grunt-fail-fast-task-runner

A Grunt task to run tasks on multiple Grunt projects that will exit immediately on failure (fail fast)

Getting Started

This plugin requires Grunt.

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-fail-fast-task-runner --save-dev

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

grunt.loadNpmTasks('grunt-fail-fast-task-runner');

The "fail_fast_task_runner" task

Overview

The fail_fast_task_runner task is for running tasks on multiple projects. It would like to know which Gruntfiles to use and which tasks to run on each Grunt project. For example if you would like to lint and test on every Grunt project one folder up

grunt.initConfig({
  fail_fast_task_runner: {
    all: {
      src: ['../*/Gruntfile.js'],
      tasks: ['jshint', 'nodeunit'],
    }
  },
});

Options

options.concurrency

Type: Number Default value: 1

An integer for determining how many worker functions should be run in parallel.

Usage Examples

Default Options

In this example, the default options are used to run tasks on multiple projects. So running fail_fast_task_runner:build will run the buildtask over all Gruntfiles, and running fail_fast_task_runner:all will run the tasks dev and tasks. If there is no argument passed after fail_fast_task_runner, all configurations are executed. If no tasks are defined, it will default to the default task.

grunt.initConfig({
  fail_fast_task_runner: {
    options: {},
    build: {
      src: ['*/Gruntfile.js'],
      tasks: ['buildtask']
    },
    all: {
      src: ['*/Gruntfile.js'],
      tasks: ['dev', 'tasks']
    }
  },
})

Custom Options

In this example, custom options are used to run with a concurrency of 5.

grunt.initConfig({
  fail_fast_task_runner: {
    options: {
      concurrency: 5
    },
    build: {
      src: ['*/Gruntfile.js'],
      tasks: ['buildtask']
    },
    all: {
      src: ['*/Gruntfile.js'],
      tasks: ['dev', 'tasks']
    }
  },
})
