This is a package aimed at Node.js development tools. It provides a list of directories that should probably be ignored by such tools, e.g. when watching for file changes.
npm install --save ignore-by-default
The ignore-by-default module exports a directories() function, which will
return an array of directory names. These are the ones you should ignore.
// ['.git', '.sass_cache', …]
var ignoredDirectories = require('ignore-by-default').directories()
