CodePudding user response：

You have to just require your module with promises as mentioned below code...

const fs = require("fs").promises;
const text = "File ";

fs.writeFile("node-message.txt", text)
  .then(() => {
    console.log("File Created");
  })
  .catch(() => {
    console.log("File not created");
  });
