I was able to create a promise to get this information using the answer below containing the escape sequence for requesting terminal cursor position:

How can I get position of cursor in terminal?

const getCursorPos = () => new Promise((resolve) => {
    const termcodes = { cursorGetPosition: '\u001b[6n' };

    process.stdin.setEncoding('utf8');
    process.stdin.setRawMode(true);

    const readfx = function () {
        const buf = process.stdin.read();
        const str = JSON.stringify(buf); // "\u001b[9;1R"
        const regex = /\[(.*)/g;
        const xy = regex.exec(str)[0].replace(/\[|R"/g, '').split(';');
        const pos = { rows: xy[0], cols: xy[1] };
        process.stdin.setRawMode(false);
        resolve(pos);
    }

    process.stdin.once('readable', readfx);
    process.stdout.write(termcodes.cursorGetPosition);
})

const AppMain = async function () {
    process.stdout.write('HELLO');
    const pos = await getCursorPos();
    process.stdout.write("\n");
    console.log({ pos });
}

AppMain();
