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.

Using clicks with code

Within Salesforce circles, it is common to hear debates of clicks versus code or clicks before code. Salesforce is a powerful low-code development platform that has a variety of different tools to enable administrators and those without coding skills to create powerful automated processes. For the remainder of this discussion, I will refer to any individual creating solutions in non-code-based tools exclusively as an administrator, eschewing terms such as citizen developer or other terminology to try and keep things simple. I will also refer to everything that is not programming involving Apex, Visualforce, Aura, or Lightning Web Components on the platform to be one of the declarative tools, and for solutions built using these tools to be built using clicks. This includes formula fields, validation rules, workflow, roll-up summary fields, Process Builder, approval processes, Flows, and reports.

Firstly, anyone building a solution on Salesforce should never...
