# 🔧 API Standardization Plan
**Priority**: 🔴 **CRITICAL**
**Timeline**: Week 1-2
**Impact**: Ensures consistent, type-safe APIs across all components
## 🚨 Current API Inconsistencies
### **Type System Issues**
```rust
// Inconsistent prop types across components:
<Button variant="primary"/> // Some components use &str
<Input placeholder="Enter text"/> // Others use MaybeProp<String>
// Inconsistent callback patterns:
on_click=Some(callback) // Some use Option<Callback<T>>
on_change=callback // Others use Callback<T> directly
```
### **Signal Management Inconsistencies**
```rust
// Mixed signal creation patterns:
let (value, set_value) = create_signal(initial); // Deprecated
let (value, set_value) = signal(initial); // Current
```
## 🎯 Standardization Strategy
### **Phase 1: Prop Type Standardization**
#### **1.1 Standardize String Props**
```rust
// Standard pattern for all string props:
#[component]
pub fn ComponentName(
#[prop(into, optional)] placeholder: MaybeProp<String>,
#[prop(into, optional)] label: MaybeProp<String>,
#[prop(into, optional)] class: MaybeProp<String>,
) -> impl IntoView {
// Implementation
}
// Usage with helper macros:
<ComponentName
placeholder=prop_string!("Enter text")
label=prop_string!("Label")
class=prop_string!("custom-class")
/>
```
#### **1.2 Standardize Boolean Props**
```rust
// Standard pattern for all boolean props:
#[component]
pub fn ComponentName(
#[prop(into, optional)] disabled: MaybeProp<bool>,
#[prop(into, optional)] required: MaybeProp<bool>,
#[prop(into, optional)] checked: MaybeProp<bool>,
) -> impl IntoView {
// Implementation
}
// Usage with helper macros:
<ComponentName
disabled=prop_bool!(false)
required=prop_bool!(true)
checked=prop_bool!(false)
/>
```
#### **1.3 Standardize Numeric Props**
```rust
// Standard pattern for all numeric props:
#[component]
pub fn ComponentName(
#[prop(into, optional)] min: MaybeProp<i32>,
#[prop(into, optional)] max: MaybeProp<i32>,
#[prop(into, optional)] step: MaybeProp<f64>,
) -> impl IntoView {
// Implementation
}
// Usage:
<ComponentName
min=prop_number!(0)
max=prop_number!(100)
step=prop_number!(1.0)
/>
```
### **Phase 2: Callback Standardization**
#### **2.1 Standardize Callback Patterns**
```rust
// Standard pattern for all callbacks:
#[component]
pub fn ComponentName(
#[prop(optional)] on_click: Option<Callback<()>>,
#[prop(optional)] on_change: Option<Callback<String>>,
#[prop(optional)] on_submit: Option<Callback<FormData>>,
) -> impl IntoView {
// Implementation
}
// Usage:
<ComponentName
on_click=Some(callback)
on_change=Some(change_callback)
on_submit=Some(submit_callback)
/>
```
#### **2.2 Create Callback Helper Macros**
```rust
// Helper macros for common callback patterns:
#[macro_export]
macro_rules! callback {
($closure:expr) => {
Some(Callback::new($closure))
};
}
// Usage:
<ComponentName
on_click=callback!(|_| println!("Clicked"))
on_change=callback!(|value| println!("Changed: {}", value))
/>
```
### **Phase 3: Signal Management Standardization**
#### **3.1 Standardize Signal Creation**
```rust
// Standard pattern for all signal creation:
use leptos::prelude::*;
// Always use signal() instead of create_signal():
let (value, set_value) = signal(initial_value);
let (is_loading, set_is_loading) = signal(false);
let (items, set_items) = signal(Vec::<String>::new());
```
#### **3.2 Create Signal Helper Functions**
```rust
// Helper functions for common signal patterns:
pub fn create_string_signal(initial: &str) -> (Signal<String>, WriteSignal<String>) {
signal(initial.to_string())
}
pub fn create_bool_signal(initial: bool) -> (Signal<bool>, WriteSignal<bool>) {
signal(initial)
}
pub fn create_vec_signal<T>(initial: Vec<T>) -> (Signal<Vec<T>>, WriteSignal<Vec<T>>)
where
T: Clone + 'static,
{
signal(initial)
}
```

# 🔧 Build System Remediation Plan
**Priority**: 🔴 **CRITICAL - IMMEDIATE**
**Timeline**: Week 1
**Impact**: Blocks all development and production deployment
## 🚨 Critical Issues Identified
### **1. Compilation Failures (68+ errors)**
- **leptos-shadcn-command**: 68 type mismatch errors
- **tailwind-rs-core**: 6 compilation errors (missing types, trait bounds)
- **Multiple packages**: Type conversion issues with `MaybeProp<T>`
### **2. API Inconsistencies**
- `MaybeProp<String>` vs `&str` mismatches
- `Option<Callback<T>>` vs `Callback<T>` inconsistencies
- Deprecated `create_signal` usage (should be `signal()`)
### **3. Dependency Issues**
- Version inconsistencies across Leptos versions
- Unused dependencies causing warnings
- Workspace complexity with 80+ members
## 🎯 Remediation Strategy
### **Phase 1A: Fix Type System Issues (Days 1-2)**
#### **1.1 Standardize MaybeProp Usage**
```rust
// Current problematic pattern:
<CommandInput placeholder="Search..."/> // &str
// Expected:
<CommandInput placeholder="Search...".into()/> // MaybeProp<String>
// Fix: Update all component props to use .into() for string literals
```
#### **1.2 Fix Callback Type Inconsistencies**
```rust
// Current problematic pattern:
on_value_change=Some(callback) // Option<Callback<String>>
// Expected:
on_value_change=callback // Callback<String>
// Fix: Remove Option wrapper where not needed
```
#### **1.3 Update Deprecated APIs**
```rust
// Current deprecated usage:
let (value, set_value) = create_signal(initial_value);
// Updated:
let (value, set_value) = signal(initial_value);
```
### **Phase 1B: Fix Component-Specific Issues (Days 3-4)**
#### **1.4 Command Component Fixes**
- Fix 68 type mismatch errors in `packages/leptos/command/src/tdd_tests.rs`
- Standardize all prop types to use `MaybeProp<T>`
- Fix callback handling patterns
#### **1.5 Tailwind Core Fixes**
- Fix missing type definitions (`ReactiveThemeManager`, `ReactiveColor`)
- Resolve trait bound issues
- Fix example compilation errors
### **Phase 1C: Dependency Cleanup (Day 5)**
#### **1.6 Version Standardization**
```toml
# Standardize on single Leptos version across all packages
leptos = "0.8.8" # Use latest stable
leptos_router = "0.8.8"
```
#### **1.7 Remove Unused Dependencies**
- Clean up unused imports and dependencies
- Remove dead code causing warnings
- Optimize workspace member list

# 🔧 Bundle Analysis Implementation Design
**Component**: `leptos-shadcn-performance-audit`
**Priority**: 🟡 **HIGH**
**Issues**: 3 todo! implementations in bundle analysis
**Timeline**: 3-4 days
## 🚨 Stub Code Issues
### **Missing Implementations**
```rust
// File: performance-audit/src/bundle_analysis.rs
// Line 179:
todo!("Implement component bundle analysis")
// Line 185:
todo!("Implement single component analysis")
// Line 191:
todo!("Implement bundle size extraction")
```
## 🎯 Implementation Strategy
### **Phase 1: Component Bundle Analysis**
#### **1.1 Implement Bundle Analysis Core**
```rust
// File: performance-audit/src/bundle_analysis.rs
use std::path::Path;
use std::fs;
use serde::{Deserialize, Serialize};
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct ComponentBundleInfo {
pub component_name: String,
pub bundle_size: u64,
pub dependencies: Vec<String>,
pub exports: Vec<String>,
pub file_path: String,
}
impl BundleAnalyzer {
pub fn analyze_component_bundles(&self, components_path: &Path) -> Result<Vec<ComponentBundleInfo>, BundleAnalysisError> {
let mut bundle_info = Vec::new();
// Scan for component directories
let entries = fs::read_dir(components_path)?;
for entry in entries {
let entry = entry?;
let path = entry.path();
if path.is_dir() {
if let Some(component_name) = path.file_name().and_then(|n| n.to_str()) {
if component_name.starts_with("leptos-shadcn-") {
let info = self.analyze_single_component(&path, component_name)?;
bundle_info.push(info);
}
}
}
}
Ok(bundle_info)
}
}
```
#### **1.2 Component Analysis Logic**
```rust
impl BundleAnalyzer {
fn analyze_single_component(&self, component_path: &Path, component_name: &str) -> Result<ComponentBundleInfo, BundleAnalysisError> {
let mut bundle_size = 0;
let mut dependencies = Vec::new();
let mut exports = Vec::new();
// Analyze Cargo.toml for dependencies
let cargo_toml = component_path.join("Cargo.toml");
if cargo_toml.exists() {
let cargo_content = fs::read_to_string(&cargo_toml)?;
dependencies = self.extract_dependencies(&cargo_content);
}
// Analyze source files for exports
let src_path = component_path.join("src");
if src_path.exists() {
exports = self.extract_exports(&src_path)?;
bundle_size = self.calculate_bundle_size(&src_path)?;
}
Ok(ComponentBundleInfo {
component_name: component_name.to_string(),
bundle_size,
dependencies,
exports,
file_path: component_path.to_string_lossy().to_string(),
})
}
}
```
### **Phase 2: Single Component Analysis**
#### **2.1 Detailed Component Analysis**
```rust
impl BundleAnalyzer {
pub fn analyze_single_component_detailed(&self, component_path: &Path) -> Result<DetailedComponentAnalysis, BundleAnalysisError> {
let mut analysis = DetailedComponentAnalysis::new();
// Analyze source code structure
analysis.source_files = self.analyze_source_files(component_path)?;
analysis.dependencies = self.analyze_dependencies(component_path)?;
analysis.exports = self.analyze_exports(component_path)?;
analysis.imports = self.analyze_imports(component_path)?;
// Calculate metrics
analysis.total_lines = self.count_total_lines(&analysis.source_files);
analysis.complexity_score = self.calculate_complexity(&analysis.source_files);
analysis.bundle_size_estimate = self.estimate_bundle_size(&analysis);
Ok(analysis)
}
}
```
#### **2.2 Source File Analysis**
```rust
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct SourceFileAnalysis {
pub file_path: String,
pub lines_of_code: usize,
pub functions: Vec<String>,
pub structs: Vec<String>,
pub enums: Vec<String>,
pub imports: Vec<String>,
pub exports: Vec<String>,
}
impl BundleAnalyzer {
fn analyze_source_files(&self, component_path: &Path) -> Result<Vec<SourceFileAnalysis>, BundleAnalysisError> {
let mut analyses = Vec::new();
let src_path = component_path.join("src");
if src_path.exists() {
self.analyze_directory_recursive(&src_path, &mut analyses)?;
}
Ok(analyses)
}
fn analyze_directory_recursive(&self, dir: &Path, analyses: &mut Vec<SourceFileAnalysis>) -> Result<(), BundleAnalysisError> {
let entries = fs::read_dir(dir)?;
for entry in entries {
let entry = entry?;
let path = entry.path();
if path.is_file() && path.extension().and_then(|s| s.to_str()) == Some("rs") {
let analysis = self.analyze_rust_file(&path)?;
analyses.push(analysis);
} else if path.is_dir() {
self.analyze_directory_recursive(&path, analyses)?;
}
}
Ok(())
}
}
```
### **Phase 3: Bundle Size Extraction**
#### **3.1 Bundle Size Calculation**
```rust
impl BundleAnalyzer {
pub fn extract_bundle_sizes(&self, components_path: &Path) -> Result<BundleSizeReport, BundleAnalysisError> {
let mut report = BundleSizeReport::new();
// Analyze each component
let components = self.analyze_component_bundles(components_path)?;
for component in components {
let size_info = BundleSizeInfo {
component_name: component.component_name.clone(),
estimated_size: component.bundle_size,
dependencies_size: self.calculate_dependencies_size(&component.dependencies)?,
total_size: component.bundle_size + self.calculate_dependencies_size(&component.dependencies)?,
optimization_potential: self.assess_optimization_potential(&component),
};
report.components.push(size_info);
}
// Calculate totals
report.total_bundle_size = report.components.iter().map(|c| c.total_size).sum();
report.average_component_size = report.total_bundle_size / report.components.len() as u64;
report.largest_component = report.components.iter().max_by_key(|c| c.total_size).cloned();
Ok(report)
}
}
```
#### **3.2 Size Estimation Logic**
```rust
impl BundleAnalyzer {
fn calculate_bundle_size(&self, src_path: &Path) -> Result<u64, BundleAnalysisError> {
let mut total_size = 0;
// Count lines of code as proxy for bundle size
let source_files = self.get_rust_files(src_path)?;
for file in source_files {
let content = fs::read_to_string(&file)?;
let lines = content.lines().count();
// Rough estimation: 1 line ≈ 50 bytes in compiled WASM
total_size += lines as u64 * 50;
}
Ok(total_size)
}
fn calculate_dependencies_size(&self, dependencies: &[String]) -> Result<u64, BundleAnalysisError> {
// Estimate dependency sizes based on known packages
let mut total_size = 0;
for dep in dependencies {
let estimated_size = match dep.as_str() {
"leptos" => 50000, // ~50KB
"leptos_router" => 20000, // ~20KB
"serde" => 15000, // ~15KB
"web-sys" => 10000, // ~10KB
_ => 5000, // Default estimate
};
total_size += estimated_size;
}
Ok(total_size)
}
}
```

# 🔧 Command Component Fix Design
**Component**: `leptos-shadcn-command`
**Priority**: 🔴 **CRITICAL**
**Issues**: 68 compilation errors, type mismatches
**Timeline**: 2-3 days
## 🚨 Critical Issues
### **Type Mismatch Errors (68 total)**
```rust
// Error pattern 1: String literal vs MaybeProp<String>
<CommandInput placeholder="Search..."/> // ❌ &str
// Expected:
<CommandInput placeholder="Search...".into()/> // ✅ MaybeProp<String>
// Error pattern 2: Boolean literal vs MaybeProp<bool>
<CommandItem disabled=true>"Disabled Item"</CommandItem> // ❌ bool
// Expected:
<CommandItem disabled=true.into()>"Disabled Item"</CommandItem> // ✅ MaybeProp<bool>
// Error pattern 3: Option<Callback> vs Callback
on_value_change=Some(callback) // ❌ Option<Callback<String>>
// Expected:
on_value_change=callback // ✅ Callback<String>
```
## 🎯 Fix Strategy
### **Phase 1: Prop Type Standardization**
#### **1.1 String Props Fix**
```rust
// Create helper macro for string literals
macro_rules! prop_string {
($value:literal) => {
$value.into()
};
}
// Usage in tests:
<CommandInput placeholder=prop_string!("Search...")/>
<CommandGroup heading=prop_string!("Suggestions")>
```
#### **1.2 Boolean Props Fix**
```rust
// Create helper macro for boolean literals
macro_rules! prop_bool {
($value:literal) => {
$value.into()
};
}
// Usage in tests:
<CommandItem disabled=prop_bool!(true)>
```
#### **1.3 Callback Props Fix**
```rust
// Remove Option wrapper where not needed
// Before:
on_value_change=Some(callback)
// After:
on_value_change=callback
```
### **Phase 2: Test Case Updates**
#### **2.1 Update All Test Cases**
```rust
// File: packages/leptos/command/src/tdd_tests.rs
// Update all 68 error locations with proper type conversions
// Example fix:
#[test]
fn test_command_basic_functionality() {
view! {
<Command on_value_change=callback>
<CommandInput placeholder=prop_string!("Search...")/>
<CommandGroup heading=prop_string!("Suggestions")>
<CommandItem disabled=prop_bool!(false)>"Item 1"</CommandItem>
</CommandGroup>
</Command>
}
}
```
#### **2.2 Create Type-Safe Test Helpers**
```rust
// Add to test module:
mod test_helpers {
use leptos::prelude::*;
pub fn string_prop(s: &str) -> MaybeProp<String> {
s.into()
}
pub fn bool_prop(b: bool) -> MaybeProp<bool> {
b.into()
}
pub fn callback_prop<T, F>(f: F) -> Callback<T>
where
F: Fn(T) + 'static,
{
Callback::new(f)
}
}
```
### **Phase 3: Component API Review**
#### **3.1 Verify Component Definitions**
```rust
// Check component prop definitions in:
// packages/leptos/command/src/default.rs
// packages/leptos/command/src/new_york.rs
// Ensure all props use MaybeProp<T> consistently:
#[component]
pub fn CommandInput(
#[prop(into, optional)] placeholder: MaybeProp<String>,
#[prop(into, optional)] disabled: MaybeProp<bool>,
// ... other props
) -> impl IntoView {
// Implementation
}
```
#### **3.2 Update Component Documentation**
```rust
// Add prop type documentation:
/// Command input component with type-safe props
///
/// # Props
/// - `placeholder`: MaybeProp<String> - Input placeholder text
/// - `disabled`: MaybeProp<bool> - Whether input is disabled
/// - `on_value_change`: Callback<String> - Value change callback
```
## 📋 Implementation Steps
### **Step 1: Create Helper Macros (Day 1)**
```rust
// Add to packages/leptos/command/src/lib.rs
#[macro_export]
macro_rules! prop_string {
($value:literal) => {
$value.into()
};
}
#[macro_export]
macro_rules! prop_bool {
($value:literal) => {
$value.into()
};
}
```
### **Step 2: Fix Test Cases (Day 2)**
```bash
# Fix all 68 errors in tdd_tests.rs
# Use find/replace with regex patterns:
# Find: placeholder="([^"]*)"
# Replace: placeholder=prop_string!("$1")
# Find: disabled=([^>]*)
# Replace: disabled=prop_bool!($1)
```
### **Step 3: Verify and Test (Day 3)**
```bash
# Test compilation:
cargo check --package leptos-shadcn-command
# Run tests:
cargo test --package leptos-shadcn-command
# Verify functionality:
cargo test --package leptos-shadcn-command --lib
```
## 🧪 Testing Strategy
### **Compilation Tests**
```bash
# Verify no compilation errors:
cargo check --package leptos-shadcn-command --lib
cargo check --package leptos-shadcn-command --tests
```
### **Functionality Tests**
```bash
# Run all command component tests:
cargo test --package leptos-shadcn-command --lib
cargo test --package leptos-shadcn-command --test tdd_tests
```
### **Integration Tests**
```bash
# Test command component in example app:
cargo run --example leptos-demo
```
## 📊 Success Criteria
-**Zero compilation errors** in command component
-**All 68 type mismatch errors resolved**
-**All tests passing** for command component
-**Type-safe prop usage** throughout
-**Consistent API patterns** with other components
## 🚨 Risk Mitigation
### **Backup Strategy**
```bash
# Create backup branch:
git checkout -b fix/command-component-types
git add -A && git commit -m "Backup before command component fixes"
```
### **Incremental Testing**
- Fix 10-15 errors at a time
- Test compilation after each batch
- Commit working fixes immediately
### **Reference Implementation**
- Use button component as reference for correct patterns
- Compare prop definitions with working components
- Maintain consistency with established patterns

// File: packages/tailwind-rs-core/examples/leptos_integration.rs
```
## 🎯 Fix Strategy
### **Phase 1: Implement Missing Types**
#### **1.1 Create ReactiveThemeManager**
```rust
// File: packages/tailwind-rs-core/src/leptos_integration.rs
use leptos::prelude::*;
pub struct ReactiveThemeManager {
current_theme: Signal<String>,
available_themes: Vec<String>,
}
impl ReactiveThemeManager {
pub fn new() -> Self {
Self {
current_theme: signal("default".to_string()),
available_themes: vec!["default".to_string(), "dark".to_string()],
}
}
pub fn get_current_theme(&self) -> Signal<String> {
self.current_theme
}
pub fn set_theme(&self, theme: String) {
self.current_theme.set(theme);
}
pub fn get_available_themes(&self) -> &Vec<String> {
&self.available_themes
}
}
```
#### **1.2 Create ReactiveColor**
```rust
// File: packages/tailwind-rs-core/src/leptos_integration.rs
pub struct ReactiveColor {
current_color: Signal<Color>,
color_palette: Vec<Color>,
}
impl ReactiveColor {
pub fn new(initial_color: Color) -> Self {
Self {
current_color: signal(initial_color),
color_palette: vec![
Color::Red, Color::Blue, Color::Green,
Color::Yellow, Color::Purple, Color::Orange
],
}
}
pub fn get_current_color(&self) -> Signal<Color> {
self.current_color
}
pub fn set_color(&self, color: Color) {
self.current_color.set(color);
}
pub fn get_palette(&self) -> &Vec<Color> {
&self.color_palette
}
}
```
### **Phase 2: Fix Trait Bound Issues**
#### **2.1 Fix View Type Conversions**
```rust
// Fix AnyView conversion issues:
// Before:
{children.map(|c| c()).unwrap_or_else(|| "Click me".into())} // ❌
// After:
{children.map(|c| c()).unwrap_or_else(|| view! { "Click me" })} // ✅
// Or use Fragment:
{children.map(|c| c()).unwrap_or_else(|| Fragment::new(vec!["Click me".into()]))} // ✅
```
#### **2.2 Create View Helper Functions**
```rust
// Add helper functions for common view patterns:
pub fn text_view(text: &str) -> impl IntoView {
view! { {text} }
}
pub fn button_text() -> impl IntoView {
view! { "Click me" }
}
pub fn card_content() -> impl IntoView {
view! { "Card content" }
}
```
### **Phase 3: Fix Example Compilation**
#### **3.1 Add Main Function to Example**
```rust
// File: packages/tailwind-rs-core/examples/leptos_integration.rs
// Add at the end of the file:
fn main() {
// Example usage of the integration components
leptos::mount_to_body(|| {
view! {
<div>
<h1>"Tailwind-RS-Core Integration Example"</h1>
<ReactiveButton />
<ReactiveCard />
<ReactiveThemeExample />
<ReactiveColorExample />
</div>
}
})
}
```
#### **3.2 Fix Deprecated API Usage**
```rust
// Replace deprecated create_signal with signal:
// Before:
let (email, set_email) = create_signal(String::new()); // ❌
let (is_valid, set_is_valid) = create_signal(false); // ❌
// After:
let (email, set_email) = signal(String::new()); // ✅
let (is_valid, set_is_valid) = signal(false); // ✅
// Replace deprecated create_memo with Memo::new:
// Before:
let input_classes = create_memo(move |_| { ... }); // ❌
// After:
let input_classes = Memo::new(move |_| { ... }); // ✅
```
## 📋 Implementation Steps
### **Step 1: Add Missing Types (Day 1)**
```rust
// 1. Add ReactiveThemeManager implementation
// 2. Add ReactiveColor implementation
// 3. Export types in lib.rs
// 4. Test compilation
```
### **Step 2: Fix Trait Bounds (Day 2)**
```rust
// 1. Fix all AnyView conversion issues
// 2. Add view helper functions
// 3. Update example components
// 4. Test view rendering
```
### **Step 3: Fix Examples (Day 3)**
```rust
// 1. Add main function to leptos_integration example
// 2. Fix deprecated API usage
// 3. Test example compilation
// 4. Verify example functionality
```
## 🧪 Testing Strategy
### **Compilation Tests**
```bash
# Test core library:
cargo check --package tailwind-rs-core
# Test examples:
cargo check --package tailwind-rs-core --examples

self.report_metrics(&metrics)?;
// Sleep for monitoring interval
std::thread::sleep(self.monitoring_interval);
}
}

Ok(metrics)
}
}
