walkdir-hash

Stream all filenames in a dir (recursively) and receive the filename, stat and your specified hash for each file.

Builds on walkdir except you can specify a hash type (e.g. md5, sha1, sha256) which should be performed on each file.

Unlike walkdir which returns an event emitter, walkdir-hash returns a stream in object mode. Hence you can listen for data events, error events and the end event.

Synopsis

var walk = require('walkdir-hash');

var stream = walk('files', 'md5');
stream.on('data', console.log);
stream.on('error', console.warn);
stream.on('end', function() {
    console.log('Ended');
});

For the files files/hello-world.txt and files/file.json, you will get two data events.

The output might look like:

{ filename: '/home/chilts/src/chilts-walkdir-hash/test/files/file.json',
  stat:
   { dev: 19,
     mode: 33204,
     nlink: 1,
     uid: 1000,
     gid: 1000,
     rdev: 0,
