# Architecture Documentation
This document provides a comprehensive overview of the Rust shadcn/ui architecture, design patterns, and implementation strategies.
## System Overview
Rust shadcn/ui is a modular, multi-framework UI component library that provides shadcn/ui components for Rust web applications. The architecture emphasizes type safety, performance, and framework flexibility while maintaining design consistency.
### Core Principles
1. **Component Isolation**: Each component is a separate crate for maximum modularity
2. **Framework Parity**: Consistent API across all supported frameworks
3. **Theme Support**: Default and New York variants for all components
4. **Type Safety**: Leverage Rust's type system for component properties
5. **Performance**: Minimal runtime overhead and optimal bundle sizes
## Workspace Architecture

```
## Component Architecture
### Design Patterns
#### 1. Component Isolation Pattern
Each component is implemented as a separate Cargo crate:
**Benefits:**
- Independent versioning and dependency management
- Granular imports (users only import what they need)
- Parallel compilation and development
- Clear separation of concerns
**Implementation:**
```rust
// packages/leptos/button/Cargo.toml
[package]
name = "shadcn-ui-leptos-button"
version = "0.1.0"
edition = "2021"
[dependencies]
leptos = "0.6"
tailwind_fuse = "0.3"
```
#### 2. Theme Variant Pattern
Components support multiple design themes through a dual-module approach:
```rust
// src/lib.rs - Public API
pub mod default;
pub mod new_york;
// Re-export default theme at crate root
pub use default::*;
// Named export for alternative theme
pub use new_york as new_york;
```
**Usage:**
```rust
// Default theme (implicit)
use shadcn_ui_leptos_button::Button;
// New York theme (explicit)
use shadcn_ui_leptos_button::new_york::Button;
```
#### 3. Styling Composition Pattern
Dynamic CSS class composition using `tailwind_fuse`:
```rust
#[derive(TwClass)]
#[tw(
class = "inline-flex items-center justify-center rounded-md font-medium",
variants(
variant(
default = "bg-primary text-primary-foreground hover:bg-primary/90",
destructive = "bg-destructive text-destructive-foreground hover:bg-destructive/90",
outline = "border border-input bg-background hover:bg-accent",
),
size(
default = "h-10 px-4 py-2",
sm = "h-9 rounded-md px-3",
lg = "h-11 rounded-md px-8",
)
)
)]
pub struct ButtonClass {
pub variant: ButtonVariant,
pub size: ButtonSize,
}
```
#### 4. Props Pattern
Consistent property handling across frameworks:
**Leptos:**
```rust
#[component]
pub fn Button(
#[prop(optional)] variant: MaybeProp<ButtonVariant>,
#[prop(optional)] size: MaybeProp<ButtonSize>,
#[prop(optional)] disabled: MaybeProp<bool>,
#[prop(optional)] class: MaybeProp<String>,
children: Children,
) -> impl IntoView
```
**Yew:**
```rust
#[derive(Properties, PartialEq)]
pub struct ButtonProps {
#[prop_or_default]
pub variant: ButtonVariant,
#[prop_or_default]
pub size: ButtonSize,
#[prop_or_default]
pub disabled: bool,
#[prop_or_default]
pub class: String,
pub children: Children,
}
```
## Framework Integration
### Leptos Integration
**Key Features:**
- Signal-based reactivity
- Server-side rendering (SSR) support
- Hydration-friendly components
- `view!` macro for declarative UI
**Architecture Patterns:**
**Reactive State Management:**
```rust
#[component]
pub fn Toggle() -> impl IntoView {
let (checked, set_checked) = create_signal(false);
let toggle_class = create_memo(move |_| {
ToggleClass {
pressed: checked.get(),
size: ToggleSize::Default,
}
});
view! {
<button
type="button"
role="switch"
aria-checked=move || checked.get()
class=toggle_class
on:click=move |_| set_checked.update(|c| *c = !*c)
>
// Component implementation
</button>
}
}
```
**SSR Compatibility:**
```rust
// Ensure components work in SSR environments
#[component]
pub fn Component() -> impl IntoView {
// Use create_effect for client-only side effects
create_effect(move |_| {
#[cfg(feature = "hydrate")]
{
// Client-only code
}
});
view! { /* SSR-safe markup */ }
}
```
### Yew Integration
**Key Features:**
- Component-based architecture
- Virtual DOM diffing
- WebAssembly optimization
- Hook-based state management
**Architecture Patterns:**
**Component State:**
```rust
#[function_component]
pub fn Toggle() -> Html {
let checked = use_state(|| false);
let toggle_class = use_memo(
{
let checked = checked.clone();
move |_| ToggleClass {
pressed: *checked,
size: ToggleSize::Default,
}
},
(),
);
let onclick = {
let checked = checked.clone();
Callback::from(move |_| {
checked.set(!*checked);
})
};
html! {
<button
type="button"
role="switch"
aria-checked={checked.to_string()}
class={classes!(&*toggle_class)}
{onclick}
>
// Component implementation
</button>
}
}
```
**Performance Optimization:**
```rust
// Use memo for expensive computations
let complex_calculation = use_memo(
|props| expensive_function(&props.data),
props.clone(),
);
// Use callback for event handlers
let onclick = use_callback(
|(event, props)| handle_click(event, &props.data),
props.clone(),
);
```
## Styling Architecture
### TailwindCSS Integration
**Design System Foundation:**
- Consistent spacing scale (0.25rem increments)
- Type scale with semantic naming
- Color system with semantic tokens
- Component-specific utility classes
**CSS Custom Properties:**
```css
:root {
--background: 0 0% 100%;
--foreground: 222.2 84% 4.9%;
--card: 0 0% 100%;
--card-foreground: 222.2 84% 4.9%;
--popover: 0 0% 100%;
--popover-foreground: 222.2 84% 4.9%;
--primary: 222.2 47.4% 11.2%;
--primary-foreground: 210 40% 98%;
--secondary: 210 40% 96%;
--secondary-foreground: 222.2 47.4% 11.2%;
--muted: 210 40% 96%;
--muted-foreground: 215.4 16.3% 46.9%;
--accent: 210 40% 96%;
--accent-foreground: 222.2 47.4% 11.2%;
--destructive: 0 84.2% 60.2%;
--destructive-foreground: 210 40% 98%;
--border: 214.3 31.8% 91.4%;
--input: 214.3 31.8% 91.4%;
--ring: 222.2 84% 4.9%;
--radius: 0.5rem;
}
```
**Dark Mode Support:**
```css
.dark {
--background: 222.2 84% 4.9%;
--foreground: 210 40% 98%;
/* ... */
}
```
### Component Styling Patterns
**Base Component Classes:**
```rust
#[derive(TwClass)]
#[tw(class = "base-classes")]
pub struct ComponentClass {
// Variant properties
}
```
**Variant System:**
```rust
#[derive(TwClass)]
#[tw(
class = "base-classes",
variants(
// Visual variants
variant(
default = "default-styles",
secondary = "secondary-styles",
destructive = "destructive-styles",
),
// Size variants
size(
sm = "small-styles",
default = "default-styles",
lg = "large-styles",
)
),
// Default variants
defaults(
variant = default,
size = default
)
)]
```
**Responsive Design:**
```rust
// Mobile-first responsive classes
"w-full sm:w-auto md:w-64 lg:w-80"
// Container queries (when supported)
"@container/sidebar:md:w-64"
```
## Code Generation System
### Template Architecture
**Handlebars Template System:**
```handlebars
{{!-- Base template structure --}}
use {{framework}}::*;
use tailwind_fuse::*;
{{#if has_props}}
#[derive({{prop_derives}})]
pub struct {{component_name}}Props {
{{#each props}}
{{#if optional}}#[prop_or_default]{{/if}}
pub {{name}}: {{prop_type}},
{{/each}}
}
{{/if}}
{{framework_component_macro}}
pub fn {{component_name}}(
{{#each props}}
{{#if @first}}{{else}},{{/if}}
{{render_prop_parameter this}}
{{/each}}
) -> {{return_type}} {
{{render_component_body}}
}
```
**Framework-Specific Templates:**
- `leptos_component.hbs` - Leptos component structure
- `yew_component.hbs` - Yew component structure
- `dioxus_component.hbs` - Dioxus component structure (planned)
**Configuration System:**
```rust
pub struct ComponentConfig {
pub name: String,
pub framework: Framework,
pub theme_variants: Vec<String>,
pub props: HashMap<String, PropConfig>,
pub dependencies: Vec<String>,
}
```
## Testing Architecture
### Framework Testing Patterns
**Leptos Testing:**
```rust
#[cfg(test)]
mod tests {
use super::*;
use leptos::*;
use leptos_dom::*;
#[test]
fn test_button_render() {
let _ = create_runtime();
let button = Button(ButtonProps {
variant: ButtonVariant::Default,
children: "Click me".into(),
..Default::default()
});
// Assert component properties
assert!(button.is_ok());
}
}
```
**Yew Testing:**
```rust
#[cfg(test)]
mod tests {
use super::*;
use yew::prelude::*;
use yew::html;
#[test]
fn test_button_render() {
let props = ButtonProps {
variant: ButtonVariant::Default,
children: html! { "Click me" }.into(),
..Default::default()
};
let button = html! { <Button ..props /> };
// Test rendering
assert!(!button.is_empty());
}
}
```
### Integration Testing
**Component Integration:**
```rust
// tests/integration/button_test.rs
use shadcn_ui_leptos_button::Button;
use shadcn_ui_yew_button::Button as YewButton;
#[test]
fn test_component_parity() {
// Test that Leptos and Yew buttons have equivalent APIs
// and render similar output structures
}
```
## Performance Considerations
### Bundle Size Optimization
**Tree Shaking:**
- Each component as separate crate enables fine-grained imports
- Users only bundle components they actually use
- Framework-specific optimizations applied automatically
**Lazy Loading:**
```rust
// Dynamic imports for large components
use leptos_router::*;
#[component]
pub fn App() -> impl IntoView {
view! {
<Router>
<Route
path="/dashboard"
view=|| {
// Lazy load heavy dashboard components
provide_context(DashboardContext::new());
view! { <DashboardPage /> }
}
/>
</Router>
}
}
```
### Runtime Performance
**Memoization Patterns:**
```rust
// Leptos
let expensive_calculation = create_memo(move |_| {
expensive_function(props.data())
});
// Yew
let expensive_calculation = use_memo(
|props| expensive_function(&props.data),
props.clone(),
);
```
**Event Handler Optimization:**
```rust
// Avoid recreating handlers on every render
let onclick = create_callback(move |event| {
// Handler logic
});
```
## Security Considerations
### XSS Prevention
**HTML Sanitization:**
```rust
// Always sanitize user-provided HTML content
use ammonia::clean;
let safe_html = clean(&user_input);
```
**Attribute Validation:**
```rust
// Validate and sanitize component attributes
pub fn sanitize_class_name(class: &str) -> String {
class.chars()
.filter(|c| c.is_alphanumeric() || *c == '-' || *c == '_')
.collect()
}
```
### Dependency Security
**Supply Chain Security:**
- Pin dependency versions in Cargo.lock
- Regular security audits with `cargo audit`
- Minimal dependency footprint
- Prefer well-maintained, popular crates
## Accessibility Architecture
### ARIA Integration
**Component Accessibility:**
```rust
view! {
<button
type="button"
role="switch"
aria-checked=move || checked.get()
aria-describedby=description_id
class=toggle_class
>
<span class="sr-only">
{move || if checked.get() { "On" } else { "Off" }}
</span>
</button>
}
```
**Screen Reader Support:**
- Semantic HTML elements by default
- ARIA labels and descriptions
- Focus management
- Keyboard navigation support
### Keyboard Navigation
**Focus Management:**
```rust
use leptos_use::*;
#[component]
pub fn Dialog(show: ReadSignal<bool>) -> impl IntoView {
let dialog_ref = create_node_ref::<html::Div>();
// Trap focus within dialog when open
let _ = use_focus_trap(dialog_ref, show);
// Return focus to trigger when closed
let _ = use_focus_return(dialog_ref, show);
view! {
<div node_ref=dialog_ref>
// Dialog content
</div>
}
}
```
## Documentation Architecture
### API Documentation
**Rust Doc Standards:**
```rust
/// A button component that triggers an action or event.
///
/// The button component supports multiple variants and sizes, and can be
/// customized with additional CSS classes.
///
/// # Examples
///
/// ```rust
/// use shadcn_ui_leptos_button::*;
///
/// let button = view! {
/// <Button variant=ButtonVariant::Primary>
/// "Click me"
/// </Button>
/// };
/// ```
///
/// # Accessibility
///
/// The button component includes proper ARIA attributes and keyboard
/// navigation support by default.
#[component]
pub fn Button(/* ... */) -> impl IntoView {
// Implementation
}
```
**Component Examples:**
```rust
/// # Component Variants
///
/// ```rust
/// // Primary button
/// view! { <Button variant=ButtonVariant::Primary>"Primary"</Button> }
///
/// // Secondary button
/// view! { <Button variant=ButtonVariant::Secondary>"Secondary"</Button> }
///
/// // Disabled button
/// view! { <Button disabled=true>"Disabled"</Button> }
/// ```

# Component Generator Documentation
The Rust shadcn/ui component generator is a powerful tool for creating consistent, framework-specific UI components with full theme variant support.
## Overview
The component generator creates scaffolded components that follow established patterns and conventions across different Rust web frameworks. It handles the boilerplate code, file structure, and framework-specific implementations automatically.
## Architecture
### Core Components
```
packages/component-generator/
├── src/
│ ├── lib.rs # Core types and generator
│ ├── generator.rs # Generation logic
│ └── templates/ # Handlebars templates
│ ├── leptos_component.hbs
│ ├── yew_component.hbs
│ └── lib_rs.hbs
```
### Framework Support
| Framework | Status | Template | Features |
|-----------|---------|----------|----------|
| **Leptos** | ✅ Stable | `leptos_component.hbs` | Signal-based reactivity, SSR |
| **Yew** | ✅ Stable | `yew_component.hbs` | Component architecture, Virtual DOM |
| **Dioxus** | 🚧 Planned | `dioxus_component.hbs` | Cross-platform support |
## Configuration System
### ComponentConfig
```rust
pub struct ComponentConfig {
pub name: String, // Component name (kebab-case)
pub framework: Framework, // Target framework
pub theme_variants: Vec<String>, // ["default", "new_york"]
pub props: HashMap<String, PropConfig>, // Component properties
pub dependencies: Vec<String>, // External dependencies
}
```
### PropConfig
```rust
pub struct PropConfig {
pub prop_type: String, // Rust type (String, bool, Option<T>)
pub optional: bool, // Whether prop is optional
pub default_value: Option<String>, // Default value expression
pub description: Option<String>, // Documentation
}
```
## Template System
### Handlebars Templates
The generator uses Handlebars templating engine for flexible, maintainable code generation:
```handlebars
{{!-- leptos_component.hbs example --}}
use leptos::*;
use tailwind_fuse::*;
#[component]
pub fn {{name}}(
{{#each props}}
{{@key}}: {{prop_type}},
{{/each}}
) -> impl IntoView {
view! {
<div class=move || {{name}}Class::default()>
// Component implementation
</div>
}
}
```
### Theme Variants
Each component generates both theme variants:
- **Default Theme**: Clean, minimal design
- **New York Theme**: Sophisticated, enterprise styling
Templates automatically handle theme-specific styling through CSS class generation.
## CLI Integration
### Command Structure
```bash
cargo run -p shadcn -- generate [OPTIONS] --name <NAME>
```
### Available Options
| Flag | Type | Description | Default |
|------|------|-------------|---------|
| `-n, --name` | String | Component name (required) | - |
| `-f, --framework` | String | Target framework | `leptos` |
| `-c, --classes` | String | Base CSS classes | Auto-generated |
| `-t, --tag` | String | Root HTML tag | `div` |
| `-d, --description` | String | Component description | - |
| `--themes` | Bool | Generate both themes | `true` |
### Usage Examples
**Basic Component Generation:**
```bash
cargo run -p shadcn -- generate --name "tooltip" --framework "leptos"
```
**Component with Custom Styling:**
```bash
cargo run -p shadcn -- generate \
--name "dialog" \
--framework "yew" \
--classes "rounded-md bg-background p-6 shadow-lg" \
--description "A modal dialog component"
```
**Multi-Framework Generation:**
```bash
# Generate for Leptos
cargo run -p shadcn -- generate --name "slider" --framework "leptos"
# Generate for Yew
cargo run -p shadcn -- generate --name "slider" --framework "yew"
```
## File Generation Patterns
### Directory Structure
```
packages/{framework}/{component-name}/
├── Cargo.toml # Package configuration
├── src/
│ ├── lib.rs # Public exports
│ ├── default.rs # Default theme variant
│ └── new_york.rs # New York theme variant
└── README.md # Component documentation
```
### Generated Files
**Package Configuration (Cargo.toml):**
```toml
[package]
name = "shadcn-ui-{framework}-{component}"
version = "0.1.0"
edition = "2021"
[dependencies]
tailwind_fuse = "0.3"
{framework-specific-deps}
```
**Library Entry Point (lib.rs):**
```rust
//! {Component} component for {Framework}
mod default;
mod new_york;
pub use default::*;
pub use new_york as new_york;
```
**Theme Variants:**
- `default.rs` - Clean, minimal styling
- `new_york.rs` - Sophisticated, enterprise styling
## Framework-Specific Features
### Leptos Components
**Key Features:**
- Signal-based reactivity with `create_signal()`
- Server-side rendering compatibility
- `view!` macro for declarative UI
- MaybeProp for optional properties
**Example Generated Structure:**
```rust
#[component]
pub fn Button(
#[prop(optional)] variant: MaybeProp<ButtonVariant>,
#[prop(optional)] size: MaybeProp<ButtonSize>,
children: Children,
) -> impl IntoView {
let classes = create_memo(move |_| {
ButtonClass {
variant: variant.get(),
size: size.get(),
}
});
view! {
<button class=classes>
{children()}
</button>
}
}
```
### Yew Components
**Key Features:**
- Properties with `#[derive(Properties, PartialEq)]`
- Component trait implementation
- Html return type for render
- Callback handling with `Callback<T>`
**Example Generated Structure:**
```rust
#[derive(Properties, PartialEq)]
pub struct ButtonProps {
#[prop_or_default]
pub variant: ButtonVariant,
#[prop_or_default]
pub size: ButtonSize,
pub children: Children,
}
#[function_component]
pub fn Button(props: &ButtonProps) -> Html {
let classes = use_memo(
|props| ButtonClass {
variant: props.variant,
size: props.size,
},
props.clone(),
);
html! {
<button class={classes}>
{props.children.clone()}
</button>
}
}
```
## Styling System
### TailwindCSS Integration
All generated components use `tailwind_fuse` for dynamic class composition:
```rust
#[derive(TwClass)]
#[tw(
class = "inline-flex items-center justify-center rounded-md text-sm font-medium",
variants(
variant(
primary = "bg-primary text-primary-foreground hover:bg-primary/90",
secondary = "bg-secondary text-secondary-foreground hover:bg-secondary/80",
),
size(
default = "h-10 px-4 py-2",
sm = "h-9 rounded-md px-3",
lg = "h-11 rounded-md px-8",
)
)
)]
pub struct ButtonClass {
pub variant: ButtonVariant,
pub size: ButtonSize,
}
```
### Theme System
**Design Tokens:**
- CSS custom properties for theming
- Consistent color palette across variants
- Responsive design utilities
- Accessibility-first approach
**Color Palette:**
```css
:root {
--background: 0 0% 100%;
--foreground: 222.2 84% 4.9%;
--primary: 222.2 47.4% 11.2%;
--primary-foreground: 210 40% 98%;
--secondary: 210 40% 96%;
--secondary-foreground: 222.2 47.4% 11.2%;
/* ... */
}
```
## Extension Points
### Custom Templates
Add custom templates by registering them in the generator:
```rust
impl ComponentGenerator {
pub fn new() -> Result<Self> {
let mut handlebars = handlebars::Handlebars::new();
// Register custom template
handlebars.register_template_string(
"custom_component",
include_str!("templates/custom_component.hbs")
)?;
Ok(Self { template_engine: handlebars })
}
}
```
### Framework Integration
Adding support for new frameworks:
1. **Add Framework Enum Value:**
```rust
#[derive(Debug, Clone, Copy, Serialize, Deserialize)]
pub enum Framework {
Leptos,
Yew,
Dioxus,
NewFramework, // Add here
}
```
2. **Create Template:**
```handlebars
{{!-- templates/newframework_component.hbs --}}
// Framework-specific component structure
```
3. **Register Template:**
```rust
handlebars.register_template_string(
"newframework_component",
include_str!("templates/newframework_component.hbs")
)?;
```
4. **Update Generation Logic:**
```rust
pub fn generate_component(&self, config: &ComponentConfig) -> Result<String> {
let template_name = match config.framework {
Framework::Leptos => "leptos_component",
Framework::Yew => "yew_component",
Framework::Dioxus => "dioxus_component",
Framework::NewFramework => "newframework_component", // Add here
};
self.template_engine.render(template_name, config)
.map_err(Into::into)
}
```
## Best Practices
### Component Design
1. **Consistent API:** Follow established prop patterns across frameworks
2. **Accessibility:** Include ARIA attributes and semantic HTML
3. **Performance:** Use memoization for expensive computations

1. **Version Pinning:** Use compatible dependency versions
2. **Feature Flags:** Support optional framework features
3. **API Consistency:** Maintain similar APIs across frameworks
4. **Migration Support:** Provide upgrade paths for breaking changes
## Troubleshooting
### Common Issues
**Template Compilation Errors:**
- Verify Handlebars syntax
- Check variable names match config
- Ensure proper escaping for Rust keywords
**Framework Compatibility:**
- Update dependency versions
- Check trait implementations
- Verify macro usage patterns
**Styling Problems:**
- Validate TailwindCSS classes
- Check theme variable references
- Ensure responsive design patterns
### Debug Mode
Enable debug output for template generation:
```bash
RUST_LOG=debug cargo run -p shadcn -- generate --name "test" --framework "leptos"
```
## Contributing
### Adding New Components
1. Study existing component patterns
2. Create templates following conventions
3. Test across all supported frameworks

# Feature Parity Design: Rust shadcn/ui
## Current State Analysis
### ✅ **Existing Architecture**
- **Project Structure**: Monorepo with framework-specific packages (Leptos, Yew)
- **Registry System**: Central registry for component metadata and CLI integration
- **Theme Support**: Default & New York style variants for each component
- **CLI Tool**: `rust-shadcn` for component installation and management
### 📊 **Current Component Coverage**
**Leptos Framework** (44 components - 86% complete):
- accordion, alert, alert-dialog, aspect-ratio, badge, breadcrumb, button, calendar, card, carousel, checkbox, collapsible, combobox, command, context-menu, date-picker, dialog, drawer, dropdown-menu, form, hover-card, input, input-otp, label, menubar, navigation-menu, pagination, popover, progress, radio-group, scroll-area, select, separator, sheet, skeleton, slider, switch, table, tabs, textarea, toast, toggle, tooltip, utils
**Yew Framework** (20 components - 39% complete):
- alert, aspect-ratio, avatar, badge, breadcrumb, button, card, checkbox, dialog, input, label, pagination, radio-group, select, separator, skeleton, switch, table, textarea, tooltip
**Missing from both frameworks** (7 components):
- avatar (Leptos only), data-table, chart, resizable, sidebar, sonner, typography
**Missing from Yew** (25 components):
- accordion, alert-dialog, calendar, carousel, collapsible, combobox, command, context-menu, date-picker, drawer, dropdown-menu, form, hover-card, input-otp, menubar, navigation-menu, popover, progress, scroll-area, sheet, slider, tabs, toast, toggle, utils
## 🎯 **Feature Parity Architecture Design**
### **Phase 1: Foundation Enhancement**
#### **Registry System Optimization**
```rust
// Enhanced registry structure
pub struct ComponentRegistry {
leptos: FrameworkRegistry,
yew: FrameworkRegistry,
dioxus: FrameworkRegistry, // Future framework
}
pub struct FrameworkRegistry {
components: HashMap<String, ComponentDef>,
dependencies: DependencyGraph,
theme_variants: ThemeRegistry,
}
```
#### **Component Generation Pipeline**
```
Source Definition → Framework Adapter → Theme Variants → Output Files
```
### **Phase 2: Systematic Component Implementation**
#### **Priority Matrix**
```yaml
tier_1_critical: [dialog, dropdown-menu, select, checkbox, radio-group]
tier_2_forms: [form, combobox, date-picker, textarea, input-otp]
tier_3_navigation: [navigation-menu, menubar, tabs, breadcrumb]
tier_4_feedback: [toast, alert-dialog, progress, skeleton]
tier_5_layout: [sheet, resizable, scroll-area, collapsible]
tier_6_advanced: [data-table, chart, carousel, command]
```
#### **Framework Parity Strategy**
```
Yew (15) → Leptos (5) = 10 component gap
Target: Leptos reaches Yew parity + Both frameworks implement remaining 36 components
```
### **Phase 3: Advanced Features**
#### **Cross-Framework Compatibility Layer**
```rust
pub trait ShadcnComponent {
type Props;
fn render(props: Self::Props) -> RenderedComponent;
fn theme_variants() -> Vec<ThemeVariant>;
fn dependencies() -> Vec<Dependency>;
}
```
#### **Enhanced CLI Integration**
```bash
# Enhanced command structure
rust-shadcn add <component> --framework <leptos|yew|dioxus>
rust-shadcn init --framework <framework> --theme <default|new-york>
rust-shadcn diff --component <name> --between <version1> <version2>
rust-shadcn sync --target-framework <framework>
```

}
// Leptos implementation pattern
#[component]
pub fn Button(props: ButtonProps) -> impl IntoView {
let classes = create_button_classes(props);
view! { <button class=classes>{props.children}</button> }
}
```
#### 3. Registry Integration
```rust
// Add component to registry_ui.rs
RegistryEntry {
name: "checkbox".into(),
r#type: RegistryItemType::Ui,
description: Some("Checkbox input control".into()),
dependencies: Some(vec!["web-sys".into()]),
files: Some(vec![
RegistryItemFile {

# Leptos 0.8.8 Migration Guide
## 🚨 **CRITICAL ISSUE IDENTIFIED**
The project is currently experiencing compilation failures with Leptos 0.8.8 due to **version inconsistencies** in the dependency tree, not due to fundamental issues with Leptos 0.8.8 itself.
## 🔍 **Root Cause Analysis**
### **Version Mismatch in Cargo.lock**
The `Cargo.lock` file contains mixed Leptos versions:
- **Main packages**: `leptos 0.8.8` ✅
- **Some dependencies**: `leptos_config 0.7.8` ❌ (incompatible)
- **Other dependencies**: `leptos_dom 0.8.6` ❌ (version mismatch)
### **Compilation Error Details**
```
error[E0308]: mismatched types
--> /Users/peterhanssens/.cargo/registry/src/index.crates.io-1949cf8c6b5b557f/leptos-0.8.8/src/hydration/mod.rs:138:5
|
138 | / view! {
139 | <link rel="modulepreload" href=format!("{root}/{pkg_path}/{js_file_name}.js") crossorigin...
140 | <link
141 | rel="preload"
... |
149 | </script>
150 | }
|_____^ expected a tuple with 3 elements, found one with 5 elements
```
**This error occurs because:**
1. Some packages are compiled against Leptos 0.7.x APIs
2. Other packages are compiled against Leptos 0.8.x APIs
3. The type system cannot reconcile these different API expectations
## 🚀 **IMPLEMENTATION PLAN**
### **Phase 1: Fix Version Inconsistencies (CRITICAL)**
#### **Step 1.1: Update Workspace Dependencies**
```toml
[workspace.dependencies]
# BEFORE (causing issues)
leptos = "0.8.6"
leptos_router = "0.8.6"
# AFTER (fixed)
leptos = "0.8.8"
leptos_router = "0.8.8"
```
#### **Step 1.2: Clean Dependency Resolution**
```bash
# Remove existing lock file to force fresh resolution
rm Cargo.lock
# Clean build artifacts
cargo clean
# Rebuild with fresh dependencies
cargo check --workspace
```
### **Phase 2: Fix Component Package Dependencies**
#### **Step 2.1: Update All Component Cargo.toml Files**
Ensure all `packages/leptos/*/Cargo.toml` use workspace versions:
```toml
# BEFORE (hardcoded versions)
leptos = "0.8"
leptos = "0.8.6"
# AFTER (workspace inheritance)
leptos.workspace = true
leptos_router.workspace = true
```
#### **Step 2.2: Fix Specific Component Issues**
##### **Error Boundary Component**
**Problem**: Closure implements `FnOnce` instead of `FnMut`
**Solution**: Clone `children` before moving into closure
```rust
// BEFORE (causes FnOnce error)
move || {
if has_error.get() {
// ... error handling
} else {
children().into_any() // ❌ moves children
}
}
// AFTER (fixes FnMut requirement)
{
let children = children.clone();
move || {
if has_error.get() {
// ... error handling
} else {
children().into_any() // ✅ uses cloned reference
}
}
}
```
##### **Lazy Loading Component**
**Problem**: Type mismatches between `View<()>` and `impl IntoView`
**Solution**: Consistent return type handling
```rust
// BEFORE (type mismatch)
pub fn LazyComponent() -> View<()> {
view! { <div>...</div> }
}
// AFTER (consistent types)
pub fn LazyComponent() -> impl IntoView {
view! { <div>...</div> }
}
```
### **Phase 3: Update Example Application**
#### **Step 3.1: Fix Example Dependencies**
Update `examples/leptos/Cargo.toml`:
```toml
[dependencies]
# Use workspace versions
leptos.workspace = true
leptos_router.workspace = true
# Ensure all component dependencies use workspace versions
shadcn-ui-leptos-button = { path = "../../packages/leptos/button", optional = true }
# ... other components
```
#### **Step 3.2: Fix Import Issues**
```rust
// BEFORE (incorrect imports)
use leptos_shadcn_ui::button::Button;
// AFTER (correct imports)
use shadcn_ui_leptos_button::Button;
```
### **Phase 4: Test and Validate**
#### **Step 4.1: Compilation Verification**
```bash
# Check entire workspace
cargo check --workspace
# Build example application
cd examples/leptos
cargo build
# Run tests
cargo test
```
#### **Step 4.2: Runtime Testing**
```bash
# Start development server
cd examples/leptos
trunk serve
# Verify components render correctly
# Test interactive functionality
# Check browser console for errors
```
## 🛠️ **TROUBLESHOOTING CHECKLIST**
### **Before Starting**
- [ ] Rust toolchain is up to date (1.89.0+)
- [ ] Cargo is up to date (1.89.0+)
- [ ] All changes are committed to version control
### **During Implementation**
- [ ] Workspace dependencies updated to 0.8.8
- [ ] Cargo.lock removed and regenerated
- [ ] All component packages use `leptos.workspace = true`
- [ ] Component compilation errors fixed
- [ ] Example application compiles successfully
### **After Implementation**
- [ ] `cargo check --workspace` passes
- [ ] Example application builds without errors
- [ ] Demo renders correctly in browser
- [ ] No console errors or warnings
- [ ] All components function as expected
## 🔧 **COMMON ISSUES AND SOLUTIONS**
### **Issue 1: "expected a tuple with 3 elements, found one with 5 elements"**
**Cause**: Mixed Leptos versions in dependency tree
**Solution**: Clean Cargo.lock and ensure all packages use workspace versions
### **Issue 2: "closure only implements FnOnce"**
**Cause**: Moving values into closures that need to be `FnMut`
**Solution**: Clone values before moving into closures
### **Issue 3: "mismatched types" in view! macros**
**Cause**: Inconsistent return types between components
**Solution**: Use consistent `impl IntoView` return types
### **Issue 4: "unresolved import" errors**
**Cause**: Incorrect import paths or missing dependencies
**Solution**: Verify import paths and ensure all dependencies are properly declared
## 📋 **VERIFICATION COMMANDS**
```bash
# Check current Leptos version in use
cargo tree -p leptos
# Verify all packages use workspace versions
grep -r "leptos = " packages/leptos/*/Cargo.toml
# Check for version conflicts
cargo check --workspace 2>&1 | grep -i "version"
# Verify example compiles
cd examples/leptos && cargo check
```
## 🎯 **SUCCESS CRITERIA**
The migration is successful when:
1. ✅ `cargo check --workspace` completes without errors
2. ✅ Example application compiles successfully
3. ✅ Demo renders correctly in browser
4. ✅ All components function as expected
5. ✅ No version conflicts in dependency tree
6. ✅ Consistent Leptos 0.8.8 usage throughout project

# Testing Infrastructure Documentation
This document provides a comprehensive overview of the testing infrastructure for the Rust shadcn/ui project, with a focus on the radio-group component as an example.
## Overview
The testing infrastructure is designed to ensure component quality, cross-framework parity, and maintainability across all supported Rust web frameworks. It consists of multiple layers of testing:
1. **Unit Tests** - Framework-specific component tests
2. **Integration Tests** - Cross-framework parity and consistency tests
3. **Accessibility Tests** - ARIA compliance and usability tests
4. **Theme Tests** - Visual consistency across design variants
5. **Build Tests** - Compilation and dependency validation
## Architecture
### Test Utilities (`packages/test-utils`)
The test utilities package provides shared testing infrastructure:
```rust
use shadcn_ui_test_utils::{
ComponentTester, ComponentComparator, ParityChecker,
Framework, Theme, FrameworkImplementation, ComponentSpec, PropSpec
};
```
#### Core Components
- **`ComponentTester`** - Validates individual component behavior
- **`ComponentComparator`** - Compares implementations across frameworks
- **`ParityChecker`** - Ensures API and feature parity
- **`ThemeValidator`** - Validates theme consistency
- **`VisualRegression`** - Visual regression testing (planned)
### Framework Support
```rust
#[derive(Debug, Clone, PartialEq, Eq, Hash)]
pub enum Framework {
Leptos,
Yew,
Dioxus, // Planned
}
```
### Theme Variants
```rust
#[derive(Debug, Clone, PartialEq)]
pub enum Theme {
Default,
NewYork,
}
```
## Testing Layers
### 1. Unit Tests
Unit tests are framework-specific and test individual component functionality.
#### Yew Unit Tests
```rust
#[wasm_bindgen_test]
fn test_radio_group_renders() {
let rendered = yew::start_app_with_props::<RadioGroup>(RadioGroupProps {
value: Some("option1".to_string()),
on_value_change: None,
disabled: false,
// ... other props
});
let container = rendered.query_selector("[role='radiogroup']").unwrap();
assert!(container.is_some(), "Radio group should have role='radiogroup'");
}
```
#### Leptos Unit Tests
```rust
#[wasm_bindgen_test]
fn test_radio_group_renders() {
let (selected_value, _) = create_signal(None::<String>);
let rendered = mount_to_body(|| {
view! {
<RadioGroup value=selected_value>
<RadioGroupItem value="option1".to_string()>
"Option 1"
</RadioGroupItem>
</RadioGroup>
}
});
let container = web_sys::window()
.unwrap()
.document()
.unwrap()
.query_selector("[role='radiogroup']")
.unwrap();
assert!(container.is_some(), "Radio group should have role='radiogroup'");
}
```
### 2. Integration Tests
Integration tests ensure cross-framework parity and consistency.
```rust
#[test]
fn test_radio_group_cross_framework_parity() {
let mut props = HashMap::new();
props.insert("value".to_string(), PropSpec {
prop_type: "Option<String>".to_string(),
required: false,
default_value: Some("None".to_string()),
});
// ... more props
let radio_group_spec = ComponentSpec {
name: "RadioGroup".to_string(),
props,
events: vec!["on_value_change".to_string()],
variants: vec!["Default".to_string(), "NewYork".to_string()],
sizes: vec![],
};
let yew_impl = FrameworkImplementation {
framework: Framework::Yew,
component_spec: radio_group_spec.clone(),
css_classes: vec![
"grid".to_string(),
"gap-2".to_string(),
// ... more classes
],
dependencies: vec!["yew".to_string(), "yew_style".to_string()],
};
let leptos_impl = FrameworkImplementation {
framework: Framework::Leptos,
component_spec: radio_group_spec,
css_classes: vec![
"grid".to_string(),
"gap-2".to_string(),
// ... more classes
],
dependencies: vec!["leptos".to_string(), "leptos_style".to_string()],
};
let checker = ParityChecker::new()
.add_implementation(yew_impl)
.add_implementation(leptos_impl);
let api_result = checker.check_api_parity();
assert!(api_result.frameworks_match, "RadioGroup API should match across frameworks");
assert_eq!(api_result.score, 1.0, "RadioGroup should have perfect parity score");
}
```
### 3. Accessibility Tests
Accessibility tests ensure ARIA compliance and usability.
```rust
#[test]
fn test_radio_group_accessibility_features() {
let yew_tester = ComponentTester::new("radio-group", Framework::Yew)
.with_theme(Theme::Default)
.with_property("value", "option1")
.with_property("disabled", "false");
let leptos_tester = ComponentTester::new("radio-group", Framework::Leptos)
.with_theme(Theme::Default)
.with_property("value", "option1")
.with_property("disabled", "false");
// Test accessibility features
let yew_accessibility = yew_tester.test_accessibility();
assert!(yew_accessibility.passed, "Yew RadioGroup should be accessible");
let leptos_accessibility = leptos_tester.test_accessibility();
assert!(leptos_accessibility.passed, "Leptos RadioGroup should be accessible");
}
```
### 4. Theme Tests
Theme tests validate visual consistency across design variants.
```rust
#[test]
fn test_radio_group_theme_consistency() {
let validator = ThemeValidator::new()
.add_component_classes("radio-group", vec![
"grid".to_string(),
"gap-2".to_string(),
])
.add_component_classes("radio-group-item", vec![
"aspect-square".to_string(),
"h-4".to_string(),
"w-4".to_string(),
"rounded-full".to_string(),
"border".to_string(),
"border-primary".to_string(),
"text-primary".to_string(),
// ... more classes
]);
let default_result = validator.validate_theme_classes("radio-group", Theme::Default);
assert!(default_result.passed, "RadioGroup should have valid default theme classes");
let new_york_result = validator.validate_theme_classes("radio-group", Theme::NewYork);
assert!(new_york_result.passed, "RadioGroup should have valid New York theme classes");
}
```

# Testing Strategy for Rust shadcn/ui
## Current State Analysis
### **✅ Existing Infrastructure**
- **No current test files** found in the project
- **WASM-capable dependencies** already configured (web-sys, wasm-bindgen)
- **Component architecture** well-structured for testing
- **Workspace configuration** supports test dependencies
### **🔍 Testing Challenges Identified**
- **Cross-Framework Testing**: Leptos vs Yew implementations need identical behavior
- **WASM Testing Environment**: Browser-based component testing complexity
- **Theme Consistency**: Visual regression testing across Default/New York themes
- **Component Parity**: Ensuring feature equivalence between frameworks
- **CLI Integration**: Testing component generation and installation
## 🎯 **Multi-Layer Testing Strategy**
### **Layer 1: Unit Tests (Rust Native)**
```rust
// Component logic testing
#[cfg(test)]
mod tests {
use super::*;
#[test]
fn button_class_generation() {
let class = ButtonClass {
variant: ButtonVariant::Primary,
size: ButtonSize::Default,
};
assert!(class.to_string().contains("bg-primary"));
}
#[test]
fn props_validation() {
let props = ButtonProps {
disabled: true,
variant: ButtonVariant::Destructive,
..Default::default()
};
// Test prop combinations and validation
}
}
```
### **Layer 2: Component Integration Tests (WASM)**
```rust
// WASM-based component rendering tests
#[cfg(test)]
mod integration_tests {
use wasm_bindgen_test::*;
wasm_bindgen_test_configure!(run_in_browser);
#[wasm_bindgen_test]
fn button_renders_correctly() {
// Test component rendering in browser environment
}
#[wasm_bindgen_test]
fn event_handlers_work() {
// Test user interactions and callbacks
}
}
```
### **Layer 3: Cross-Framework Parity Tests**
```rust
// Ensure Leptos and Yew components behave identically
#[cfg(test)]
mod parity_tests {
#[test]
fn leptos_yew_props_equivalence() {
// Compare component APIs
}
#[test]
fn theme_output_consistency() {
// Verify same theme generates same CSS classes
}
}
```
### **Layer 4: Visual Regression Tests (Browser)**
```javascript
// Playwright-based visual testing
describe('Button Component', () => {
test('visual consistency across themes', async ({ page }) => {
await page.goto('/components/button');
await expect(page.locator('.button-default')).toHaveScreenshot();
await expect(page.locator('.button-new-york')).toHaveScreenshot();
});
});
```
### **Layer 5: End-to-End CLI Tests**
```bash
# CLI functionality testing
cargo test --bin rust-shadcn -- --test-threads=1
```

npx playwright test tests/e2e/dynamic-loading.spec.ts --ui
```
## 🧪 Test Development
### **Adding New Tests**
1. **Identify the feature** to test
2. **Choose the appropriate test suite** (dynamic-loading or bundle-optimization)
3. **Follow the existing pattern** for test structure
4. **Use descriptive test names** that explain the expected behavior
5. **Include proper assertions** for all important aspects
### **Test Structure Pattern**
```typescript
test.describe('Feature Category', () => {
test('should perform expected behavior', async ({ page }) => {
// Arrange: Set up test conditions
await page.goto('http://127.0.0.1:8080');
// Act: Perform the action being tested
await page.click('.load-component-btn');
// Assert: Verify the expected outcome
await expect(page.locator('.component-success')).toBeVisible();
});
});
```
### **Best Practices**
- **Use descriptive test names** that explain the expected behavior
- **Test one concept per test** for easier debugging
- **Include proper timeouts** for async operations
- **Use page object patterns** for complex selectors
- **Test both positive and negative scenarios**
- **Verify accessibility** in every test
## 🚨 Troubleshooting
### **Common Issues**
#### **Server Not Running**
```bash
# Error: "could not find the root package of the target crate"
# Solution: Run from correct directory
cd book-examples/leptos
trunk serve
```
#### **WASM Loading Issues**
```bash
# Error: "WASM bindings not found"
# Solution: Wait for WASM initialization
await page.waitForFunction(() => window.wasmBindings !== undefined);
```
#### **Component Loading Timeouts**
```bash
# Error: "Component loading timeout"
# Solution: Increase timeout for slow operations
await expect(element).toBeVisible({ timeout: 15000 });
```
#### **Playwright Installation Issues**
```bash
# Error: "Playwright not found"
# Solution: Install and setup Playwright
npm install -D @playwright/test
npx playwright install
```
### **Performance Issues**
- **Slow test execution**: Check if development server is responsive
- **Memory issues**: Verify no memory leaks in component loading
- **Timeout errors**: Adjust timeouts for slower environments
