Router

The router has been entirely rewritten in the 0.4 release to provide type safe routes. This guide serves to help you upgrade your project to the new router. For more information on the router, see the router guide.

Defining Your Router

Previously, you defined your route with components:

rsx! {
    Router::<Route> {
        Route { to: "/home", Home {} }
        Route { to: "/blog", Blog {} }
        // BlogPost has a dynamic id
        Route { to: "/blog/:id", BlogPost {} }
    }
}

Now you must define your routes as an enum of possible routes:

use dioxus_router::prelude::*;
use dioxus::prelude::*;

#[derive(Routable, PartialEq, Debug, Clone)]
enum Route {
    #[route("/home")]
    // This route will render the Home component with the HomeProps props. (make sure you have the props imported)
    // You can modify the props by passing extra arguments to the macro. For example, if you want the Home variant to render a component called Homepage, you could use:
    // #[route("/home", Homepage)]
    Home {},
    #[route("/blog")]
    Blog {},
    // BlogPost has a dynamic id
    #[route("/blog/:id")]
    BlogPost {
        id: usize
    }
}

#[component]
fn Home(cx: Scope) -> Element {
    todo!()
}

#[component]
fn Blog(cx: Scope) -> Element {
    todo!()
}

#[component]
fn BlogPost(cx: Scope, id: usize) -> Element {
    // Note that you have access to id here in a type safe way without calling any extra functions!
    todo!()
}

Linking to routes

Now that routes are enums, you should use the enum as the route in Links. If you try to link to a route that does not exist, you will get a compiler error.

use dioxus::prelude::*;
use dioxus_router::prelude::*;

fn Component(cx: Scope) -> Element {
    render! {
        Link {
            to: Route::BlogPost { id: 123 },
            "blog post"
        }
    }
}

To link to external routes, you can use a string:

use dioxus::prelude::*;
use dioxus_router::prelude::*;

fn Component(cx: Scope) -> Element {
    render! {
        Link {
            to: "https://google.com",
            "google"
        }
    }
}

use_router

The use_router hook has been split into two separate hooks: the use_route hook and the use_navigator hook.

use_route

The new use_route hook lets you read the current route:

use dioxus::prelude::*;
use dioxus_router::prelude::*;

#[derive(Clone, Routable)]
enum Route {
    #[route("/")]
    Index {},
}

fn App(cx: Scope) -> Element {
    render! {
        h1 { "App" }
        Router::<Route> {}
    }
}

#[component]
fn Index(cx: Scope) -> Element {
    // Read from (and subscribe to the current route)
    let path = use_route(&cx).unwrap();
    render! {
        h2 { "Current Path" }
        p { "{path}" }
    }
}

use_navigator

use_navigator lets you change the route programmatically:

src/navigator.rs
#[component]
fn Home(cx: Scope) -> Element {
    let nav = use_navigator(cx);

    // push
    nav.push(Route::PageNotFound { route: vec![] });

    // replace
    nav.replace(Route::Home {});

    // go back
    nav.go_back();

    // go forward
    nav.go_forward();

    render! {
        h1 { "Welcome to the Dioxus Blog!" }
    }
}

You can read more about programmatic navigation in the Router Book.

New features

In addition to these changes, there have been many new features added to the router:
