useCopy

The useCopy hook is a common hook provided by the Hartan library. This hook uses the native web Clipboard API internally to provide the copy functionality on the text provided by user.

This hook is a public hook and available for the users to use.

Code

import { useState } from "react"

export default function useCopy(textToCopy) {

    const [isCopied, setIsCopied] = useState(false);

    async function copyTextToClipboard(text) {
        if ('clipboard' in navigator) {
            return await navigator.clipboard.writeText(text);
        } else {
            return document.execCommand('copy', true, text);
        }
    }

    const handleCopyClick = () => {
        copyTextToClipboard(textToCopy)
            .then(() => {
                setIsCopied(true);
                setTimeout(() => {
                    setIsCopied(false);
                }, 1500);
            })
            .catch((err) => {
                console.log(err);
            });
    }

    return [isCopied, handleCopyClick]
}

Explanation

• As you can see above it uses the useState hook of the React and the native Clipboard API internally.
• It accepts a single parameter, the text to be copied to clipboard, which is provided by the user.

• It returns two things:

  • isCopied : a state value to tell that text is copied.

  • handleCopyClick : the function which contains the copy logic.

Usage

// App.jsx
import snippetStyle from "./Snippet.module.css"
import useCopy from "../../Hooks/Snippet"

export default function Snippet({ snippetSymbol = "$", snippetSymbolState = true, snippetText = "npm i react-hartan", userSnippetStyle, userSnippetTextStyle }) {

    const [isCopied, handleCopyClick] = useCopy(snippetText);

    return (

        <div className={`${snippetStyle.snippet} ${userSnippetStyle}`} onClick={handleCopyClick}>
            <pre>
                <code>
                    <span className={`${snippetStyle.snippetText} ${userSnippetTextStyle}`}>{snippetSymbolState && snippetSymbol} {snippetText}</span>
                    <span>
                        {
                            isCopied ?
