This skill provides expertise in using the wasmCloud Shell (wash) CLI tool for developing and managing WebAssembly components and wasmCloud applications.
wash version 2.0.0 or laterwash --versionDo not use cargo component commands (like cargo component build) when working with wasmCloud projects. Always use wash commands instead:
wash build or wash dev for building componentswash build --skip-fetch (since wasmcloud:wash interface isn't published)Use wash dev for local development and build loop. This command:
Example:
wash dev
Use wash wit update when there are mismatched WIT (WebAssembly Interface Types) definitions. This command:
Example:
wash wit update
wash new https://github.com/wasmCloud/wasmCloud.git --name http-hello-world --subfolder templates/http-hello-worldcd my-projectwash build to build the codeA modern wash new Rust HTTP component can follow this structure:
|
|-- .wash/
| -- config.yaml
|-- manifests/
| -- workloaddeployment.yaml
|-- src/
| -- lib.rs
|-- wit/
| -- world.wit
|-- Cargo.toml
|-- Cargo.lock
|-- wkg.lock
