Command Line Interface

Every command reports a failure as [inca] <command> failed (<code>): … — see Error Codes for what each one means.

inca dev

Watches your app and opens a live-reloading development window, reloading on every change. It stops before building if no host binary can be found. It exits with code 0 when you close the window and non-zero if the host crashes. See Error Codes.

Usage

inca dev

Options

Flag	Description
--experimental-hmr	Reloads only the changed module instead of the whole bundle.

WARNING

--experimental-hmr is experimental. See the HMR guide for what it does differently and its known limitations.

inca build

Bundles your app for production, once, with no window opened. See Building for Production.

Usage

inca build

inca package

Builds your app, then packages it with a prebuilt host binary into a distributable application: a .app on macOS, a plain directory on Linux. See Building for Production.

Usage

inca package

Environment Variables

Variable	Description
INCA_HOST_BIN	Path to a specific host binary, used by dev and package in place of automatic resolution — e.g. on a custom or unpublished build.
INCA_EXPERIMENTAL_HMR	Same as --experimental-hmr, for inca dev. See the HMR guide.
