Build Command

The build command compiles your Balius project into a WebAssembly component that can be executed by the Balius runtime.

Usage

cargo balius build

Process

The build command performs the following steps:

1. Executes cargo build with the wasm32-unknown-unknown target
2. Converts the generated .wasm file into a WebAssembly component using wasm-tools

What It Does

This command:

1. Compiles your project to WebAssembly targeting wasm32-unknown-unknown
2. Locates the built .wasm file in your target directory
3. Uses wasm-tools to convert it into a component WebAssembly file with the name format {package_name}-c.wasm

Requirements

• WebAssembly target support in your Rust toolchain (install with rustup target add wasm32-unknown-unknown)
• The wasm-tools command-line utility must be installed in your path

Build Outputs

After running the build command, you'll find:

• A standard WebAssembly file at ./target/wasm32-unknown-unknown/debug/{package_name}.wasm
• A component WebAssembly file at ./{package_name}-c.wasm in your project root directory

Next Steps

After building your project:

1. Test it with cargo balius test
2. Deploy your WebAssembly component to a Balius runtime
