MEAN Cookbook

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.

Retrieving API data using HTTP services in Angular

Single page applications such as Angular are often a component in service-oriented architecture (SOA) that relies on external web services as the data sources for our web application. Introducing networked services into our application also brings with it a lot of asynchronous behaviors that we have to resolve both technically, and in our user interface.

The most common form of interaction between these services and a frontend application is via an HTTP request to a RESTful API. In this section, we will cover how to connect to a RESTful API in Angular and work with that data in our application.
