app-root

Returns a list of candidate root files for CommonJS or AMD JavaScript applications within a directory.

A root/entry-point file is one that has dependencies but is not depended on (i.e., no other file requires it).

npm install app-root

This is useful for automatically deducing the entry point for r.js or browserify configurations.

var getAppRoot = require('app-root');

// Find the application roots within the js folder
getAppRoot('./js', function (roots) {
  ...
})

Ignoring particular subdirectories

Supply an options object as the second parameter with a field ignore that contains a list of the directories that you want to ignore when looking for candidate app roots.

Otherwise, you'd end up with junk roots for 3rd party libraries/dependencies.

var options = {
  ignore: ['bower_components', 'vendor', 'node_modules', '.git']
};

getAppRoot('./js', options, function (roots) {
  ...
})
