Code
Just the sample code from the leptos start-axum crate. Specifically app.rs:
use crate::error_template::{AppError, ErrorTemplate};
use leptos::*;
use leptos_meta::*;
use leptos_router::*;
#[component]
pub fn App() -> impl IntoView {
// Provides context that manages stylesheets, titles, meta tags, etc.
provide_meta_context();
view! {
// injects a stylesheet into the document <head>
// id=leptos means cargo-leptos will hot-reload this stylesheet
<Stylesheet id="leptos" href="/pkg/crsche-com.css"/>
// sets the document title
<Title text="Welcome to Leptos"/>
// content for this welcome page
<Router fallback=|| {
let mut outside_errors = Errors::default();
outside_errors.insert_with_default_key(AppError::NotFound);
view! {
<ErrorTemplate outside_errors/>
}
.into_view()
}>
<main>
<Routes>
<Route path="" view=HomePage/>
</Routes>
</main>
</Router>
}
}
/// Renders the home page of your application.
#[component]
fn HomePage() -> impl IntoView {
// Creates a reactive value to update the button
let (count, set_count) = create_signal(0);
let on_click = move |_| set_count.update(|count| *count += 1);
view! {
<h1>"Welcome to Leptos!"</h1>
<button on:click=on_click>"Click Me: " {count}</button>
}
}Meta
