CLI Setup

The LaunchMyStore CLI (lms) helps you develop, test, and deploy apps from the command line.
The CLI is coming soon! This documentation previews the planned features.

​
Installation

npm install -g @launchmystore/cli
Verify installation: 
lms --version

​
Authentication

Log in with your developer account: 
lms auth login
This opens your browser to authenticate. Once complete, your credentials are stored securely. Check your current session: 
lms auth whoami

​
Creating an App

Create a new app project: 
lms app create
Follow the interactive prompts to:
  1. Choose a name and handle
  2. Select a template (Node.js, React, Remix, Extension-only)
  3. Configure OAuth scopes
  4. Choose extension types
The CLI will:
  • Download the template
  • Register your app with LaunchMyStore
  • Create .lmsrc.json config file
  • Generate .env with credentials

​
Development Server

Start the development server with a secure tunnel: 
lms app dev
This:
  • Starts your local dev server
  • Creates a Cloudflare tunnel for webhook testing
  • Updates your app’s redirect URLs automatically
  • Watches for extension changes
