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>

Personal Trainer and server integration


As described in the previous section, client-server interaction is all about asynchronicity. As we alter our Personal Trainer app to load data from the server, this pattern becomes self-evident.

In the previous chapter, the initial set of workouts and exercises was hardcoded in the WorkoutService implementation. Let's see how to load this data from the server first.

Loading exercise and workout data

Earlier in this chapter, we seeded our database with a data form, the seed.js file. We now need to render this data in our views. The MongoLab Data API is going to help us here.

Note

The MongoLab Data API uses an API key to authenticate access requests. Every request made to the MongoLab endpoints needs to have a query string parameter, apikey=<key>, where key is the API key that we provisioned earlier in the chapter. Remember that the key is always provided to a user and associated with their account. Avoid sharing your API keys with others.

The API follows...
