|
|
<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>The easiest thing to do is to define an index route.</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>Note that we wrap our <code>Index</code> component with <a href="https://docs.rs/dioxus-router/latest/dioxus_router/prelude/fn.comp.html"><code>comp</code></a>. This is because of
|
|
rust type system requirements.</p>

<h2 id="fixed-routes"><a class="header" href="#fixed-routes">Fixed routes</a></h2>
|
|
<p>It is almost as easy to define a fixed route.</p>
|
|
<p>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 <code>/other</code>.</p>
|
|
<blockquote>
|
|
<p>The path will be URL decoded before checking if it matches our route.</p>
