n8n-conventions

n8n backend conventions require the Controller-Service-Repository pattern, dependency injection, and strict TypeScript rules. Following these patterns ensures consistency and maintainability across the project's codebase.

For n8n error handling and testing, use Vitest and Playwright frameworks. The conventions provide critical rules for error handling patterns and specify common command-line patterns for running build, type checking, and linting tasks.

Yes, n8n frontend development uses Vue 3 alongside CSS variables and i18n. The conventions outline specific best practices to ensure frontend components remain consistent and maintainable across the project.

n8n supports SQLite and PostgreSQL databases. The required testing frameworks are Vitest for unit tests and Playwright for end-to-end testing, ensuring comprehensive coverage across frontend and backend codebases.

To reference n8n build, type checking, and linting commands, consult the conventions skill. It details common command-line patterns needed to maintain code quality and execute standard development workflows.

The best way to structure an n8n backend service is using the Controller-Service-Repository pattern with dependency injection. This ensures your new code matches established project conventions and maintains architectural integrity.
