Perfect for configuration files, templates, small assets, and any files that don't change independently of your component. + +**When to use embedded resources:** +- **Configuration files** that ship with your component +- **Templates and schemas** your component needs at runtime +- **Small static assets** like icons or default data +- **Documentation** that should travel with the component +- **Files under 1MB total** (keeps component size reasonable) + +### Basic Embedding with Rust + +```rust title="src/lib.rs" +// Embed files at compile time +const CONFIG: &str = include_str!("../config/production.json"); +const SCHEMA: &[u8] = include_bytes!("../schemas/api.json"); +const TEMPLATE: &str = include_str!("../templates/response.html"); + +#[cfg(target_arch = "wasm32")] +impl Guest for Component { + fn process_request(input: String) -> String { + // Parse the embedded configuration + let config: Config = serde_json::from_str(CONFIG) + .expect("Invalid embedded config"); + + // Use embedded template + let response = TEMPLATE.replace("{{data}}", &input); + + // Validate against embedded schema + validate_response(&response, SCHEMA); + + response + } +} +``` + +### Build Configuration + +```python title="BUILD.bazel" +load("@rules_wasm_component//rust:defs.bzl", "rust_wasm_component_bindgen") + +rust_wasm_component_bindgen( + name = "web_service_component", + srcs = [ + "src/lib.rs", + "src/config.rs", + ], + wit = ":web_service_interfaces", + # Files are embedded via include_str!/include_bytes! in source + data = [ + "config/production.json", + "schemas/api.json", + "templates/response.html", + ], +) +``` + +### Advanced Embedding with Build-Time Generation + +```python title="BUILD.bazel" +load("@bazel_skylib//rules:write_file.bzl", "write_file") + +# Generate config using Bazel Skylib for cross-platform compatibility +write_file( + name = "production_config", + out = "config/production.json", + content = [ + '{', + ' "environment": "production",', + ' "max_connections": 1000,', + ' "timeout_seconds": 30,', + ' "features": {', + ' "logging": true,', + ' "metrics": true,', + ' "tracing": false', + ' }', + '}', + ], +) + +rust_wasm_component_bindgen( + name = "configured_component", + srcs = ["src/lib.rs"], + wit = ":interfaces", + data = [":production_config"], +) +``` + +**Benefits of embedded resources:** +- βœ… **Single artifact** - No coordination between multiple files +- βœ… **Fast deployment** - Everything loads together +- βœ… **Simple security** - Component signature covers all files +- βœ… **No runtime dependencies** - Files always available + +**Limitations:** +- ❌ **Rebuild required** for file changes +- ❌ **Size bloat** for large files +- ❌ **No dynamic updates** without redeployment + +## 2. OCI Image Layers (Advanced) + +**Use traditional container patterns** when you need large files, dynamic content, or want to separate concerns into different layers.

Examples + +This directory demonstrates **four proven approaches** for packaging WebAssembly components with additional files like configuration, templates, assets, and documentation. + +## 🎯 Quick Start + +```bash +# Build all packaging examples +bazel build //examples/multi_file_packaging:all_examples + +# Test all approaches +bazel test //examples/multi_file_packaging:multi_file_packaging_tests + +# Run specific examples +bazel run //examples/multi_file_packaging:embedded_service_signed +``` + +## πŸ“¦ Packaging Approaches + +### 1. **Embedded Resources** (Recommended) + +- **Files**: Built directly into the component at compile time +- **Access**: Via `include_str!()` and `include_bytes!()` macros +- **Best for**: Configuration files, small templates, schemas under 1MB +- **Security**: Single signature covers everything +- **Example**: `src/embedded_service.rs` + +```rust +// Files embedded at compile time +const CONFIG: &str = include_str!("../config/production.json"); +const TEMPLATE: &str = include_str!("../templates/response.html"); +``` + +### 2. **OCI Image Layers** (Advanced) + +- **Files**: Separate container layers accessed via WASI filesystem +- **Access**: Via `std::fs` APIs with mounted paths +- **Best for**: Large assets, shared files, independent updates +- **Security**: Dual signing (component + OCI manifest) +- **Example**: `src/layered_service.rs` + +```rust +// Read from mounted layer +let config = std::fs::read_to_string("/etc/service/config.json")?; +let template = std::fs::read_to_string("/etc/templates/response.html")?; +``` + +### 3. **Bundle Archives** + +- **Files**: Pre-packaged tar/zip archive with component +- **Access**: Runtime extraction and parsing +- **Best for**: Document collections, related file sets +- **Security**: Single signature for entire bundle +- **Example**: `src/bundled_service.rs` + +```rust +// Extract from embedded bundle +let bundle_data = include_bytes!("../bundle.tar"); +let archive = Archive::new(Cursor::new(bundle_data)); +``` + +### 4. **Sidecar Artifacts** (Complex) + +- **Files**: Separate OCI artifacts with coordinated deployment +- **Access**: Service discovery, shared volumes, or APIs +- **Best for**: Multi-team ownership, independent lifecycles +- **Security**: Multiple signatures requiring coordination +- **Example**: `src/sidecar_service.rs` + +```rust +// Access via sidecar coordination +let config_endpoint = std::env::var("CONFIG_SIDECAR_ENDPOINT")?; +let config = fetch_from_sidecar(&config_endpoint).await?; +``` + +## πŸš€ Building Examples + +### Build Individual Examples + +```bash +# Embedded resources approach +bazel build
