Cyclic Dependencies

Cyclic dependencies occur when two or more modules depend on each other directly or indirectly, creating a circular reference. This can lead to several issues:

  • Increased coupling between modules
  • Harder to maintain and test code
  • Potential initialization problems
  • Reduced code reusability

Example​

// Module A
import { B } from './B';
export class A {
  constructor(private b: B) {}
}

// Module B
import { A } from './A';
export class B {
  constructor(private a: A) {}
}

How Forensics Detects Cyclic Dependencies​

Forensics analyzes your codebase to identify cyclic dependencies by:

  1. Building a dependency graph of all modules
  2. Detecting cycles in the graph
  3. Reporting the specific modules involved in each cycle

Resolution Strategies​

To resolve cyclic dependencies, consider:

  1. Dependency Inversion: Use interfaces or abstract classes
  2. Event-based Communication: Implement an event system
  3. Mediator Pattern: Introduce a mediator to handle communication
  4. Refactoring: Split or merge modules to break the cycle
