Development Patterns

Component Architecture

• Use functional components with hooks (use_signal, use_effect)
• Implement proper prop typing with Rust structs
• Leverage children for composition
• Use cx.render for conditional rendering
• New: fn Component(cx: Scope) -> Element syntax

State Management (0.7 Updates)

• Local state: use_signal hook (preferred over use_state)
• Global state: Copy/Clone signals or context providers
• Server state: Use server functions with new #[server] macro
• Signals are now Copy and Clone by default

Routing (0.7 Rewrite)

use dioxus_router::prelude::*;

#[derive(Clone, Routable, Debug, PartialEq)]
enum Route {
    #[route("/")]
    Home {},
    #[route("/blog/:id")]
    BlogPost { id: u32 },
    #[route("/about")]
    About {},
    #[nest("/admin")]
        #[route("/dashboard")]
        AdminDashboard {},
    #[end_nest]
    #[route("/:..route")]
    NotFound { route: Vec<String> },
}

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

Data Fetching (0.7 Server Functions)

use dioxus::prelude::*;

#[server]
async fn get_user(id: u32) -> Result<User, ServerFnError> {
    // Database logic here
    let user = sqlx::query_as::<_, User>("SELECT * FROM users WHERE id = $1")
        .bind(id)
        .fetch_one(&db)
        .await?;
    Ok(user)
}

// Client usage
fn UserComponent(cx: Scope, id: u32) -> Element {
    let user = use_resource(cx, || async move { get_user(id).await });

    render! {
        div {
            match &*user.read() {
                Some(Ok(user)) => rsx! { "Hello, {user.name}" },
                Some(Err(e)) => rsx! { "Error: {e}" },
                None => rsx! { "Loading..." },
            }
        }
    }
}

Styling (0.7 Enhancements)

• CSS-in-Rust with dioxus-css or dioxus-free-components
• Tailwind CSS integration with dioxus-tailwind
• Scoped CSS with CSS modules support
• New CSS hot-reloading in development
• Inline styles for dynamic styling

Best Practices

• Use use_callback for stable event handlers

Error Handling

• Use Result types throughout
• Implement proper error boundaries with ErrorBoundary
• Server function error propagation
• Graceful fallbacks for network failures

Testing

• Component unit tests with dioxus-testing
• Integration tests for fullstack
• E2E testing with Playwright or similar
• Server function testing
• New: Headless rendering for tests

Security

• Input validation and sanitization
• CSRF protection for server functions
• Proper authentication/authorization
• Environment variable management
• New: Built-in XSS protection

Common Patterns

Form Handling (0.7 Signals)

#[component]
fn LoginForm(cx: Scope) -> Element {
    let mut email = use_signal(cx, || "".to_string());
    let mut password = use_signal(cx, || "".to_string());
    let mut errors = use_signal(cx, Vec::<String>::new);

    let |_| {
        // Validation and submission logic
        if email.read().is_empty() {
            errors.write().push("Email is required".to_string());
        }
    };

    render! {
        form { onsubmit: on_submit,
            input {
                type: "email",
                value: "{email}",
                oninput: move |e| email.set(e.value())
            }
            input {
                type: "password",
                value: "{password}",
                oninput: move |e| password.set(e.value())
            }
            for error in errors.read() {
                div { class: "error", "{error}" }
            }
            button { type: "submit", "Login" }
        }
    }
}

API Integration (0.7 Server Functions)

#[server]
async fn create_post(title: String, content: String) -> Result<Post, ServerFnError> {
    // Validate input
    if title.is_empty() {
        return Err(ServerFnError::ServerError("Title cannot be empty".to_string()));
    }

    // Database insertion
    let post = sqlx::query_as::<_, Post>(
        "INSERT INTO posts (title, content) VALUES ($1, $2) RETURNING *"
    )
    .bind(&title)
    .bind(&content)
    .fetch_one(&db)
    .await?;

    Ok(post)
}

// Usage in component
#[component]
fn PostForm(cx: Scope) -> Element {
    let mut title = use_signal(cx, || "".to_string());
    let mut content = use_signal(cx, || "".to_string());

    let create_post = use_server_future(cx, (title(), content()), |(title, content)| async move {
        create_post(title, content).await
    });

    render! {
        form {
            input {
                value: "{title}",
                oninput: move |e| title.set(e.value())
            }
            textarea {
                value: "{content}",
                oninput: move |e| content.set(e.value())
            }
            button { onclick: move |_| create_post.restart(), "Create Post" }

            match create_post.read() {
                Some(Ok(post)) => rsx! { div { "Created: {post.title}" } },
                Some(Err(e)) => rsx! { div { "Error: {e}" } },
                None => rsx! { div { "Creating..." } },
            }
        }
    }
}

Custom Hooks (0.7 Patterns)

#[hook]
pub fn use_api<T: Clone + 'static>(
    cx: Scope,
    endpoint: String
) -> UseResource<Result<T, reqwest::Error>> {
    use_resource(cx, || async move {
        reqwest::get(&endpoint).await?.json::<T>().await
    })
}

#[hook]
pub fn use_debounce(cx: Scope, value: String, delay_ms: u64) -> Signal<String> {
    let debounced = use_signal(cx, || value.clone());

    use_effect(cx, (value,), |(value,)| {
        spawn(async move {
            tokio::time::sleep(Duration::from_millis(delay_ms)).await;
            debounced.set(value.clone());
        });
        || ()
    });

    debounced
}

Architecture Tips

1. Separate Concerns: Keep server and client logic distinct with clear boundaries
2. Type Safety: Leverage Rust's type system across the full stack
3. Error Boundaries: Implement graceful error handling at component level
4. Code Splitting: Use lazy loading and suspense boundaries for optimal bundle sizes
5. Environment Management: Proper dev/staging/prod configuration
6. Signal Best Practices: Use signals for derived state and computed values
7. Server Function Design: Keep server functions focused and testable
8. Performance Monitoring: Use built-in performance tracking and profiling tools

This skill provides the essential knowledge and patterns for building robust, performant fullstack applications with Dioxus 0.7 while maintaining Rust's safety and ergonomics throughout the entire development lifecycle.
