walk-tree-as-promised

walk(folder, [options]) can walk through your file system. For example to list all files and folders (default implementation) or to compute a hash (See hash-tree-as-promised)

Installation

npm install walk-tree-as-promised --save

Usage

var walk = require('walk-tree-as-promised');

walk(__dirname)
.then(function(files) {
  // files is an array with all the file and subdirectory names
});

Options

• sync Default: false. If you set sync: true, then the synchronous file API functions are used internally. This might be faster on Linux systems. However the function still returns a promise.
• before Default: undefined. function(callback) that is executed before the walking starts
• after Default: undefined. function(result, callback) that is executed after the walking finished
• processDirectory Default: undefined. function(baseDir, relativePath, stat, entries, callback) that is executed for each directory
• processFile Default: undefined. function(baseDir, relativePath, stat, callback) that is executed for each directory

To get a sense of how you can use these functions, have a look at the default implementations.
