CLI Commands

VitePress provides four main commands: dev, build, preview, and init.

Development Server

Start the dev server with hot module replacement:

# In current directory (dev command is optional)
vitepress

# Or explicitly
vitepress dev

# With project in subdirectory

Options:

Option	Description

vitepress preview docs

Options:

Option	Description
--port <port>	Specify port number
--base <path>	Override base URL

vitepress preview docs --port 4173

Initialize Project

Start the setup wizard:

vitepress init

This creates the basic file structure:

• .vitepress/config.js - Configuration
• index.md - Home page
• Optional example pages

Package.json Scripts

Typical scripts configuration:

{
  "scripts": {
    "docs:dev": "vitepress dev docs",
    "docs:build": "vitepress build docs",
    "docs:preview": "vitepress preview docs"
  }
}

Key Points

• Dev server runs at http://localhost:5173 by default
• Preview server runs at http://localhost:4173
• Production output goes to .vitepress/dist by default
• The docs argument specifies the project root directory
• Use --base to override base path without modifying config
