Overview of this book

The MEAN Stack is a framework for web application development using JavaScript-based technologies; MongoDB, Express, Angular, and Node.js. If you want to expand your understanding of using JavaScript to produce a fully functional standalone web application, including the web server, user interface, and database, then this book can help guide you through that transition. This book begins by configuring the frontend of the MEAN stack web application using the Angular JavaScript framework. We then implement common user interface enhancements before moving on to configuring the server layer of our MEAN stack web application using Express for our backend APIs. You will learn to configure the database layer of your MEAN stack web application using MongoDB and the Mongoose framework, including modeling relationships between documents. You will explore advanced topics such as optimizing your web application using WebPack as well as the use of automated testing with the Mocha and Chai frameworks. By the end of the book, you should have acquired a level of proficiency that allows you to confidently build a full production-ready and scalable MEAN stack application.

Using promises to create asynchronous services in Angular

In the preceding section, our current user data was essentially synchronous, so there wasn't an opportunity to observe any asynchronous behavior between the service and component. Services can be very useful for resolving asynchronous dependencies in Angular through the use of promises.

Getting ready

Let's create a BlogPostsService to retrieve our blog posts. We will set this service up as an asynchronous promise that will resolve when it has loaded our posts. We will mock the blog post results for now, but will set it up so that we can eventually swap out with the internals to use an API request instead.

Before we get started, we'll once again scaffold...
