NogginErrorCode

The (closed-ish) union of stable error code strings. New codes can be added without a breaking change; renamed / removed codes always are one. Hosts that render user-facing strings key off this.

  | "noggin-error"
  | "no-active-item"
  | "no-file"
  | "no-location"
  | "no-scheme"
  | "no-provider"
