# Navigation Failures
|
||||
|
||||
Some specific operations can cause a failure within router operations. The
|
||||
subchapters contain information on how the router lets us handle such failures.
|
||||
|
||||
# External Navigation Failure
|
||||
|
||||
> This section doesn't apply when specifying a `target` on a [`Link`]. See the
|
||||
> chapter about [external navigation](../navigation/external.md) for more
|
||||
> details.
|
||||
|
||||
When we ask the router to navigate to an external target, either through
|
||||
[programmatic navigation](../navigation/programmatic.md) or a
|
||||
[redirect](../routes/multiple-and-redirect.md#redirects) the router needs to
|
||||
navigate to an external target without being able to rely on an anchor element.
|
||||
|
||||
This will only work in the browser, when using either [`WebHistory`] or
|
||||
[`WebHashHistory`].
|
||||
|
||||
## Failure handling
|
||||
|
||||
When the router encounters an external navigation it cannot fulfill, it changes
|
||||
the path to `/` and shows some fallback content.
|
||||
|
||||
> You can detect if the router is in the external navigation failure handling
|
||||
> state by [checking](../navigation/name.md#check-if-a-name-is-present) if the
|
||||
> [`FailureExternalNavigation`] name is present.
|
||||
|
||||
The default fallback explains to the user that the navigation was unsuccessful
|
||||
and provides them with a [`Link`] to fulfill it manually. It also allows them to
|
||||
go back to the previous page.
|
||||
|
||||
You can override it by setting the `failure_external_navigation` value of the
|
||||
[`RouterConfiguration`]. The external URL will be provided via the
|
||||
[`FailureExternalNavigation`] parameter.

# History Providers
|
||||
|
||||
In order to provide the ability to traverse the navigation history, the router
|
||||
uses [`HistoryProvider`]s. Those implement the actual back-and-forth
|
||||
functionality.
|
||||
[`HistoryProvider`]s are used by the router to keep track of the navigation history
|
||||
and update any external state (e.g. the browser's URL).
|
||||
|
||||
The router provides five [`HistoryProvider`]s, but you can also create your own.
|
||||
The five default implementations are:
|
||||
|
||||
- The [`MemoryHistory`] is a custom implementation that works in memory.
|
||||
- The [`WebHistory`] integrates with the browsers URL.
|
||||

|
||||
|
||||
> Make sure you added the `dioxus-router` dependency as explained in the

|
||||
In most cases, we want to add the router to the root component of our app. This
|
||||
way, we can ensure that we have access to all its functionality everywhere.
|
||||
|
||||
First, we define the router with the router macro:
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus;
|
||||
use dioxus::prelude::*;
|
||||
# extern crate dioxus_router;
|
||||
use dioxus_router::prelude::*;
|
||||
# extern crate dioxus_ssr;
|
||||
|
||||
// This is the component we pass to dioxus when launching our app.
|
||||
fn App(cx: Scope) -> Element {
|
||||
// Here we add the router. All components inside `App` have access to its
|
||||
// functionality.
|
||||
let routes = use_router(
|
||||
cx,
|
||||
// The router can be configured with this parameter.
|
||||
&|| RouterConfiguration {
|
||||
# synchronous: true,
|
||||
..Default::default()
|
||||
},
|
||||
// This tells the router about all the routes in our application. As we
|
||||
// don't have any, we pass an empty segment
|
||||
&|| Segment::empty()
|
||||
);
|
||||
|
||||
render! {
|
||||
h1 { "Our sites title" }
|
||||
|
||||
// The Outlet tells the Router where to render active content.
|
||||
Outlet { }
|
||||
}
|
||||
}
|
||||
#
|
||||
# let mut vdom = VirtualDom::new(App);
|
||||
# let _ = vdom.rebuild();
|
||||
# assert_eq!(
|
||||
# dioxus_ssr::render(&vdom),
|
||||
# "<h1>Our sites title</h1>"
|
||||
# );

||||
```
|
||||
|
||||
[`use_router`]: https://docs.rs/dioxus-router/latest/dioxus_router/hooks/fn.use_router.html
|
||||
Then we render the router with the [`Router`] component.
|
||||
|
||||
```rust, no_run
|
||||

# External Navigation
|
||||
|
||||
In modern apps, and especially on the web, we often want to send our users to an
|
||||
other website. [`External`] allows us to make a [`Link`] navigate to an
|
||||
external page.
|
||||
|
||||
> You might already now about
|
||||
> [external navigation failures](../failures/external.md). The [`Link`]
|
||||
> component doesn't rely on the code path where those originate. Therefore a
|
||||
> [`Link`] will never trigger an external navigation failure.
|
||||
|
||||
Strictly speaking, a [`Link`] is not necessary for navigating to external
|
||||
targets, since by definition the router cannot handle them internally. However,
|
||||
the [`Link`] component is more convenient to use, as it automatically sets the
|
||||
`rel` attribute for the link, when the target is external.
|
||||
|
||||
## Code Example
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.

||||
# extern crate dioxus;

|
||||
However, we cannot do that when using the router for three reasons:
|
||||
|
||||
1. Anchor tags make the browser load a new page from the server. This takes a
|
||||
lot of time, and it is much faster to let the router handle the navigation
|
||||
client-side.
|
||||
2. Navigation using anchor tags only works when the app is running inside a
|
||||
browser. This means we cannot use them inside apps using Dioxus Desktop.
|
||||
3. Anchor tags cannot check if the target page exists. This means we cannot
|
||||
prevent accidentally linking to non-existent pages.
|
||||
|
||||
To solve these problems, the router provides us with a [`Link`] component we can
|
||||
use like this:
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus;
|
||||
# use dioxus::prelude::*;
|
||||
# extern crate dioxus_router;
|
||||
# use dioxus_router::prelude::*;
|
||||
fn SomeComponent(cx: Scope) -> Element {
|
||||
render! {
|
||||
Link {
|
||||
target: NavigationTarget::Internal(String::from("/some/path")),
|
||||
"Link text"
|
||||
}
|
||||
Link {
|
||||
target: "/some/path", // short form
|
||||
"Other link text"
|
||||
}
|
||||
}
|
||||
}
|
||||
{{#include ../../../examples/links.rs:nav}}
|
||||
```
|
||||
|
||||
The `target` in the example above is similar to the `href` of a regular anchor
|
||||
element. However, it tells the router more about what kind of navigation it
|
||||
should perform:
|
||||
should perform. It accepts something that can be converted into a
|
||||
[`NavigationTarget`]:
|
||||
|
||||
- The example uses [`Internal`]. We give it an arbitrary path that will be
|
||||
merged with the current URL.
|
||||
- [`Named`] allows us to navigate within our app using predefined names.
|
||||
See the chapter about [named navigation](./name.md) for more details.
|
||||
- [`External`] allows us to navigate to URLs outside of our app. See the
|
||||
chapter about [external navigation](./external.md) for more details.
|
||||
- The example uses a Internal route. This is the most common type of navigation.
|
||||
It tells the router to navigate to a page within our app by passing a variant of a [`Routable`] enum. This type of navigation can never fail if the link component is used inside a router component.
|
||||
- [`External`] allows us to navigate to URLs outside of our app. This is useful
|
||||
for links to external websites. NavigationTarget::External accepts an URL to navigate to. This type of navigation can fail if the URL is invalid.

# Named Navigation
|
||||
|
||||
When creating large applications, it can become difficult to keep track of all
|
||||
routes and how to navigate to them. It also can be hard to find all links to
|
||||
them, which makes it difficult to change paths.
|
||||
|
||||
To solve these problems, the router implements named navigation. When we define
|
||||
our routes we can give them arbitrary, unique names (completely independent from
|
||||
the path) and later ask the router to navigate to those names. The router will
|
||||
automatically create the actual path to navigate to, even inserting required
|
||||
parameters.
|
||||
|
||||
_Named_ navigation has a few advantages over _path-based_ navigation:
|
||||
|
||||
- Links can be created without knowing the actual path.
|
||||
- It is much easier to find all links to a specific route.
|
||||
- The router knows what links are invalid (and will panic in debug builds).
|
||||
|
||||
> When the router encounters an invalid link in a release build, it has to
|
||||
> handle that problem. You can hook into that process, to display a custom error
|
||||
> message. See the chapter about
|
||||
> [named navigation failures](../failures/named.md).
|
||||
|
||||
> The router will automatically define the name [`RootIndex`] to refer to the
|
||||
> root index route (`/`).
|
||||
>
|
||||
> It will also add other names (all of them are in the prelude module) in

fn Source(cx: Scope) -> Element {
|
||||
render! {
|
||||
Link {
|
||||
// instead of InternalTarget we use NamedTarget (via the `named` fn)
|
||||
// we can use the returned value to add parameters or a query
|
||||
target: named::<TargetName>().query("query"),
|
||||
"Go to target"
|
||||
}
|
||||
}
|

}
|

fn Target(cx: Scope) -> Element {

|
||||

## Check if a name is present
|
||||
|
||||
You can check if a specific name is present for the current route. This works
|
||||
similar to getting the value of a [parameter route](../routes/parameter.md) and
|
||||
the same restrictions apply.
|
||||

Sometimes we want our application to navigate to another page without having the
|
||||
user click on a link. This is called programmatic navigation.
|
||||
|
||||
## Acquiring a [`Navigator`]
|
||||
## Using a Navigator
|
||||
|
||||
To use programmatic navigation, we first have to acquire a [`Navigator`]. For
|
||||
that purpose we can use the [`use_navigate`] hook.
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus;
|
||||
use dioxus::prelude::*;
|

// ...
|
||||
# unimplemented!()
|
||||
}
|
||||
```
|
||||
|
||||
## Triggering a Navigation
|
||||
We can get a navigator with the [`use_navigator`] hook. This hook returns a [`Navigator`].
|
||||
|
||||
We can use the [`Navigator`] to trigger four different kinds of navigation:
|
||||
|
||||
- `push` will navigate to the target. It works like a regular anchor tag.
|
||||
- `replace` works like `push`, except that it replaces the current history entry
|
||||
instead of adding a new one. This means the prior page cannot be restored with
|
||||
the browsers back button.
|
||||
- `Go back` works like the browsers back button.
|
||||
- `Go forward` works like the browsers forward button (the opposite of the back
|
||||
button).
|
||||
instead of adding a new one. This means the prior page cannot be restored with the browser's back button.
|
||||
- `Go back` works like the browser's back button.
|
||||
- `Go forward` works like the browser's forward button.

You might have noticed that, like [`Link`], the [`Navigator`]s `push` and

`replace` functions take a [`NavigationTarget`]. This means we can use

[`Internal`], [`Named`] and [`External`].

# Outlets
|
||||
|
||||
[`Outlet`]s tell the router where to render content. In the following example
|
||||
the active routes content will be rendered within the [`Outlet`].
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus;
|
||||
# use dioxus::prelude::*;
|
||||
# extern crate dioxus_router;
|
||||
# use dioxus_router::prelude::*;
|
||||
# extern crate dioxus_ssr;
|
||||
|
||||
fn Index(cx: Scope) -> Element {
|
||||
render! {
|
||||
h1 { "Index" }
|
||||
}
|
||||
}
|
||||
|
||||
fn App(cx: Scope) -> Element {
|
||||
use_router(
|
||||
cx,
|
||||
&|| RouterConfiguration {
|
||||
# synchronous: true,
|
||||
..Default::default()
|
||||
},
|
||||
&|| Segment::content(comp(Index))
|
||||
);
|
||||
|
||||
render! {
|
||||
header { "header" }
|
||||
Outlet { }
|
||||
footer { "footer" }
|
||||
}
|
||||
}
|
||||
#
|
||||
# let mut vdom = VirtualDom::new(App);
|
||||
# vdom.rebuild();
|
||||
# let html = dioxus_ssr::render(&vdom);
|
||||
# assert_eq!(
|
||||
# html,
|
||||
# "<header>header</header><h1>Index</h1><footer>footer</footer>"
|
||||
# );
|
||||
```
|
||||
|
||||
The example above will output the following HTML (line breaks added for
|
||||
readability):
|
||||
|
||||
```html
|
||||
<header>header</header>
|
||||
<h1>Index</h1>
|
||||
<footer>footer</footer>
|
||||
```
|
||||
|
||||
## Nested Outlets
|
||||
|
||||
When using nested routes, we need to provide equally nested [`Outlet`]s.
|
||||
|
||||
> Learn more about [nested routes](./routes/nested.md) in their own chapter.
|
||||
|
||||
## Named Outlets
|
||||
|
||||
When building complex apps, we often need to display multiple pieces of content
|
||||
simultaneously. For example, we might have a sidebar that changes its content in
|
||||
sync with the main part of the page.
|
||||
|
||||
When defining our routes, we can use `RouteContentMulti` instead of
|
||||
`RouteContent::Component` (we've been using this through the `Into` trait) to
|
||||
tell the router about our content.
|
||||
|
||||
We then can use a named [`Outlet`] in our output, to tell the router where to
|
||||
put the side content.
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus;
|
||||
# use dioxus::prelude::*;
|
||||
# extern crate dioxus_router;
|
||||
# use dioxus_router::prelude::*;
|
||||
# extern crate dioxus_ssr;
|
||||
#
|
||||
|
||||
fn Main(cx: Scope) -> Element {
|
||||
render! {
|
||||
main { "Main Content" }
|
||||
}
|
||||
}
|
||||
|
||||
struct AsideName;
|
||||
fn Aside(cx: Scope) -> Element {
|
||||
render! {
|
||||
aside { "Side Content" }
|
||||
}
|
||||
}
|
||||
|
||||
fn App(cx: Scope) -> Element {
|
||||
use_router(
|
||||
cx,
|
||||
&|| RouterConfiguration {
|
||||
# synchronous: true,
|
||||
..Default::default()
|
||||
},
|
||||
&|| {
|
||||
Segment::content(
|
||||
multi(Some(comp(Main)))
|
||||
.add_named::<AsideName>(comp(Aside))
|
||||
)
|
||||
}
|
||||
);
|
||||
|
||||
render! {
|
||||
Outlet { }
|
||||
Outlet {
|
||||
name: Name::of::<AsideName>()
|
||||
}
|
||||
}
|
||||
}
|
||||
#
|
||||
# let mut vdom = VirtualDom::new(App);
|
||||
# vdom.rebuild();
|
||||
# let html = dioxus_ssr::render(&vdom);
|
||||
# assert_eq!(html, "<main>Main Content</main><aside>Side Content</aside>");
|
||||
```
|
||||
|
||||
The example above will output the following HTML (line breaks added for
|
||||
readability):
|
||||
|
||||
```html
|
||||
<main>Main Content</main>
|
||||
<aside>Side Content</aside>
|
||||
```
|
||||
|
||||
## Outlet depth override
|
||||
|
||||
When nesting [`Outlet`]s, they communicate with each other. This allows the
|
||||
nested [`Outlet`] to render the content of the nested route.
|
||||
|
||||
We can override the detected value. Be careful when doing so, it is incredibly
|
||||
easy to create an unterminated recursion. See below for an example of that.
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus;
|
||||
# use dioxus::prelude::*;
|
||||
# extern crate dioxus_router;
|
||||
# use dioxus_router::{history::MemoryHistory, prelude::*};
|
||||
# extern crate dioxus_ssr;
|
||||
#
|
||||
fn RootContent(cx: Scope) -> Element {
|
||||
render! {
|
||||
h1 { "Root" }
|
||||
Outlet { }
|
||||
}
|
||||
}
|
||||
|
||||
fn NestedContent(cx: Scope) -> Element {
|
||||
render! {
|
||||
h2 { "Nested" }
|
||||
}
|
||||
}
|
||||
|
||||
fn App(cx: Scope) -> Element {
|
||||
use_router(
|
||||
cx,
|
||||
&|| RouterConfiguration {
|
||||
# synchronous: true,
|
||||
# history: Box::new(MemoryHistory::with_initial_path("/root").unwrap()),
|
||||
..Default::default()
|
||||
},
|
||||
&|| {
|
||||
Segment::empty().fixed(
|
||||
"root",
|
||||
Route::content(comp(RootContent)).nested(
|
||||
Segment::content(comp(NestedContent))
|
||||
)
|
||||
)
|
||||
}
|
||||
);
|
||||
|
||||
render! {
|
||||
Outlet {
|
||||
depth: 1
|
||||
}
|
||||
}
|
||||
}
|
||||
#
|
||||
# let mut vdom = VirtualDom::new(App);
|
||||
# vdom.rebuild();
|
||||
# let html = dioxus_ssr::render(&vdom);
|
||||
# assert_eq!(html, "<h2>Nested</h2>");
|
||||
```
|
||||
|
||||
The example above will output the following HTML (line breaks added for
|
||||
readability):
|
||||
|
||||
```html
|
||||
<h2>Nested</h2>
|
||||
```
|
||||
|
||||
### Outlet recursion
|
||||
|
||||
This code will create a crash due to an unterminated recursion using
|
||||
[`Outlet`]s.
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus;
|
||||
# use dioxus::prelude::*;
|
||||
# extern crate dioxus_router;
|
||||
# use dioxus_router::prelude::*;
|
||||
#
|
||||
fn Content(cx: Scope) -> Element {
|
||||
render! {
|
||||
h1 { "Heyho!" }
|
||||
Outlet {
|
||||
depth: 0,
|
||||
}
|
||||
}
|
||||
}
|
||||
|
||||
fn App(cx: Scope) -> Element {
|
||||
use_router(cx, &Default::default, &|| Segment::content(comp(Content)));
|
||||
|
||||
render! {
|
||||
Outlet { }
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
The [`Outlet`] in the `App` component has no parent [`Outlet`], so its depth
|
||||
will be `0`. When rendering for the path `/`, it therefore will render the
|
||||
`Content` component.
|
||||
|
||||
The `Content` component will render an `h1` and an [`Outlet`]. That [`OUtlet`]
|
||||
would usually have a depth of `1`, since it is a descendant of the [`Outlet`] in
|
||||
the `App` component. However, we override its depth to `0`, so it will render
|
||||
the `Content` component.
|
||||
|
||||
That means the `Content` component will recurse until someone (e.g. the OS) puts
|
||||
a stop to it.

# Query
|
||||
|
||||
Some apps use the query part of the URL to encode information. The router allows
|
||||
you to easily access the query, as well as set it when navigating.
|
||||
|
||||
## Accessing the query
|
||||
|
||||
The [`use_route`] hook allows us to access the current query in two ways. The
|
||||
returned `struct` contains a `query` field, that contains the query (without the
|
||||
leading `?`).
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus;
|
||||
use dioxus::prelude::*;
|
||||
# extern crate dioxus_router;
|
||||
use dioxus_router::prelude::*;
|
||||
|
||||
fn SomeComponent(cx: Scope) -> Element {
|
||||
let route = use_route(cx).expect("nested in Router");
|
||||
|
||||
let query = route.query.clone().unwrap();
|
||||
|
||||
// ...
|
||||
# unimplemented!()
|
||||
}
|
||||
```
|
||||
|
||||
## Setting the query
|
||||
|
||||
When navigating we can tell the router to change the query. However, the method
|
||||
we use to do this is very different, depending on how we specify our target.
|
||||
|
||||
### [`Internal`] and [`External`]
|
||||
|
||||
When using [`Internal`] or [`External`] we have to append our query manually.
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus;
|
||||
# use dioxus::prelude::*;
|
||||
# extern crate dioxus_router;
|
||||
# use dioxus_router::prelude::*;
|
||||
#
|
||||
fn SomeComponent(cx: Scope) -> Element {
|
||||
render! {
|
||||
Link {
|
||||
target: NavigationTarget::Internal("/some/path?query=yes".into()),
|
||||
"Internal target"
|
||||
}
|
||||
Link {
|
||||
target: NavigationTarget::External("https://dioxuslab.com?query=yes".into()),
|
||||
"External target"
|
||||
}
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### [`Named`]
|
||||
|
||||
When using [named navigation](./navigation/name.md) we can pass the query via
|
||||
a function.
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus;
|
||||
# use dioxus::prelude::*;
|

||||
# use dioxus_router::prelude::*;
|
||||
# struct Target;
|
||||
#
|
||||
fn SomeComponent(cx: Scope) -> Element {
|
||||
render! {
|
||||
Link {
|
||||
target: named::<Target>().query("query=yes"),
|
||||
"Query String"
|
||||
}
|
||||
Link {
|
||||
target: named::<Target>().query(vec![("query", "yes")]),
|
||||
"Query Vec"
|
||||
}
|
||||
}
|
||||
}

# Redirects
|
||||
|
||||
In some cases, we may want to redirect our users to another page whenever they
|
||||
open a specific path. We can tell the router to do this with the `#[redirect]`
|
||||
attribute.
|
||||
|
||||
The `#[redirect]` attribute accepts a route and a closure with all of the parameters defined in the route. The closure must return a [`NavigationTarget`].
|
||||

# Catch All Routes
|
||||
|
||||
Many modern web apps store parameters within their current path. This allows
|
||||
users to share URLs that link to a specific bit of content. We can create this
|
||||
functionality with catch all routes.
|
||||
|
||||
> If you want to change what route is active based on the format of the
|
||||
> parameter, see [Matching Routes](./matching.md).
|
||||
|
||||
> The parameter will be URL decoded.
|
||||
|
||||
## Creating a content component
|
||||
|
||||
We start by creating a component that uses the parameters value.
|
||||
|
||||
We can get the current state of the router using the [`use_route`] hook. From
|
||||
that state we can extract the current value of our parameter by using a key we
|
||||
will later also define on our route.
|
||||
|
||||
> It is **VERY IMPORTANT** to drop the object returned by the [`use_route`]
|
||||
> hook once our component finished rendering. Otherwise the entire router will
|
||||
> be frozen.
|
||||
|
||||
> The [`use_route`] hook can only be used in components nested within a
|
||||
> component that called [`use_router`].
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus;
|
||||
use dioxus::prelude::*;
|
||||
# extern crate dioxus_router;
|
||||
use dioxus_router::prelude::*;
|
||||
|
||||
struct Name;
|
||||
|
||||
fn Greeting(cx: Scope) -> Element {
|
||||
let route = use_route(cx).expect("is nested within a Router component");
|
||||
let name = route.parameter::<Name>()
|
||||
.map(|name| name.clone())
|
||||
.unwrap_or(String::from("world"));
|
||||
|
||||
render! {
|
||||
p { "Hello, {name}!" }
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
## Defining the routes
|
||||
|
||||
Now we can define our route. Unlike a fixed [`Route`], a [`ParameterRoute`]
|
||||
needs two arguments to be created.
|
||||
|
||||
> Also note that each [`Segment`] can have exactly one parameter or
|
||||
> [fallback route](./fallback.md).
|
||||
>
|
||||
> For that reason, the example below would not work in practice, but showing
|
||||
> both forms (explicit and short) is more important for this example.
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus;
|
||||
# use dioxus::prelude::*;
|
||||
# extern crate dioxus_router;
|
||||
# use dioxus_router::prelude::*;
|
||||
# fn Greeting(cx: Scope) -> Element { unimplemented!() }
|
||||
#
|
||||
struct Name;
|
||||
|
||||
fn App(cx: Scope) -> Element {
|
||||
use_router(
|
||||
cx,
|
||||
&|| RouterConfiguration {
|
||||
..Default::default()
|
||||
},
|
||||
&|| {
|
||||
Segment::empty()
|
||||
.catch_all(ParameterRoute::content::<Name>(comp(Greeting)))
|
||||
.catch_all((comp(Greeting), Name { })) // same in short
|
||||
}
|
||||
);
|
||||
|
||||
// ...
|
||||
# unimplemented!()
|
||||
}
|
||||
```
|
||||
|
||||
## Interaction with other routes
|
||||
|
||||
Each individual [`Segment`] can only ever have one active route. This means that
|
||||
when a [`Segment`] has more than just a catch all route, the router has to
|
||||
decide which is active. It does that this way:
|
||||
|
||||
0. If the segment is not specified (i.e. `/`), then the index route will be
|
||||
active.
|
||||
1. If a [_fixed_](./index.md#fixed-routes) route matches the current path, it
|
||||
will be active.
|
||||
2. If a [_matching_ route](./matching.md) matches the current path, it will be
|
||||
active. _Matching_ routes are checked in the order they are defined.
|
||||
3. If neither a _fixed_ nor a _matching_ route is active, the _catch all_ route
|
||||
or [_fallback_ route](./fallback.md) will be.
|
||||
|
||||
Step 0 means that if we want a parameter to be empty, that needs to be specified
|
||||
by the path, i.e. `//`.
|
||||
|
||||
> Be careful with using catch all routes on the root [`Segment`]. Navigating to
|
||||
> paths starting with `//` will **NOT** work. This is not a limitation of the
|
||||
> router, but rather of how relative URLs work.
|
||||
>
|
||||
> If you absolutely need an empty parameter on the root [`Segment`], a URL like
|
||||
> this _could_ work:
|
||||
>
|
||||

# Fallback Routes
|
||||
|
||||
Sometimes the router might be unable to find a route for the provided path. We
|
||||
might want it to show a prepared error message to our users in that case.
|
||||
Fallback routes allow us to do that.
|
||||
|
||||
> This is especially important for use cases where users can manually change the
|
||||
> path, like web apps running in the browser.
|
||||
|
||||
## A single global fallback
|
||||
|
||||
To catch all cases of invalid paths within our app, we can simply add a fallback
|
||||
route to our root [`Segment`].
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus;
|
||||
use dioxus::prelude::*;
|
||||
# extern crate dioxus_router;
|
||||
use dioxus_router::{history::MemoryHistory, prelude::*};
|
||||
# extern crate dioxus_ssr;
|
||||
|
||||
fn Index(cx: Scope) -> Element {
|
||||
render! {
|
||||
h1 { "Index" }
|
||||
}
|
||||
}
|
||||
|
||||
fn Fallback(cx: Scope) -> Element {
|
||||
render! {
|
||||
h1 { "Error 404 - Not Found" }
|
||||
p { "The page you asked for doesn't exist." }
|
||||
}
|
||||
}
|
||||
|
||||
fn App(cx: Scope) -> Element {
|
||||
use_router(
|
||||
cx,
|
||||
&|| RouterConfiguration {
|
||||
# synchronous: true,
|
||||
# history: Box::new(MemoryHistory::with_initial_path("/invalid").unwrap()),
|
||||
..Default::default()
|
||||
},
|
||||
&|| {
|
||||
Segment::content(comp(Index)).fallback(comp(Fallback))
|
||||
}
|
||||
);
|
||||
|
||||
render! {
|
||||
Outlet { }
|
||||
}
|
||||
}
|
||||
#
|
||||
# let mut vdom = VirtualDom::new(App);
|
||||
# vdom.rebuild();
|
||||
# assert_eq!(
|
||||
# dioxus_ssr::render(&vdom),
|
||||
# "<h1>Error 404 - Not Found</h1><p>The page you asked for doesn't exist.</p>"
|
||||
# );
|
||||
```
|
||||
|
||||
## More specific fallback routes
|
||||
|
||||
In some cases we might want to show different fallback content depending on what
|
||||
section of our app the user is in.
|
||||
|
||||
For example, our app might have several settings pages under `/settings`, such
|
||||
as the password settings `/settings/password` or the privacy settings
|
||||
`/settings/privacy`. When our user is in the settings section, we want to show
|
||||
them _"settings not found"_ instead of _"page not found"_.
|
||||
|
||||
We can easily do that by setting a fallback route on our nested [`Segment`]. It
|
||||
will then replace the global fallback whenever our [`Segment`] was active.
|
||||
|
||||
Note the `.clear_fallback(false)` part. If we didn't add this, the fallback
|
||||
content would be rendered inside the `Settings` component.
|
||||
|
||||

# Defining Routes
|
||||
|
||||
When creating a router we need to pass it a [`Segment`]. It tells the router
|
||||
about all the routes of our app.
|
||||
When creating a [`Routable`] enum, we can define routes for our application using the `route("path")` attribute.
|
||||
|
||||
## Example content
|
||||
## Route Segments
|
||||
|
||||
To get a good understanding of how we define routes we first need to prepare
|
||||
some example content, so we can see the routing in action.
|
||||
Each route is made up of segments. Most segments are separated by `/` characters in the path.
|
||||
|
||||
There are four fundamental types of segments:
|
||||
|
||||
1. [Static segments](#static-segments) are fixed strings that must be present in the path.
|
||||
2. [Dynamic segments](#dynamic-segments) are types that can be parsed from a segment.
|
||||
3. [Catch-all segments](#catch-all-segments) are types that can be parsed from multiple segments.
|
||||
4. [Query segments](#query-segments) are types that can be parsed from the query string.
|
||||
|
||||
Routes are matched:
|
||||
|
||||
- First, from most specific to least specific (Static then Dynamic then Catch All) (Query is always matched)
|
||||
- Then, if multiple routes match the same path, the order in which they are defined in the enum is followed.
|
||||
|
||||
## Static segments
|
||||
|
||||
Fixed routes match a specific path. For example, the route `#[route("/about")]` will match the path `/about`.
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus;
|
||||
use dioxus::prelude::*;
|
||||
# extern crate dioxus_router;
|
||||
use dioxus_router::prelude::*;
|
||||
|
||||
fn Index(cx: Scope) -> Element {
|
||||
render! {
|
||||
h1 { "Welcome to our test site!" }
|
||||
}
|
||||
}
|
||||
|
||||
fn Other(cx: Scope) -> Element {
|
||||
render! {
|
||||
p { "some other content" }
|
||||
}
|
||||
}
|
||||
{{#include ../../../examples/static_segments.rs:route}}
|
||||
```
|
||||
|
||||
## Index routes
|
||||
## Dynamic Segments
|
||||
|
||||
The easiest thing to do is to define an index route.
|
||||
Dynamic segments are in the form of `:name` where `name` is
|
||||
the name of the field in the route variant. If the segment is parsed
|
||||
successfully then the route matches, otherwise the matching continues.
|
||||
|
||||
Index routes act very similar to `index.html` files in most web servers. They
|
||||
are active, when we don't specify a route.
|
||||
|
||||
> Note that we wrap our `Index` component with [`comp`]. This is because of
|
||||
> rust type system requirements.
|
||||
The segment can be of any type that implements `FromStr`.
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus;
|
||||
# use dioxus::prelude::*;
|
||||
# extern crate dioxus_router;
|
||||
# use dioxus_router::prelude::*;
|
||||
# fn Index(cx: Scope) -> Element { unimplemented!() }
|
||||
#
|
||||
fn App(cx: Scope) -> Element {
|
||||
use_router(
|
||||
cx,
|
||||
&|| RouterConfiguration {
|
||||
..Default::default()
|
||||
},
|
||||
&|| Segment::content(comp(Index))
|
||||
);
|
||||
|
||||
// ...
|
||||
# unimplemented!()
|
||||
}
|
||||
{{#include ../../../examples/dynamic_segments.rs:route}}
|
||||
```
|
||||
|
||||
## Fixed routes
|
||||
## Catch All Segments
|
||||
|
||||
It is almost as easy to define a fixed route.
|
||||
Catch All segments are in the form of `:...name` where `name` is the name of the field in the route variant. If the segments are parsed successfully then the route matches, otherwise the matching continues.
|
||||
|
||||
Fixed routes work similar to how web servers treat files. They are active, when
|
||||
specified in the path. In the example, the path must be `/other`.
|
||||
The segment can be of any type that implements `FromSegments`. (Vec<String> implements this by default)
|
||||
|
||||
> The path will be URL decoded before checking if it matches our route.
|
||||
Catch All segments must be the _last route segment_ in the path (query segments are not counted) and cannot be included in nests.
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus;
|
||||
# use dioxus::prelude::*;
|
||||
# extern crate dioxus_router;
|
||||
# use dioxus_router::prelude::*;
|
||||
# fn Index(cx: Scope) -> Element { unimplemented!() }
|
||||
# fn Other(cx: Scope) -> Element { unimplemented!() }
|
||||
#
|
||||
fn App(cx: Scope) -> Element {
|
||||
use_router(
|
||||
cx,
|
||||
&|| RouterConfiguration {
|
||||
..Default::default()
|
||||
},
|
||||
&|| Segment::content(comp(Index)).fixed("other", comp(Other))
|
||||
// ^ note the absence of a / prefix
|
||||
);
|
||||
|
||||
// ...
|
||||
# unimplemented!()
|
||||
}
|
||||
{{#include ../../../examples/catch_all_segments.rs:route}}
|
||||
```
|
||||
|
||||
## Full Code
|
||||
## Query Segments
|
||||
|
||||
Query segments are in the form of `?:name` where `name` is the name of the field in the route variant.
|
||||
|
||||
Unlike [Dynamic Segments](#dynamic-segments) and [Catch All Segments](#catch-all-segments), parsing a Query segment must not fail.
|
||||
|
||||
The segment can be of any type that implements `FromQuery`.
|
||||
|
||||
Query segments must be the _after all route segments_ and cannot be included in nests.

||||

||||
```rust, no_run

When accepting parameters via the path, some complex applications might need to
|
||||
decide what route should be active based on the format of that parameter.
|
||||
_Matching_ routes make it easy to implement such behavior.

||||

||||

|
||||

## Matcher

In the example above, both _matching routes_ use a regular expression to specify

when they match. However, _matching routes_ are not limited to those. They
|
||||
accept all types that implement the [`Matcher`] trait.
|
||||
|
||||
For example, you could (but probably shouldn't) implement a matcher, that
|
||||
matches all values with an even number of characters:
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus_router;
|
||||
# use dioxus_router::prelude::*;

#[derive(Debug)]
|
||||
struct EvenMatcher;
|
||||
|
||||
impl Matcher for EvenMatcher {
|
||||
fn matches(&self, value: &str) -> bool {
|
||||
value.len() % 2 == 0
|

}

}

# Multiple Components & Redirects
|
||||
|
||||
## Multiple Components
|
||||
|
||||
When creating complex apps we sometimes want to have multiple pieces of content
|
||||
side by side. The router allows us to do this. For more details see the section
|
||||
about [named `Outlet`s](../outlets.md#named-outlets).
|
||||
|
||||
## Redirects
|
||||
|
||||
In some cases we may want to redirect our users to another page whenever they
|
||||
open a specific path. We can tell the router to do this when defining our
|
||||
routes.
|
||||
|
||||
> Redirects to external pages only work in certain conditions. For more details
|
||||
> see the chapter about [external navigation failures](../failures/external.md).
|
||||
|
||||
In the following example we will redirect everybody from `/` and `/start` to
|
||||
`/home`.

Nested routes allow us to do this without repeating /settings in every route.
|

|
||||
## Route Depth
|
||||
## Nesting
|
||||
|
||||
With nesting routes, the router manages content on multiple levels. In our
|
||||
example, when the path is `/settings`, there are two levels of content:
|
||||
To nest routes, we use the `#[nest("path")]` and `#[end_nest]` attributes.
|
||||
|
||||
0. The `Settings` component
|
||||
1. The `GeneralSettings` component
|
||||
The path in nest must not:
|
||||
|
||||
Dioxus Router uses the [`Outlet`] component to actually render content, but each
|
||||
[`Outlet`] can only render content from one level. This means that for the
|
||||
content of nested routes to actually be rendered, we also need nested
|
||||
[`Outlet`]s.
|
||||
1. Contain a [Catch All Segment](index.md#catch-all-segments)
|
||||
2. Contain a [Query Segment](index.md#query-segments)
|
||||
|
||||
## Defining the content components
|
||||
If you define a dynamic segment in a nest, it will be available to all child routes and layouts.
|
||||
|
||||
We start by creating the components we want the router to render.
|
||||
|
||||
Take a look at the `Settings` component. When it gets rendered by an [`Outlet`],
|
||||
it will render a second [`Outlet`]. Thus the second [`Outlet`] is nested within
|
||||
the first one, and will in turn render our nested content.
|
||||
To finish a nest, we use the `#[end_nest]` attribute or the end of the enum.
|
||||

||||

||||
# // Hidden lines (like this one) make the documentation tests work.

fn Settings(cx: Scope) -> Element {

render! {

h1 { "Settings" }

Outlet { }

||||
}
|

}
|

}

{{#include ../../../examples/nest.rs:route}}
|
||||
```
|
||||
|
||||
## Defining the root [`Segment`]
|
||||
|
||||
Now we create the [`Segment`] that we will pass to the router.
|
||||
|
||||
Note that we wrap `comp(Settings)` within a [`Route`]. For this exact code that
|
||||
is unnecessary, as this would be done automatically. However, in the next step
|
||||
we'll use a method of [`Route`], so we might as well add this now.

|
||||
}
|
||||
```
|
||||
|
||||
## Defining the nested [`Segment`]
|
||||
|
||||
In order to create nested routes we need to create a nested [`Segment`]. We then
|
||||
pass it to the [`Route`] on the root segment.
|
||||
|
||||
> A [`Segment`] always refers to one exact segment of the path.

```
|

|
||||
## Modifying the app to make using sitemaps easier
|
||||
|
||||
Preparing our app for sitemap generation is quite easy. We just need to extract
|
||||
our segment definition into its own function.
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus;
|
||||
# use dioxus::prelude::*;
|
||||
# extern crate dioxus_router;
|
||||
# use dioxus_router::prelude::*;
|
||||
# extern crate dioxus_ssr;
|
||||
# fn Home(cx: Scope) -> Element { unimplemented!() }
|
||||
# fn Fixed(cx: Scope) -> Element { unimplemented!() }
|
||||
# fn Nested(cx: Scope) -> Element { unimplemented!() }
|
||||
# struct ParameterName;
|
||||
# fn Parameter(cx: Scope) -> Element { unimplemented!() }
|
||||
#
|
||||
fn App(cx: Scope) -> Element {
|
||||
use_router(
|
||||
cx,
|
||||
&|| RouterConfiguration {
|
||||
..Default::default()
|
||||
},
|
||||
&prepare_routes
|
||||
);
|
||||
|
||||
render! {
|
||||
Outlet { }
|
||||
}
|
||||
}
|
||||
|
||||
fn prepare_routes() -> Segment<Component> {
|
||||
Segment::content(comp(Home))
|
||||
.fixed(
|
||||
"fixed",
|
||||
Route::content(comp(Fixed)).nested(
|
||||
Segment::empty().fixed("nested", comp(Nested))
|
||||
)
|
||||
)
|
||||
.catch_all((comp(Parameter), ParameterName { }))
|
||||
}
|
||||
```
|
||||
|
||||
## Sitemaps with parameter names
|
||||
|
||||
The first variant to generate sitemaps is very simple. It finds all routes
|
||||
within the [`Segment`] and adds them to the returned `Vec`.
|
||||
|
||||
Matching and parameter routes are represented by their `key`, prefixed with `\`.
|
||||
Besides that `\`, all paths are URL encoded.
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
# extern crate dioxus;
|
||||
# use dioxus::prelude::*;
|
||||
# extern crate dioxus_router;
|
||||
# use dioxus_router::prelude::*;
|
||||
# extern crate dioxus_ssr;
|
||||
# fn Home(cx: Scope) -> Element { unimplemented!() }
|
||||
# fn Fixed(cx: Scope) -> Element { unimplemented!() }
|
||||
# fn Nested(cx: Scope) -> Element { unimplemented!() }
|
||||
# struct ParameterName;
|
||||
# fn Parameter(cx: Scope) -> Element { unimplemented!() }
|
||||
# fn prepare_routes() -> Segment<Component> {
|
||||
# Segment::content(comp(Home))
|
||||
# .fixed(
|
||||
# "fixed",
|
||||
# Route::content(comp(Fixed)).nested(
|
||||
# Segment::empty().fixed("nested", comp(Nested))
|
||||
# )
|
||||
# )
|
||||
# .catch_all((comp(Parameter), ParameterName { }))
|
||||
# }
|
||||
|
||||
let expected = vec![
|
||||
"/",
|
||||
"/fixed",
|
||||
"/fixed/nested",
|
||||
// Usually, here would be a fourth result representing the parameter route.
|
||||
// However, due to mdbook the name for this file would constantly change,
|
||||
// which is why we cannot show it. It would look something like this:
|
||||
// "/\\your_crate::ParameterName",
|
||||
];
|
||||
let mut sitemap = prepare_routes().gen_sitemap();
|
||||
sitemap.remove(3); // see above
|
||||
assert_eq!(sitemap, expected);
|
||||
```
|
||||
|
||||
## Sitemaps with actual parameter values
|
||||
|
||||
The second variant to generate sitemaps is a bit more involved. When it
|
||||
encounters a parameter route, it inserts all values with a matching `key` that
|
||||
were provided to it.
|
||||
|
||||
Matching routes only add their path if the value matches their regex.
|
||||
|
||||
All paths are URL encoded.
|
||||
|
||||
```rust, no_run
|
||||
# // Hidden lines (like this one) make the documentation tests work.
|
||||
use std::collections::{BTreeMap, HashSet};
|
||||
# extern crate dioxus;
|
||||
# use dioxus::prelude::*;
|
||||
# extern crate dioxus_router;
|
||||
# use dioxus_router::prelude::*;
|
||||
# extern crate dioxus_ssr;
|
||||
# fn Home(cx: Scope) -> Element { unimplemented!() }
|
||||
# fn Fixed(cx: Scope) -> Element { unimplemented!() }
|
||||
# fn Nested(cx: Scope) -> Element { unimplemented!() }
|
||||
# struct ParameterName;
|
||||
# fn Parameter(cx: Scope) -> Element { unimplemented!() }
|
||||
# fn prepare_routes() -> Segment<Component> {
|
||||
# Segment::content(comp(Home))
|
||||
# .fixed(
|
||||
# "fixed",
|
||||
# Route::content(comp(Fixed)).nested(
|
||||
# Segment::empty().fixed("nested", comp(Nested))
|
||||
# )
|
||||
# )
|
||||
# .catch_all((comp(Parameter), ParameterName { }))
|
||||
# }
|
||||
|
||||
let parameters = {
|
||||
let mut parameters = BTreeMap::new();
|
||||
|
||||
parameters.insert(
|
||||
Name::of::<ParameterName>(),
|
||||
vec![
|
||||
String::from("some-parameter-value"),
|
||||
String::from("other-parameter-value")
|
||||
]
|
||||
);
|
||||
|
||||
parameters
|
||||
};
|
||||
|
||||
let expected: Vec<String> = vec![
|
||||
"/",
|
||||
"/fixed",
|
||||
"/fixed/nested",
|
||||
"/some-parameter-value",
|
||||
"/other-parameter-value",
|
||||
].into_iter().map(String::from).collect();
|
||||
assert_eq!(expected, prepare_routes().gen_parameter_sitemap(¶meters));
|

# Static Generation
|
||||
|
||||
## Getting the Sitemap
|
||||
|
||||
The [`Routable`] trait includes an associated [`SITE_MAP`] constant that contains the map of all of the routes in the enum.
|
||||
|
||||
By default, the sitemap is a tree of (static or dynamic) RouteTypes, but it can be flattened into a list of individual routes with the `.flatten()` method.
|
||||
|
||||
## Generating a Sitemap
|
||||
|
||||
To statically render pages, we need to flatten the route tree and generate a file for each route that contains only static segments:
|
||||
|
||||
```rust, no_run
|
||||
{{#include ../../../../packages/router/examples/static_generation.rs}}
|
||||
```
