Overview of this book

Angular, loved by millions of web developers around the world, continues to be one of the top JavaScript frameworks thanks to its regular updates and new features that enable fast, cross-platform, and secure frontend web development. With Angular, you can achieve high performance using the latest web techniques and extensive integration with web tools and integrated development environments (IDEs). Updated to Angular 10, this third edition of the Learning Angular book covers new features and modern web development practices to address the current frontend web development landscape. If you are new to Angular, this book will give you a comprehensive introduction to help you get you up and running in no time. You'll learn how to develop apps by harnessing the power of the Angular command-line interface (CLI), write unit tests, style your apps by following the Material Design guidelines, and finally deploy them to a hosting provider. The book is especially useful for beginners to get to grips with the bare bones of the framework needed to start developing Angular apps. By the end of this book, you’ll not only be able to create Angular applications with TypeScript from scratch but also enhance your coding skills with best practices.

Data binding with template-driven forms

Template-driven forms are one of two different ways of integrating forms with Angular. It is an approach that is not widely embraced by the Angular community for the reasons described previously. Nevertheless, it can be powerful in cases where we want to create small and simple forms for our Angular app. Τemplate-driven forms can stand out when used with the ngModel directive to provide two-way data binding in our components.

We learned about data binding in Chapter 3, Component Interaction and Inter-Communication, and how we can use different types to read data from an HTML element or component and write data to it. In this case, binding is either one way or another, which is called one-way binding. We can combine both ways and create a two-way binding that can read and write data simultaneously. Template-driven forms provide the ngModel directive, which we can use in our components to get this behavior. We can add template-driven forms...
