grunt-wait

Delay the grunt build chain with callbacks

Getting Started

This plugin requires Grunt >=0.4.0

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-wait --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-wait');

The "wait" task

Overview

In your project's Gruntfile, add a section named wait to the data object passed into grunt.initConfig().

grunt.initConfig({
  wait: {
    options: {
      delay: 500
    },
    pause: {
      options: {
        before : function(options) {
          console.log('pausing %dms', options.delay);
        },
        after: function() {
          console.log('pause end');
        }
      }
    },
    random: {
      options: {
        delay: 10,
        after: function() {
          console.log('gamble');
          return Math.random() < 0.05 ? false : true;
        }
      }
    }
  }
})
