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 or files

Supply an options object as the second parameter.

Supported options:

• ignoreDirectories: list of directory names (strings or regex) to ignore
• ignoreFiles: list of file names (strings or regex) to ignore

Directory or filenames that match elements of the above lists will be ignored when looking for candidate app roots.

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

var options = {
  ignoreDirectories: [/.+_components/, 'vendor', 'node_modules', '.git'],
  ignoreFiles: ['Gruntfile.js']
};

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