Creating a Simple Angular App
Angular for Java Developers, Part 1
Matt Greencroft
  • Course duration: 2h 48m
Fullstack developers often earn higher salaries and have more career opportunities than developers who only specialize in front- or backends. Angular for Java Developers: Part One expands your Java skills by teaching you to build reactive, responsive, functional frontends using the Angular framework. You don’t need any existing knowledge of Angular or JavaScript—everything required to start building stunning frontends is covered in the course. By referencing Java and Java web technology examples, this course makes it quick and easy for Java developers to upgrade their skills to Angular. In the first in a running series of five videos, you’ll learn what Angular is, how to install Angular and set up a development environment, and how to build your first simple application.

About the subject

The Angular framework is used by millions of developers, powering frontends from simple prototypes to Google’s own web apps. Prized for its scalability, Angular also offers lightning fast speed and response times and the chance to reuse code for both web and mobile. Best of all, it can be integrated with backends built in Java.

About the video

Angular for Java Developers is a five-part course that teaches Java programmers how to use Angular and JavaScript to build applications that are maintainable, testable, and secure. In Part One, you’ll get to grips with how Angular works, what an Angular application looks like, and get started by creating your first simple Angular app. The video lays the groundwork for the case study example app you’ll build throughout all five videos, the architecture of Angular applications, as well as creating your own custom components.
