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.

Summary

In this chapter, we have covered a number of the different architectural decisions that will impact the performance of your application, both in terms of resource usage and developer productivity. We started by discussing the impacts of using licks or code in our application and how to determine the best solution at the time. Following this, we moved on to discuss code structure and linting to help ensure that common bugs or performance issues were caught early.

This led into a more general discussion of the use of object-oriented patterns in Apex and how they can help make it easier to test and profile our code for scale, as well as ensure that we can modularize our code for increased developer performance as we make changes in the future. From here we dove into specific architectural trade-offs that you need to consider when designing different types of solutions using Apex.

Finally, we finished the chapter with a discussion on managing the performance of an application...
