Take your automation to the next level with Apex triggers in Salesforce. This guide by CloudVandana covers best practices, tips, and tricks for leveraging Apex triggers in Salesforce.

Apex Triggers in Salesforce

Apex triggers are an incredibly useful tool for automating processes in Salesforce. With this guide, you’ll learn about their capabilities, best practices for using them, and tips for getting the most out of Apex triggers.

Analyze Your Business Requirements for Apex Triggers

Before you start implementing Apex triggers, it’s important to take a step back and review what your business needs are. Ensure that your requirements are not already being met by Salesforce automation tools such as Process Builder, Flow, or Workflow. If Apex triggers are necessary, you should determine the trigger point and the action that it will take in order to accomplish the desired result. This will help you create an efficient, effective automated process.

Use Context Variables Specifically

It’s important to use context variables when working with Apex triggers. Context variables are global variables that provide an entry point for the non-deterministic actions of a trigger so that it can be managed. Use respective context variables for all the effects of your trigger rather than relying on some specific order of execution that Salesforce does not guarantee. This will ensure your triggers execute predictably, regardless of order or timing in Salesforce system events.

Always Write Test Classes

Writing test classes to accompany your Apex triggers is one of the best practices for developing with Salesforce. Test classes will create a safety net when debugging or changing existing code. They can also provide metrics on how well a trigger is performing, giving insight into how it could be improved. With test classes in place, you can verify that all resulting consequences are running as expected and diagnose any issues quickly and accurately.

Design Trigger Handlers

Trigger handlers are classes used by triggers to control which logic is executed for each type of operation, such as insert, update, or delete. This allows you to separate out how records will be processed when they’re pushed into the system. Put your logic in separate handler methods and have the trigger call them to keep your code tight and organized. This will make it easier to debug and maintain later on.

Create an Exception Logging Framework

By setting up an exception logging framework, you can track errors that arise in your Salesforce application. This will give you clarity on which triggers are failing to perform as expected and provide an actionable solution. To get started, create a custom exception object with fields such as error_message, process_name, and error_code, and write a trigger that collects the error data upon an update. From there, create a workflow rule to send an email notification when certain criteria are met.
