Angular 6 for Enterprise-Ready Web Applications

By: Doguhan Uluca

Overview of this book

Angular 6 for Enterprise-Ready Web Applications follows a hands-on and minimalist approach demonstrating how to design and architect high quality apps. The first part of the book is about mastering the Angular platform using foundational technologies. You will use the Kanban method to focus on value delivery, communicate design ideas with mock-up tools and build great looking apps with Angular Material. You will become comfortable using CLI tools, understand reactive programming with RxJS, and deploy to the cloud using Docker. The second part of the book will introduce you to the router-first architecture, a seven-step approach to designing and developing mid-to-large line-of-business applications, along with popular recipes. You will learn how to design a solid authentication and authorization experience; explore unit testing, early integration with backend APIs using Swagger and continuous integration using CircleCI. In the concluding chapters, you will provision a highly available cloud infrastructure on AWS and then use Google Analytics to capture user behavior. By the end of this book, you will be familiar with the scope of web development using Angular, Swagger, and Docker, learning patterns and practices to be successful as an individual developer on the web or as a team in the Enterprise.

Using Angular Services and HttpClient to retrieve data

Now you need to connect your CurrentWeather component to the OpenWeatherMap APIs. In the upcoming sections, we will go over the following steps to accomplish this goal:

  1. Create a new Angular Service
  2. Import HttpClientModule and inject it into the service
  3. Discover the OpenWeatherMap API

  1. Create a new interface that conforms to the shape of the API
  2. Write a get request
  3. Inject the new service into the CurrentWeather component
  4. Call the service from the init function of the CurrentWeather component
  5. Finally, map the API data to the local ICurrentWeather type using RxJS functions so that it can be consumed by your component
