gulp-tasks-bootstrap

A simple gulp task loader.

Install

npm install --save-dev gulp-tasks-bootstrap

Usage

Place your tasks in a separate directory, each task is it's own file. Then, in your gulpfile.js require gulp-bootstrap and load your tasks by calling loadTasks.

// ./gulpfile.js
'use strict';

require('gulp-bootstrap')
  .loadTasks('gulp/tasks/**/*.js');

To make a globaly configuration available to all tasks simple use the config function before loading the tasks. What you do with the configuration inside the tasks is entirely up to you.

// ./gulpfile.js
'use strict';

require('gulp-bootstrap')
  .config({sources: 'dir/to/sources'})
  .loadTasks('gulp/tasks/**/*.js');

Task definitions

Task definitions must have either a task function or dependencies to be valid. It's also possible for a task to have a task function and dependencies.

Forcing a task name is purely optional and not advised unless absolutely necessary.

Task names

Tasks are named based on their path relative to the task base directory. For example, let's assume your tasks files are placed within ./gulp/tasks. A file named placed at ./gulp/tasks/task1.js will have a default name of task1 while a file placed at ./gulp/tasks/do/something.js will have a default name of do:something. You can also use a function as the name property which gets called to generate the name. Inside the function the config is available with this.config.

Additionally task names can be forced by exporting a name property in you task file like:

// file ./gulp/tasks/do/something.js
'use strict';

module.exports.name = 'i-am-doing-something'; // This will force the task name to be 'i-am-doing-something'
module.exports.task = function (next) {
  // do something...

  next();
}

or as function

// file ./gulp/tasks/do/something.js
'use strict';

module.exports.name = function () {
  return this.config.prefix + 'i-am-doing-something';
}

module.exports.task = function (next) {
  // do something...

  next();
}

Task functions

The task function to be executed can be either exported directly or as task property. A task property takes precedence over a directly exported function. Inside the function the config is available with this.config.

// file ./gulp/tasks/do/something.js
'use strict';

module.exports.task = function (next) {
  // do something...

  next();
}

or as simple export

// file ./gulp/tasks/do/something.js
'use strict';

module.exports = function (next) {
  // do something...

  next();
}

Task dependencies

Task dependencies can be exported as dependencies property. They dependencies must be either a string (i.e. only one dependency exists) or as array of strings. The dependencies property can also be a function which must return either an array or string. Inside the function the config is available with this.config. Note that dependencies are run by run-sequence, therefore they are run sequentially.

// file ./gulp/tasks/do/something.js
'use strict';

module.exports.dependencies = ['do:something-before'];

or more simplier

// file ./gulp/tasks/do/something.js
'use strict';

module.exports.dependencies = 'do:something-before';

or as function

// file ./gulp/tasks/do/something.js
'use strict';

module.exports.dependencies = function () {
  return 'do:something-before';
};

Task configuration

Tasks will receive a config property which is the config set as bootstrap config. If you export a config property without your task definition is it either used as default (and thus getting overriden by the global config) in case you exported an object or, if you exported a function, the function gets called with the global config as paramenter.

// file ./gulp/tasks/do/something.js
'use strict';

module.exports.config = {
  source: 'default/path/to/sources'
};

module.exports.task = function (next) {

  console.log('my sources are at', this.config.sources);

  // do something...

  next();
};

or as function

// file ./gulp/tasks/do/something.js
'use strict';

module.exports.config = function (config) {

  // you can modify the config here.

  return config;
};

module.exports.task = function (next) {

  console.log('my sources are at', this.config.sources);

  // do something...

  next();
};

Empty tasks

By default gulp-tasks-bootstrap will throw an error when a task file contains neither a task nor a dependencies property. If you want to allow, but ignore, such files instead you can use the ignoreEmpty() function like:

// ./gulpfile.js
'use strict';

require('gulp-bootstrap')
  .ignoreEmpty(true)
  .loadTasks('gulp/tasks/**/*.js');
