Circular Dependency Breaking Application Startup
Application fails to start with circular dependency error. Module A imports Module B which imports Module A, creating a cycle that prevents initialization. This often surfaces after refactoring when reorganizing modules.
The error message clearly indicates a circular dependency but resolving it requires understanding module relationships.
Error Messages You Might See
Common Causes
- Service A injects Service B which injects Service A
- Parent and child components/modules import each other
- Shared utility imported by both, but utility also imports both
- Misunderstanding of dependency direction (should be parent → child, not bidirectional)
- Barrel exports (index.js) importing too broadly
How to Fix It
Refactor to break cycle: extract shared logic to third module. Use lazy initialization (Lazy

I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**

Get HelpFrequently Asked Questions
How to detect circular dependencies?
Build system usually shows them with stack trace. Draw dependency graph: A→B→A is circular. Should be acyclic.
How to break cycles?
Extract shared code to third module C: A→C, B→C (no A↔B). Or make one unidirectional: A→B but not B→A.
When should lazy loading be used?
When you need bidirectional relationships despite good design. @Lazy delays initialization until actually used.
