If you need to check if a file exists without opening or modifying with Nodejs, you use fs.access() method.
const fs = require("fs")
fs.access("file.txt", (err) => {
console.log(err ? 'not exist' : 'exist');
}
)
The callback's argument is an Error object if the check fails.
For further actions, you may consider blocking this person and/or reporting abuse
