What is the correct way to use readdirSync?

Question

Node.js

There is the following code:

app.get("/data", (req, res) => {
  const files = fs.readdirSync(path.join(__dirname, "uploads"))
  const array = []
  files.forEach(file => {
    array.push(file.fileName)
  })
  res.send(JSON.stringify({"arr": array}))
})

In it, I want to send file names to the page, but I get an empty array. As far as I understand, readdirSync returns an array with files, therefore, I use the fileName method that files have, but for some reason it does not work out. How can this be fixed?

Answer 1

need to use asynchronous method

fs.readdir(path.resolve(__dirname, "uploads"), (err, files) => {
  console.log(files)
})

and in the callback do what you need with the files
and handle errors
