First, import stat
from the NodeJS standard library:
import { stat } from "node:fs/promises";
Async-await style
// Async-await style: const statResult = await stat("myfile.pdf"); const fileSizeInBytes = statResult.size;
Promise.then() style
stat("myfile.pdf").then(statResult => { const fileSizeInBytes = statResult.size; // TODO your code goes here });
