<blockquote>
|
||||
<p>This section doesn't apply when specifying a <code>target</code> on a <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Link.html"><code>Link</code></a>. See the
|
||||
chapter about <a href="../navigation/external.html">external navigation</a> for more
|
||||
details.</p>
|
||||
</blockquote>
|
||||
<p>When we ask the router to navigate to an external target, either through
|
||||
<a href="../navigation/programmatic.html">programmatic navigation</a> or a
|
||||
<a href="../routes/multiple-and-redirect.html#redirects">redirect</a> the router needs to
|
||||
navigate to an external target without being able to rely on an anchor element.</p>
|
||||
<p>This will only work in the browser, when using either <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/history/struct.WebHistory.html"><code>WebHistory</code></a> or
|
||||
<a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/history/struct.WebHashHistory.html"><code>WebHashHistory</code></a>.</p>
|
||||
<h2 id="failure-handling"><a class="header" href="#failure-handling">Failure handling</a></h2>
|
||||
<p>When the router encounters an external navigation it cannot fulfill, it changes
|
||||
the path to <code>/</code> and shows some fallback content.</p>
|
||||
<blockquote>
|
||||
<p>You can detect if the router is in the external navigation failure handling
|
||||
state by <a href="../navigation/name.html#check-if-a-name-is-present">checking</a> if the
|
||||
<a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/prelude/struct.FailureExternalNavigation.html"><code>FailureExternalNavigation</code></a> name is present.</p>
|
||||
</blockquote>
|
||||
<p>The default fallback explains to the user that the navigation was unsuccessful
|
||||
and provides them with a <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Link.html"><code>Link</code></a> to fulfill it manually. It also allows them to
|
||||
go back to the previous page.</p>
|
||||
<p>You can override it by setting the <code>failure_external_navigation</code> value of the
|
||||
<a href="https://docs.rs/dioxus-router/latest/dioxus_router/hooks/struct.RouterConfiguration.html"><code>RouterConfiguration</code></a>. The external URL will be provided via the
|
||||
<a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/prelude/struct.FailureExternalNavigation.html"><code>FailureExternalNavigation</code></a> parameter.</p>

|
||||
<p>When using <a href="../navigation/name.html">named navigation</a>, the router runs into a
|
||||
problem under these circumstances:</p>
|
||||
<ol>
|
||||
<li>The name we try to navigate to is not contained within our routes.</li>
|
||||
<li>The route we navigate to requires a parameter that we don't provide when
|
||||
triggering the navigation.</li>
|
||||
</ol>
|
||||
<blockquote>
|
||||
<p>Users cannot directly interact with named navigation. If a named navigation
|
||||
failure occurs, your app (or the router) has a bug.</p>
|
||||
</blockquote>
|
||||
<p>The router reacts to this problem differently, depending on our apps build kind.</p>
|
||||
<h2 id="debug"><a class="header" href="#debug">Debug</a></h2>
|
||||
<p>When running a debug build, the router will <code>panic</code> whenever it encounters an
|
||||
invalid navigation. This ensures that we notice these problems when we are
|
||||
testing our application.</p>
|
||||
<h2 id="release"><a class="header" href="#release">Release</a></h2>
|
||||
<p>When running a release build, the router can't just <code>panic</code>, as that would be a
|
||||
horrible user experience. Instead, it changes to show some fallback content.</p>
|
||||
<blockquote>
|
||||
<p>You can detect if the router is in the named navigation failure handling state
|
||||
by <a href="../navigation/name.html#check-if-a-name-is-present">checking</a> if the
|
||||
<a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/prelude/struct.FailureNamedNavigation.html"><code>FailureNamedNavigation</code></a> name is present.</p>
|
||||
</blockquote>
|
||||
<p>The default fallback explains to the user that an error occurred and asks them
|
||||
to report the bug to the app developer.</p>
|
||||
<p>You can override it by setting the <code>failure_named_navigation</code> value of the
|
||||
<a href="https://docs.rs/dioxus-router/latest/dioxus_router/hooks/struct.RouterConfiguration.html"><code>RouterConfiguration</code></a>.</p>

|
||||
<p>The router enforces a limit of 25 redirects during a single routing navigation.
|
||||
This is done to prevent infinite loops. If your app breaches that limit, you
|
||||
should reorganize its routes to reduce the number of redirects.</p>
|
||||
<blockquote>
|
||||
<p>Users cannot trigger a redirection. If the redirection limit is breached, your
|
||||
app (or the router) has a bug.</p>
|
||||
</blockquote>
|
||||
<blockquote>
|
||||
<p>The <a href="../routing-update-callback.html"><code>on_update</code></a> callback doesn't count
|
||||
towards the limit, and resets it. You may have 25 redirects, then add an other
|
||||
one via the callback, and then have another 25.</p>
|
||||
</blockquote>
|
||||
<p>The router reacts to a breach differently, depending on our apps build kind.</p>
|
||||
<h2 id="debug"><a class="header" href="#debug">Debug</a></h2>
|
||||
<p>When running a debug build, the router will <code>panic</code> whenever the redirecion
|
||||
limit is breached. This ensures that we notice these problems when we are
|
||||
testing our application.</p>
|
||||
<h2 id="release"><a class="header" href="#release">Release</a></h2>
|
||||
<p>When running a release build, the router can't just <code>panic</code>, as that would be a
|
||||
horrible user experience. Instead, it changes to show some fallback content.</p>
|
||||
<blockquote>
|
||||
<p>You can detect if the router is in the redirection limit failure handling
|
||||
state by <a href="../navigation/name.html#check-if-a-name-is-present">checking</a> if the
|
||||
<a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/prelude/struct.FailureRedirectionLimit.html"><code>FailureRedirectionLimit</code></a> name is present.</p>
|
||||
</blockquote>
|
||||
<p>The default fallback explains to the user that an error occurred and asks them
|
||||
to report the bug to the app developer.</p>
|
||||
<p>You can override it by setting the <code>failure_redirection_limit</code> value of the
|
||||
<a href="https://docs.rs/dioxus-router/latest/dioxus_router/hooks/struct.RouterConfiguration.html"><code>RouterConfiguration</code></a>.</p>

|
||||
<p>Some platforms, like web browsers, provide users with an easy way to navigate
|
||||
through an apps history. They have UI elements or integrate with the OS.</p>
|
||||
<p>However, native platforms usually don't provide such amenities, which means that
|
||||
apps wanting users to have access to them, need to implement them. For this
|
||||
reason the router comes with two components, which emulate a browsers back and
|
||||
forward buttons:</p>
|
||||
<ul>
|
||||
<li><a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.GoBackButton.html"><code>GoBackButton</code></a></li>
|
||||
<li><a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.GoForwardButton.html"><code>GoForwardButton</code></a></li>
|
||||
</ul>
|
||||
<blockquote>
|
||||
<p>If you want to navigate through the history programmatically, take a look at
|
||||
<a href="./navigation/programmatic.html"><code>programmatic navigation</code></a>.</p>
|
||||
</blockquote>
|
||||
<pre><pre class="playground"><code class="language-rust no_run edition2021">
|
||||
<span class="boring">#![allow(unused)]
|
||||
</span><span class="boring">fn main() {
|
||||
</span><span class="boring">// Hidden lines (like this one) make the documentation tests work.
|
||||

GoBackButton {

|
||||
}
|
||||
GoForwardButton {

|
||||
}
|
||||
}
|
||||
}
|
||||
<span class="boring">}
|
||||
</span></code></pre></pre>
|
||||
<p>As you might know, browsers usually disable the back and forward buttons if
|
||||
there is no history to navigate to. The routers history buttons try to do that
|
||||
too, but depending on the <a href="./history-providers.html">history provider</a> that might not be possible.</p>
|
||||
<p>Importantly, neither <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/history/struct.WebHistory.html"><code>WebHistory</code></a> nor <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/history/struct.WebHashHistory.html"><code>WebHashHistory</code></a> support that feature.
|
||||
This is due to limitations of the browser History API.</p>
|
||||
<p>However, in both cases the router will just ignore button presses, if there is
|
||||
no history to navigate to.</p>
|
||||
<p>Also, when using <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/history/struct.WebHistory.html"><code>WebHistory</code></a> or <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/history/struct.WebHashHistory.html"><code>WebHashHistory</code></a>, the history buttons might
|
||||
navigate a user to a history entry outside your app.</p>

|
||||
<p>In order to provide the ability to traverse the navigation history, the router
|
||||
uses <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/history/trait.HistoryProvider.html"><code>HistoryProvider</code></a>s. Those implement the actual back-and-forth
|
||||
functionality.</p>
|
||||
<p>The router provides five <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/history/trait.HistoryProvider.html"><code>HistoryProvider</code></a>s, but you can also create your own.
|
||||
The five default implementations are:</p>
|
||||
<ul>
|
||||
<li>The <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/history/struct.MemoryHistory.html"><code>MemoryHistory</code></a> is a custom implementation that works in memory.</li>
|
||||
<li>The <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/history/struct.WebHistory.html"><code>WebHistory</code></a> integrates with the browsers URL.</li>
|
||||
<li>The <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/history/struct.WebHashHistory.html"><code>WebHashHistory</code></a> also integrates with the browser, but uses the fragment
|
||||
part of the URL.</li>
|
||||
</ul>
|
||||
<p>By default the router uses the <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/history/struct.MemoryHistory.html"><code>MemoryHistory</code></a>. It might be changed to use
|
||||
<a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/history/struct.WebHistory.html"><code>WebHistory</code></a> when the <code>web</code> feature is active, but that is not guaranteed.</p>
|
||||
<p>You can override the default history:</p>

<p>In this chapter we will learn how to add the router to our app. By it self, this
|
||||
is not very useful. However, it is a prerequisite for all the functionality
|
||||
described in the other chapters.</p>
|
||||
<blockquote>
|
||||
<p>Make sure you added the <code>dioxus-router</code> dependency as explained in the
|
||||
<a href="../index.html">introduction</a>.</p>
|
||||
</blockquote>
|
||||
<p>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. We
|
||||
add it by using the <a href="https://docs.rs/dioxus-router/latest/dioxus_router/hooks/fn.use_router.html"><code>use_router</code></a> hook</p>

|

<p>In modern apps, and especially on the web, we often want to send our users to an
|
||||
other website. <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/navigation/enum.NavigationTarget.html#variant.External"><code>External</code></a> allows us to make a <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Link.html"><code>Link</code></a> navigate to an
|
||||
external page.</p>
|
||||
<blockquote>
|
||||
<p>You might already now about
|
||||
<a href="../failures/external.html">external navigation failures</a>. The <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Link.html"><code>Link</code></a>
|
||||
component doesn't rely on the code path where those originate. Therefore a
|
||||
<a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Link.html"><code>Link</code></a> will never trigger an external navigation failure.</p>
|
||||
</blockquote>
|
||||
<p>Strictly speaking, a <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Link.html"><code>Link</code></a> is not necessary for navigating to external
|
||||
targets, since by definition the router cannot handle them internally. However,
|
||||
the <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Link.html"><code>Link</code></a> component is more convenient to use, as it automatically sets the
|
||||
<code>rel</code> attribute for the link, when the target is external.</p>

<h1 id="links--navigation"><a class="header" href="#links--navigation">Links & Navigation</a></h1>
|
||||
<p>When we split our app into pages, we need to provide our users with a way to
|
||||
navigate between them. On regular web pages we'd use an anchor element for that,
|
||||
like this:</p>
|
||||
<pre><code class="language-html"><a href="/other">Link to an other page</a>
|
||||
</code></pre>
|
||||
<p>However, we cannot do that when using the router for two reasons:</p>
|
||||
<ol>
|
||||
<li>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.</li>
|
||||
<li>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.</li>
|
||||
</ol>
|
||||
<p>To solve these problems, the router provides us with a <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Link.html"><code>Link</code></a> component we can
|
||||
use like this:</p>
|
||||
<pre><pre class="playground"><code class="language-rust no_run edition2021">
|
||||
<span class="boring">#![allow(unused)]
|
||||
</span><span class="boring">fn main() {
|
||||
</span><span class="boring">// Hidden lines (like this one) make the documentation tests work.
|
||||
</span><span class="boring">extern crate dioxus;
|
||||
</span><span class="boring">use dioxus::prelude::*;
|
||||
</span><span class="boring">extern crate dioxus_router;
|
||||
</span><span class="boring">use dioxus_router::prelude::*;
|
||||
</span>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"
|
||||
}
|
||||
}
|
||||
}
|
||||
<span class="boring">}
|
||||
</span></code></pre></pre>
|
||||
<p>The <code>target</code> in the example above is similar to the <code>href</code> of a regular anchor
|
||||
element. However, it tells the router more about what kind of navigation it
|
||||
should perform:</p>
|
||||
<ul>
|
||||
<li>The example uses <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/navigation/enum.NavigationTarget.html#variant.Internal"><code>Internal</code></a>. We give it an arbitrary path that will be
|
||||
merged with the current URL.</li>
|
||||
<li><a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/navigation/enum.NavigationTarget.html#variant.Named"><code>Named</code></a> allows us to navigate within our app using predefined names.
|
||||
See the chapter about <a href="./name.html">named navigation</a> for more details.</li>
|
||||
<li><a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/navigation/enum.NavigationTarget.html#variant.External"><code>External</code></a> allows us to navigate to URLs outside of our app. See the
|
||||
chapter about <a href="./external.html">external navigation</a> for more details.</li>
|
||||
</ul>
|
||||
<blockquote>
|
||||
<p>The <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Link.html"><code>Link</code></a> accepts several props that modify its behavior. See the API docs
|
||||
for more details.</p>

|
||||
<p>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.</p>
|
||||
<p>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.</p>
|
||||
<p><em>Named</em> navigation has a few advantages over <em>path-based</em> navigation:</p>
|
||||
<ul>
|
||||
<li>Links can be created without knowing the actual path.</li>
|
||||
<li>It is much easier to find all links to a specific route.</li>
|
||||
<li>The router knows what links are invalid (and will panic in debug builds).</li>
|
||||
</ul>
|
||||
<blockquote>
|
||||
<p>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
|
||||
<a href="../failures/named.html">named navigation failures</a>.</p>
|
||||
</blockquote>
|
||||
<blockquote>
|
||||
<p>The router will automatically define the name <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/prelude/struct.RootIndex.html"><code>RootIndex</code></a> to refer to the
|
||||
root index route (<code>/</code>).</p>
|
||||
<p>It will also add other names (all of them are in the prelude module) in
|
||||
certain conditions. None of these names can be used for app defined routes.</p>

<p>We can use the <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/hooks/struct.Navigator.html"><code>Navigator</code></a> to trigger four different kinds of navigation:</p>
|

<ul>
|

<li><code>push</code> will navigate to the target. It works like a regular anchor tag.</li>
|
||||
<li><code>replace</code> works like <code>push</code>, 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.</li>
|
||||
<li><code>Go back</code> works like the browsers back button.</li>
|

<li><code>Go forward</code> works like the browsers forward button (the opposite of the back

button).</li>

<p>You might have noticed that, like <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Link.html"><code>Link</code></a>, the <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/hooks/struct.Navigator.html"><code>Navigator</code></a>s <code>push</code> and
|
||||
<code>replace</code> functions take a <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/navigation/enum.NavigationTarget.html"><code>NavigationTarget</code></a>. This means we can use
|

<a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/navigation/enum.NavigationTarget.html#variant.Internal"><code>Internal</code></a>, <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/navigation/enum.NavigationTarget.html#variant.Named"><code>Named</code></a> and <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/navigation/enum.NavigationTarget.html#variant.External"><code>External</code></a>.</p>

<p>Unlike a <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Link.html"><code>Link</code></a>, the <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/hooks/struct.Navigator.html"><code>Navigator</code></a> cannot rely on the browser (or webview) to

handle navigation to external targets via a generated anchor element.</p>

<p>This means, that under certain conditions, navigation to external targets can

fail. See the chapter about

simultaneously. For example, we might have a sidebar that changes its content in
|

sync with the main part of the page.</p>
|

<p>When defining our routes, we can use <code>RouteContentMulti</code> instead of
|

<code>RouteContent::Component</code> (we've been using this through the <code>Into</code> trait) to
|

tell the router about our content.</p>
|
||||
<p>We then can use a named <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Outlet.html"><code>Outlet</code></a> in our output, to tell the router where to
|

put the side content.</p>

<p>The <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Outlet.html"><code>Outlet</code></a> in the <code>App</code> component has no parent <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Outlet.html"><code>Outlet</code></a>, so its depth
|
||||
will be <code>0</code>. When rendering for the path <code>/</code>, it therefore will render the
|
||||
<code>Content</code> component.</p>
|
||||
<p>The <code>Content</code> component will render an <code>h1</code> and an <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Outlet.html"><code>Outlet</code></a>. That <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Outlet.html"><code>OUtlet</code></a>
|

would usually have a depth of <code>1</code>, since it is a descendant of the <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Outlet.html"><code>Outlet</code></a> in

the <code>App</code> component. However, we override its depth to <code>0</code>, so it will render

the <code>Content</code> component.</p>
|

<p>That means the <code>Content</code> component will recurse until someone (e.g. the OS) puts

a stop to it.</p>

<p>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.</p>
|

<blockquote>
|

<p>If you want to change what route is active based on the format of the
|
||||
parameter, see <a href="./matching.html">Matching Routes</a>.</p>
|
||||
</blockquote>
|
||||
<blockquote>
|
||||
<p>The parameter will be URL decoded.</p>

</blockquote>
|
||||
<h2 id="creating-a-content-component"><a class="header" href="#creating-a-content-component">Creating a content component</a></h2>
|
||||
<p>We start by creating a component that uses the parameters value.</p>
|
||||
<p>We can get the current state of the router using the <a href="https://docs.rs/dioxus-router/latest/dioxus_router/hooks/fn.use_route.html"><code>use_route</code></a> 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.</p>
|
||||
<blockquote>
|
||||
<p>It is <strong>VERY IMPORTANT</strong> to drop the object returned by the <a href="https://docs.rs/dioxus-router/latest/dioxus_router/hooks/fn.use_route.html"><code>use_route</code></a>
|
||||
hook once our component finished rendering. Otherwise the entire router will
|
||||
be frozen.</p>
|
||||
</blockquote>
|
||||
<blockquote>
|
||||
<p>The <a href="https://docs.rs/dioxus-router/latest/dioxus_router/hooks/fn.use_route.html"><code>use_route</code></a> hook can only be used in components nested within a
|
||||
component that called <a href="https://docs.rs/dioxus-router/latest/dioxus_router/hooks/fn.use_router.html"><code>use_router</code></a>.</p>

<li>If the segment is not specified (i.e. <code>/</code>), then the index route will be

<li>If a <a href="./matching.html"><em>matching</em> route</a> matches the current path, it will be

<p>Step 0 means that if we want a parameter to be empty, that needs to be specified

by the path, i.e. <code>//</code>.</p>

<blockquote>
|
||||
<p>Be careful with using catch all routes on the root <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/routes/struct.Segment.html"><code>Segment</code></a>. Navigating to
|
||||
paths starting with <code>//</code> will <strong>NOT</strong> work. This is not a limitation of the
|
||||
router, but rather of how relative URLs work.</p>
|
||||
<p>If you absolutely need an empty parameter on the root <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/routes/struct.Segment.html"><code>Segment</code></a>, a URL like
|
||||
this <em>could</em> work:</p>
|
||||
<ul>
|
||||
<li><code>https://your-site.example//</code> for web sites</li>
|
||||
<li><code>dioxus://index.html//</code> for desktop apps</li>

|
||||
<p>In some cases we might want to show different fallback content depending on what
|
||||
section of our app the user is in.</p>
|
||||
<p>For example, our app might have several settings pages under <code>/settings</code>, such
|
||||
as the password settings <code>/settings/password</code> or the privacy settings
|
||||
<code>/settings/privacy</code>. When our user is in the settings section, we want to show
|
||||
them <em>"settings not found"</em> instead of <em>"page not found"</em>.</p>
|
||||
<p>We can easily do that by setting a fallback route on our nested <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/routes/struct.Segment.html"><code>Segment</code></a>. It
|
||||
will then replace the global fallback whenever our <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/routes/struct.Segment.html"><code>Segment</code></a> was active.</p>
|
||||
<p>Note the <code>.clear_fallback(false)</code> part. If we didn't add this, the fallback
|
||||
content would be rendered inside the <code>Settings</code> component.</p>

|

<p>When creating a router we need to pass it a <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/routes/struct.Segment.html"><code>Segment</code></a>. It tells the router
|
||||
about all the routes of our app.</p>
|
||||
<h2 id="example-content"><a class="header" href="#example-content">Example content</a></h2>
|
||||
<p>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.</p>

<p>Index routes act very similar to <code>index.html</code> files in most web servers. They

are active, when we don't specify a route.</p>

<blockquote>

|

<p>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 <a href="../outlets.html#named-outlets">named <code>Outlet</code>s</a>.</p>
|
||||
<h2 id="redirects"><a class="header" href="#redirects">Redirects</a></h2>
|
||||
<p>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.</p>
|
||||
<blockquote>
|
||||
<p>Redirects to external pages only work in certain conditions. For more details
|
||||
see the chapter about <a href="../failures/external.html">external navigation failures</a>.</p>
|
||||
</blockquote>
|
||||
<p>In the following example we will redirect everybody from <code>/</code> and <code>/start</code> to
|
||||
<code>/home</code>.</p>

<h1 id="nested-routes"><a class="header" href="#nested-routes">Nested Routes</a></h1>
|
||||
<p>When developing bigger applications we often want to nest routes within each
|
||||
other. As an example, we might want to organize a settings menu using this
|
||||
pattern:</p>
|
||||
<pre><code class="language-plain">└ Settings
|
||||
├ General Settings (displayed when opening the settings)
|
||||
├ Change Password
|
||||
└ Privacy Settings
|
||||
</code></pre>
|
||||
<p>We might want to map this structure to these paths and components:</p>
|
||||
<pre><code class="language-plain">/settings -> Settings { GeneralSettings }
|
||||
/settings/password -> Settings { PWSettings }
|
||||
/settings/privacy -> Settings { PrivacySettings }
|
||||
</code></pre>
|
||||
<p>Nested routes allow us to do this.</p>
|
||||
<h2 id="route-depth"><a class="header" href="#route-depth">Route Depth</a></h2>
|
||||
<p>With nesting routes, the router manages content on multiple levels. In our
|
||||
example, when the path is <code>/settings</code>, there are two levels of content:</p>
|
||||
<ol start="0">
|
||||
<li>The <code>Settings</code> component</li>
|
||||
<li>The <code>GeneralSettings</code> component</li>
|
||||
</ol>
|
||||
<p>Dioxus Router uses the <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Outlet.html"><code>Outlet</code></a> component to actually render content, but each
|
||||
<a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Outlet.html"><code>Outlet</code></a> can only render content from one level. This means that for the
|
||||
content of nested routes to actually be rendered, we also need nested
|
||||
<a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Outlet.html"><code>Outlet</code></a>s.</p>
|
||||
<h2 id="defining-the-content-components"><a class="header" href="#defining-the-content-components">Defining the content components</a></h2>
|
||||
<p>We start by creating the components we want the router to render.</p>
|
||||
<p>Take a look at the <code>Settings</code> component. When it gets rendered by an <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Outlet.html"><code>Outlet</code></a>,
|
||||
it will render a second <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Outlet.html"><code>Outlet</code></a>. Thus the second <a href="https://docs.rs/dioxus-router/latest/dioxus_router/components/fn.Outlet.html"><code>Outlet</code></a> is nested within
|
||||
the first one, and will in turn render our nested content.</p>

<h1 id="routing-update-callback"><a class="header" href="#routing-update-callback">Routing Update Callback</a></h1>
|
||||
<p>In some cases we might want to run custom code when the current route changes.
|
||||
For this reason, the <a href="https://docs.rs/dioxus-router/latest/dioxus_router/hooks/struct.RouterConfiguration.html"><code>RouterConfiguration</code></a> exposes an <code>on_update</code> field.</p>
|
||||
<h2 id="how-does-the-callback-behave"><a class="header" href="#how-does-the-callback-behave">How does the callback behave?</a></h2>
|
||||
<p>The <code>on_update</code> is called whenever the current routing information changes. It
|
||||
is called after the router updated its internal state, but before depended
|
||||
components and hooks are updated.</p>
|
||||
<p>If the callback returns a <a href="https://docs.rs/dioxus-router-core/latest/dioxus_router_core/navigation/enum.NavigationTarget.html"><code>NavigationTarget</code></a>, the router will replace the
|
||||
current location with the specified target. It will not call the
|
||||
<code>on_update</code> again.</p>
|
||||
<p>If at any point the router encounters a
|
||||
<a href="./failures/index.html">navigation failure</a>, it will go to the appropriate state
|
||||
without calling the <code>on_update</code>. It doesn't matter if the invalid target
|
||||
initiated the navigation, was found as a redirect target or returned by the
|
||||
<code>on_update</code> itself.</p>
