How to import all tasks from another gulp file.js

Does it possible to have one main gulpfile.js from which to call tasks from other gulp files.js? Simple "require" of child gulpfile.js into main one doesn't work. I have a platform project which includes several sub projects with separate gulpfiles, so I need a solution to manage all child gulpfiles from within main one

It is possible to have one main gulpfile.js from which to call tasks from other gulp files.js using the require-dir module. From the projects README use it like this:

Split tasks across multiple files

If your gulpfile.js is starting to grow too large, you can split the tasks into separate files by using the require-dir module.

Imagine the following file structure:

gulpfile.js
tasks/
├── dev.js
├── release.js
└── test.js

Install the require-dir module:

npm install --save-dev require-dir

Add the following lines to your gulpfile.js file.

var requireDir = require('require-dir');
var dir = requireDir('./tasks');
