💻 Code
// @file a.ts import { forwardRef, type PropsWithChildren } from "react"; import { type ExportedType } from "@ts-bug/b"; export type Props = PropsWithChildren<{ // Tile props. active?: ExportedType; }>; export const Component = forwardRef<HTMLLIElement, Props>(() => { return null; }); // @file @ts-bug/src/index.ts import { type ExportedType as NaturalExportedType } from './type' export type ExportedType = NaturalExportedType; // @file @ts-bug/src/type.ts export type ExportedType = 'overlay' | 'rearrange' | 'origin' | 'destination';🙁 Actual behavior
The generated declarations for a.ts contain an invalid import into one of the nested declaration files instead of using the main package export.
// @file a.d.ts import { type PropsWithChildren } from "react"; import { type ExportedType } from "@ts-bug/b"; export type Props = PropsWithChildren<{ active?: ExportedType; }>; export declare const Component: import("react").ForwardRefExoticComponent<{ active?: import("b/dist/types/src/type").ExportedType | undefined; } & { children?: import("react").ReactNode; } & import("react").RefAttributes<HTMLLIElement>>; //# sourceMappingURL=index.d.ts.map🙂 Expected behavior
The declarations should use the main package export.
