| Add `future.v2_errorBoundary` flag to opt-into v2 `ErrorBoundary` behavior. This removes the separate `CatchBoundary` and `ErrorBoundary` and consolidates them into a single `ErrorBoundary` following the logic used by `errorElement` in React Router. You can then use `isRouteErrorResponse` to differentiate between thrown `Response`/`Error` instances. | ||
|
|
||
| ```jsx | ||
| // Current (Remix v1 default) | ||
| import { useCatch } from "@remix-run/react"; | ||
|
|
||
| export function CatchBoundary() { | ||
| let caught = useCatch(); | ||
| return <p>{caught.status} {caught.data}</p>; | ||
| } | ||
|
|
||
| export function ErrorBoundary({ error }) { | ||
| return <p>{error.message}</p>; | ||
| } | ||
|
|
||
|
|
||
| // Using future.v2_errorBoundary | ||
| import { isRouteErrorResponse, useRouteError } from "@remix-run/react"; | ||
|
|
||
| export function ErrorBoundary() { | ||
| let error = useRouteError(); | ||
|
|
||
| return isRouteErrorResponse(error) ? | ||
| <p>{error.status} {error.data}</p> : | ||
| <p>{error.message}</p>; | ||
| } | ||
| ``` |
