gulp task loader

Usage no npm install needed!

<script type="module">
  import agostoneGulpGlass from 'https://cdn.skypack.dev/@agostone/gulp-glass';



Glass is a task loader for gulp, making it possible to organize tasks into files and directories.


  • Organize tasks into files and directories
  • Specifying as many task path(s) as you wish
  • Task aliasing


$ npm install @agostone/gulp-glass --save-dev


Replace the contents of your gulpfile.js with the following:

const Glass = require('@agostone/gulp-glass');
const glass = new Glass(<configuration>);


  • Required: true
  • Type: String|Object

If the configuration parameter is a simple string, it should point to a valid directory containing the task files. Default pattern for finding task files is '**/*.js'.

If the configuration parameter is a plain javascript object, the structure is the following:

  taskPaths: '<path>'|['<path>', '<path>', ...],
  filePattern: '<pattern>',
  sort: <function>,
  nameResolver: <function>
  • Required: true
  • Type: String|Array of strings

Path(s) containing task files.

  • Required: false
  • Type: String
  • Default: '**/*.js'

Pattern describing task files.

  • Required: false
  • Type: Function
  • Default: Task files are ordered by full path/name in an ascending order.

If provided, defines the order used for loading task files. This is a compare function for array.sort(), check the documentation for array.sort for more information.

  • Required: false
  • Type: Function
  • Default: Name of the task is the filename without path and extension.

If provided, will be executed for each individual task file and should return with the desired task name.

For example (default behavior):

    nameResolver: (file) => path.basename(file, path.extname(file))

Task registration

Tasks are automatically loaded and registered by gulp-glass. Loading/registration order is defined by the sort, task names by the nameResolver configuration parameter.


Filename: '/tasks/minify.js'

Task name: minify

Filename: '/tasks/minify.css.js'

Task name: minify.css

Task files

Task files are regular node.js modules, they should export a gulp task function.


'use strict';

const { src, dest } = require('gulp');

module.exports = function() {
  return src('src/*.js')

Task aliasing

To create task aliases you can export an alias property on the gulp task function. The alias should be either a string defining one alias, or an array of string defining multiple aliases. Task aliases always override the name resolver.


'use strict';

const { src, dest } = require('gulp');

module.exports = function() {
  return src('src/*.js')

module.exports.alias = 'taskAlias';
// or
module.exports.alias = ['taskAlias1', 'taskAlias2'];

Running the tests

$ npm run test


  • Lazy loading tasks, only when gulp really needs them
