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.

Exploring @future annotated methods

The @future annotation (pronounced as at future) is, perhaps, the simplest method of asynchronous code execution on the Salesforce1 platform. The @future, is a method annotation that makes the method run asynchronously at some point in the near future. Generally, this happens quite quickly, but no time guarantees are established annotation methods as @future is fantastically useful, but has a number of caveats and limitations that developers must remain mindful of:

  • Most importantly, methods annotated with @future can only accept primitive parameter types. String, Integer, and so on, are your only options.

  • You cannot chain methods annotated with @future. In other words, an @future annotated method cannot be called from another @future annotated method. This is especially crucial to remember when your @future method may result in a trigger firing. If an @future method fires a trigger, that trigger cannot in turn call other @future annotated methods.
