# Examples Updated - Scalar Integration Showcase
**Date**: 2025-12-01
**Status**: ✅ COMPLETE
**Related**: SCALAR_INTEGRATION_COMPLETE.md
---
## Executive Summary
Successfully updated existing examples (`default_features.rs` and `all_features.rs`) to showcase the new Scalar integration features, including server configuration, CORS proxy support, and "Try It" functionality.
---
## Changes Made
### 1. `examples/default_features.rs`
**Purpose**: Demonstrate basic Scalar integration with default features.
**New Features Added**:
- Server configuration using `OpenApiGenerator::with_server()`
- Multiple server endpoints (Development, Production)
- Server descriptions for better documentation
- Console output showing configured servers
**Key Code**:
```rust
// Generate OpenAPI spec with server configuration for "Try It" functionality
let spec = OpenApiGenerator::new("API", "1.0.0")
.with_description("Example API with default features")
.with_server("http://localhost:3000", Some("Development"))
.with_server("https://api.example.com", Some("Production"))
.generate(&router);
```
**Output**:
```
Router handlers: 2
Servers configured: 2
- http://localhost:3000
- https://api.example.com
```
---
### 2. `examples/all_features.rs`
**Purpose**: Demonstrate complete Scalar integration with all advanced features.
**New Features Added**:
- Full `ScalarConfig` configuration with all options
- CDN version pinning (`cdn_url`)
- CORS proxy support (`proxy_url`)
- Custom theme (`ScalarTheme::Dark`)
- Custom CSS styling
- Three server configurations (Dev, Production, Staging)
- Enhanced console output showing all features
**Key Code**:
```rust
// Configure Scalar UI with all features
let scalar_config = ScalarConfig::new()
.theme(ScalarTheme::Dark)
.show_sidebar(true)
.cdn_url("https://cdn.jsdelivr.net/npm/@scalar/api-reference@1.25.0")
.proxy_url("https://proxy.scalar.com")
.custom_css(
r#"
body {
font-family: 'Inter', -apple-system, BlinkMacSystemFont, sans-serif;
}
.api-reference {
--scalar-color-accent: #4f46e5;
}
"#,
);
// Generate Scalar HTML documentation
let _scalar_html = allframe_core::router::scalar_html(
&scalar_config,
"AllFrame API",
&openapi_json,
);
```
**Output**:
```
Router handlers: 3
Servers configured: 3
- http://localhost:3000 (Development)
- https://api.example.com (Production)
- https://staging.example.com (Staging)
All features example complete
Scalar features: CDN pinning, CORS proxy, custom theme, 'Try It' enabled
```
---
### 3. `examples/minimal.rs`
**Status**: Unchanged (intentionally)
**Reason**: This example is specifically for baseline binary size measurement with no features enabled. Any changes would invalidate its purpose.
---
### 4. `examples/scalar_docs.rs`
**Status**: Already complete (created earlier)
**Purpose**: Comprehensive standalone demonstration of all Scalar features with full framework integration example.
---
## Progressive Example Demonstration
The examples now provide a clear progression of Scalar integration:
1. **`minimal.rs`**: Baseline (no Scalar)
2. **`default_features.rs`**: Basic server configuration
3. **`all_features.rs`**: Complete Scalar integration with all features
4. **`scalar_docs.rs`**: Production-ready comprehensive example
This structure allows users to:
- Start simple with `default_features.rs`
- See all capabilities with `all_features.rs`
- Get a complete working example with `scalar_docs.rs`
---
## Testing
### Compilation Status
✅ **`minimal.rs`**: Compiles with `--no-default-features`
✅ **`default_features.rs`**: Compiles with default features
✅ **`all_features.rs`**: Compiles with features `"di,openapi,router,cqrs,otel"`
✅ **`scalar_docs.rs`**: Compiles with features `"router,openapi"`
### Runtime Status
✅ **All examples run successfully** and produce expected output
### Test Results
```bash
# default_features.rs
$ cargo run --example default_features
Router handlers: 2
Servers configured: 2
- http://localhost:3000
- https://api.example.com
# all_features.rs
$ cargo run --example all_features --features "di,openapi,router,cqrs,otel"
Router handlers: 3
Servers configured: 3
- http://localhost:3000 (Development)
- https://api.example.com (Production)
- https://staging.example.com (Staging)
All features example complete
Scalar features: CDN pinning, CORS proxy, custom theme, 'Try It' enabled
```
