    You need to import file system module:

    const fs = require('fs');
// ...

fs.readFile('...')

    In nodeJS if you want to do operation(Read, Write etc.) on files you have to use file system module provided by nodeJS.
    Before using this module you have to import(ES6) or require it.
    You can take reference from below how to use file system in node js

    const fs = require('fs')
fs.readFile('Demo.txt', 'utf8', function(err, data){
  
// Display the file content
console.log(data);
});
