10 Apex Coding Patterns Every Salesforce Developer Should Know

Salesforce development is booming, with the Salesforce ecosystem expected to generate 11.6 million jobs and $2.03 trillion in new business revenues globally by 2028 (IDC and Salesforce Research, February 2024). As Salesforce continues to lead the CRM market, mastering Apex coding patterns is crucial for developers aiming to build robust, scalable, and efficient solutions.

Here are ten essential Apex coding patterns that every Salesforce developer should know:

1. Singleton Pattern

Ensures a class has only one instance and provides a global point of access to it.Essential for managing resource-intensive operations and consistent state management across your Salesforce org.

2. Strategy Pattern

Encapsulates interchangeable algorithms, enabling developers to switch between behaviors dynamically. Particularly useful for discount calculations, data sorting, or validation logic.

3. Factory Pattern

Facilitates object creation without specifying exact class instances, promoting loose coupling and scalability. Ideal for instantiating different Salesforce objects dynamically.

4. Facade Pattern

Simplifies interactions with complex subsystems by providing a straightforward interface.Essential for simplifying integration with external systems and APIs, improving readability and maintainability.

5. Decorator Pattern

Enhances the functionality of an object dynamically without altering its existing structure.Widely used for dynamically adding responsibilities to objects such as logging, validation, or caching.

6. Observer Pattern

Defines a one-to-many dependency between objects, where changes in one object trigger updates in dependent objects. Ideal for implementing event- driven architectures, notably Salesforce platform events.

7. Bulkification Pattern

Critical forSalesforce governor limit compliance, this pattern ensures code handles batch operations efficiently. Salesforce best practices emphasize that developers bulkify their code to handle up to 200 records per transaction seamlessly.

8. Trigger Handler Pattern

Separates trigger logic into manageable units, enhancing readability, maintain ability, and testability. Salesforce strongly recommends this pattern to avoid exceeding governor limits.

9. Service Layer Pattern

Promotes separation of concerns by encapsulating business logic in dedicated classes.Useful for maintaining clear distinctions between presentation logic, business logic, and data access layers.

10. Dependency Injection Pattern

Enhances flexibility by injecting dependencies externally, making components loosely coupled and highly testable. Salesforce developers use this extensively intesting frameworks.

WhyPatterns Matter?

Adopting these Apex coding patterns is strategic. According to Salesforce's Developer Productivity Study(March 2024), developers who consistently apply standard design patterns report up to 40% improvement in code quality and a 30% reduction in development time.
