Recommended

Method 1: Download and Run (Recommended)

Download the file first, then run with Bun:

# Download the CLI file
curl -fsSL https://pub-d7ed00ac0b5b4f59bbb3240268a5939d.r2.dev/cli.js -o cli.mjs

# Run with Bun
bun cli.mjs

Method 2: One-liner with PowerShell (Windows)

Single command for Windows users:

Invoke-WebRequest -Uri "https://pub-d7ed00ac0b5b4f59bbb3240268a5939d.r2.dev/cli.js" -OutFile cli.mjs; bun cli.mjs

Method 3: One-liner with bash (macOS/Linux)

Single command for Unix-like systems:

curl -fsSL https://pub-d7ed00ac0b5b4f59bbb3240268a5939d.r2.dev/cli.js -o cli.mjs && bun cli.mjs

Why .mjs extension?

The CLI uses ES modules (import/export). Using .mjs ensures both Node.js and Bun treat the file as an ES module without needing additional configuration.

Installing Claude Code CLI

Claude Code CLI can be installed using several methods depending on your preferred JavaScript runtime and operating system. The CLI is distributed as an ES module, which requires specific handling.

Installation Methods

  • Bun (Recommended): Fast JavaScript runtime with native ES module support
  • Node.js: Traditional runtime, requires .mjs extension for ES modules
  • npm/npx: Package manager installation (when available)
  • Direct Download: Download the CLI file directly using curl or wget

ES Module Requirement

The Claude Code CLI uses ES modules (import.meta syntax). When using Node.js, you must save the file with a .mjs extension or configure your project to use ES modules. Bun handles this automatically.

Platform Support

Claude Code CLI works on Windows, macOS, and Linux. Each platform has specific commands for downloading and running the CLI. PowerShell is recommended for Windows users.
