How does this skill help with dependency resolution?

It identifies missing providers, exports, or incorrect module imports that trigger the common 'Nest can't resolve dependencies' error and suggests the correct module structure.

Does it support NestJS microservices?

It includes debugging strategies for message pattern mismatches, transport configuration errors (TCP, Redis, etc.), and serialization/deserialization issues.

Does it include testing support?

Yes, it offers patterns for @nestjs/testing utilities, including provider overriding and E2E test configuration for more reliable test suites.

Can it help with circular dependencies?

Yes, it provides implementation patterns for using forwardRef() in both modules and services to safely resolve circular loops without breaking the dependency graph.

Can I use this for WebSocket issues?

The skill provides solutions for gateway configuration, CORS issues with Socket.io, and adapter setup problems in NestJS WebSocket implementations.

API Development

Diagnoses and resolves complex NestJS issues ranging from dependency injection errors to microservice communication failures.

About

This skill provides a comprehensive, four-phase methodology for troubleshooting NestJS applications. It systematically addresses common framework-specific bottlenecks such as 'Nest can't resolve dependencies' errors, circular module dependencies, and misconfigured guards or interceptors. By offering pre-built patterns for validation pipes, WebSocket gateways, and microservice transport layers, it helps developers reduce downtime and maintain clean architectural standards in their backend services.

Key Features

Microservice and WebSocket communication debugging
Validation Pipe and DTO transformation error resolution
Circular dependency identification and forwardRef implementation
Guard, Interceptor, and Middleware troubleshooting patterns
Dependency injection and module resolution diagnostics

Use Cases

Resolving 'Nest can't resolve dependencies' errors during application startup
Troubleshooting failed message patterns and transport issues in microservice architectures
Fixing broken authentication guards or logging interceptors across modules
