Installation

You can install the package using npm:

npm install react-mkx-toolkit

Or using yarn:

yarn add react-mkx-toolkit

useKeyboard

The useKeyboard hook is a custom React hook designed to simplify the handling of keyboard events within your React applications. With this hook, you can easily listen for specific keyboard inputs and execute callback functions in response to those inputs.

Usage

import { useKeyboard } from "react-mkx-toolkit";

const MyComponent = () => {
  const handleKeyPress = () => {
    console.log("The Enter key was pressed!");
  };

  useKeyboard("Enter", handleKeyPress);
  return <>MyComponent</>;
};
export default MyComponent;

useRandomArray

The useRandomArray hook is useful for scenarios where you need to generate a sequence of numbers within a specified range, such as creating test data, generating random values, or iterating through a range of numerical values.

Usage

import { useRandomArray } from "react-mkx-toolkit";

const MyComponent = () => {
  const arr = useRandomArray(0, 10);
  //Output : [ 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 ]
  return <>MyComponent</>;
};
export default MyComponent;

useCurrentLocation

The useCurrentLocation hook to retrieve the current geographic location of the user. This hook is useful for scenarios where you need to access the user's current location for various purposes such as location-based services, mapping applications, or any feature requiring the user's geographical coordinates.

Usage

import { useCurrentLocation } from "react-mkx-toolkit";

const MyComponent = () => {
  const { display_name, address, latitude, longitude } = useCurrentLocation();

  return (
    <div>
      <p>
        <span>Display Name : </span>
        <span>{display_name}</span>
      </p>
      <p>
        <span>Latitude : </span>
        <span>{latitude}</span>
      </p>
      <p>
        <span>Longitude : </span>
        <span>{longitude}</span>
      </p>
      <p>
        <span>Address : </span>
        <span>{JSON.stringify(address)}</span>
      </p>
    </div>
  );
};
export default MyComponent;

useScroll

The useScroll hook is a custom React hook designed to provide a set of utilities for scrolling within a web application. Its main purpose is to encapsulate common scrolling functionality, making it easier to manage and reuse scrolling behavior across different components.

Usage

import React from "react";
import { useScroll } from "react-mkx-toolkit";

function ScrollComponent() {
  const { scrollToTop, scrollToBottom, scrollById } = useScroll();

  const handleScrollToTop = () => {
    scrollToTop();
  };

  const handleScrollToBottom = () => {
    scrollToBottom();
  };

  const handleScrollById = () => {
    scrollById("myElementId", {
      behavior: "smooth",
      block: "start",
      inline: "nearest",
    });
  };

  return (
    <div>
      <button onClick={handleScrollToTop}>Scroll to Top</button>
      <button onClick={handleScrollToBottom}>Scroll to Bottom</button>
      <button onClick={handleScrollById}>Scroll to Element with ID</button>
      <div id="myElementId">Element to scroll to</div>
    </div>
  );
}

export default ScrollComponent;

useNotification

The useNotification hook simplifies the process of working with browser notifications in React applications. It provides a clean and intuitive interface for requesting permission and displaying notifications.

Usage

import { useNotification } from "react-mkx-toolkit";

const MyComponent = () => {
  const { requestPermission, showNotification, notificationPermission } =
    useNotification();

  const handleClick = () => {
    showNotification("Hello!", {
      body: "This is a notification from your web app.",
      icon: "path/to/your/icon.png",
    });
  };

  return (
    <div>
      <button onClick={requestPermission}>Request Permission</button>
      <button
        onClick={handleClick}
        disabled={notificationPermission !== "granted"}
      >
        Show Notification
      </button>
    </div>
  );
};

export default MyComponent;

Note

Call the requestPermission Function to request permission from the user before showing notifications.

Returns

• requestPermission: A function to request permission for displaying notifications.
• showNotification: A function to display notifications with the given title and options.
• notificationPermission: The current notification permission state (granted, denied, or default).

useOnlineStatus

The useOnlineStatus hook helps you track the browser’s online/offline status. It utilizes the navigator.onLine property and listens to the online and offline events to update the status in real time.

Usage

import React from "react";
import { useOnlineStatus } from "react-mkx-toolkit";

const MyComponent = () => {
  const isOnline = useOnlineStatus();

  return (
    <div>
      <h1>Network Status</h1>
      <p>{isOnline ? "🟢 Online" : "🔴 Offline"}</p>
    </div>
  );
};

export default MyComponent;

Features

• Automatically updates when the browser goes online or offline.
• Compatible with modern browsers and React versions.
• Useful for network-aware components or offline-first applications.

useWindowSize

The useWindowSize hook allows you to track the current dimensions of the browser window. It listens to the resize event and updates the width and height whenever the window is resized.

Usage

import React from "react";
import { useWindowSize } from "react-mkx-toolkit";

const MyComponent = () => {
  const { width, height } = useWindowSize();
  return (
    <div>
      <h1>Window Dimensions</h1>
      <p>Width: {width}px</p>
      <p>Height: {height}px</p>
    </div>
  );
};
export default MyComponent;

Features

• Tracks window.innerWidth and window.innerHeight in real-time.
• Automatically updates when the browser window is resized.
• Lightweight and easy to use.
