Building Solo: Errors
- When developing alone, implementing error handling can be challenging, especially with separate backend and frontend setups.
- Having a clear plan for error management can make it convenient for both the backend and frontend.
- Implementing an enum on the backend to indicate error types can simplify error handling without relying solely on status codes or messages.
- FastAPI allows for a structured error architecture using exception handlers to manage various error types.
- Mapping error types to specific classes with messages and information can enhance error handling and reduce boilerplate code.
- On the frontend (NextJS), defining error types and using classes to handle errors can streamline the error processing from the backend.
- Errors are categorized as common or action-based, allowing users to take appropriate actions for different error scenarios.
- Error types are mapped to corresponding UI classes using a factory pattern for efficient error handling and presentation.
- The error-handling architecture offers a good balance between structure, flexibility, and user experience for solo developers or small teams.
- Pros include clear error typing, frontend ownership of UX, extensibility with OOP, and centralized backend handling.
