--- title: Intercepting Routes description: Use intercepting routes to load a new route within the current layout while masking the browser URL, useful for advanced routing patterns such as modals. related: title: Next Steps description: Learn how to create modals with Intercepted and Parallel Routes. links: - app/api-reference/file-conventions/parallel-routes --- Intercepting routes allows you to load a route from another part of your application within the current layout. This routing paradigm can be useful when you want to display the content of a route without the user switching to a different context. For example, when clicking on a photo in a feed, you can display the photo in a modal, overlaying the feed. In this case, Next.js intercepts the `/photo/123` route, masks the URL, and overlays it over `/feed`. Intercepting routes soft navigation However, when navigating to the photo by clicking a shareable URL or by refreshing the page, the entire photo page should render instead of the modal. No route interception should occur. Intercepting routes hard navigation ## Convention Intercepting routes can be defined with the `(..)` convention, which is similar to relative path convention `../` but for route segments. You can use: - `(.)` to match segments on the **same level** - `(..)` to match segments **one level above** - `(..)(..)` to match segments **two levels above** - `(...)` to match segments from the **root** `app` directory For example, you can intercept the `photo` segment from within the `feed` segment by creating a `(..)photo` directory. Intercepting routes folder structure > **Good to know:** The `(..)` convention is based on _route segments_, not the file-system. For example, it does not consider `@slot` folders in [Parallel Routes](/docs/app/api-reference/file-conventions/parallel-routes). ## Examples ### Modals Intercepting Routes can be used together with [Parallel Routes](/docs/app/api-reference/file-conventions/parallel-routes) to create modals. This allows you to solve common challenges when building modals, such as: - Making the modal content **shareable through a URL**. - **Preserving context** when the page is refreshed, instead of closing the modal. - **Closing the modal on backwards navigation** rather than going to the previous route. - **Reopening the modal on forwards navigation**. Consider the following UI pattern, where a user can open a photo modal from a gallery using client-side navigation, or navigate to the photo page directly from a shareable URL: Intercepting routes modal example In the above example, the path to the `photo` segment can use the `(..)` matcher since `@modal` is a slot and **not** a segment. This means that the `photo` route is only one segment level higher, despite being two file-system levels higher. See the [Parallel Routes](/docs/app/api-reference/file-conventions/parallel-routes#modals) documentation for a step-by-step example, or see our [image gallery example](https://github.com/vercel-labs/nextgram). > **Good to know:** > > - Other examples could include opening a login modal in a top navbar while also having a dedicated `/login` page, or opening a shopping cart in a side modal.
