A lightweight trigger handler framework for Salesforce Apex.

Complex Apex trigger frameworks getting you down? This is a very lightweight trigger framework to get you started.

Full details and implementation steps can be found on my blog at http://chrisaldridge.com.

How to implement this trigger pattern

  1. Copy the ITriggerHandler and TriggerDispatcher classes into your org (in that order). Or you can use the Deploy To Salesforce link below.
  2. Create an objectTriggerHandler class (such as OpportunityTriggerHandler), which implements the ITriggerHandler interface. Have a look at the AccountTriggerHandler class in this repository for a working example.
  3. Add logic for the methods you require. For example, if you want some BeforeInsert logic, add it to the BeforeInsert method in your handler class.
  4. Create a trigger for your object which fires on all events. If you're using MavensMate/Sublime Text, there is a template for this when you create a new trigger. Take a look at the example AccountTrigger in this repository if you're not sure.
  5. Call the static TriggerDispatcher.Run method from your trigger. Pass it a new instance of your TriggerHandler class as an argument
  6. Take a tea break. You've earned it.
