gulp-from-config-rg v0.0.7

gulp-from-config-rg

gulp-from-config-rg provides ability to run gulp tasks from configs.

Version for rg stack, fork from https://github.com/nanomen/gulp-from-config

Why

• Team work on the same project without risk of breaking other tasks
• Store multiple typical tasks as configs
• Write clear and specific to application gulpfile and keep routine tasks in configs

Caveats

• tests and linter coverage needed

Install

# Don't forget to install gulp globaly
# $ sudo npm install -g gulp
$ npm install gulp gulp-from-config-rg

As simple as

Install plugins that you need:

# This command will install sass compiler for gulp
$ npm install gulp-sass --save-dev

Write tasks in JSON configs and place them in ./configs or any other folder

// Load gulp and gulp-from-config-rg
var gulp = require('gulp'),
    gulpFromConfig = require('gulp-from-config-rg');

    // Set config files path
    gulpFromConfig.setConfigsPath('configs');

    // Create tasks
    gulpFromConfig.createTasks(gulp);

Run them as any other gulp tasks from console (by task name):

# This command will search for build task and run it
$ gulp build

    /**

     *  Callback function can be triggered on completion of subtasks
     *  Sub task config is passed as parameter
     */

    }

    /**
     *  Define tasks based on configs
     *  Run like normal gulp task 'gulp styles'
     */
    tasks = gulpFromConfig.createTasks(gulp);

    /**
     *  Or if you need to run all of them
     *  pass tasks array to default task
     *  and run 'gulp'
     */
    gulp.task('default', tasks, function() {
