NestJS Custom Decorators
When to Use This Skill
Use this skill when:
- Extracting specific properties from request objects
- Creating shortcuts for common parameter patterns
- Setting metadata for guards, interceptors, or filters
- Composing multiple decorators into one
- Implementing role-based access control
- Creating domain-specific abstractions
- Reducing boilerplate in controllers
- Building reusable decorator libraries
What are Custom Decorators?
Decorators are TypeScript/ES2016 features that allow you to add metadata and modify classes, methods, or parameters. NestJS extensively uses decorators and provides utilities to create your own.
