Gulp-add-tasks2 NPM

`gulp-add-tasks2`

A utility to dynamically add tasks based on a specified task structure to a passed-in instance of gulp.

Integrates with gulp-help and run-sequence to provide a more robust user experience, as well as the ability to run tasks synchronously

*this module fork from gulp-add-tasks

Install

npm i gulp-add-tasks2 --save-dev

Usage

const gulp = require('gulp');
const addTasks = require('gulp-add-tasks2').init(gulp);

addTasks(...taskLists)

other way import

const addTasks = require('gulp-add-tasks2').init(gulp, parentTaskName);
const addTasks = require('gulp-add-tasks2/node')(gulp, parentTaskName);

import gulpAddTasks from 'gulp-add-tasks2';
import { gulpAddTasks } from 'gulp-add-tasks2';

const addTasks = gulpAddTasks(gulp, parentTaskName);

Task list structure

Task list accepts two object structures, one for "multi-tasks" and one for simple task and function pairs, both of which assume each key in the map as the gulp task name.

multi-task structure

Name	Description
`tasks`	An array of tasks, passed directly to `run-sequence`
`description`	A task description, used by `gulp-help`
`options`	Programmatic options to be utlized by the tasks, used by `gulp-help`
`aliases`	An array of aliases that the task can be called with, used by `gulp-help`
`deps`	An array of tasks to be executed and completed before your task will run.
`callback`	The function performs the task's main operations. Generally this takes the form of:

Example

const gulp = require('gulp');
const addTasks = require('gulp-add-tasks2').init(gulp);

addTasks({
  build: {
    description: 'Build application for distribution',
    tasks: [
      ['sass', 'babel']
    ],
    options: {
      production: 'Minify assets with this flag'
    }
  }
});

gulp build will now be a runnable task via the CLI, which will, in turn, call gulp sass & gulp babel (async) via run-sequence.

single task structure

A simple key/value pair, with the key representing the task name, and the value a reference to a function, can be used to create a simple task. This is particularly useful when used in conjunction with require-tasks, which generates a structure that can be directly passed to gulp-add-tasks.

Example

const gulp = require('gulp');
const addTasks = require('gulp-add-tasks2').init(gulp);

addTasks({
  babel() {
    const babel = require('gulp-babel');

    return gulp.src('src/**/*.js')
      .pipe(babel({
        presets: ['es2015']
      }))
      .pipe(gulp.dest('dist'));
  }
});

gulp babel will now be a runnable task via the CLI.

Advanced Usage

gulp-add-tasks supports multi-tasks, separating a nested structure via colons (:), e.g.

const gulp = require('gulp');
const addTasks = require('gulp-add-tasks2').init(gulp);

addTasks({
  copy: {
    css() {
      return gulp.src('src/**/*.css')
        .pipe(gulp.dest('dist/css'));
    },
    js() {
      return gulp.src('src/**/*.js')
        .pipe(gulp.dest('dist/js'));
    }
  }
})

gulp will now have the tasks copy:css and copy:js available for usage from the command line.
