Professional programmers know that logging errors and being able to track what is going on within an Angular application is essential. In this course, Building Reusable Angular Services: Logging, you'll learn how to design an Angular service to perform logging more efficiently and with more flexibility than just using console.log(), by creating an extensible Angular service to log any data to a variety of locations. First, you'll explore how to build a simple console logging class, a class to log to local storage, and a class to post log information to a Web API. Additionally, you'll delve into building different types of log entries, such as debug, informational, error, and warnings. Finally, you'll discover how to create a JSON configuration file to control where you log the data. By the end of this course, you'll have a great start on your logging service that can be used in your own applications. This service can replace all your console.log() calls to provide a better, and more flexible approach to logging.
