logic2b

The command-line tool for logic2b ui — add beautifully designed, copy-paste components to your project. You own the code.

Usage

Initialize your project (creates components.json and the cn() helper):

npx logic2b@latest init

Add components (registry dependencies are resolved automatically):

npx logic2b@latest add button card dialog

List everything available in the registry:

npx logic2b@latest list

Commands

| Command | Description | | --- | --- | | init | Create components.json and install the cn() helper. | | add <components...> | Add one or more components and their dependencies. | | update [components...] | Pull registry changes into installed components with a 3-way merge — local edits survive; overlapping edits get git-style conflict markers. | | diff [components...] | Show which installed components differ from the registry. | | list | List all components available in the registry. |

add snapshots what it installs under .logic2b/base/ — that snapshot is the base side of update's merge, so keep the directory (committing it is fine). Files installed by older CLI versions have no snapshot; update leaves them untouched and says so.

init and add install the required npm packages automatically, using whichever package manager the project already uses (packageManager field or lockfile — pnpm, npm, yarn or bun). Pass --no-install to just print the install command instead.

Run npx logic2b@latest <command> --help for options.
