Overview of this book

<p>If you have been burnt by unreliable JavaScript frameworks before, you will be amazed by the maturity of the Angular platform. Angular enables you to build fast, efficient, and real-world web apps. In this Learning Path, you'll learn Angular and to deliver high-quality and production-grade Angular apps from design to deployment.</p> <p>You will begin by creating a simple fitness app, using the building blocks of Angular, and make your final app, Personal Trainer, by morphing the workout app into a full-fledged personal workout builder and runner with an advanced directive building - the most fundamental and powerful feature of Angular.</p> <p>You will learn the different ways of architecting Angular applications using RxJS, and some of the patterns that are involved in it. Later you’ll be introduced to the router-first architecture, a seven-step approach to designing and developing mid-to-large line-of-business apps, along with popular recipes. 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.</p> <p>This Learning Path includes content from the following Packt products:</p> <p><span style="background-color: transparent;">•Angular 6 by Example by Chandermani Arora, Kevin Hennessy&nbsp;</span><br /><span style="background-color: transparent;">•Architecting Angular Applications with Redux, RxJS, and NgRx by Christoffer Noring</span><br /><span style="background-color: transparent;">•Angular 6 for Enterprise-Ready Web Applications by Doguhan Uluca</span></p>

Chapter 9. Create a Local Weather Web Application

We will be designing and building a simple Local Weather app with Angular and a third-party web API, using an iterative development methodology. You will focus on delivering value first while learning about the nuances and optimal ways of using Angular, TypeScript, Visual Studio Code, Reactive Programming, and RxJS. 

In this chapter, you will learn the following:

  • Planning out your roadmap using Waffle as a GitHub-connected Kanban board
  • Crafting a new UI element to display current weather information using components and interfaces
  • Using Angular Services and HttpClient to retrieve data from OpenWeatherMap APIs
  • Leveraging observable streams to transform data using RxJS

The code samples provided in this book require Angular version 5 and 6. Angular 5 code is runtime compatible with Angular 6. Angular 6 will be supported in LTS until October 2019. The most up-to-date versions of the code repositories may be found at the following:
