write file to folder nodejs code example

Example 1: javascript fs write file with folder

var path = require('path'),
    fs = require('fs');

function ensureDirectoryExistence(filePath) {
  var dirname = path.dirname(filePath);
  if (fs.existsSync(dirname)) {
    return true;
  }
  ensureDirectoryExistence(dirname);
  fs.mkdirSync(dirname);
}

Example 2: create directory when writing to file in nodejs

fs.mkdir now accepts a { recursive: true } option like so:

// Creates /tmp/a/apple, regardless of whether `/tmp` and /tmp/a exist.
fs.mkdir('/tmp/a/apple', { recursive: true }, (err) => {
  if (err) throw err;
});
