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.

Lightning Components, as their name suggests, are components, or building blocks for developing applications. Lightning is built on top of the open source Aura JavaScript application development framework. You can read more about the Aura open source project at Aura is event driven, and as a result, so are lightning components. Whenever you are working with components, you'll often run into tags that start with Aura. For instance, when you create a new component, the system will scaffold out the bare minimum component needed to work, something like this:

Aura components are actually bundles of many different files separated nicely by concern. Not all of the files need to be populated; for instance, the renderer file isn't required. In the...
