domainErrorHttpStatus

Call Signature

domainErrorHttpStatus(error): DomainErrorHttpStatus

Defined in: packages/ddd-core/http/domain-error-http-status.ts:48

Maps this package’s errors to an HTTP status, for any HTTP framework.

Exception	Status	Message
ConcurrencyConflictError	409 Conflict	the exception’s
EntityNotFoundException	404 Not Found	the exception’s
MissingTenantContextError	500 Internal Server Error	'Internal server error'
any other DomainException	400 Bad Request	the exception’s

A missing tenant is a server misconfiguration, not a caller mistake, so it answers 500 and keeps its message, which names the failed operation, out of the response.

An application maps its own DomainException subclasses first and passes the rest here. Anything that is not a DomainException returns undefined, so the framework’s default handling still applies.

Parameters

error

DomainException

Returns

DomainErrorHttpStatus

Example

An Express error handler

app.use((err, req, res, next) => {
  const mapped = domainErrorHttpStatus(err);
  if (!mapped) return next(err);
  res.status(mapped.statusCode).json(mapped);
});
