Environment Check

Before configuring CLI tools, verify your development environment.

Node.js

Most CLI tools require Node.js 18+.

node --version  # Should show v18.x.x or higher
npm --version

macOS / Linux

Install via nvm (recommended):

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.40.0/install.sh | bash
nvm install --lts

Or download directly from nodejs.org.

Windows

Use LTS version

Restart your terminal after installation for node and npm to be available.

Option 1: Official Installer (Recommended)

Visit https://nodejs.org, download the LTS version Windows Installer (.msi), and install with default settings.

Option 2: Package Manager

# Winget (built into Windows 11/10)
winget install OpenJS.NodeJS.LTS

# Or Chocolatey
choco install nodejs-lts

# Or Scoop
scoop install nodejs-lts

Verify in CMD or PowerShell:

node --version
npm --version

Network

Verify connectivity to Clauddy:

macOS / Linux

curl -I https://clauddy.com  # Should return HTTP 200

Windows (PowerShell)

Invoke-WebRequest -Uri https://clauddy.com -Method Head
# Should return StatusCode 200
