shadcn/ui CLI

Quickly add pre-built, customizable React components based on Radix UI and Tailwind CSS.

Quick Reference

Command	Purpose
`npx shadcn@latest add <component>`	Add single component
`npx shadcn@latest add btn dialog`	Add multiple components at once
`npx shadcn@latest add -a`	Add ALL components
`npx shadcn@latest add -o <component>`	Overwrite existing component
`npx shadcn@latest view <component>`	Preview component before install
`npx shadcn@latest init`	Initialize project (first-time)

Common Component Groups

Forms: button, input, label, select, checkbox, radio-group, switch, textarea, form

Navigation: dropdown-menu, menubar, navigation-menu, breadcrumb, pagination, command

Data Display: table, data-table, avatar, badge, calendar, carousel, chart

Usage Patterns

Add a single component

npx shadcn@latest add button

Add multiple related components

npx shadcn@latest add form input label select

Skip confirmation prompts

npx shadcn@latest add -y dialog

Overwrite existing component (after shadcn update)

npx shadcn@latest add -o button

Preview before installing

npx shadcn@latest view chart

Custom install path

npx shadcn@latest add button -p src/components/ui

Key Flags

Flag	Short	Description
`--yes`	`-y`	Skip confirmation prompt
`--overwrite`	`-o`	Overwrite existing files
`--all`	`-a`	Install all components
`--path <path>`	`-p`	Custom destination path
`--silent`	`-s`	Suppress output

Project Notes

Components install to src/ui/ in this project (configured in components.json)
Uses @/ path alias for imports
Tailwind CSS + CVA (class-variance-authority) for variants
All components are fully customizable after installation

Troubleshooting

Component already exists: Use -o flag to overwrite

npx shadcn@latest add -o button

Missing dependencies: The CLI auto-installs peer deps, but if issues occur:

npm install @radix-ui/react-<primitive> class-variance-authority

Path issues: Check components.json for configured paths
