Sometimes, we want to rewrite the protected routes using TypeScript and React-Router 6.
In this article, we’ll look at how to rewrite the protected routes using TypeScript and React-Router 6.
How to rewrite the protected routes using TypeScript and React-Router 6?
To rewrite the protected routes using TypeScript and React-Router 6, we can define the type for the route props ourselves.
For instance, we write
export type ProtectedRouteProps = {
isAuthenticated: boolean;
authenticationPath: string;
outlet: JSX.Element;
};
export default function ProtectedRoute({
isAuthenticated,
authenticationPath,
outlet,
}: ProtectedRouteProps) {
if (isAuthenticated) {
return outlet;
} else {
return <Navigate to={{ pathname: authenticationPath }} />;
}
}
to define the ProtectedRouteProps with some properties for the ProtectedRoute component props.
Then we can destructure the props and use them in the component.
We render outlet, which has the route component if isAuthenticated is true.
Next, we can use ProtectedRoute by writing
const App = () => {
//...
const defaultProtectedRouteProps: Omit<ProtectedRouteProps, "outlet"> = {
isAuthenticated: !!sessionContext.isAuthenticated,
authenticationPath: "/login",
};
return (
<div>
<Routes>
<Route path="/" element={<Homepage />} />
<Route
path="dashboard"
element={
<ProtectedRoute
{...defaultProtectedRouteProps}
outlet={<Dashboard />}
/>
}
/>
<Route
path="nested"
element={
<ProtectedRoute
{...defaultProtectedRouteProps}
outlet={<Layout />}
/>
}
>
<Route path="one" element={<Protected />} />
<Route path="two" element={<Protected />} />
</Route>
<Route path="login" element={<Login />} />
</Routes>
</div>
);
};
to add the protected routes with the ProtectedRoute component by setting them as values for the Route component’s element prop.
Conclusion
To rewrite the protected routes using TypeScript and React-Router 6, we can define the type for the route props ourselves.
