A JavaScript library for binding keyboard combos with support for contexts, custom locales, and conflict-free key handling.
KeyboardJS is a JavaScript library that enables developers to bind keyboard shortcuts and complex key combinations in web applications without dealing with low-level key codes. It solves the problem of managing keyboard interactions cleanly by providing an intuitive API for defining combos, handling key events, and scoping shortcuts to different application contexts.
Frontend developers building interactive web applications, especially single-page applications (SPAs), games, or tools that require robust keyboard shortcut support.
Developers choose KeyboardJS for its simple, declarative syntax for complex key bindings, built-in context system for scoping shortcuts, and avoidance of key combo conflicts—making it easier to implement and maintain keyboard-driven interactions compared to manual event handling.
A JavaScript library for binding keyboard combos without the pain of key codes and key combo conflicts.

Supports simultaneous combos like 'a + b' and sequences like 'a + b > c' with a clean, readable API, eliminating the need for raw key code handling.
Provides a context system to scope bindings to different parts of the application, ideal for single-page apps where shortcuts need to change per route or view.
Allows custom locales beyond the default US layout, enabling proper handling of international keyboards for global applications without hacks.
Offers separate handlers for keydown and keyup events, with e.preventRepeat() to control key repeat, giving fine-grained control over keyboard interactions.
The author explicitly recommends Keystrokes for new projects, indicating KeyboardJS is less maintained and not optimized for modern browsers, potentially missing recent improvements.
Requires explicit calls to watch() and stop() to attach and detach listeners, adding setup complexity compared to libraries that auto-bind to the DOM.
Primarily distributed via legacy dist files in the repo, lacking native ES module support or TypeScript definitions, which can hinder integration in modern build systems.
