shrub

Shrub

Manipulate lists of files recursively in Node. Chainable API with a promise ending.

Install

npm install shrub --save

Usage

var shrub = require('shrub');

shrub('path/to/dir')
  .each(function (filePath, stats, next) {
    // Do something here
    next();
  })
  .filter(function (filePath, stats, next) {
    // Works the same as Array.prototype.filter
    next(true);
  }).then(function (files) {
    // All done
  });

Methods

each(callback)

Asynchronous loop through file tree Returns an array. The next callback takes no arguments.

shrub('path/to/dir').each(function (filePath, stats, next) {
  next();
}).then(function (files) {

});

filter(callback)

Aynchronously filter the file tree. Returns an array. The next callback takes a truthy value and will filter similar to Array.prototype.filter.

shrub('path/to/dir').filter(function (filePath, stats, next) {
  var isValidSize = stats.size < 10000;
  next(isValidSize);
}).then(function (filteredFiles) {
  
});

find(callback)

Asynchronously find a single item in the files true. Returns a single object. The next callback takes a truth value and will return the first item in the file list that is true.

shrub('path/to/dir').find(function (filePath, stats, next) {
  var isFile = stats.name ='somefile.js';
  next(isFile);
}).then(function (file) {
  
});

then(callback)

Promise-looking callback after all the manipulation methods have fun. Receives a files value as the only arguments (is a single object of a file if the last manipulation method is filter).

var s = shrub('path/to/dir')
  .each(function (filePath, stats, next) {
    // Do something here
    next();
  })
  .filter(function (filePath, stats, next) {
    next(stats.size < 1);
  });

// Then, somewhere else.
s.then(function (files) {
  // All done
});
