fs-mkdirp-stream

Ensure directories exist before writing to them.

Usage

var to = require('to2');
var from = require('from2');
var mkdirpStream = require('fs-mkdirp-stream');

from.obj([{ dirname: '/path/to/my/', path: '/path/to/my/file.js' }])
  .pipe(mkdirpStream.obj(function(obj, callback) {
    // callback can take 3 arguments (err, dirname, mode)
    callback(null, obj.dirname);
  }))
  .pipe(to.obj(function(obj) {
    // This will be called once the directory exists
    // obj === { dirname: '/path/to/my/', path: '/path/to/my/file.js' }
  }));

API

mkdirpStream(resolver)

Takes a resolver function or string and returns a through2 stream.

If the resolver is a function, it will be called once per chunk with the signature (chunk, callback). The callback(error, dirpath, mode) must be called with the dirpath to be created as the 2nd parameter or an error as the 1st parameter; optionally with a mode as the 3rd parameter.

If the resolver is a string, it will be created/ensured for each chunk (e.g. if it were deleted between chunks, it would be recreated). When using a string, a custom mode can't be used.

mkdirpStream.obj(resolver)

The same as the top-level API but for object streams. See the example to see the benefit of object streams with this module.
