clipboardy is a cross-platform Node.js library that provides a simple, unified API for accessing the system clipboard (copy/paste). It supports macOS, Windows, Linux (including Wayland), WSL, Android (Termux), and modern browsers. The library offers both asynchronous and synchronous methods for reading and writing text, and additionally supports image operations on macOS via the `clipboard-image` package. The implementation automatically detects the platform at runtime and delegates to the appropriate system commands (e.g., `pbcopy`/`pbpaste` on macOS, `Set-Clipboard`/`Get-Clipboard` PowerShell cmdlets on Windows, `xsel` on Linux with a bundled fallback, `wl-copy`/`wl-paste` on Wayland). It carefully handles edge cases such as the Wayland clipboard daemon's background process hang (by redirecting stderr to a temporary file) and gracefully falls back to X11 tools when Wayland is unavailable. The code is well-tested, with a comprehensive test suite covering various content types, error handling, and platform-specific behaviors. The library is a mature, widely-used piece of infrastructure (nearly 2000 stars) that exemplifies clean, reliable Node.js package design.
