Mastering Application Development with

By: Kevin J. Poorman

Overview of this book is an extremely powerful, scalable, and secure cloud platform, delivering a complete technology stack, ranging from databases and security to workflow and the user interface. With's cloud platform, you can build any business application and run it on your servers. The book will help you enhance your skillset and develop complex applications using It gets you started with a quick refresher of's development tools and methodologies, and moves to an in-depth discussion of triggers, bulkification, DML order of operations, and trigger frameworks. Next, you will learn to use batchable and schedulable interfaces to process massive amounts of information asynchronously. You will also be introduced to Salesforce Lightning and cover components—including backend (apex) controllers, frontend (JavaScript) controllers, events, and attributes—in detail. Moving on, the book will focus on testing various apex components: what to test, when to write the tests, and—most importantly—how to test. Next, you will develop a changeset and use it to migrate your code from one org to another, and learn what other tools are out there for deploying metadata. You will also use command-line tools to authenticate and access the Rest sObject API and the Bulk sObject API; additionally, you will write a custom Rest endpoint, and learn how to structure a project so that multiple developers can work independently of each other without causing metadata conflicts. Finally, you will take an in-depth look at the overarching best practices for architecture (structure) and engineering (code) applications on the platform.

The SFDC-trigger-framework

A couple of years ago, Salesforce MVP Kevin O'Hara released on GitHub the SFDC-trigger-framework. You can find it at There are a number of trigger frameworks available for the platform, but this one is my favorite and the one I highly recommend. Since SFDC-trigger-framework is a bit of a mouthful, I will refer to it as the framework. The framework allows us to separate the logic from triggers in a way that allows us to create a deterministic order for those triggers to fire, and in a better way, for us to test the logic triggers. Because the trigger interface is controlled by Salesforce, very little of the actual trigger file will be different than traditional trigger development. Specifically, we still have to determine the context of our trigger and specify that in the trigger file for salesforce:
