🔄 Migration Guide

From v0.3.1 to v0.3.2

Trait Imports (Required)

// Add these imports for Leptos 0.8.8 compatibility
use leptos::prelude::{
    ElementChild, 
    ClassAttribute, 
    StyleAttribute, 
    OnAttribute, 
    IntoAny,
    signal,
    Get,
    Update
};

Component Props

// MotionDiv and MotionSpan now support children
<MotionDiv initial={...} animate={...}>
    {children} // Now supported!
</MotionDiv>

AnimationTarget

// Use explicit HashMap instead of motion_target! macro
let mut target = HashMap::new();
target.insert("opacity".to_string(), AnimationValue::Number(0.0));
target.insert("scale".to_string(), AnimationValue::Number(1.0));

🚧 Known Limitations

Partially Working (Use with Caution)

  • MotionDiv/MotionSpan: Components exist but animation logic is stubbed
  • Gesture System: Structure exists but not fully implemented
  • Layout Animations: FLIP animations are partially implemented
  • Advanced Performance: GPU acceleration needs more work

Not Ready Yet

  • Complex Gestures: Drag, swipe, pinch gestures
  • Layout Animations: Shared element transitions
  • Advanced Performance: Full GPU acceleration
  • Production Features: Complete error handling, accessibility

🎯 Recommended Usage

Start Simple

use leptos_motion_core::*;
use leptos::prelude::*;

#[component]
pub fn MyComponent() -> impl IntoView {
    let (animated, set_animated) = signal(false);
    
    view! {
        <div
            style=move || format!(
                "opacity: {}; transform: scale({}); transition: all 0.3s ease;",
                if animated.get() { "1.0" } else { "0.5" },
                if animated.get() { "1.0" } else { "0.8" }
            )
            on:click=move |_| set_animated.update(|a| *a = !*a)
        >
            "Click me!"
        </div>
    }
}

Use MinimalEngine

let engine = MinimalEngine::new();
// Engine is ready for basic animations
