**What**
- Add support for defining outlet routes using `@`, e.g. `/src/admin/routes/brands/@create/page.tsx`
- Add support for exporting a `loader` from a route file.
- Add support for exporting a `handle` from a route file.
Example usage of a loader and handle:
```tsx
// src/admin/routes/articles/[id]/page.tsx
import { Button, Container, Heading } from "@medusajs/ui";
import {
Link,
LoaderFunctionArgs,
Outlet,
UIMatch,
useLoaderData,
} from "react-router-dom";
export async function loader({ params }: LoaderFunctionArgs) {
const { id } = params;
return {
id,
};
}
export const handle = {
breadcrumb: (match: UIMatch<{ id: string }>) => {
const { id } = match.params;
return `#${id}`;
},
};
const ProfilePage = () => {
const { id } = useLoaderData() as Awaited<ReturnType<typeof loader>>;
return (
<div>
<Container className="flex justify-between items-center">
<Heading>Article {id}</Heading>
<Button size="small" variant="secondary" asChild>
<Link to="edit">Edit</Link>
</Button>
</Container>
{/* This will be used for the next example of an Outlet route */}
<Outlet />
</div>
);
};
export default ProfilePage;
```
In the above example we are passing data to the route from a loader, and defining a breadcrumb using the handle.
Example of a outlet route:
```tsx
// src/admin/routes/articles/[id]/@edit/page.tsx
import { Button, Container, Heading } from "@medusajs/ui";
const ProfileEditPage = () => {
return (
<div>
{/* Form goes here */}
</div>
);
};
export default ProfileEditPage;
```
This outlet route will be rendered in the <Outlet /> in the above example when the URL is /articles/1/edit

**What**
- Adds missing Metadata form for collections
- Fixes type of metadata in update payload
- Fixes an issue where deleting the last row of a metadata form would prevent adding new ones.
Resolves SUP-784
Resolves CMRC-627
**What**
- If the session expired, and the user then navigated to a route with no loader the request for the user info in the sidebar would fail causing the app to crash as we didn't have an errorElement wrapping the app shell.
- This PR adds a top level errorElement which handles errors that are outside of a page context, such as in the sidebar.
**What**
- Adds Breadcrumb component to all routes that needs breadcrumbs.
- The Breadcrumb components use a combination of loader data and useQuery to ensure that the displayed value is kept up to date if the underlying data is changed via a mutation.
- Also fixes a couple of places where the breadcrumb was not setup correctly.
Resolves CMRC-688
**What**
- Renames /admin-next -> /admin
- Renames @medusajs/admin-sdk -> @medusajs/admin-bundler
- Creates a new package called @medusajs/admin-sdk that will hold all tooling relevant to creating admin extensions. This is currently `defineRouteConfig` and `defineWidgetConfig`, but will eventually also export methods for adding custom fields, register translation, etc.
- cc: @shahednasser we should update the examples in the docs so these functions are imported from `@medusajs/admin-sdk`. People will also need to install the package in their project, as it's no longer a transient dependency.
- cc: @olivermrbl we might want to publish a changelog when this is merged, as it is a breaking change, and will require people to import the `defineXConfig` from the new package instead of `@medusajs/admin-shared`.
- Updates CODEOWNERS so /admin packages does not require a review from the UI team.
