# AGENTS.md - Development Guide for leptos-shadcn-ui
## Build/Test Commands
- **Build**: `cargo build --workspace` (or `make build`)
- **Test workspace**: `cargo test --workspace --lib` (or `make test-rust`)
- **Test single component**: `cargo test -p leptos-shadcn-<component>` (e.g., `cargo test -p leptos-shadcn-button`)
- **Test with verbose**: `RUST_LOG=debug cargo test --workspace --lib -- --nocapture`
- **E2E tests**: `make test-e2e` or `pnpm playwright test`
- **Lint**: `cargo clippy --workspace -- -D warnings` (or `make lint`)
- **Format**: `cargo fmt --all` (or `make fmt`)
- **Check**: `cargo check --workspace` (or `make check`)
## Architecture
- **Workspace**: Monorepo with packages in `packages/leptos/` for components
- **Components**: 46 ShadCN UI components for Leptos v0.8+
- **Structure**: Each component has lib.rs, default.rs, new_york.rs, signal_managed.rs, tests.rs
- **Testing**: TDD-focused with separate test modules in `src/tdd_tests/`
- **Performance**: Includes performance-audit system and benchmarking
## Code Style
- **Imports**: Leptos imports first (`use leptos::prelude::*;`), then utilities, external crates, internal
- **Naming**: kebab-case packages, PascalCase components, snake_case functions, SCREAMING_SNAKE_CASE constants
- **Components**: Use `#[component]` with optional props via `MaybeProp<T>`, `Option<Callback<T>>` for events
- **Props**: Standard props are `class`, `id`, `style`, `children`, with `#[prop(into, optional)]`
- **Errors**: Use validation system with `ValidationRule`, comprehensive error boundaries
- **Derive**: Standard order `#[derive(Debug, Clone, PartialEq)]` for most types
- **CSS**: Define class constants, use Signal::derive for dynamic classes
- **Documentation**: Module docs with `//!`, inline comments for accessibility and TDD enhancements

@@ -79,6 +79,93 @@ This document outlines a comprehensive 4-week plan to achieve 90%+ test coverage
**Status**: ✅ **COMPLETED** - Added 44 comprehensive implementation tests covering validation system, input types, accessibility, form integration, and edge cases.
## Signal Management Test Fixes - Session 5 Update
### Progress Summary
**Date**: Current Session
**Focus**: Signal Management Test Error Resolution
**Approach**: Targeted Manual Fixes
### Error Reduction Progress
- **Initial State**: 500 test errors
- **Current State**: 271 test errors
- **Total Fixed**: 229 errors (46% reduction)
- **Remaining**: 271 errors
### Key Fixes Applied
#### 1. Queue Update API Alignment
**Issue**: Tests were using incorrect `queue_update` API calls
**Solution**: Converted from `queue_update(signal, value)` to proper closure-based calls
**Files Fixed**:
- `packages/signal-management/src/simple_tests/batched_updates_tests.rs`
- `packages/signal-management/src/signal_management_tests/batched_updates_tests.rs`
- `packages/signal-management/src/signal_management_tests/performance_tests.rs`
**Example Fix**:
```rust
// Before (incorrect)
updater.queue_update(signal.clone(), "update1".to_string());
// After (correct)
let signal_clone = signal.clone();
updater.queue_update(move || {
signal_clone.set("update1".to_string());
}).unwrap();
```
#### 2. Missing Method Implementation
**Issue**: Tests calling non-existent `get_group()` method
**Solution**: Added missing method to `SignalMemoryManager`
**Implementation**:
```rust
/// Get a specific group by name
pub fn get_group(&self, group_name: &str) -> Option<SignalGroup> {
self.tracked_groups.with(|groups| {
groups.get(group_name).cloned()
})
}
```
#### 3. Moved Value Issues
**Issue**: `cleanup.cleanup()` takes ownership, but tests try to use cleanup afterwards
**Solution**: Clone cleanup before calling cleanup method
**Pattern**:
```rust
// Before (causes moved value error)
cleanup.cleanup();
assert_eq!(cleanup.signals_count(), 0);
// After (fixed)
cleanup.clone().cleanup();
assert_eq!(cleanup.signals_count(), 0);
```
### Error Pattern Analysis
**Remaining Error Types**:
1. **Type Mismatches** (49 errors) - String literal type issues
2. **Moved Value Issues** (48 errors) - Ownership problems with cleanup
3. **Type Comparisons** (12 errors) - f64 vs integer comparisons
4. **Missing Methods** (13 errors) - API mismatches
### Strategy Refinements
1. **Targeted Manual Fixes**: Avoid broad batch operations that introduce new issues
2. **Systematic Approach**: Fix one error pattern at a time
3. **Validation**: Test progress after each set of fixes
4. **Revert When Needed**: Use git to revert problematic changes
### Next Steps
1. **Continue Moved Value Fixes**: Address remaining cleanup ownership issues
2. **Type Comparison Fixes**: Convert integer comparisons to float comparisons
3. **Missing Method Implementation**: Add remaining missing API methods
4. **Type Mismatch Resolution**: Fix string literal type issues
### Lessons Learned
1. **Batch Operations Risk**: sed commands can introduce syntax errors
2. **Manual Approach Works**: Targeted fixes are more reliable
3. **Progress Tracking**: Regular error count monitoring is essential
4. **Git Safety Net**: Reverting problematic changes maintains progress
#### Day 5-7: Card Component Enhancement
**Current**: 71.4% coverage (90/126 lines)
**Target**: 85% coverage (107/126 lines)

# Button Component Design Specification
## Overview & Purpose
The Button component is the primary interactive element for triggering actions in the UI. It serves as the foundation for user interactions and must be highly reliable, accessible, and performant.
**Component Type**: Interactive/Action
**Priority**: P0 (Critical - used everywhere)
**Dependencies**: None (foundation component)
## API Specification
### Props Interface
```rust
#[derive(Props, PartialEq)]
pub struct ButtonProps {
/// Visual style variant
#[prop(into, optional)]
pub variant: MaybeProp<ButtonVariant>,
/// Size variant
#[prop(into, optional)]
pub size: MaybeProp<ButtonSize>,
/// Click event handler
#[prop(optional)]
pub on_click: Option<Callback<web_sys::MouseEvent>>,
/// Disabled state
#[prop(into, optional)]
pub disabled: MaybeProp<bool>,
/// Loading state with spinner
#[prop(into, optional)]
pub loading: MaybeProp<bool>,
/// HTML type attribute
#[prop(into, optional)]
pub button_type: MaybeProp<String>,
/// Custom CSS classes
#[prop(into, optional)]
pub class: MaybeProp<String>,
/// HTML id attribute
#[prop(into, optional)]
pub id: MaybeProp<String>,
/// Inline styles
#[prop(into, optional)]
pub style: MaybeProp<String>,
/// Button content
#[prop(optional)]
pub children: Option<Children>,
}
```
### Enums
```rust
#[derive(Debug, Clone, PartialEq)]
pub enum ButtonVariant {
Default, // Primary action (blue)
Destructive, // Dangerous actions (red)
Outline, // Secondary action (outlined)
Secondary, // Tertiary action (muted)
Ghost, // Minimal styling (transparent)
Link, // Link-style button (underlined)
}
#[derive(Debug, Clone, PartialEq)]
pub enum ButtonSize {
Default, // Standard size (px-4 py-2)
Small, // Compact size (px-3 py-1.5)
Large, // Prominent size (px-8 py-3)
Icon, // Square icon button (p-2)
}
```
## Behavioral Requirements
### Core Behaviors
1. **Click Handling**: Executes `on_click` callback when activated
2. **Keyboard Support**: Responds to Enter and Space keys
3. **Focus Management**: Proper focus indicators and tab order
4. **Disabled State**: Prevents interaction and shows disabled styling
5. **Loading State**: Shows spinner and prevents additional clicks
### State Transitions
```
[Idle] --click--> [Processing] --complete--> [Idle]
[Idle] --disabled--> [Disabled] --enabled--> [Idle]
[Any State] --loading--> [Loading] --complete--> [Previous State]
```
### Event Handling
- **Mouse Events**: click, mousedown, mouseup, mouseenter, mouseleave
- **Keyboard Events**: keydown (Enter/Space), keyup
- **Focus Events**: focus, blur, focusin, focusout
- **Touch Events**: touchstart, touchend (mobile support)
## Accessibility Requirements
### WCAG 2.1 AA Compliance
- **Role**: Implicit `button` role (or explicit if needed)
- **Labels**: Accessible name via content or `aria-label`
- **States**: `aria-disabled`, `aria-pressed` for toggle buttons
- **Focus**: Visible focus indicator (2px outline)
- **Contrast**: 4.5:1 minimum for text, 3:1 for non-text
### Keyboard Navigation
- **Tab**: Focuses the button
- **Enter/Space**: Activates the button
- **Escape**: Cancels focus (in some contexts)
### Screen Reader Support
```html
<button
type="button"
aria-label="Save changes"
aria-disabled="false"
aria-describedby="save-help-text">
Save
</button>
```
## Styling & Theming
### Base Styles
```rust
const BASE_CLASSES: &str = "inline-flex items-center justify-center whitespace-nowrap rounded-md text-sm font-medium ring-offset-background transition-colors focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2 disabled:pointer-events-none disabled:opacity-50";
```
### Variant Styles
```rust
fn variant_classes(variant: ButtonVariant) -> &'static str {
match variant {
ButtonVariant::Default => "bg-primary text-primary-foreground hover:bg-primary/90",
ButtonVariant::Destructive => "bg-destructive text-destructive-foreground hover:bg-destructive/90",
ButtonVariant::Outline => "border border-input bg-background hover:bg-accent hover:text-accent-foreground",
ButtonVariant::Secondary => "bg-secondary text-secondary-foreground hover:bg-secondary/80",
ButtonVariant::Ghost => "hover:bg-accent hover:text-accent-foreground",
ButtonVariant::Link => "text-primary underline-offset-4 hover:underline",
}
}
```
### Size Classes
```rust
fn size_classes(size: ButtonSize) -> &'static str {
match size {
ButtonSize::Default => "h-10 px-4 py-2",
ButtonSize::Small => "h-9 rounded-md px-3 text-xs",
ButtonSize::Large => "h-11 rounded-md px-8",
ButtonSize::Icon => "h-10 w-10",
}
}
```
### Loading State
```rust
// Add spinner component when loading=true
view! {
<button class=computed_classes disabled=is_loading_or_disabled>
{move || if loading.get() {
view! { <Spinner class="mr-2 h-4 w-4" /> }.into_any()
} else {
children.into_any()
}}
</button>
}
```
## Testing Strategy
### Unit Tests
```rust
#[cfg(test)]
mod tests {
use super::*;
use leptos_testing::*;
#[wasm_bindgen_test]
fn renders_default_button() {
let result = render_component(|| {
view! { <Button>"Click me"</Button> }
});
assert_element_exists(&result, "button");
assert_element_text(&result, "button", "Click me");
assert_element_has_class(&result, "button", "bg-primary");
}
#[wasm_bindgen_test]
fn handles_click_events() {
let clicked = create_rw_signal(false);
let result = render_component(|| {
view! {
<Button on_click=move |_| clicked.set(true)>
"Click me"
</Button>
}
});
click_element(&result, "button");
assert!(clicked.get());
}
#[wasm_bindgen_test]
fn disables_when_disabled_prop_true() {
let result = render_component(|| {
view! { <Button disabled=true>"Disabled"</Button> }
});
assert_element_disabled(&result, "button");
assert_element_has_class(&result, "button", "opacity-50");
}
}
```
### Integration Tests
- Form submission integration
- Modal dialog integration
- Navigation integration
- Loading state management
### Accessibility Tests
```rust
#[wasm_bindgen_test]
async fn meets_accessibility_standards() {
let result = render_component(|| {
view! { <Button>"Accessible button"</Button> }
});
// Run axe-core accessibility checks
assert_accessible(&result).await;
// Test keyboard navigation
assert_focusable(&result, "button");
assert_activates_on_enter(&result, "button");
assert_activates_on_space(&result, "button");
}
```
### Performance Tests
```rust
#[wasm_bindgen_test]
fn renders_within_performance_budget() {
let start = performance::now();
let _result = render_component(|| {
view! { <Button>"Performance test"</Button> }
});
let duration = performance::now() - start;
assert!(duration < 16.0, "Button should render in <16ms");
}
```
## Implementation Notes
### State Management
- Use `create_rw_signal` for internal state (focus, hover)
- Props should be reactive via `MaybeProp<T>`
- Memoize computed classes with `create_memo`
### Event Handling Best Practices
```rust
let handle_click = move |event: web_sys::MouseEvent| {
if disabled.get() || loading.get() {
return;
}
if let Some(on_click) = on_click {
on_click.call(event);
}
};
```
### Bundle Size Considerations
- Import only necessary Tailwind classes
- Use const strings for common class combinations
- Avoid large dependency trees
### Performance Optimizations
- Memoize class computation
- Use `Signal::derive` for reactive styling
- Minimal re-renders on prop changes
## Examples & Usage
### Basic Usage
```rust
view! {
<Button on_click=|_| console::log!("Clicked!")>
"Click me"
</Button>
}
```
### Variants Showcase
```rust
view! {
<div class="space-y-2">
<Button variant=ButtonVariant::Default>"Primary"</Button>
<Button variant=ButtonVariant::Destructive>"Delete"</Button>
<Button variant=ButtonVariant::Outline>"Cancel"</Button>
<Button variant=ButtonVariant::Ghost>"Ghost"</Button>
<Button variant=ButtonVariant::Link>"Link style"</Button>
</div>
}
```
### Loading State
```rust
fn LoadingExample() -> impl IntoView {
let loading = create_rw_signal(false);
view! {
<Button
loading=loading.get()
on_click=move |_| {
loading.set(true);
// Simulate async operation
set_timeout(
move || loading.set(false),
Duration::from_secs(2)
);
}
>
"Save Changes"
</Button>
}
}
```
### Form Integration
```rust
view! {
<form on_submit=handle_submit>
<Button button_type="submit" disabled=form_invalid>
"Submit Form"
</Button>
</form>
}
```
### Icon Button
```rust
view! {
<Button
size=ButtonSize::Icon
variant=ButtonVariant::Ghost
aria_label="Close dialog"
>
<Icon name="x" />
</Button>
}
```
## Migration Notes
### From v0.3.x to v0.4.x
- `onClick` prop renamed to `on_click`
- `variant` prop now uses enum instead of string
- `loading` prop added for async operations
### Breaking Changes
- Removed `asChild` prop (use composition instead)
- Size prop values changed (sm/md/lg → Small/Default/Large)

# Input Component Design Specification
## Overview & Purpose
The Input component is a foundational form element that handles text input with comprehensive validation, accessibility features, and integration with form libraries. It serves as the base for all text-based form interactions.
**Component Type**: Form/Input
**Priority**: P0 (Critical - essential for forms)
**Dependencies**: Label (optional), ValidationContext
## API Specification
### Props Interface
```rust
#[derive(Props, PartialEq)]
pub struct InputProps {
/// Input type (text, email, password, etc.)
#[prop(into, optional)]
pub input_type: MaybeProp<InputType>,
/// Current value
#[prop(into, optional)]
pub value: MaybeProp<String>,
/// Placeholder text
#[prop(into, optional)]
pub placeholder: MaybeProp<String>,
/// Disabled state
#[prop(into, optional)]
pub disabled: MaybeProp<bool>,
/// Required field indicator
#[prop(into, optional)]
pub required: MaybeProp<bool>,
/// Readonly state
#[prop(into, optional)]
pub readonly: MaybeProp<bool>,
/// Input change handler
#[prop(optional)]
pub on_input: Option<Callback<String>>,
/// Focus event handler
#[prop(optional)]
pub on_focus: Option<Callback<web_sys::FocusEvent>>,
/// Blur event handler (validation trigger)
#[prop(optional)]
pub on_blur: Option<Callback<web_sys::FocusEvent>>,
/// Validation rules
#[prop(optional)]
pub validator: Option<InputValidator>,
/// Error state override
#[prop(into, optional)]
pub error: MaybeProp<Option<String>>,
/// Success state override
#[prop(into, optional)]
pub success: MaybeProp<bool>,
/// Custom CSS classes
#[prop(into, optional)]
pub class: MaybeProp<String>,
/// HTML id attribute
#[prop(into, optional)]
pub id: MaybeProp<String>,
/// HTML name attribute (form binding)
#[prop(into, optional)]
pub name: MaybeProp<String>,
/// ARIA label for accessibility
#[prop(into, optional)]
pub aria_label: MaybeProp<String>,
/// ARIA described by (error messages)
#[prop(into, optional)]
pub aria_describedby: MaybeProp<String>,
}
```
### Enums and Types
```rust
#[derive(Debug, Clone, PartialEq)]
pub enum InputType {
Text,
Email,
Password,
Tel,
Url,
Search,
Number,
}
impl Default for InputType {
fn default() -> Self {
Self::Text
}
}
#[derive(Debug, Clone, PartialEq)]
pub enum InputSize {
Small, // Compact form inputs
Default, // Standard size
Large, // Prominent inputs
}
#[derive(Debug, Clone)]
pub struct InputValidator {
pub rules: Vec<ValidationRule>,
pub on_validation: Option<Callback<ValidationResult>>,
}
#[derive(Debug, Clone, PartialEq)]
pub enum ValidationRule {
Required,
MinLength(usize),
MaxLength(usize),
Email,
Pattern(String),
Custom(fn(&str) -> Result<(), String>),
}
#[derive(Debug, Clone, PartialEq)]
pub struct ValidationResult {
pub is_valid: bool,
pub errors: Vec<String>,
pub field_name: String,
}
```
## Behavioral Requirements
### Core Behaviors
1. **Text Input**: Accepts and displays user text input
2. **Real-time Validation**: Validates on input/blur based on rules
3. **State Management**: Tracks focus, error, success states
4. **Form Integration**: Works with form libraries and native forms
5. **Accessibility**: Full screen reader and keyboard support
### State Transitions
```
[Empty] --input--> [Filled] --validate--> [Valid/Invalid]
[Any] --focus--> [Focused] --blur--> [Unfocused + Validated]
[Any] --disabled--> [Disabled] --enabled--> [Previous State]
```
### Validation Timing
- **On Input**: Real-time for immediate feedback (debounced 300ms)
- **On Blur**: Comprehensive validation when field loses focus
- **On Submit**: Final validation before form submission
- **On Mount**: Initial validation if value provided
### Event Handling
```rust
// Input event with debouncing
let handle_input = move |event: web_sys::Event| {
let input = event_target_value(&event);
value_signal.set(input.clone());
// Debounced validation
debounced_validate.call(input);
if let Some(on_input) = on_input {
on_input.call(input);
}
};
// Blur event for validation
let handle_blur = move |event: web_sys::FocusEvent| {
set_focused(false);
validate_field();
if let Some(on_blur) = on_blur {
on_blur.call(event);
}
};
```
## Accessibility Requirements
### WCAG 2.1 AA Compliance
- **Labels**: Associated with `<label>` element or `aria-label`
- **Error Messages**: Linked via `aria-describedby`
- **Required Fields**: Indicated with `required` attribute and `aria-required`
- **Invalid State**: Marked with `aria-invalid="true"`
- **Focus Management**: Clear focus indicators and logical tab order
### Screen Reader Support
```html
<div>
<label for="email-input" class="sr-only">Email Address</label>
<input
type="email"
id="email-input"
name="email"
placeholder="Enter email address"
required
aria-required="true"
aria-invalid="false"
aria-describedby="email-error email-help"
/>
<div id="email-help" class="sr-only">
We'll never share your email address
</div>
<div id="email-error" role="alert" aria-live="polite">
<!-- Error messages inserted here -->
</div>
</div>
```
### Keyboard Navigation
- **Tab**: Focuses the input field
- **Enter**: Submits parent form (if applicable)
- **Escape**: Clears field (optional behavior)
## Styling & Theming
### Base Styles
```rust
const BASE_CLASSES: &str = "flex h-10 w-full rounded-md border border-input bg-background px-3 py-2 text-sm ring-offset-background file:border-0 file:bg-transparent file:text-sm file:font-medium placeholder:text-muted-foreground focus-visible:outline-none focus-visible:ring-2 focus-visible:ring-ring focus-visible:ring-offset-2 disabled:cursor-not-allowed disabled:opacity-50";
```
### State-based Styles
```rust
fn input_classes(
has_error: bool,
has_success: bool,
is_focused: bool,
disabled: bool,
) -> String {
let mut classes = vec![BASE_CLASSES];
match (has_error, has_success, disabled) {
(true, _, false) => classes.push("border-destructive focus-visible:ring-destructive"),
(false, true, false) => classes.push("border-success focus-visible:ring-success"),
(_, _, true) => classes.push("border-muted bg-muted"),
_ => {}
}
if is_focused && !disabled {
classes.push("ring-2 ring-ring ring-offset-2");
}
classes.join(" ")
}
```
### Size Variants
```rust
fn size_classes(size: InputSize) -> &'static str {
match size {
InputSize::Small => "h-8 px-2 py-1 text-xs",
InputSize::Default => "h-10 px-3 py-2 text-sm",
InputSize::Large => "h-12 px-4 py-3 text-base",
}
}
```
## Testing Strategy
### Unit Tests
```rust
#[cfg(test)]
mod tests {
use super::*;
use leptos_testing::*;
#[wasm_bindgen_test]
fn renders_basic_input() {
let result = render_component(|| {
view! { <Input placeholder="Enter text" /> }
});
assert_element_exists(&result, "input");
assert_element_attribute(&result, "input", "placeholder", "Enter text");
assert_element_has_class(&result, "input", "border-input");
}
#[wasm_bindgen_test]
fn handles_input_events() {
let value = create_rw_signal(String::new());
let result = render_component(|| {
view! {
<Input
value=value.get()
on_input=move |v| value.set(v)
/>
}
});
type_in_element(&result, "input", "Hello World");
assert_eq!(value.get(), "Hello World");
}
#[wasm_bindgen_test]
fn validates_required_field() {
let validator = InputValidator::new()
.required()
.build();
let result = render_component(|| {
view! {
<Input
validator=validator
value=""
/>
}
});
blur_element(&result, "input");
assert_element_has_attribute(&result, "input", "aria-invalid", "true");
assert_element_exists(&result, "[role='alert']");
}
#[wasm_bindgen_test]
fn validates_email_format() {
let validator = InputValidator::new()
.email()
.build();
let result = render_component(|| {
view! {
<Input
input_type=InputType::Email
validator=validator
value="invalid-email"
/>
}
});
blur_element(&result, "input");
assert_element_has_attribute(&result, "input", "aria-invalid", "true");
assert_element_text_contains(&result, "[role='alert']", "valid email");
}
}
```
### Integration Tests
```rust
#[wasm_bindgen_test]
async fn integrates_with_form() {
let form_submitted = create_rw_signal(false);
let result = render_component(|| {
view! {
<form on_submit=move |e| {
e.prevent_default();
form_submitted.set(true);
}>
<Input name="username" required=true />
<button type="submit">"Submit"</button>
</form>
}
});
type_in_element(&result, "input", "testuser");
click_element(&result, "button");
assert!(form_submitted.get());
}
```
### Accessibility Tests
```rust
#[wasm_bindgen_test]
async fn meets_accessibility_standards() {
let result = render_component(|| {
view! {
<div>
<label for="test-input">"Test Input"</label>
<Input id="test-input" required=true />
</div>
}
});
// Run axe-core checks
assert_accessible(&result).await;
// Test specific a11y requirements
assert_element_has_attribute(&result, "input", "aria-required", "true");
assert_elements_associated(&result, "label", "input");
}
```
### Performance Tests
```rust
#[wasm_bindgen_test]
fn handles_rapid_input_efficiently() {
let result = render_component(|| {
view! { <Input validator=complex_validator /> }
});
let start = performance::now();
// Simulate rapid typing
for i in 0..100 {
type_in_element(&result, "input", &format!("text{}", i));
}
let duration = performance::now() - start;
assert!(duration < 1000.0, "Should handle rapid input in <1s");
}
```
## Implementation Notes
### Debounced Validation
```rust
fn create_debounced_validator(
validator: Option<InputValidator>,
delay_ms: u32,
) -> impl Fn(String) {
let timeout_handle = create_rw_signal(None::<i32>);
move |value: String| {
// Clear existing timeout
if let Some(handle) = timeout_handle.get() {
clear_timeout(handle);
}
// Set new timeout
let new_handle = set_timeout(
move || validate_value(value.clone(), &validator),
delay_ms,
);
timeout_handle.set(Some(new_handle));
}
}
```
### Form Integration
```rust
impl Input {
// Register with form context on mount
fn register_with_form(&self) {
if let Some(form_context) = use_context::<FormContext>() {
form_context.register_field(FormField {
name: self.name.clone(),
value: self.value_signal,
validator: self.validator.clone(),
errors: self.errors_signal,
});
}
}
}
```
### Memory Management
- Use `create_memo` for computed validation state
- Clean up event listeners on unmount
- Debounce validation to prevent excessive calls
## Examples & Usage
### Basic Text Input
```rust
view! {
<Input
placeholder="Enter your name"
on_input=move |value| console::log!("Input: {}", value)
/>
}
```
### Email Input with Validation
```rust
let email_validator = InputValidator::new()
.required()
.email()
.build();
view! {
<Input
input_type=InputType::Email
placeholder="your@email.com"
validator=email_validator
required=true
/>
}
```
### Password Input with Strength Validation
```rust
let password_validator = InputValidator::new()
.required()
.min_length(8)
.pattern(r"^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[@$!%*?&])")
.build();
view! {
<Input
input_type=InputType::Password
placeholder="Strong password"
validator=password_validator
/>
}
```
### Controlled Input with External State
```rust
fn ControlledInput() -> impl IntoView {
let value = create_rw_signal(String::new());
let char_count = create_memo(move |_| value.get().len());
view! {
<div>
<Input
value=value.get()
on_input=move |v| value.set(v)
placeholder="Type something..."
/>
<div class="text-sm text-muted-foreground">
{char_count} " characters"
</div>
</div>
}
}
```
### Form Integration Example
```rust
view! {
<form class="space-y-4">
<div>
<label for="username">"Username"</label>
<Input
id="username"
name="username"
required=true
validator=username_validator
/>
</div>
<div>
<label for="email">"Email"</label>
<Input
id="email"
name="email"
input_type=InputType::Email
required=true
validator=email_validator
/>
</div>
<button type="submit">"Submit"</button>
</form>
}
```

# Test Coverage Crisis Remediation
## Issue Summary
**Severity**: 🔴 CRITICAL
**Effort**: 40-60 hours
**Priority**: P0 (Block all other work)
## Problem Description
Repository claims "100% test coverage" but analysis reveals:
- ~170 actual test assertions across entire codebase
- Majority are `assert!(true, "message")` placeholders
- No coverage tooling configured (tarpaulin, llvm-cov)
- Tests don't mount components in DOM
- No WASM test execution in CI
## Root Cause Analysis
1. **Test-Driven Development Theater**: Tests written to satisfy CI without validating functionality
2. **Missing Test Infrastructure**: No proper testing harness for Leptos components
3. **No Coverage Enforcement**: No gates preventing regression
4. **Copy-Paste Testing**: Same placeholder patterns across all components
## Remediation Steps
### Step 1: Audit Current Test Reality (4 hours)
```bash
# Count real vs placeholder tests
find packages/leptos -name "*.rs" -type f -exec grep -l "assert!(true" {} \; | wc -l
find packages/leptos -name "*.rs" -type f -exec grep -l "assert_eq!\|assert_ne!" {} \; | wc -l
# Generate coverage baseline
cargo install cargo-llvm-cov
cargo llvm-cov --html --output-dir coverage-report/
```
### Step 2: Fix Core Component Tests (20-30 hours)
Priority components to fix first:
1. **Button** - Most critical, used everywhere
2. **Input** - Form foundation
3. **Card** - Layout foundation
4. **Badge** - Simple but essential
5. **Label** - Accessibility critical
**Example Real Test (Button)**:
```rust
#[cfg(test)]
mod tests {
use super::*;
use leptos::*;
use wasm_bindgen_test::*;
wasm_bindgen_test_configure!(run_in_browser);
#[wasm_bindgen_test]
fn button_renders_with_text() {
mount_to_body(|| {
view! {
<Button>"Click me"</Button>
}
});
let button = document()
.query_selector("button")
.unwrap()
.unwrap();
assert_eq!(button.text_content().unwrap(), "Click me");
assert!(button.class_list().contains("bg-primary"));
}
#[wasm_bindgen_test]
fn button_handles_click_events() {
let clicked = create_rw_signal(false);
mount_to_body(|| {
view! {
<Button on_click=move |_| clicked.set(true)>
"Click me"
</Button>
}
});
let button = document()
.query_selector("button")
.unwrap()
.unwrap();
button.click();
assert!(clicked.get());
}
}
```
### Step 3: Add Coverage Infrastructure (8 hours)
```toml
# Add to Cargo.toml [dev-dependencies]
wasm-bindgen-test = "0.3"
web-sys = "0.3"
# Add coverage config
[toolchain]
channel = "nightly"
[env]
RUSTFLAGS = "-C instrument-coverage"
```
### Step 4: CI Integration (4-6 hours)
```yaml
# Add to CI pipeline
- name: Generate Coverage
run: |
cargo install cargo-llvm-cov
cargo llvm-cov --workspace --lcov --output-path lcov.info
- name: Upload Coverage
uses: codecov/codecov-action@v3
with:
file: lcov.info
- name: Coverage Gate
run: |
coverage=$(cargo llvm-cov --workspace --summary-only | grep "TOTAL" | awk '{print $10}' | tr -d '%')
if [ $(echo "$coverage < 80" | bc -l) -eq 1 ]; then
echo "Coverage $coverage% below 80% threshold"
exit 1
fi
```
### Step 5: WASM Test Execution (6 hours)
```yaml
- name: Install wasm-pack
run: curl https://rustwasm.github.io/wasm-pack/installer/init.sh -sSf | sh
- name: Run WASM Tests
run: |
for package in packages/leptos/*/; do
cd "$package"
wasm-pack test --headless --chrome
cd -
done
```
## Success Criteria
- [ ] Real coverage report showing actual percentages
- [ ] All placeholder `assert!(true)` tests replaced
- [ ] Core 5 components have 80%+ coverage
- [ ] WASM tests running in CI
- [ ] Coverage gates preventing regression
- [ ] Documentation on how to write proper tests
## Risk Mitigation
- **Risk**: Breaking existing functionality while fixing tests
- **Mitigation**: Fix one component at a time, test in isolation
- **Risk**: WASM test setup complexity
- **Mitigation**: Use proven wasm-bindgen-test patterns
- **Risk**: Performance impact of coverage
- **Mitigation**: Only run coverage on merge requests, not every push
## Dependencies
- Rust 1.70+ for coverage tooling
- Chrome/Firefox for WASM testing
- CI runner with sufficient memory

# File Size Remediation Plan
## Issue Summary
**Severity**: 🟡 HIGH
**Effort**: 20-30 hours
**Priority**: P1 (Blocks testing and LLM comprehension)
## Problem Description
Multiple files exceed 300-line limit, impacting:
- Test granularity and isolation
- LLM context understanding
- Code review efficiency
- Maintainability and debugging
**Files Exceeding Limit**:
- `select/src/implementation_tests.rs` - 891 lines
- `button/src/tests.rs` - 844 lines
- `switch/src/implementation_tests.rs` - 760 lines
- `table/src/data_table.rs` - 689 lines
- Plus 15 more files 500+ lines
## Root Cause Analysis
1. **Monolithic Test Files**: All tests crammed into single files
2. **God Objects**: Complex components not properly decomposed
3. **Copy-Paste Inflation**: Repeated test patterns instead of helpers
4. **Missing Abstractions**: No shared test utilities
## Remediation Strategy
### Phase 1: Test File Decomposition (12-16 hours)
**Break down by test category**:
```
button/src/tests.rs (844 lines) →
├── tests/
│ ├── rendering_tests.rs (~150 lines)
│ ├── interaction_tests.rs (~150 lines)
│ ├── accessibility_tests.rs (~150 lines)
│ ├── variant_tests.rs (~150 lines)
│ ├── edge_case_tests.rs (~150 lines)
│ └── integration_tests.rs (~100 lines)
└── test_utils.rs (~50 lines)
```
**Example Decomposition**:
```rust
// button/src/tests/rendering_tests.rs
use super::super::*;
use crate::test_utils::*;
#[cfg(test)]
mod rendering {
use super::*;
#[wasm_bindgen_test]
fn renders_default_button() {
let result = render_component(|| {
view! { <Button>"Test"</Button> }
});
assert_button_has_class(&result, "bg-primary");
assert_button_text(&result, "Test");
}
// More focused rendering tests...
}
```
### Phase 2: Component Decomposition (8-12 hours)
**Break down large components**:
```
table/src/data_table.rs (689 lines) →
├── components/
│ ├── table_header.rs (~100 lines)
│ ├── table_row.rs (~100 lines)
│ ├── table_cell.rs (~80 lines)
│ ├── table_pagination.rs (~120 lines)
│ └── table_sorting.rs (~100 lines)
├── hooks/
│ ├── use_table_state.rs (~80 lines)
│ └── use_sorting.rs (~60 lines)
└── lib.rs (~60 lines - exports only)
```
### Phase 3: Shared Test Utilities (4-6 hours)
**Create common test infrastructure**:
```rust
// packages/test-utils/src/component_testing.rs
pub fn render_component<F, V>(component: F) -> ComponentTestResult
where
F: Fn() -> V + 'static,
V: IntoView,
{
// Standard component mounting and testing setup
}
pub fn assert_button_has_class(result: &ComponentTestResult, class: &str) {
// Reusable assertion logic
}
pub fn assert_accessibility_compliance(result: &ComponentTestResult) {
// Shared a11y testing
}
```
## Implementation Plan
### Week 1: Critical Test Files
**Day 1-2**: button/src/tests.rs → 6 focused test files
**Day 3-4**: select/src/implementation_tests.rs → category-based split
**Day 5**: switch/src/implementation_tests.rs → interaction focus
### Week 2: Component Architecture
**Day 1-2**: table/src/data_table.rs → component decomposition
**Day 3-4**: Remaining large implementation files
**Day 5**: Shared utilities and cleanup
### File Size Rules Going Forward
```rust
// Add to rustfmt.toml or clippy config
max_lines = 300
// Add to CI checks
- name: Check File Sizes
run: |
large_files=$(find packages/leptos -name "*.rs" -type f -exec wc -l {} + | awk '$1 > 300 {print $2 " has " $1 " lines"}')
if [ -n "$large_files" ]; then
echo "Files exceeding 300 line limit:"
echo "$large_files"
exit 1
fi
```
## Specific File Remediation
### select/implementation_tests.rs (891 lines)
**Split into**:
- `select_rendering_tests.rs` (150 lines)
- `select_option_tests.rs` (150 lines)
- `select_keyboard_tests.rs` (150 lines)
- `select_accessibility_tests.rs` (150 lines)
- `select_performance_tests.rs` (100 lines)
- `select_integration_tests.rs` (150 lines)
### button/tests.rs (844 lines)
**Split into**:
- `button_variants_tests.rs` (200 lines)
- `button_interactions_tests.rs` (200 lines)
- `button_accessibility_tests.rs` (200 lines)
- `button_edge_cases_tests.rs` (200 lines)
### table/data_table.rs (689 lines)
**Architecture refactor**:
- Extract sorting logic → `table_sorting.rs`
- Extract pagination → `table_pagination.rs`
- Extract row rendering → `table_row_renderer.rs`
- Core table logic → max 200 lines
## Success Criteria
- [ ] No files exceed 300 lines
- [ ] Test files split by logical categories
- [ ] Shared test utilities reduce duplication
- [ ] CI enforces line limits going forward
- [ ] Component architecture follows single responsibility
- [ ] Documentation updated for new structure
## Benefits
1. **Better Test Isolation**: Easier to run specific test categories
2. **Improved LLM Context**: Each file fits in model context windows
3. **Faster Code Reviews**: Reviewers can focus on specific areas
4. **Better Test Parallelization**: Categories can run independently
5. **Easier Debugging**: Smaller surface area per file
## Risk Mitigation
- **Risk**: Breaking existing imports during refactor
- **Mitigation**: Use `pub use` re-exports to maintain compatibility
- **Risk**: Test discovery issues after split
- **Mitigation**: Update Cargo.toml test configurations
- **Risk**: Increased compilation time from more files
- **Mitigation**: Profile build times, optimize if needed
## Dependencies
- Working knowledge of Rust module system
- Test infrastructure already in place
- CI pipeline for enforcement
## Owner
**Primary**: Senior Rust Engineer familiar with component architecture
**Secondary**: Test Engineer for test splitting validation
**Reviewer**: Staff Engineer for architectural approval

## 📚 Best Practices
### 1. **Test Strategy**
- Run WASM tests on every component change
- Use parallel execution for faster feedback
- Monitor performance trends over time
- Test on multiple browsers before releases
### 2. **Performance Optimization**
- Set realistic performance thresholds
- Monitor memory usage patterns
- Optimize WASM bundle sizes
- Use browser-specific optimizations
### 3. **Error Handling**
- Test error scenarios thoroughly
- Implement graceful fallbacks
- Monitor error rates in production
- Document known limitations
### 4. **Maintenance**
- Update browser versions regularly
- Review and adjust performance thresholds
- Monitor test execution times
- Keep dependencies up to date
## 🎯 Future Enhancements
### Planned Features
- **Visual Regression Testing**: Automated screenshot comparison
- **Performance Budgets**: Enforce performance thresholds in CI
- **Real Device Testing**: Test on actual mobile devices
- **WASM Profiling**: Detailed performance profiling integration
- **Automated Optimization**: AI-powered performance recommendations
### Integration Opportunities
- **Storybook Integration**: Component story testing
- **Design System Testing**: Visual consistency validation
- **API Testing**: Backend integration testing
- **Load Testing**: High-traffic scenario testing
## 📞 Support
For issues or questions about WASM testing:
1. Check the [troubleshooting section](#-debugging)
2. Review test reports for specific failures
3. Run tests in debug mode for detailed analysis
4. Check browser console for error messages
5. Verify WASM target installation and browser compatibility

**Generated**: $(date)
**WCAG Level**: $WCAG_LEVEL
## Configuration
- **Screen Reader Tests**: $INCLUDE_SCREEN_READER
- **Keyboard Navigation Tests**: $INCLUDE_KEYBOARD_NAV
- **Color Contrast Tests**: $INCLUDE_COLOR_CONTRAST
- **Focus Management Tests**: $INCLUDE_FOCUS_MANAGEMENT
## Summary
- **WCAG Compliance**: $WCAG_LEVEL
- **Test Coverage**: Comprehensive
- **Status**: Completed
## Test Categories
### WCAG $WCAG_LEVEL Compliance
- Testing against Web Content Accessibility Guidelines
- ARIA compliance validation
- Semantic HTML structure verification
### Keyboard Navigation
- Full keyboard accessibility testing
- Logical focus order validation
- Tab navigation support
### Screen Reader Support
- Proper landmark structure
- Live regions for dynamic content
- Skip links for navigation
### Color and Contrast
- Sufficient color contrast ratios
- Color-only information detection
### Focus Management
- Proper focus handling in modals
- Focus restoration after interactions
## Key Recommendations
1. **Ensure all interactive elements have accessible names**
- Use aria-label, aria-labelledby, or visible text content
- Provide meaningful descriptions for screen readers
2. **Provide proper form labels and associations**
- Use for/id attributes to associate labels with inputs
- Include instructions and error messages
3. **Use semantic HTML elements and ARIA landmarks**
- Implement proper heading structure
- Add navigation landmarks
4. **Implement proper focus management for modals**
- Trap focus within modal dialogs
- Restore focus after modal close
5. **Maintain sufficient color contrast ratios**
- Meet WCAG AA standards (4.5:1 for normal text)
- Test with color contrast analyzers
6. **Test with actual screen readers and keyboard navigation**
- Use real assistive technologies
- Validate with actual users
## Running Accessibility Tests
To run accessibility tests manually:
\`\`\`bash
# Run all accessibility tests
make test-e2e-accessibility
# Run specific accessibility test file
pnpm playwright test tests/e2e/accessibility-enhanced.spec.ts
# Run with verbose output
pnpm playwright test tests/e2e/accessibility-enhanced.spec.ts --reporter=list
\`\`\`
