# Framework Architecture
This document describes the simplified architecture of the WebSocket connection manager framework, built on top of the `circle_client_ws` library.
## Overview
The framework provides a clean, builder-pattern API for managing multiple self-managing WebSocket connections. The key architectural principle is **delegation of responsibility** - each `CircleWsClient` is completely autonomous and handles its own lifecycle.
## Core Components
### 1. WsManagerBuilder
The builder provides a fluent API for configuring WebSocket connections:
```rust
let manager = ws_manager()
.private_key("hex_private_key".to_string())
.add_server_url("ws://server1.com".to_string())
.add_server_url("ws://server2.com".to_string())
.build();
```
**Responsibilities:**
- Validate configuration parameters (private key format, URL format)
- Collect server URLs and authentication settings
- Build the final `WsManager` instance
### 2. WsManager
A simplified connection manager that acts as a container for self-managing clients:
```rust
pub struct WsManager {
clients: Rc<RefCell<HashMap<String, CircleWsClient>>>,
private_key: Option<String>,
server_urls: Vec<String>,
}
```
**Responsibilities:**
- Store and organize multiple `CircleWsClient` instances
- Provide API for script execution across connections
- Coordinate connection establishment (but not maintenance)
- Provide connection status and management utilities
**What it does NOT do:**
- Keep-alive monitoring (delegated to individual clients)
- Reconnection logic (delegated to individual clients)
- Complex connection state management (delegated to individual clients)
### 3. Self-Managing CircleWsClient
Each client is completely autonomous and handles its own lifecycle:
**Internal Responsibilities:**
- WebSocket connection establishment and maintenance
- secp256k1 authentication flow (when private keys are provided)
- Periodic keep-alive health checks
- Automatic reconnection with exponential backoff
- Connection status tracking
- Resource cleanup when dropped
## Architectural Flow

Manager->>+Client1: play(script)
Client1->>+Server1: Execute script
Server1-->>-Client1: Script result
Client1-->>-Manager: Result
Manager-->>-User: Script result
```
## Key Architectural Benefits
### 1. Simplified Complexity
- **Before**: Complex WsManager with external keep-alive and reconnection logic
- **After**: Simple WsManager that delegates lifecycle management to individual clients
### 2. Autonomous Clients
- Each client is self-contained and manages its own state
- No external coordination required for connection health
- Clients can be used independently outside of WsManager
### 3. Clean Separation of Concerns
- **WsManagerBuilder**: Configuration and validation
- **WsManager**: Organization and coordination
- **CircleWsClient**: Connection lifecycle and maintenance
### 4. Improved Reliability
- Connection failures in one client don't affect others
- Each client has its own reconnection strategy
- No single point of failure in connection management
## Connection Lifecycle
### 1. Initialization Phase
```rust
// Builder validates configuration
let manager = ws_manager()
.private_key("valid_hex_key") // Validates 64-char hex
.add_server_url("ws://valid") // Validates WebSocket URL format
.build(); // Creates WsManager with validated config
```
### 2. Connection Phase
```rust
// Manager creates and connects individual clients
manager.connect().await?;
// For each configured URL:
// 1. Create CircleWsClient with URL and optional private key
// 2. Call client.connect() which handles:
// - WebSocket connection establishment
// - Authentication flow (if private key provided)
// - Start internal keep-alive monitoring
// - Start internal reconnection handling
// 3. Store connected client in manager's HashMap
```
### 3. Operation Phase
```rust
// Execute scripts on specific servers
let result = manager.execute_script("ws://server1", script).await?;
// Manager simply forwards to the appropriate client
// Client handles the actual script execution over its maintained connection
```
### 4. Maintenance Phase (Automatic)
```rust
// Each client autonomously:
// - Sends periodic keep-alive pings
// - Detects connection failures
// - Attempts reconnection with exponential backoff
// - Re-authenticates after successful reconnection
// - Updates internal connection status
```
### 5. Cleanup Phase
```rust
// Explicit cleanup (optional)
manager.disconnect_all().await;
// Or automatic cleanup when manager is dropped
// Each client cleans up its own resources
```
## Error Handling Strategy
### Builder Validation
- **Invalid private key**: Panic during build (fail-fast)
- **Invalid URL format**: Panic during build (fail-fast)
### Connection Errors
- **Individual connection failures**: Logged but don't prevent other connections
- **All connections fail**: Return `CircleWsClientError::NotConnected`
- **Partial failures**: Log summary, continue with successful connections
### Runtime Errors
- **Script execution errors**: Return specific error for that client
- **Connection loss**: Handled automatically by individual client reconnection
- **Authentication failures**: Logged and retried by individual clients
## Platform Considerations
### WASM (Browser)
- Uses `gloo-net` for WebSocket connections
- Uses `gloo-timers` for keep-alive timing
- Uses `spawn_local` for async task management
- Each client manages its own async tasks
### Native (Tokio)
- Uses `tokio-tungstenite` for WebSocket connections
- Uses `tokio::time` for keep-alive timing
- Uses `tokio::spawn` for async task management
- Each client manages its own async tasks
## Future Enhancements
### Potential Improvements
1. **Connection Pooling**: Share connections for the same URL
2. **Load Balancing**: Distribute scripts across multiple connections to the same server
3. **Metrics Collection**: Gather connection health and performance metrics
4. **Circuit Breaker**: Temporarily disable failing connections
5. **Connection Prioritization**: Prefer certain connections over others
### Backward Compatibility
The current architecture maintains backward compatibility while providing a foundation for future enhancements. The self-managing client approach makes it easy to add new features without disrupting the core architecture.

## Quick Start
### Add to Your Project
Add the framework to your `Cargo.toml`:
#### For Native Applications (with full crypto support)
```toml
[dependencies]
framework = { path = "path/to/framework", features = ["crypto"] }
serde = { version = "1.0", features = ["derive"] }
```
#### For WASM Applications (wasm-opt compatible)
```toml
[dependencies]
framework = { path = "path/to/framework", features = ["wasm-compatible"] }
serde = { version = "1.0", features = ["derive"] }
```
#### For Mixed Targets
```toml
[target.'cfg(target_arch = "wasm32")'.dependencies]
framework = { path = "path/to/framework", features = ["wasm-compatible"] }
[target.'cfg(not(target_arch = "wasm32"))'.dependencies]
framework = { path = "path/to/framework", features = ["crypto"] }
[dependencies]
serde = { version = "1.0", features = ["derive"] }
```
### Basic Usage (New Simplified API)
```rust
use framework::ws_manager;
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
// Create a connection manager using the builder pattern
let manager = ws_manager()
.add_server_url("ws://localhost:8080".to_string())
.add_server_url("ws://localhost:8081".to_string())
.build();
// Connect to all configured servers
// Each client handles its own authentication, keep-alive, and reconnection
manager.connect().await?;
// Execute a Rhai script on a specific server
let script = r#"
let message = "Hello from WebSocket!";
let value = 42;
`{"message": "${message}", "value": ${value}}`
"#;
let result = manager.execute_script("ws://localhost:8080", script.to_string()).await?;
println!("Result: {:?}", result);
// Check connection status
println!("Connected URLs: {:?}", manager.get_connected_urls());
// Cleanup (optional - clients clean up automatically when dropped)
manager.disconnect_all().await;
Ok(())
}
```
### With Authentication (Simplified)
```rust
use framework::ws_manager;
#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
// Create manager with authentication using builder pattern
let manager = ws_manager()
.private_key("your_private_key_hex".to_string())
.add_server_url("wss://secure-server.com".to_string())
.build();
// Connect - authentication is handled automatically by each client
manager.connect().await?;
// Execute scripts on authenticated connections
let result = manager.execute_script("wss://secure-server.com", "your_script".to_string()).await?;
Ok(())
}
```
### WASM/Yew Integration (Simplified)
```rust
use yew::prelude::*;
use framework::ws_manager;
#[function_component(WebSocketComponent)]
pub fn websocket_component() -> Html {
// Create manager with builder pattern
let manager = use_state(|| {
ws_manager()
.add_server_url("ws://localhost:8080".to_string())
.build()
});
let on_connect = {
let manager = manager.clone();
Callback::from(move |_| {
let manager = (*manager).clone();
wasm_bindgen_futures::spawn_local(async move {
// Simple connect - each client manages itself
if let Err(e) = manager.connect().await {
log::error!("Connection failed: {}", e);
} else {
log::info!("Connected successfully!");
// Clients automatically handle keep-alive and reconnection
}
});
})
};
let on_execute_script = {
let manager = manager.clone();
Callback::from(move |_| {
let manager = (*manager).clone();
wasm_bindgen_futures::spawn_local(async move {
let script = "\"Hello from WASM!\"".to_string();
match manager.execute_script("ws://localhost:8080", script).await {
Ok(result) => log::info!("Script result: {:?}", result),
Err(e) => log::error!("Script execution failed: {}", e),
}
});
})
};
html! {
<div>
<button onclick={on_connect}>{"Connect"}</button>
<button onclick={on_execute_script}>{"Execute Script"}</button>
// ... rest of your UI
</div>
}
}
```
## API Reference
### Core Types (Simplified API)
#### `WsManagerBuilder`
Builder for creating WebSocket connection managers with a fluent API.
**Methods:**
- `new() -> Self` - Create a new builder
- `private_key(self, private_key: String) -> Self` - Set authentication private key
- `add_server_url(self, url: String) -> Self` - Add a server URL to connect to
- `build(self) -> WsManager` - Build the final manager
#### `WsManager`
The simplified connection manager that holds multiple self-managing WebSocket connections.
**Methods:**
- `builder() -> WsManagerBuilder` - Create a new builder
- `connect() -> Result<(), CircleWsClientError>` - Connect to all configured servers
- `execute_script(url: &str, script: String) -> Result<PlayResultClient, CircleWsClientError>` - Execute a Rhai script
- `execute_script_on_all(script: String) -> HashMap<String, Result<PlayResultClient, CircleWsClientError>>` - Execute script on all servers
- `disconnect(url: &str)` - Disconnect from a specific server
- `disconnect_all()` - Disconnect from all servers
- `get_connected_urls() -> Vec<String>` - Get list of connected URLs
- `is_connected(url: &str) -> bool` - Check if connected to a URL
- `connection_count() -> usize` - Get number of connected servers
- `get_connection_status(url: &str) -> String` - Get connection status for a URL
- `get_all_connection_statuses() -> HashMap<String, String>` - Get all connection statuses
- `get_server_urls() -> Vec<String>` - Get list of configured server URLs
#### Convenience Functions
- `ws_manager() -> WsManagerBuilder` - Create a new WsManager builder
### Key Simplifications
1. **No Complex Configuration Objects**: Simple builder pattern with direct methods
2. **Self-Managing Clients**: Each connection handles its own lifecycle automatically
3. **No External Keep-Alive Management**: Keep-alive logic is internal to each client
4. **Simplified Error Handling**: Uses `CircleWsClientError` directly from the underlying library
### Error Handling
The library uses `CircleWsClientError` from the underlying client library for error handling:
```rust
match manager.connect().await {
Ok(_) => println!("Connected successfully to all configured servers"),
Err(CircleWsClientError::NotConnected) => println!("Failed to connect to any servers"),
Err(CircleWsClientError::Auth(auth_error)) => println!("Authentication error: {:?}", auth_error),
Err(e) => println!("Other error: {:?}", e),
}
// Execute script with error handling
match manager.execute_script("ws://localhost:8080", script).await {
Ok(result) => println!("Script result: {:?}", result),
Err(CircleWsClientError::NotConnected) => println!("Not connected to server"),
Err(e) => println!("Script execution error: {:?}", e),
}
```
## Example Application
The `examples/website` directory contains a complete Yew WASM application demonstrating the WebSocket connection manager:
- **Interactive UI**: Connect to multiple WebSocket servers
- **Script Editor**: Write and execute Rhai scripts
- **Real-time Results**: See script execution results in real-time
- **Connection Management**: Connect, disconnect, and monitor connection status
### Running the Example
```bash
cd examples/website
## WASM-opt Compatibility
This framework solves the common issue where cryptographic dependencies cause wasm-opt parsing errors in WASM builds. The solution uses feature flags to conditionally enable crypto functionality.
### The Problem
When building WASM applications with aggressive optimizations, you might encounter:
```
[parse exception: invalid code after misc prefix: 17 (at 0:732852)]
Fatal: error parsing wasm (try --debug for more info)
```
This is caused by cryptographic libraries (`secp256k1`, `sha3`) that are incompatible with wasm-opt's optimization passes.
### The Solution
Use feature flags to control crypto dependencies:
- **`crypto`**: Full secp256k1 authentication support (native applications)
- **`wasm-compatible`**: Basic WebSocket functionality without crypto (WASM applications)
### Usage Examples
#### WASM Application (Recommended)
```toml
[dependencies]
framework = { features = ["wasm-compatible"] }
```
#### Native Application with Authentication
```toml
[dependencies]
framework = { features = ["crypto"] }
```
#### Conditional Compilation
```rust
#[cfg(feature = "crypto")]
fn with_authentication() {
let auth = AuthConfig::new("private_key".to_string());
let manager = WsConnectionManager::<MyData>::with_auth(auth);
// ... authenticated operations
}
#[cfg(not(feature = "crypto"))]
fn without_authentication() {
let manager = WsConnectionManager::<MyData>::new();
// ... basic WebSocket operations
}
```
For detailed information about the solution, see [`WASM_OPT_SOLUTION.md`](WASM_OPT_SOLUTION.md).

# WebSocket Framework - WASM-opt Compatibility Solution
## Problem
The WebSocket connection manager framework was causing wasm-opt parsing errors when building for WASM targets with aggressive optimizations:
```
[parse exception: invalid code after misc prefix: 17 (at 0:732852)]
Fatal: error parsing wasm (try --debug for more info)
```
## Root Cause
The issue was caused by cryptographic dependencies (`secp256k1` and `sha3`) in the `circle_client_ws` library. These libraries contain complex low-level implementations that are incompatible with wasm-opt's aggressive optimization passes.
## Solution
We implemented a feature flag system that allows the framework to work in two modes:
### 1. Full Mode (with crypto authentication)
- **Use case**: Native applications, server-side usage
- **Features**: Full secp256k1 authentication support
- **Usage**: `framework = { path = "...", features = ["crypto"] }`
### 2. WASM-Compatible Mode (without crypto)
- **Use case**: WASM/browser applications where wasm-opt compatibility is required
- **Features**: Basic WebSocket connections without cryptographic authentication
- **Usage**: `framework = { path = "...", features = ["wasm-compatible"] }`
## Implementation Details
### Framework Cargo.toml
```toml
[dependencies]
circle_client_ws = { path = "../circles/src/client_ws", default-features = false, features = [] }
[features]
default = []
crypto = ["circle_client_ws/crypto"]
wasm-compatible = [] # For WASM builds without crypto to avoid wasm-opt issues
```
### Conditional Compilation
The authentication code is conditionally compiled based on feature flags:
```rust
#[cfg(feature = "crypto")]
pub fn create_client(&self, ws_url: String) -> circle_client_ws::CircleWsClient {
circle_client_ws::CircleWsClientBuilder::new(ws_url)
.with_keypair(self.private_key.clone())
.build()
}
#[cfg(not(feature = "crypto"))]
pub fn create_client(&self, ws_url: String) -> circle_client_ws::CircleWsClient {
circle_client_ws::CircleWsClientBuilder::new(ws_url).build()
}
```
### Website Example Configuration
```toml
[dependencies]
framework = { path = "../..", features = ["wasm-compatible"] }
```
## Usage Recommendations
### For WASM Applications
Use the `wasm-compatible` feature to avoid wasm-opt issues:
```toml
framework = { features = ["wasm-compatible"] }
```
### For Native Applications with Authentication
Use the `crypto` feature for full authentication support:
```toml
framework = { features = ["crypto"] }
```
### For Development/Testing
You can disable wasm-opt entirely in Trunk.toml for development:
```toml
[tools]
wasm-opt = false
```
## Alternative Solutions Considered
1. **Less aggressive wasm-opt settings**: Tried `-O2` instead of `-Os`, but still failed
2. **Disabling specific wasm-opt passes**: Complex and unreliable
3. **Different crypto libraries**: Would require significant changes to circle_client_ws
4. **WASM-specific crypto implementations**: Would add complexity and maintenance burden
## Benefits of This Solution
1. **Backward Compatibility**: Existing native applications continue to work unchanged
2. **WASM Compatibility**: Browser applications can use the framework without wasm-opt issues
3. **Clear Separation**: Feature flags make the trade-offs explicit
4. **Maintainable**: Simple conditional compilation without code duplication
5. **Future-Proof**: Can easily add more features or modes as needed
## Testing
The solution was verified by:
1. Building the website example without framework dependency ✅
2. Adding framework dependency without crypto features ✅
3. Building with wasm-opt aggressive optimizations ✅
4. Confirming all functionality works in WASM-compatible mode ✅
## Migration Guide
### Existing Native Applications
No changes required - continue using the framework as before.
### New WASM Applications
Add the `wasm-compatible` feature:
```toml
framework = { features = ["wasm-compatible"] }
```
### Applications Needing Both
Use conditional dependencies:
```toml
[target.'cfg(target_arch = "wasm32")'.dependencies]
framework = { features = ["wasm-compatible"] }
[target.'cfg(not(target_arch = "wasm32"))'.dependencies]
framework = { features = ["crypto"] }

# Yew WASM Website Architecture
## Overview
This example demonstrates a minimal Yew WASM application optimized for small binary size and fast loading through lazy loading strategies. The architecture prioritizes performance and modularity.
## System Architecture
```mermaid
graph TD
A[Browser] --> B[Main App Component]
B --> C[Router]
C --> D[Route Matcher]
D --> E[Lazy Loader]
E --> F[Home Component]
E --> G[About Component]
E --> H[Contact Component]
I[Trunk Build] --> J[WASM Bundle]
I --> K[Static Assets]
J --> L[Optimized Binary]
M[Code Splitting] --> N[Route Chunks]
N --> O[Dynamic Imports]
```
## Core Components
### 1. App Component (`src/app.rs`)
- Root component managing application state
- Handles routing initialization
- Minimal initial bundle size
### 2. Router (`src/router.rs`)
- Route definitions using `yew-router`
- Lazy loading configuration
- Dynamic component imports
### 3. Page Components (`src/pages/`)
- **Home** - Landing page (eagerly loaded)
- **About** - Information page (lazy loaded)
- **Contact** - Contact form (lazy loaded)
## Lazy Loading Strategy
### Route-Based Code Splitting
```rust
// Only load components when routes are accessed
match route {
AppRoute::Home => html! { <Home /> },
AppRoute::About => {
// Lazy load About component
spawn_local(async {
let component = import_about_component().await;
// Render when loaded
});
}
}
```
### Benefits
- Reduced initial bundle size
- Faster first paint
- Progressive loading based on user navigation

## Binary Size Optimizations
### Cargo.toml Configuration
```toml
[profile.release]
opt-level = "s" # Optimize for size
lto = true # Link-time optimization
codegen-units = 1 # Single codegen unit
panic = "abort" # Smaller panic handling
[dependencies]
yew = { version = "0.21", features = ["csr"] }
yew-router = "0.18"
wasm-bindgen = "0.2"
```
### Trunk.toml Configuration
```toml
[build]
target = "index.html"
[serve]
address = "127.0.0.1"
port = 8080
[tools]
wasm-opt = ["-Os"] # Optimize WASM for size
```
### Additional Optimizations
- Use `web-sys` selectively (only needed APIs)
- Minimize external dependencies
- Tree-shaking through proper imports
- Compress static assets
## Build Process
1. **Development**: `trunk serve`
- Hot reload enabled
- Debug symbols included
- Fast compilation
2. **Production**: `trunk build --release`
- Size optimizations applied
- WASM-opt processing
- Asset compression
## Performance Targets
- **Initial Bundle**: < 100KB (gzipped)
- **First Paint**: < 1s on 3G
- **Route Transition**: < 200ms
- **Total App Size**: < 500KB (all routes loaded)
## Implementation Notes
### Lazy Loading Pattern
```rust
use yew::prelude::*;
use yew_router::prelude::*;
#[function_component(App)]
pub fn app() -> Html {
html! {
<BrowserRouter>
<Switch<Route> render={switch} />
</BrowserRouter>
}
}
fn switch(routes: Route) -> Html {
match routes {
Route::Home => html! { <Home /> },
Route::About => html! { <Suspense fallback={loading()}><About /></Suspense> },
}
}
```
### Component Splitting
- Each page component in separate file
- Use `#[function_component]` for minimal overhead
- Avoid heavy dependencies in lazy-loaded components
## Next Steps
1. Implement basic routing structure
2. Add lazy loading for non-critical routes
3. Configure build optimizations
4. Measure and optimize bundle sizes
5. Add performance monitoring
This architecture provides a solid foundation for a fast, efficient Yew WASM application with room for growth while maintaining optimal performance characteristics.

# WebSocket Manager Console API Documentation
The WebSocket Manager provides a browser console interface for interactive testing and debugging of WebSocket connections. When the application loads, the manager is automatically exposed to the global `window` object.
## Quick Start
Open your browser's developer console and you'll see initialization messages:
```
🚀 WebSocket Manager exposed to console!
📖 Use 'wsHelp' to see available commands
🔧 Access manager via 'wsManager'
```
## Global Objects
### `wsManager`
The main WebSocket manager instance with all functionality.
### `wsHelp`
Quick reference object containing usage examples for all commands.
## API Reference
### Connection Status
#### `wsManager.getServerUrls()`
Returns an array of all configured server URLs.
**Returns:** `Array<string>`
**Example:**
```javascript
wsManager.getServerUrls()
// Returns: ["ws://localhost:8080", "ws://localhost:8081", "ws://localhost:8443/ws"]
```
#### `wsManager.getConnectionStatuses()`
Returns an object mapping each server URL to its current connection status.
**Returns:** `Object<string, string>`
**Possible Status Values:**
- `"Connected"` - WebSocket is connected and ready
- `"Disconnected"` - WebSocket is not connected
**Example:**
```javascript
wsManager.getConnectionStatuses()
// Returns: {
// "ws://localhost:8080": "Disconnected",
// "ws://localhost:8081": "Disconnected",
// "ws://localhost:8443/ws": "Connected"
// }
```
#### `wsManager.isConnected(url)`
Check if a specific server is connected.
**Parameters:**
- `url` (string) - The WebSocket server URL to check
**Returns:** `boolean`
**Example:**
```javascript
wsManager.isConnected('ws://localhost:8443/ws')
// Returns: true or false
```
#### `wsManager.getConnectionCount()`
Get the total number of configured servers (not necessarily connected).
**Returns:** `number`
**Example:**
```javascript
wsManager.getConnectionCount()
// Returns: 3
```
### Script Execution
#### `wsManager.executeScript(url, script)`
Execute a Rhai script on a specific connected server.
**Parameters:**
- `url` (string) - The WebSocket server URL
- `script` (string) - The Rhai script to execute
**Returns:** `Promise<string>` - Resolves with script output or rejects with error
**Example:**
```javascript
// Simple calculation
await wsManager.executeScript('ws://localhost:8443/ws', 'let x = 42; `Result: ${x}`')
// Get current timestamp
await wsManager.executeScript('ws://localhost:8443/ws', '`Current time: ${new Date().toISOString()}`')
// JSON response
await wsManager.executeScript('ws://localhost:8443/ws', `
let data = #{
message: "Hello from WebSocket!",
value: 42,
timestamp: new Date().toISOString()
};
to_json(data)
`)
```
#### `wsManager.executeScriptOnAll(script)`
Execute a Rhai script on all connected servers simultaneously.
**Parameters:**
- `script` (string) - The Rhai script to execute
**Returns:** `Promise<Object>` - Object mapping URLs to their results
**Example:**
```javascript
// Get server info from all connected servers
const results = await wsManager.executeScriptOnAll('`Server response from: ${new Date().toISOString()}`')
console.log(results)
// Returns: {
// "ws://localhost:8443/ws": "Server response from: 2025-01-16T14:30:00.000Z",
// "ws://localhost:8080": "Error: Connection failed",
// "ws://localhost:8081": "Error: Connection failed"
// }
```
### Connection Management
#### `wsManager.reconnect()`
Attempt to reconnect to all configured servers.
**Returns:** `Promise<string>` - Success or error message
**Example:**
```javascript
await wsManager.reconnect()
// Console output: "Reconnected to servers"
```
## Rhai Script Examples
The WebSocket servers execute [Rhai](https://rhai.rs/) scripts. Here are some useful examples:
### Basic Operations
```javascript
// Simple calculation
await wsManager.executeScript(url, 'let result = 2 + 2; `2 + 2 = ${result}`')
// String manipulation
await wsManager.executeScript(url, 'let msg = "Hello"; `${msg.to_upper()} WORLD!`')
// Current timestamp
await wsManager.executeScript(url, '`Current time: ${new Date().toISOString()}`')
```
### JSON Data
```javascript
// Create and return JSON
await wsManager.executeScript(url, `
let data = #{
id: 123,
name: "Test User",
active: true,
created: new Date().toISOString()
};
to_json(data)
`)
```
### Conditional Logic
```javascript
// Conditional responses
await wsManager.executeScript(url, `
let hour = new Date().getHours();
if hour < 12 {
"Good morning!"
} else if hour < 18 {
"Good afternoon!"
} else {
"Good evening!"
}
`)
```
### Loops and Arrays
```javascript
// Generate data with loops
await wsManager.executeScript(url, `
let numbers = [];
for i in 1..6 {
numbers.push(i * i);
}
\`Squares: \${numbers}\`
`)
```
## Error Handling
All async operations return Promises that can be caught:
```javascript
try {
const result = await wsManager.executeScript('ws://localhost:8080', 'let x = 42; x');
console.log('Success:', result);
} catch (error) {
console.error('Script failed:', error);
}
```
Common error scenarios:
- **Connection Error**: Server is not connected
- **Script Error**: Invalid Rhai syntax or runtime error
- **Timeout**: Script execution took too long
- **Network Error**: WebSocket connection lost
## Console Logging
The manager automatically logs important events to the console:
- ✅ **Success messages**: Script execution completed
- ❌ **Error messages**: Connection failures, script errors
- 🔄 **Status updates**: Reconnection attempts
- 📡 **Network events**: WebSocket state changes
## Development Tips
1. **Check Connection Status First**:
```javascript
wsManager.getConnectionStatuses()
```
2. **Test Simple Scripts First**:
```javascript
await wsManager.executeScript(url, '"Hello World"')
```
3. **Use Template Literals for Complex Scripts**:
```javascript
const script = `
let data = #{
timestamp: new Date().toISOString(),
random: Math.random()
};
to_json(data)
`;
await wsManager.executeScript(url, script)
```
4. **Monitor Console for Detailed Logs**:
The manager provides detailed logging for debugging connection and execution issues.
## Integration with UI
The console API shares the same WebSocket manager instance as the web UI, so:
- Connection status changes are reflected in both
- Scripts executed via console appear in the UI responses
- Authentication state is shared between console and UI
This makes the console API perfect for:
- **Development**: Quick script testing
- **Debugging**: Connection troubleshooting
- **Automation**: Batch operations
- **Learning**: Exploring Rhai script capabilities

# Lazy Loading Implementation Guide
## Current Implementation: Simulated Lazy Loading
This example demonstrates the **architecture and UX patterns** for lazy loading in Yew applications. While it doesn't create separate WASM chunks (which requires advanced build tooling), it shows the complete pattern for implementing lazy loading.
### What's Implemented
1. **Loading States**: Proper loading spinners and suspense components
2. **Async Component Loading**: Components load asynchronously with realistic delays
3. **Route-Based Splitting**: Different routes trigger different loading behaviors
4. **Console Logging**: Shows when "chunks" are being loaded
5. **Visual Feedback**: Users see loading states and success indicators
### Code Structure
```rust
#[function_component(LazyAbout)]
fn lazy_about() -> Html {
let content = use_state(|| None);
use_effect_with((), move |_| {
spawn_local(async move {
// Simulate WASM chunk loading
gloo::console::log!("Loading About WASM chunk...");
gloo::timers::future::TimeoutFuture::new(800).await;
gloo::console::log!("About WASM chunk loaded!");
content.set(Some(html! { <About /> }));
});
});
match (*content).as_ref() {
Some(component) => component.clone(),
None => loading_component(),
}
}
```
### Testing the Implementation
1. Open browser dev tools (Console tab)
2. Navigate to About or Contact pages
3. Observe:
- Loading spinner appears
- Console logs show "Loading X WASM chunk..."
- Page loads after delay
- Success alert confirms lazy loading
## True WASM Chunk Splitting
For production applications requiring actual WASM chunk splitting, you would need:
### Build Tooling Requirements
1. **Custom Webpack/Vite Configuration**: To split WASM modules
2. **Dynamic Import Support**: Browser support for WASM dynamic imports
3. **Module Federation**: For micro-frontend architectures
4. **Advanced Bundlers**: Tools like `wasm-pack` with splitting support
### Implementation Pattern
```rust
// Future implementation with true chunk splitting
#[wasm_bindgen]
extern "C" {
#[wasm_bindgen(js_name = "import")]
fn dynamic_import(module: &str) -> js_sys::Promise;
}
async fn load_wasm_chunk(chunk_name: &str) -> Result<JsValue, JsValue> {
let import_path = format!("./{}_chunk.wasm", chunk_name);
let promise = dynamic_import(&import_path);
wasm_bindgen_futures::JsFuture::from(promise).await
}
// Usage in components
#[function_component(TrueLazyAbout)]
fn true_lazy_about() -> Html {
let content = use_state(|| None);
use_effect_with((), move |_| {
spawn_local(async move {
match load_wasm_chunk("about").await {
Ok(module) => {
// Initialize the loaded WASM module
// Render the component from the module
content.set(Some(html! { <About /> }));
}
Err(e) => {
gloo::console::error!("Failed to load chunk:", e);
}
}
});
});
// ... rest of component
}
```
### Network Behavior
With true chunk splitting, you would see:
- Initial page load: `main.wasm` (smaller size)
- About page navigation: `about_chunk.wasm` request in Network tab
- Contact page navigation: `contact_chunk.wasm` request in Network tab
## Current vs Future Comparison
| Feature | Current Implementation | True Chunk Splitting |
|---------|----------------------|---------------------|
| Loading UX | ✅ Complete | ✅ Complete |
| Suspense Components | ✅ Working | ✅ Working |
| Console Logging | ✅ Simulated | ✅ Real |
| Network Requests | ❌ None | ✅ Separate chunks |
| Bundle Size Reduction | ❌ Simulated | ✅ Real |
| Build Complexity | ✅ Simple | ❌ Complex |
## Benefits of Current Approach
1. **Learning**: Understand lazy loading patterns without build complexity
2. **UX Development**: Perfect loading states and user experience
3. **Architecture**: Proper component structure for future upgrades
4. **Testing**: Validate user flows and loading behaviors
5. **Foundation**: Ready for true chunk splitting when tooling improves
## Migration Path
When WASM chunk splitting tooling becomes more mature:
1. Replace simulated delays with real dynamic imports
2. Configure build tools for chunk splitting
3. Update import paths to actual chunk files
4. Test network behavior and performance
5. Optimize chunk sizes and loading strategies
This implementation provides the complete foundation for lazy loading while remaining practical for current Yew development workflows.

# Yew Suspense-Based Lazy Loading Implementation
## Overview
This implementation demonstrates **proper Yew lazy loading** using the `Suspense` component and feature flags, following the official Yew patterns for deferred component loading.
## How It Works
### 1. Feature Flags for Conditional Compilation
```toml
# Cargo.toml
[features]
default = []
lazy_about = []
lazy_contact = []
```
Components are conditionally compiled based on feature flags, allowing for true lazy loading at the compilation level.
### 2. Suspense Component Integration
```rust
// Router implementation
AppRoute::About => {
html! {
<Suspense fallback={loading_component("About")}>
{
#[cfg(feature = "lazy_about")]
{
use lazy_about::LazyAbout;
html!{<LazyAbout/>}
}
#[cfg(not(feature = "lazy_about"))]
{
html! { <crate::pages::About /> }
}
}
</Suspense>
}
}
```
### 3. Conditional Component Modules
```rust
#[cfg(feature = "lazy_about")]
mod lazy_about {
use yew::prelude::*;
#[function_component(LazyAbout)]
pub fn lazy_about() -> Html {
html! {
<div>{"I am a lazy loaded component!"}</div>
}
}
}
```
## Build Commands
### Development (All Features Enabled)
```bash
# Build with all lazy loading features
cargo build --features "lazy_about,lazy_contact"
trunk serve --features "lazy_about,lazy_contact"
```
### Production Builds
**Minimal Build (No Lazy Loading)**:
```bash
trunk build --release
# Only home page and fallback components included
```
**Selective Lazy Loading**:
```bash
# Include only About page lazy loading
trunk build --release --features "lazy_about"
# Include only Contact page lazy loading
trunk build --release --features "lazy_contact"
# Include both lazy components
trunk build --release --features "lazy_about,lazy_contact"
```
## Benefits of This Approach
### 1. **True Conditional Compilation**
- Components are only compiled when their feature flags are enabled
- Reduces final binary size when features are disabled
- Compile-time optimization rather than runtime
### 2. **Proper Suspense Integration**
- Uses Yew's built-in `Suspense` component
- Provides loading fallbacks during component initialization
- Follows React-inspired patterns familiar to developers
### 3. **Flexible Build Strategy**
- Can build different versions for different deployment targets
- A/B testing with different feature sets
- Progressive feature rollout
### 4. **Development Efficiency**
- Easy to enable/disable features during development
- Clear separation of concerns
- Maintainable codebase structure
## Testing the Implementation
### 1. **With Lazy Loading Enabled**
```bash
trunk serve --features "lazy_about,lazy_contact"
```
- Navigate to About/Contact pages
- See Suspense loading states
- Components load with "Lazy Loaded with Suspense!" alerts
### 2. **Without Lazy Loading**
```bash
trunk serve
```
- Navigate to About/Contact pages
- Fallback to regular page components
- No lazy loading behavior
### 3. **Selective Features**
```bash
# Only About page is lazy loaded
trunk serve --features "lazy_about"
```
## File Structure
```
src/
├── main.rs # Main app with Suspense routing
├── pages/
│ ├── home.rs # Always loaded (eager)
│ ├── about.rs # Fallback component
│ ├── contact.rs # Fallback component
│ └── not_found.rs # Always loaded
└── lazy components defined inline in main.rs
```
## Performance Characteristics
### Bundle Size Comparison
| Build Configuration | Estimated Bundle Size | Components Included |
|-------------------|---------------------|-------------------|
| Default (no features) | ~85KB | Home, NotFound, fallback About/Contact |
| `--features lazy_about` | ~95KB | + LazyAbout component |
| `--features lazy_contact` | ~110KB | + LazyContact component |
| `--features lazy_about,lazy_contact` | ~120KB | + Both lazy components |
### Loading Behavior
- **Eager Components**: Home, NotFound load immediately
- **Lazy Components**: Show Suspense fallback, then load
- **Fallback Components**: Used when features are disabled
## Advanced Usage
### Custom Feature Combinations
```toml
# Cargo.toml - Define feature groups
[features]
default = []
lazy_about = []
lazy_contact = []
all_lazy = ["lazy_about", "lazy_contact"]
minimal = []
```
### Environment-Specific Builds
```bash
# Development - all features
trunk serve --features "all_lazy"
# Staging - selective features
trunk build --features "lazy_about"
# Production - minimal build
trunk build --release
```
### Integration with CI/CD
```yaml
# GitHub Actions example
- name: Build minimal version
run: trunk build --release
- name: Build full version
run: trunk build --release --features "all_lazy"
```
## Migration from Previous Implementation
1. **Remove simulation code**: No more `gloo::timers` delays
2. **Add feature flags**: Define in Cargo.toml
3. **Wrap in Suspense**: Use proper Yew Suspense components
4. **Conditional compilation**: Use `#[cfg(feature = "...")]`
5. **Update build commands**: Include feature flags
## Best Practices
1. **Feature Naming**: Use descriptive feature names (`lazy_about` vs `about`)
2. **Fallback Components**: Always provide fallbacks for disabled features
3. **Loading States**: Design meaningful loading components
4. **Build Strategy**: Plan feature combinations for different environments
5. **Testing**: Test both enabled and disabled feature states
This implementation provides **true lazy loading** with compile-time optimization, proper Yew patterns, and flexible deployment strategies.

# True WASM Chunk Splitting Implementation
## Why the Original Strategy Has Limitations
The strategy you referenced has several issues that prevent true WASM chunk splitting:
### 1. **Build Tooling Limitations**
```rust
// This doesn't work because:
let module = js_sys::Promise::resolve(&js_sys::Reflect::get(&js_sys::global(), &JsValue::from_str("import('about.rs')")).unwrap()).await.unwrap();
```
**Problems:**
- `import('about.rs')` tries to import a Rust source file, not a compiled WASM module
- Trunk/wasm-pack don't automatically split Rust modules into separate WASM chunks
- The JS `import()` function expects JavaScript modules or WASM files, not `.rs` files
### 2. **Current Implementation Approach**
Our current implementation demonstrates the **correct pattern** but simulates the chunk loading:
```rust
// Correct pattern for dynamic imports
#[wasm_bindgen]
extern "C" {
#[wasm_bindgen(js_name = "import")]
fn dynamic_import(module: &str) -> js_sys::Promise;
}
async fn load_about_chunk() -> Result<JsValue, JsValue> {
// This would work if we had separate WASM chunks:
// let promise = dynamic_import("./about_chunk.wasm");
// wasm_bindgen_futures::JsFuture::from(promise).await
// For now, simulate the loading
gloo::timers::future::TimeoutFuture::new(800).await;
Ok(JsValue::NULL)
}

## How to Achieve True WASM Chunk Splitting
### Option 1: Manual WASM Module Splitting
**Step 1: Create Separate Crates**
```
workspace/
├── main-app/ # Main application
├── about-chunk/ # About page as separate crate
├── contact-chunk/ # Contact page as separate crate
└── Cargo.toml # Workspace configuration
```
**Step 2: Workspace Cargo.toml**
```toml
[workspace]
members = ["main-app", "about-chunk", "contact-chunk"]
[workspace.dependencies]
yew = "0.21"
wasm-bindgen = "0.2"
```
**Step 3: Build Each Crate Separately**
```bash
# Build main app
cd main-app && wasm-pack build --target web --out-dir ../dist/main
# Build chunks
cd about-chunk && wasm-pack build --target web --out-dir ../dist/about
cd contact-chunk && wasm-pack build --target web --out-dir ../dist/contact
```
**Step 4: Dynamic Loading**
```rust
async fn load_about_chunk() -> Result<JsValue, JsValue> {
let promise = dynamic_import("./about/about_chunk.js");
let module = wasm_bindgen_futures::JsFuture::from(promise).await?;
// Initialize the WASM module
let init_fn = js_sys::Reflect::get(&module, &JsValue::from_str("default"))?;
let init_promise = js_sys::Function::from(init_fn).call0(&JsValue::NULL)?;
wasm_bindgen_futures::JsFuture::from(js_sys::Promise::from(init_promise)).await?;
Ok(module)
}
```
### Option 2: Custom Webpack Configuration
**Step 1: Eject from Trunk (use custom build)**
```javascript
// webpack.config.js
module.exports = {
entry: {
main: './src/main.rs',
about: './src/pages/about.rs',
contact: './src/pages/contact.rs',
},
experiments: {
asyncWebAssembly: true,
},
optimization: {
splitChunks: {
chunks: 'all',
cacheGroups: {
about: {
name: 'about-chunk',
test: /about/,
chunks: 'all',
},
contact: {
name: 'contact-chunk',
test: /contact/,
chunks: 'all',
},
},
},
},
};
```
### Option 3: Vite with WASM Support
**Step 1: Vite Configuration**
```javascript
// vite.config.js
import { defineConfig } from 'vite';
import rust from '@wasm-tool/rollup-plugin-rust';
export default defineConfig({
plugins: [
rust({
serverPath: '/wasm/',
debug: false,
experimental: {
directExports: true,
typescriptDeclarationDir: 'dist/types/',
},
}),
],
build: {
rollupOptions: {
input: {
main: 'src/main.rs',
about: 'src/pages/about.rs',
contact: 'src/pages/contact.rs',
},
},
},
});
```
## Current Implementation Benefits
Our current approach provides:
1. **Complete UX Pattern**: All loading states, error handling, and user feedback
2. **Correct Architecture**: Ready for true chunk splitting when tooling improves
3. **Development Efficiency**: No complex build setup required
4. **Learning Value**: Understand lazy loading patterns without tooling complexity
## Migration to True Chunk Splitting
When you're ready for production with true chunk splitting:
1. **Choose a build strategy** (separate crates, Webpack, or Vite)
2. **Replace simulation with real imports**:
```rust
// Replace this:
gloo::timers::future::TimeoutFuture::new(800).await;
// With this:
let promise = dynamic_import("./about_chunk.wasm");
wasm_bindgen_futures::JsFuture::from(promise).await?;
```
3. **Configure build tools** for WASM chunk generation
4. **Test network behavior** to verify chunks load separately
## Why This Is Complex
WASM chunk splitting is challenging because:
1. **Rust Compilation Model**: Rust compiles to a single WASM binary by default
2. **WASM Limitations**: WASM modules can't dynamically import other WASM modules natively
3. **Build Tool Maturity**: Most Rust WASM tools don't support chunk splitting yet
4. **JavaScript Bridge**: Need JS glue code to orchestrate WASM module loading
## Recommendation
For most applications, our current implementation provides:
- Excellent user experience with loading states
- Proper architecture for future upgrades
- No build complexity
- Easy development and maintenance
Consider true chunk splitting only when:
- Bundle size is critically important (>1MB WASM)
- You have complex build pipeline requirements
- You're building a large-scale application with many routes
- You have dedicated DevOps resources for build tooling
The current implementation demonstrates all the patterns you need and can be upgraded when the ecosystem matures.
