Find files. Walks a directory tree emitting events based on what it finds. Presents a familliar callback/emitter/sync interface. Walk a tree of any depth. This is a performant option any pull requests to make it more so will be taken into consderation..

var walk = require('walkdir');
//async with path callback  
  console.log('found: ',path);
//use async emitter to capture more events 
var emitter = walk('../');
  console.log('file from emitter: ', filename);

  console.log('found sync:',path);
//sync just need paths

npm install walkdir

walkdir(path, [options], [callback]) walkdir.sync(path, [options], [callback]);

  • path

    • the starting point of your directory walk
  • options. supported options are

    • general

      "follow_symlinks":false, // default is off  
      "no_recurse":false,      // only recurse one level deep 
      "max_depth":undefined    // only recurse down to max_depth. if you need more than no_recurse 
    • sync only

      "return_object":false, // if true the sync return will be in {path:stat} format instead of [path,path,...] 
      "no_return":false, // if true null will be returned and no array or object will be created with found paths. useful for large listings 
  • callback

    • this is bound to the path event of the emitter. its optional in all cases.


non error type events are emitted with (path,stat). stat is an instanceof fs.Stats

###path fired for everything

###file fired only for regular files

###directory fired only for directories

###link fired when a symbolic link is found

###end fired when the entire tree has been read and emitted.

###socket fired when a socket descriptor is found

###fifo fired when a fifo is found

###characterdevice fired when a character device is found

###blockdevice fired when a block device is found

###targetdirectory fired for the stat of the path you provided as the first argument. is is only fired if it is a directory.

###empty fired for empty directory

error type events are emitted with (path,error). error being the error object returned from an fs call or other opperation.

###error if the target path cannot be read an error event is emitted. this is the only failure case.

###fail when stat or read fails on a path somewhere in the walk and it is not your target path you get a fail event instead of error. This is handy if you want to find places you dont have access too.

the async emitter returned supports 3 methods

###end stop a walk in progress

###pause pause the walk. no more events will be emitted until resume

###resume resume the walk

will not traverse these directories. may be called in the path event handler to ignore dynamically.

var walk = require('walkdir');
var p = require('path');
  // ignore all .git directories. 
  if(p.basename(path) === '.git') {
//cancel a walk in progress within callback. 
var walk = require('walkdir');
//cancel a walk in progress with emitter handle 
var walk = require('walkdir');
var emitter = walk('../');
