Type of Apex Trigger frameworks in Salesforce?

There are different trigger frameworks available in the market for Salesforce but in this post, we will talk about them.

  1. Trigger Handler Pattern
  2. Trigger Framework using a Virtual Class
  3. Trigger Framework using an Interface
  4. An architecture framework to handle triggers

#1 Trigger Handler Pattern

Please check this post to learn about the Trigger Handler pattern and code. Let’s talk about the advantages of the Trigger Handler pattern.

  1. Apex Class that handles trigger logic
  2. Allows code to be called from other code or tests
  3. Uses specific Trigger contexts and Trigger variables for routing
  4. Keep Triggers Simple
  5. Allow for greater flexibility
  6. Make code reusable
  7. Unit tests are much easier

What is missing in the Handler pattern ?

  1. Still duplicated code in every trigger
  2. How can we simplify things?
  3. How can we make our process repeatable?

#2 Trigger Framework using a Virtual Class

Please check this post to learn more about the Virtual Class Trigger Framework. This trigger framework bundles a single TriggerHandler base class that you can inherit from in all of your trigger handlers. The base class includes context-specific methods that are automatically called when a trigger is executed

Trigger Framework using a Virtual Class

  •  1 line trigger
  • Only need to add handler methods that we want to use
  • All routing is handled for us

#3 Trigger Framework using an Interface

  1. Hi All,

    Firs of all, thank you so much for this blog, it’s really helpfull to me.

    I’d like to view the code related with each framework. But, the link in the “Trigger framework using an interface” section send me to http://chrisaldridge.com/triggers/lightweight-apex-trigger-framework/. However, that page give the following error:
    Forbidden
    You don’t have permission to access /triggers/lightweight-apex-trigger-framework/ on this server.

    Could you correct this please so I can access to the code?

    Thanks in advance.

    Regards,

    Juan.

  2. Hi Amit,

    The given links are not working for:
