What I do
Je standardise une gestion d'erreurs typée et composable côté backend.
Rules
- Domain errors : invariants.
- Application errors : orchestration/policies.
- Presentation : mapping vers HTTP.
Template
export class NotFoundError extends Error {
readonly code = 'NOT_FOUND';
}
export function toHttp(err: unknown) {
if (err instanceof NotFoundError) return { status: 404, body: { message: err.message } };
return { status: 500, body: { message: 'Internal error' } };
}
When to use
- Chaque fois qu'un contrôleur commence à contenir des
if/elsed'erreurs.
