8 building blocks (Modules, Components, Directives, Metadata, Templates, Services, Data Binding and Dependency Injection) are covered in deep dives including testing. RxJS observables are covered as both discrete JavaScript and how they are integrated into Angular. Template-Driven and Reactive forms implementation applications is compared and examined. Creating a single page application through the use of routing is also on the outline of the course which can be seen below.
Delivery is through instructor-led explanations and short follow-up exercises that allow learners to experiment with code. A practical agile-style project is included for learners to complete, either as a collaborative group or individually.
Prerequisites
It is essential you understand the face of contemporary web development to attend this course. We insist upon JavaScript experience equivalent to the skills covered in Programming with JavaScript (QAJAVSC) along with good HTML and CSS skills (as covered in QAHTMLCSS).
This course uses TypeScript for all code demonstrations and exercises and so it is essential that attendees have experience equivalent to the skills covered in Programming with TypeScript (QAPTS).

How do QA’s virtual classroom courses work?
Our virtual classroom courses allow you to access award-winning classroom training, without leaving your home or office. Our learning professionals are specially trained on how to interact with remote attendees and our remote labs ensure all participants can take part in hands-on exercises wherever they are.
We use the WebEx video conferencing platform by Cisco. Before you book, check that you meet the WebEx system requirements and run a test meeting (more details in the link below) to ensure the software is compatible with your firewall settings. If it doesn’t work, try adjusting your settings or contact your IT department about permitting the website.
