Boost Performance with a Robust Trigger Framework in Salesforce
If you want to make sure of scalability and performance in the Salesforce development, managing Apex triggers is a must.
With a trigger framework, you get a structured approach to organizing and maintaining trigger logic. This way, developers can follow the best practices while maintaining the modularity and reusability of the code.
This blog will walk you through the key components of a trigger framework, its benefits along with its real-world examples.
So, without further ado, let’s dive right into it.
What Is Trigger Framework?
Trigger framework is a structured and organized way to maintain apex trigger in salesforce. It has apex code blocks that are implemented before and after updating the record, like created records, edited, deleted, or undeleted.
A trigger framework is also known for best practices and building code in a modular and maintained manner. Additionally, it keeps up with common challenges such as trigger recursion, governor limits, code maintainability, and more.
Key Advantages of Trigger Framework
- Generate generic code that can be extended for multiple objects & multiple triggers.
- Ensure that your trigger will be consistently handled and that only required code is needed.
- It will easily allow for trigger bypasses.
- Trigger framework can manage & decrease the risk of exceeding salesforce’s governor limits.
- The framework can make maintaining and scaling trigger logic easier as our requirements increase.
Key component of Trigger Framework
Trigger Handler: The trigger handler is used to contain the logic for events and execute the appropriate actions. It also works as the middle layer between trigger and business logic.
Trigger Dispatcher: The trigger dispatcher is used to route the events to the appropriate trigger handler based on the event type and object.
Trigger Context: The trigger context is an object that holds information about the trigger event, including the event type and the records being processed.
Creating a trigger framework for an example:
1. Creating a trigger interface:
2. Create a base trigger handler: This base trigger handler class is used to handle common functionality like enabling/disabling triggers and managing recursion.
3. Develop trigger handler: In this, we can create a handler for the specific object by extending the base trigger handler class and implementing the interface method as per your requirement.
4. Implementing the trigger dispatcher: Using this trigger dispatcher class, we can route events to the appropriate trigger handler.
5. Create trigger: Now we will create a trigger that uses the trigger dispatcher to route events to the corresponding trigger handlers.
Here’s an example of a trigger framework:

Best Practices for Implementing a Trigger Framework
- One Trigger per Object: Limit your triggers to one per object.
- Keep Triggers Lightweight: Make sure that your triggers should only contain the dispatcher call. Keep the business logic within the trigger handlers.
- Use a Modular Approach: Break down complex logic into smaller, reusable methods within your trigger handlers.
- Prevent Recursive Trigger Calls: Implement logic in the base trigger handler to prevent recursive calls, ensuring triggers only execute once per event
- Implement Error Handling: Incorporate error handling within your trigger handlers to gracefully handle exceptions and provide meaningful error messages to users
- Write Test Classes: Develop comprehensive test classes to ensure the functionality of your trigger framework and maintain a high level of code coverage
Real-World Use Cases of Trigger Framework
- Automating Record Assignment: Using a trigger handler to automatically assign records to appropriate users or queues based on specific criteria.
- Data Validation: We must create a trigger handler that validates data on inserting or updating into our org.
- Synchronize Related Records: Develop a trigger handler to maintain data consistency between related records. if we change the child record, it should be reflected in its parent record.
Conclusion:
Triggers are powerful tools in the salesforce, but they require careful management to maintain scalability, maintainability, and performance. By implementing the trigger framework we can develop a scalable solution that meets the evolving needs of the organization. For more updates, stay tuned!
