Mastering Angular Components

By: Kunz

Overview of this book

Mastering Angular Components will help you learn how to invent, build, and manage shared and reusable components for your web projects. Angular components are an integral part of any Angular app and are responsible for performing specific tasks in controlling the user interface. Complete with detailed explanations of essential concepts and practical examples, the book begins by helping you build basic layout components, along with developing a fully functional task-management application using Angular. You’ll then learn how to create layout components and build clean data and state architecture for your application. The book will even help you understand component-based routing and create components that render Scalable Vector Graphics (SVG). Toward the concluding chapters, you’ll be able to visualize data using the third-party library Chartist and create a plugin architecture using Angular components. By the end of this book, you will have mastered the component-based architecture in Angular and have the skills you need to build modern and clean user interfaces.

It's a good idea to mock out that component when you want to perform tests on the efforts component. The duration component itself relies on the rather complex editor component.
  • Efforts Timeline: As it is a purely graphical component to represent our task...
