Options

npm create implement-app@latest [directory] -- [options]

directory is where the app goes, relative to the current directory. Leave it off and the CLI asks, defaulting to implement-app.

The -- is npm's; pnpm, yarn, and bun pass flags through without it.

Project

Flag	What it does
--name <name>	The name written into package.json. Defaults to the directory name, normalized into something npm accepts.
-t, --template	kit or csr. See Templates.
--tailwind	Set up Tailwind. --no-tailwind opts out.
--primitives	Add @implementjs/primitives. --no-primitives opts out.
--ui	Add @implementjs/ui. Turns on --tailwind and --primitives; --no-ui opts out.
--icons	Add @implementjs/lucide. --no-icons opts out.
--forms	Add @implementjs/formish and valibot. --no-forms opts out.
--mode-watcher	Add @implementjs/mode-watcher. --no-mode-watcher opts out.
--overwrite	Scaffold into the directory even if it already has files in it.

Without --overwrite, a non-empty directory stops the run — interactively it asks first.

After scaffolding

Flag	What it does
--install	Install dependencies. For the kit template this also runs sync, so .implement/ exists and the app typechecks immediately. With --ui it also runs jsrepo add button, the one component the starter page renders.
--git	Run git init in the new directory.
--package-manager	npm, pnpm, yarn, bun, or deno. Detected from the environment otherwise.

The package manager is picked up from how you invoked the CLI, so pnpm create implement-app installs with pnpm without being told.

Running unattended

Flag	What it does
-y, --yes	Skip every prompt, using defaults for anything a flag didn't answer.
--cwd <path>	Resolve relative paths against this directory instead of the current one.
--verbose	Log each step instead of collapsing it into a spinner.
-V, --version	Print the CLI version.

Prompts are also skipped whenever there is no terminal attached, so agents and CI drive the CLI entirely with flags — --yes is only needed when a terminal is attached.

The defaults a skipped prompt falls back to: the kit template, the Tailwind addon, and no addons beyond it.
