Simple (recursive) file finder. Designed to find files (not directories). Has simple filtering functionality built in for filtering by file and directory.

/*Imagine this structure:

  lib/
    file.js
    other.md
    module/
      file.js
      other.js

*/

var MatchFiles = require('match-files');

//1st is path, 2nd is options, 3rd is callback
MatchFiles.find(__dirname + '/lib', {}, function(err, files){
  //following standard node conventions

  console.log(files);
  //will output (in absolute paths)
  //Paths are *not* sorted so they may not appear
  //in the order you expect
  //['lib/file.js', 'lib/other.md' 'lib/module/file.js', 'lib/module/other.js']
});

var MatchFiles = require('match-files');

//You can filter by file and by directory.
//If a directory is filtered files and directories under the
//filtered directory will *not* be searched.

function matchJsFiles(path){
  //paths are relative to the 'basepath' which is the initial
  //path set or the .basepath option given
}

function excludeModuleDir(path){
  //Exclude all directories named module (and their children)
  return !path.match(/\/module/);
}

MatchFiles.find(__dirname + '/lib', {
  fileFilters: [matchJsFiles], //always an array of functions
  directoryFilters: [excludeModuleDir]
}, function(err, files){
  console.log(files);
  //['lib/file.js']
});

Note: the object given for options will be modified. I use file filters to exclude certain file types and directory filters to exclude things like .svn or .git.

{
  //String used to create relative paths for filters
  basepath: (default the path used for find) ,

  //Default an empty array. Used for recursion you can
  //pass an array of files to use as a base.
  files: [],

  //An array of functions that must return true for the 
  //file to be included in the results. Recieves a path relative to
  //base root as an argument.
  fileFilters: null,

  //An array of functions that must return true for the 
  //file to be included in the results. Recieves a path relative to
  //base root as an argument.
  directoryFilters: null
