React Js Save Textarea Value to Text File

React Js Save Textarea Value to Text File:In ReactJS, you can save a textarea's value to a text file by capturing the input text, creating a Blob (binary large object) with the text data, and then offering it for download. First, use React's state to manage the textarea's content. Next, create an event handler to update the state as the user types. To save to a text file, set up a function that constructs a Blob with the text and creates a download link. When the user clicks the link, the file will be saved. Use built-in JavaScript methods. Finally, attach this function to a button or event trigger

How can I use React js to save the value from a textarea to a text file?
This React.js code defines a simple web application that allows users to save the content of a textarea to a text file. The application uses React's useState hook to manage the textarea's content and updates it as users type. When the "Save to File" button is clicked, the current textarea content is converted to a Blob, creating a text file. It then generates a download link for the file and triggers a click event, prompting the user to save the file as "text-file.txt." This feature is common in text editors and word processors, enabling users to preserve and share their input.

"); const handleTextareaChange = (e) => { setText(e.target.value); }; const handleSaveToFile = () => { const blob = new Blob([text], { type: 'text/plain' }); const url = window.URL.createObjectURL(blob); const a = document.createElement('a'); a.href = url; a.download = 'text-file.txt'; a.click(); window.URL.revokeObjectURL(url); }; return ( <div className='container'> <h3 className='title'>React Js Save Textarea Value To Text File</h3> <textarea className='text-area' value={text} onChange={handleTextareaChange} rows={10} cols={40} placeholder="Enter text here..." /> <br /> <button className='save-button' onClick={handleSaveToFile}>Save to File</button> </div> ); } ReactDOM.render(<App />, document.getElementById("app")); </script>Output of React Js Save Textarea Value to Text File
