Spring Boot and Angular

Overview of this book

Angular makes building applications with the web easy and Spring Boot helps get an application up and running using just a few lines of code and minimal configuration. This book provides insights into building full-stack apps using Angular and Spring Boot effectively to reduce overall development time and increase efficiency. You'll start by setting up your CI/CD pipeline and then build your web application’s backend guided by best practices. You'll then see how Spring Boot allows you to build applications faster and more efficiently by letting the Spring Framework and Spring Boot extension do the heavy lifting. The book demonstrates how to use Spring Data JPA and add its dependencies along with Postgres dependencies in the project to save or persist a user's data in a database for future use. As you advance, you'll see how to write tests and test a service using Mockito. Finally, you'll create a CI workflow or pipeline for a Spring Boot and Angular application to enable operations to deliver quality applications faster. By the end of this Spring Boot and Angular book, you'll be able to build a full-stack web application and deploy it through continuous integration and continuous deployment.

Basic form controls

This section will now discuss more of the concepts of form controls in reactive forms. We have already created an example of form controls in the previous section, but now, we will discover more about the functions and capabilities of form controls in Angular.

Form controls represent a single form element inside a form; they store the value of a form element that allows us to retrieve data of each input. This can be input, textarea, or any element that accepts values. When used in Angular, form controls can be instantiated by adding new FormControl('') code; we can see that it takes a single argument that defines the values of the control. These values can be null as form controls can be reset.

Form controls are like the properties of a JSON object, but compared to JSON, each control has its methods that will help us control, modify, and validate the values.

Next, let’s have a look at the different methods and features of form controls...
