node-readfiletree

Deserialize an file/directory tree into an object. Available in npm as readfiletree

NPM

Particularly useful for testing where you need to do a deepEqual() on a simple tree of files. See node-mkfiletree for file tree serialization.

require('readfiletree')(directory, callback)

Read the directory and the files it contains, recursively, and return an object representing the directory structure with nodes containing the utf8 string contents of each file. The arguments of the callback are: (err, object).

Using both mkfiletree and readfiletree we can do the following:

require('mkfiletree').makeTemp(
  'testfiles',
  {
    'adir': {
      'one.txt': '1\n2\n3\n',
      'two.txt': 'a\nb\nc\n',
      'deeper': {
        'depths.txt': 'whoa...'
      }
    },
    'afile.txt': 'file contents'
  },
  function (err, dir) {
    require('readfiletree')(dir, function (err, obj) {
      console.log(obj)
    })
  }
)

The directory structre created above looks like the following:

$ find /tmp/testfiles11240-23530-r7rs3 -type f -exec sh -c "echo '\n{}: ' && cat '{}'" \;
  →  /tmp/testfiles11240-23530-r7rs3/afile.txt: 
      file contents
      /tmp/testfiles11240-23530-r7rs3/adir/deeper/depths.txt: 
      whoa...
      /tmp/testfiles11240-23530-r7rs3/adir/two.txt: 
      a
      b
      c

      /tmp/testfiles11240-23530-r7rs3/adir/one.txt: 
      1
      2
      3

And the output of the program should be the same as the input to mkfiletree:

{
  'adir': {
    'one.txt': '1\n2\n3\n',
    'two.txt': 'a\nb\nc\n',
    'deeper': {
      'depths.txt': 'whoa...'
    }
  },
  'afile.txt': 'file contents'
}

Tests can be run with npm test. I'm more than happy to receive contributions so fork away!
