kit build

short: kit b

kit build builds the indicated package directory, or the current working directory if none supplied, e.g.,

kit build foo

or

kit build

kit build builds each process in the package and places the .wasm binaries into the pkg/ directory for installation with kit start-package. It automatically detects what language each process is, and builds it appropriately (from amongst the supported rust, python, and javascript).

Discussion

kit build builds a Kinode package directory. Specifically, it iterates through all directories within the given package directory and looks for src/lib.??, where the ?? is the file extension. Currently, rs, py, and js are supported, corresponding to processes written in rust, python, and javascript, respectively. Note that a package may have more than one process and those processes need not be written in the same language.

After compiling each process, it places the output .wasm binaries within the pkg/ directory at the top-level of the given package directory. Here is an example of what a package directory will look like after using kit build:

rustchat
├── Cargo.lock
├── Cargo.toml
├── metadata.json
├── pkg
│   ├── manifest.json
│   ├── rustchat.wasm
│   ├── scripts.json
│   └── send.wasm
├── rustchat
│   └── ...
└── send
    └── ...

The pkg/ directory is then zipped and can be injected into the node with kit start-package.

kit build also builds the UI if it is found in pkg/ui/. There must exist a ui/package.json file with a scripts object containing the following arguments:

"scripts": {
  "build": "tsc && vite build",
  "copy": "mkdir -p ../pkg/ui && rm -rf ../pkg/ui/* && cp -r dist/* ../pkg/ui/",
  "build:copy": "npm run build && npm run copy",
}

Additional UI dev info can be found here. To both build and start-package in one command, use kit build-start-package.

Arguments

kit build --help
Build a Kinode package

Usage: kit build [OPTIONS] [DIR]

Arguments:
  [DIR]  The package directory to build [default: CWD]

Options:
      --no-ui
          If set, do NOT build the web UI for the process; no-op if passed with UI_ONLY
      --ui-only
          If set, build ONLY the web UI for the process; no-op if passed with NO_UI
  -s, --skip-deps-check
          If set, do not check for dependencies
      --features <FEATURES>
          Pass these comma-delimited feature flags to Rust cargo builds
  -p, --port <NODE_PORT>
          localhost node port; for remote see https://book.kinode.org/hosted-nodes.html#using-kit-with-your-hosted-node [default: 8080]
  -d, --download-from <NODE>
          Download API from this node if not found
  -w, --world <WORLD>
          Fallback WIT world name
  -l, --local-dependency <DEPENDENCY_PACKAGE_PATH>
          Path to local dependency package (can specify multiple times)
  -a, --add-to-api <PATH>
          Path to file to add to api.zip (can specify multiple times)
  -f, --force
          Force a rebuild
  -v, --verbose
          If set, output stdout and stderr
  -h, --help
          Print help

Optional positional arg: DIR

The package directory to build; defaults to the current working directory.

--no-ui

Do not build the web UI for the process. Does nothing if passed with --ui-only.

--ui-only

Build ONLY the UI for a package with a UI. Otherwise, for a package with a UI, both the package and the UI will be built.

--skip-deps-check

short: -s

Don't check for dependencies.

--features

Build the package with the given cargo features.

Features can be used like shown here. Currently the only feature supported system-wide is simulation-mode.

--port

short: -p

Node to pull dependencies from. A package's dependencies can be satisfied by either:

  1. A live node, the one running at the port given here, or
  2. By local dependencies (specified using --local-dependency, below).

--download-from

short: -d

The mirror to download dependencies from (default: package publisher).

--world

short: -w

WIT world to use. Not required for Rust processes; use for py or js.

--local-dependency

short: -l

A path to a package that satisfies a build dependency. Can be specified multiple times.

--add-to-api

short: -a

A path to a file to include in the API published alongside the package. Can be specified multiple times.

--force

short: -f

Don't check if package doesn't need to be rebuilt: just build it.

--verbose

short: -v

Always output stdout and stderr if set.
