| * In this version of Next.js the `params` prop passed to Layouts, Pages, and other Segments is a Promise. | |
| * However to facilitate migration to this new Promise type you can currently still access params directly on the Promise instance passed to these Segments. | |
| * The `UnsafeUnwrappedSearchParams` type is available if you need to temporarily access the underlying params without first awaiting or `use`ing the Promise. | |
| * | |
| * In a future version of Next.js the `params` prop will be a plain Promise and this type will be removed. | |
| * | |
| * Typically instances of `params` can be updated automatically to be treated as a Promise by a codemod published alongside this Next.js version however if you | |
| * have not yet run the codemod of the codemod cannot detect certain instances of `params` usage you should first try to refactor your code to await `params`. | |
| * | |
| * If refactoring is not possible but you still want to be able to access params directly without typescript errors you can cast the params Promise to this type | |
| * | |
| * ```tsx | |
| * type Props = { searchParams: Promise<{ foo: string }> } | |
| * | |
| * export default async function Page(props: Props) { | |
| * const { searchParams } = (props.searchParams as unknown as UnsafeUnwrappedSearchParams<typeof props.searchParams>) | |
| * return ... | |
| * } | |
| * ``` | |
| * | |
| * This type is marked deprecated to help identify it as target for refactoring away. | |
| * | |
| * @deprecated | |
