const mkdirp = require('mkdirp');
const path = require('path');

mkdirp(path.join(__dirname, 'foo/bar'), err => {

});

fs-create.js

const path = require('path');
const fs = require('fs');

// cat ./my-file > ./my-other-file
fs.createReadStream(path.join(__dirname, 'my-file'))
  .pipe(fs.createWriteStream(path.join(__dirname, './my-other-file')));

fs-find-current.js

const readdirp = require('readdirp');
const json = require('JSONStream');
const path = require('path');

// recursively print out all files in all subdirectories to the command line.

  .pipe(json.stringify())
  .pipe(process.stdout);

fs-find-parent.js

const findup = require('findup');
const path = require('path');

// recurse up all files relative to __dirname and find all `package.json` files.
findup(path.join(__dirname), 'package.json', (err, res) => {
  if (err) throw err;
  
  console.log('dir is: ' + res);
});

fs-read.js

const fs = require('fs');

// read a file and pipe it to the console
fs.createReadStream(path.join(__dirname, 'my-file'))
  .pipe(process.stdout);

fs-ref.js

const path = require('path');

// find a file relative to the call site, useful for CLI applications and reading files passed in by the user
path.join(process.cwd(), 'my-dynamic-file');

// find a file relative to the file, useful for referencing files that are distributed with the package
path.join(__dirname, 'my-package-file');
