Key Code Constants

keycode-js is a JavaScript package providing a comprehensive set of constants for keyboard events, specifically mapping to KeyboardEvent.keyCode, KeyboardEvent.code, and KeyboardEvent.key properties. The current stable version is 3.1.0. The package maintains a steady release cadence, incorporating new key event codes and values while addressing compatibility and consistency across browser environments. A key differentiator is its provision of constants for all three KeyboardEvent properties, allowing developers to choose the most appropriate and future-proof method for handling keyboard input. It also ships with TypeScript types, enhancing developer experience in TypeScript projects, and offers direct support for Deno environments.
