How to write file if parent folder doesn’t exist with Node.js?

To write file if parent folder doesn’t exist with Node.js, we use the fs-extra module.

For instance, we write

const fs = require("fs-extra");
const file = "/tmp/this/path/does/not/exist/file.txt";

fs.outputFile(file, "hello!", (err) => {
  console.log(err);

  fs.readFile(file, "utf8", (err, data) => {
    console.log(data);
  });
});

to call the outputFile method to write 'hello!' to the file path.

And then we call readFile to read the file path in the outputFile callback.
