Package Exports

@rooks/use-keys

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (@rooks/use-keys) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

@rooks/use-keys

Note: Future updates to this package have moved to the main package rooks. All hooks now reside in a single package which you can install using

npm install rooks

yarn add rooks

Rooks is completely treeshakeable and if you use only 1 of the 50+ hooks in the package, only that hook will be bundled with your code. Your bundle will only contain the hooks that you need. Cheers!

TitleCard

About

A hook which allows to setup callbacks when a combination of keys are pressed at the same time.

An important difference between useKey and useKeys is that useKey checks if EITHER of the keys in the list is pressed, while useKeys checks if ALL of the keys in the list are active.

Installation

npm install --save @rooks/use-keys

Importing the hook

import useKeys from "@rooks/use-keys";

Usage

function Demo() {
  const containerRef = React.useRef(document);
  const inputRef = React.useRef(null);
  const [isEventActive, setIsEventActive] = React.useState(true);
  const [firstCallbackCallCount, setFirstCallbackCallCount] = React.useState(0);
  useKeys(
    ["ControlLeft", "KeyS"],
    () => {
      alert("you presses ctrlLeft + s");
      setFirstCallbackCallCount(firstCallbackCallCount + 1);
    },
    {
      target: containerRef,
      when: isEventActive
    }
  );
  useKeys(
    ["m", "r"],
    event => {
      // event.stopPropagation();
      console.log("here you go m and r");
    },
    {
      when: isEventActive,
      target: inputRef
    }
  );
  return (
    <div data-testid="container">
      <p data-testid="first-callback">
        Callback Run Count:
        {firstCallbackCallCount}
      </p>
      <p>Is events enabled ? ==> {isEventActive ? "Yes" : "No"}</p>
      <p>Press CtrlLeft + s to see update in count</p>
      <button
        onClick={() => {
          setIsEventActive(!isEventActive);
        }}
      >
        Toggle event enabled
      </button>
      <div className="grid-container">
        <input ref={inputRef} className="box1" tabIndex={1} />
      </div>
    </div>
  );
}

render(<Demo />);
