Plan for Adding WebAssembly (WASM) Support to the Web Builder Framework
1. Create WASM Optimizer Module (framework/optimizers/optimize-wasm.nu)
- Build WASM modules using external tools (wasm-pack, wasm-bindgen-cli, emscripten)
- Support for Rust, C/C++, AssemblyScript, and Go compilation
- Optimize WASM binaries with wasm-opt
- Generate JavaScript glue code and TypeScript definitions
- Handle WASM instantiation patterns (sync/async)
2. Extend Configuration System
- Add [wasm] section to page.config.toml template
- Configure WASM source files and build commands
- Specify target environments (web, node, bundler)
- Set optimization levels and features
- Define memory limits and threading options
3. Update Build Pipeline (framework/core/build.nu)
- Add WASM compilation step parallel to JS/CSS processing
- Copy WASM binaries to dist directory
- Generate loader scripts for WASM modules
- Handle WebAssembly.instantiateStreaming fallback
- Support WASM module dependencies
4. Add WASM Development Support (framework/core/dev.nu)
- Watch WASM source files for changes
- Hot-reload WASM modules during development
- Provide WASM debugging information
- Support source maps for WASM
5. Create WASM Tool Integration (framework/core/framework-utils.nu)
- Detect installed WASM toolchains
- Validate WASM build requirements
- Provide fallback mechanisms
- Support multiple WASM languages
6. Add WASM-specific Templates
- Create page templates with WASM integration
- Provide example Rust/C++ WASM projects
- Include WebAssembly loader utilities
- Add performance measurement tools
Configuration Example:
[wasm]
enabled = true
source_dir = "src/wasm"
output_dir = "dist/wasm"
modules = [
{ name = "compute", source = "src/lib.rs", lang = "rust" },
{ name = "graphics", source = "main.c", lang = "c" }
]
[wasm.rust]
toolchain = "wasm-pack" # or "cargo-web"
target = "web" # web, nodejs, bundler
optimization = "O3"
features = ["simd", "threads"]
[wasm.optimization]
use_wasm_opt = true
opt_level = 3 # 0-4
shrink_level = 2 # 0-2
Key Benefits:
- Performance: Native-speed computation for heavy tasks
- Language flexibility: Use Rust, C++, Go, or AssemblyScript
- Progressive enhancement: WASM as optional optimization
- Development experience: Hot-reload and debugging support
- Production ready: Optimization and compression built-in
This approach integrates WASM as a first-class citizen in the framework while maintaining the existing architecture and workflow.
