Hands-On Full Stack Web Development with Aurelia

By: Diego Argüelles Rojas, Erikson Murrugarra

Overview of this book

Hands-On Full Stack Web Development with Aurelia begins with a review of basic JavaScript concepts and the structure of an Aurelia application generated with the Aurelia-CLI tool. You will learn how to create interesting and intuitive application using the Aurelia-Materialize plugin, which implements the material design approach. Once you fully configure a FIFA World Cup 2018 app, you'll start creating the initial components through TDD practices and then develop backend services to process and store all the user data. This book lets you explore the NoSQL model and implement it using one of the most popular NoSQL databases, MongoDB, with some exciting libraries to make the experience effortless. You'll also be able to add some advanced behavior to your components, from managing the lifecycle properly to using dynamic binding, field validations, and the custom service layer. You will integrate your application with Google OAuth Service and learn best practices to secure your applications. Furthermore, you'll write UI Testing scripts to create high-quality Aurelia Apps and explore the most used tools to run end-to-end tests. In the concluding chapters, you'll be able to deploy your application to the Cloud and Docker containers. By the end of this book, you will have learned how to create rich applications using best practices and modern approaches.

Commonly, developers use the common console.log() statement and when it's time to deploy it to UAT or production, they comment all these lines.

Aurelia knows how important this feature is, and guess what—yes, it has its own plugin for this purpose. Let's explore!

Configuring your log manager

By default, Aurelia has the logging API already in their dependencies, so you don't need to run any npm command at this point. Of course, if for some reason that library is missing, you know how to deal with it.

First, we need to create a file to configure our log levels. In the resources folder, create a file called custom-log-appender.js. This name is completely optional; you...
