I'm trying to get the current cursor position in a nodejs app.
I've tried getCursorPos (https://nodejs.org/api/readline.html#rlgetcursorpos) but that returns the position relative of the input prompt and the value of rows is 0
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();
