I'm using Node.js's readline in an async function, but the input prompt appears on the same line as the question. I want the user's response to start on a new line after the question is displayed. Here is my current code:
JAVASCRIPTasync function IsAgreed() { const rl = readline.createInterface({ input: process.stdin, output: process.stdout }); let options = ['yes', 'y', 'YES', 'Y']; let response = await rl.question('Do you agree to execute ?'); return options.includes(response); }
Current Output:
Do you agree to execute ?| <-- cursor is here
Expected Output:
Do you agree to execute ?
| <-- I need to insert cursor here
I have tried using the default behavior of rl.question, but it doesn't separate the prompt and the input. How can I modify my code so that the user input begins on the next line?

Below is one way to achieve it. Instead of using rl.question with a prompt that displays on the same line, you can first print the question using console.log, and then prompt for input on a new (empty) prompt. For example:
JAVASCRIPTconst readline = require('readline'); async function isAgreed() { const rl = readline.createInterface({ input: process.stdin, output: process.stdout }); // Print the question on its own line console.log('Do you agree to execute ?'); // Use rl.question with an empty prompt so the cursor appears on a new line const response = await new Promise(resolve => { rl.question('', answer => { rl.close(); resolve(answer); }); }); const options = ['yes', 'y', 'YES', 'Y']; return options.includes(response.trim()); } // Example usage: isAgreed().then(agreed => { console.log(`Agreed: ${agreed}`); });
Print the question separately:
By calling console.log('Do you agree to execute ?');
, you print the question and add a newline so that the cursor moves to the next line.
Prompt with an empty string:
Using rl.question('')
provides an empty prompt string, which means the user will start typing their input on the new line immediately.
Promise wrapper:
The input is wrapped in a promise so that you can use await
and handle the response asynchronously.
This approach meets your requirement: the question is printed, and the cursor moves to the next line for input.

Just add \n escape character at the end of question. \n
will insert new line so you can enter the response in the next line of the question.
JAVASCRIPTasync function IsAgreed() { const rl = readline.createInterface({ input: process.stdin, output: process.stdout }); let options = ['yes', 'y', 'YES', 'Y']; let response = await rl.question('Do you agree to execute ?\n'); // Here ✅ return options.includes(response); }
Don't forget to close the readline interface rl.close()
after all actions.
