Why wash

wash is a bundle of command line tools that, together, form a comprehensive CLI for wasmCloud development. Everything from generating new wasmCloud projects, starting local development infrastructure, interacting with OCI compliant registries, and deploying applications is contained within the subcommands of wash. Our goal with wash is to encapsulate our tools into a single binary to make developing WebAssembly with wasmCloud painless and simple.

  build        Build (and sign) a wasmCloud component or capability provider
  dev          Start a developer loop to hot-reload a local wasmCloud component
  inspect      Inspect a capability provider or Wasm component for signing information and interfaces
  par          Create, inspect, and modify capability provider archive files

Run:
  up           Bootstrap a local wasmCloud environment
  down         Tear down a local wasmCloud environment (launched with wash up)
  app          Manage declarative applications and deployments (wadm)
  spy          Spy on all invocations a component sends and receives
  ui           Serve a web UI for wasmCloud

  config       Create configuration for components, capability providers and links

Publish:
  pull         Pull an artifact from an OCI compliant registry
  push         Push an artifact to an OCI compliant registry
  reg          Perform operations on an OCI registry

Configure:
