fs.writeFile in a promise, asynchronous-synchronous stuff

Question

I need some help with my code. I\'m new at Node.js and have a lot of trouble with it.

What I\'m trying to do:

1) Fetch a .txt with Amazon products (ASINs) ;<

Answer 1

What worked for me was fs.promises.

Example One:

const fs = require("fs")

fs.promises
  .writeFile(__dirname + '/test.json', "data", { encoding: 'utf8' })
  .then(() => {
    // Do whatever you want to do.
    console.log('Done');
  });

Example Two. Using Async-Await:

const fs = require("fs")

async function writeToFile() {
  await fs.promises.writeFile(__dirname + '/test-22.json', "data", {
    encoding: 'utf8'
  });

  console.log("done")
}

writeToFile()
