Problem JSON (RFC 7807)

Bklar supports RFC 7807 Problem Details for HTTP APIs. Enable it via the errorFormat option.

Configuration

const app = Bklar({
  errorFormat: "problemJson",
});

With problemJson enabled, error responses use the standard structure:

{
  "type": "https://httpstatuses.io/404",
  "title": "Resource not found",
  "status": 404,
  "detail": "User not found"
}

Field	Description
`type`	URI identifying the problem type
`title`	Short human-readable summary
`status`	HTTP status code
`detail`	Human-readable explanation

The default format ("basic") returns { "message": "..." } instead.
