Overview of this book

As applications built on the Salesforce platform are now a key part of many organizations, developers are shifting focus to Apex, Salesforce’s proprietary programming language. As a Salesforce developer, it is important to understand the range of tools at your disposal, how and when to use them, and best practices for working with Apex. Mastering Apex Programming will help you explore the advanced features of Apex programming and guide you in delivering robust solutions that scale. This book starts by taking you through common Apex mistakes, debugging, exception handling, and testing. You'll then discover different asynchronous Apex programming options and develop custom Apex REST web services. The book shows you how to define and utilize Batch Apex, Queueable Apex, and Scheduled Apex using common scenarios before teaching you how to define, publish, and consume platform events and RESTful endpoints with Apex. Finally, you'll learn how to profile and improve the performance of your Apex application, including architecture trade-offs. With code examples used to facilitate discussion throughout, by the end of the book, you'll have developed the skills needed to build robust and scalable applications in Apex.

An overview of event-driven architecture and the event bus

At the time of writing, I have been working with the Salesforce platform for a little over 11 years. In that time, what started as a platform based primarily around sales and service-related applications has grown into a broad platform, delivering all manner of applications. In my work with Salesforce, I have delivered applications outside the traditional sales, service, and marketing business areas to banks, insurers, pharmaceutical companies, research organizations, retailers, fashion brands, and charities, to name just a handful.

As the scope and type of application on the platform has grown, architects have had to think of different ways to organize and manage applications to enable organizations to continue to deliver rapidly and operate at scale. Salesforce introduced platform events to assist architects and developers in meeting these needs using event-driven architectures.
