Commands

cron create [project-name]

Creates a new cron task management project.

Options:

• -t, --template <template>: Template to use (default: "default")

Example:

npx @alex-programmer/cron create my-scheduler
npx @alex-programmer/cron create my-scheduler --template default

Upgrades an existing project to the latest version while preserving your data and configurations.

Options:

• -f, --force: Force upgrade without confirmation

Example:

npx @alex-programmer/cron upgrade
npx @alex-programmer/cron upgrade --force

What gets preserved during upgrades?

• ✅ SQLite database files (cron_tasks.db, data/cron_tasks.db)
• ✅ Environment files (.env, .env.local, .env.production)
• ✅ Project name and custom package.json configurations
• ✅ Any custom data you've added

What gets updated during upgrades?

• 🔄 Core application files (app/, components/, lib/, types/)
• 🔄 Configuration files (next.config.ts, tsconfig.json, etc.)
• 🔄 Dependencies in package.json
• 🔄 Build scripts and tooling

Project Structure

After creating a project, you'll get:
