| # Future Flags | ||
|
|
||
| The following future flags are stable and ready to adopt. To read more about future flags see [Development Strategy](../guides/api-development-strategy) | ||
|
|
||
| ## Update to latest v6.x | ||
|
|
||
| First update to the latest minor version of v6.x to have the latest future flags. | ||
|
|
||
| 👉 **Update to latest v6** | ||
|
|
||
| ```shellscript nonumber | ||
| npm install react-router-dom@6 | ||
| ``` | ||
|
|
||
| ## v7_relativeSplatPath | ||
|
|
||
| **Background** | ||
|
|
||
| Changes the relative path matching and linking for multi-segment splats paths like `dashboard/*` (vs. just `*`). [View the CHANGELOG](https://github.com/remix-run/react-router/blob/main/packages/react-router-dom/CHANGELOG.md#minor-changes-2) for more information. | ||
|
|
||
| 👉 **Enable the flag** | ||
|
|
||
| Enabling the flag depends on the type of router: | ||
|
|
||
| ```tsx | ||
| <BrowserRouter | ||
| future={{ | ||
| v7_relativeSplatPath: true, | ||
| }} | ||
| /> | ||
| ``` | ||
|
|
||
| ```tsx | ||
| createBrowserRouter(routes, { | ||
| future: { | ||
| v7_relativeSplatPath: true, | ||
| }, | ||
| }); | ||
| ``` | ||
|
|
||
| **Update your Code** | ||
|
|
||
| If you have any routes with a path + a splat like `<Route path="dashboard/*">` and has relative links like `<Link to="relative">` or `<Link to="../relative">` beneath it, you will need to update your code. | ||
|
|
||
| 👉 **Split the `<Route>` into two** | ||
|
|
||
| Split any multi-segment splat `<Route>` into a parent route with the path and a child route with the splat: | ||
|
|
||
| ```diff | ||
| <Routes> | ||
| <Route path="/" element={<Home />} /> | ||
| - <Route path="dashboard/*" element={<Dashboard />} /> | ||
| + <Route path="dashboard"> | ||
| + <Route path="*" element={<Dashboard />} /> | ||
| + </Route> | ||
| </Routes> | ||
|
|
||
| // or | ||
| createBrowserRouter([ | ||
| { path: "/", element: <Home /> }, | ||
| { | ||
| - path: "dashboard/*", | ||
| - element: <Dashboard />, | ||
| + path: "dashboard", | ||
| + children: [{ path: "*", element: <Dashboard /> }], | ||
| }, | ||
| ]); | ||
| ``` | ||
|
|
||
| 👉 **Update relative links** | ||
|
|
||
| Update any `<Link>` elements within that route tree to include the extra `..` relative segment to continue linking to the same place: | ||
|
|
||
| ```diff | ||
| function Dashboard() { | ||
| return ( | ||
| <div> | ||
| <h2>Dashboard</h2> | ||
| <nav> | ||
| - <Link to="/">Dashboard Home</Link> | ||
| - <Link to="team">Team</Link> | ||
| - <Link to="projects">Projects</Link> | ||
| + <Link to="../">Dashboard Home</Link> | ||
| + <Link to="../team">Team</Link> | ||
| + <Link to="../projects">Projects</Link> | ||
| </nav> | ||
|
|
||
| <Routes> | ||
| <Route path="/" element={<DashboardHome />} /> | ||
| <Route path="team" element={<DashboardTeam />} /> | ||
| <Route | ||
| path="projects" | ||
| element={<DashboardProjects />} | ||
| /> | ||
| </Routes> | ||
| </div> | ||
| ); | ||
| } | ||
| ``` | ||
|
|
||
| ## v7_startTransition | ||
|
|
||
| **Background** | ||
|
|
||
| This uses `React.useTransition` instead of `React.useState` for Router state updates. View the [CHANGELOG](https://github.com/remix-run/react-router/blob/main/CHANGELOG.md#v7_starttransition) for more information. | ||
|
|
||
| 👉 **Enable the flag** | ||
|
|
||
| ```tsx | ||
| <BrowserRouter | ||
| future={{ | ||
| v7_startTransition: true, | ||
| }} | ||
| /> | ||
|
|
||
| // or | ||
| <RouterProvider | ||
| future={{ | ||
| v7_startTransition: true, | ||
| }} | ||
| /> | ||
| ``` | ||
|
|
||
| 👉 **Update your Code** | ||
|
|
||
| You don't need to update anything unless you are using `React.lazy` _inside_ of a component. | ||
|
|
||
| Using `React.lazy` inside of a component is incompatible with `React.useTransition` (or other code that makes promises inside of components). Move `React.lazy` to the module scope and stop making promises inside of components. This is not a limitation of React Router but rather incorrect usage of React. | ||
|
|
||
| ## v7_fetcherPersist | ||
|
|
||
| <docs-warning>If you are not using a `createBrowserRouter` you can skip this</docs-warning> | ||
|
|
||
| **Background** | ||
|
|
||
| The fetcher lifecycle is now based on when it returns to an idle state rather than when its owner component unmounts: [View the CHANGELOG](https://github.com/remix-run/react-router/blob/main/CHANGELOG.md#persistence-future-flag-futurev7_fetcherpersist) for more information. | ||
|
|
||
| **Enable the Flag** | ||
|
|
||
| ```tsx | ||
| createBrowserRouter(routes, { | ||
| future: { | ||
| v7_fetcherPersist: true, | ||
| }, | ||
| }); | ||
| ``` | ||
|
|
||
| **Update your Code** | ||
|
|
||
| It's unlikely to affect your app. You may want to check any usage of `useFetchers` as they may persist longer than they did before. Depending on what you're doing, you may render something longer than before. | ||
|
|
||
| ## v7_normalizeFormMethod | ||
|
|
||
| <docs-warning>If you are not using a `createBrowserRouter` you can skip this</docs-warning> | ||
|
|
||
| This normalizes `formMethod` fields as uppercase HTTP methods to align with the `fetch()` behavior. [View the CHANGELOG](https://github.com/remix-run/react-router/blob/main/CHANGELOG.md#futurev7_normalizeformmethod) for more information. | ||
|
|
||
| 👉 **Enable the Flag** | ||
|
|
||
| ```tsx | ||
| createBrowserRouter(routes, { | ||
| future: { | ||
| v7_normalizeFormMethod: true, | ||
| }, | ||
| }); | ||
| ``` | ||
|
|
||
| **Update your Code** | ||
|
|
||
| If any of your code is checking for lowercase HTTP methods, you will need to update it to check for uppercase HTTP methods (or call `toLowerCase()` on it). | ||
|
|
||
| 👉 **Compare `formMethod` to UPPERCASE** | ||
|
|
||
| ```diff | ||
| -useNavigation().formMethod === "post" | ||
| -useFetcher().formMethod === "get"; | ||
| +useNavigation().formMethod === "POST" | ||
| +useFetcher().formMethod === "GET"; | ||
| ``` | ||
|
|
||
| ## v7_partialHydration | ||
|
|
||
| <docs-warning>If you are not using a `createBrowserRouter` you can skip this</docs-warning> | ||
|
|
||
| This allows SSR frameworks to provide only partial hydration data. It's unlikely you need to worry about this, just turn the flag on. [View the CHANGELOG](https://github.com/remix-run/react-router/blob/main/CHANGELOG.md#partial-hydration) for more information. | ||
|
|
||
| 👉 **Enable the Flag** | ||
|
|
||
| ```tsx | ||
| createBrowserRouter(routes, { | ||
| future: { | ||
| v7_partialHydration: true, | ||
| }, | ||
| }); | ||
| ``` |
