在Sails.js中使用load-grunt-config

Question

Context

I have a few grunt tasks that I've already written, and I'd like to use them with a new project I'm writing in Sails.js.

With Sails.js, you can add additional grunt tasks by adding a JS file to the /tasks/register folder. Before we get to the file I've added, let's talk about the problem.

The Problem

Sails won't lift. Debugger shows:

debug: --------------------------------------------------------
error: ** Grunt :: An error occurred. **
error: 
------------------------------------------------------------------------
ERROR
>> Unable to process task.
Warning: Required config property "clean.dev" missing. 

The issue in question is obviously with grunt, so then I try grunt build (which automatically runs with sails lift ):

Running "clean:dev" (clean) task
Verifying property clean.dev exists in config...ERROR
>> Unable to process task.
Warning: Required config property "clean.dev" missing. Use --force to continue.

From this, I've garnered that this is a path issue. Let's take a look at the file I've added.

/tasks/register/customTask.js

The task here loads load-grunt-config , which is the source of my problems:

module.exports = function(grunt) {

    // measures the time each task takes
    require('time-grunt')(grunt);

    // This require statement below causes my issue
    require('load-grunt-config')(grunt, {
        config: '../../package.json',
        scope: 'devDependencies',
        overridePath: require('path').join(process.cwd(), '/asset-library/grunt')
    });

    grunt.registerTask('customTask', [
        'newer:jshint',
        'newer:qunit',
        'newer:concat',
        'newer:cssmin',
        'newer:uglify'
    ]);

};

I had assumed that using overridePath instead of configPath would solve my issue, but alas, it's not quite that simple. Is there some way to make it so that I can use my own custom tasks folder with load-grunt-config like I've done in other projects, or is there some magic conditional I can wrap the require statement around?

I only need it to run with grunt customTask , and not run with grunt * (anything else).

Answer 1

Okay, this was actually pretty easy. All I had to do was change the grunt.registerTask call in my customTask.js file from this:

grunt.registerTask('customTask', [
    'newer:jshint',
    'newer:qunit',
    'newer:concat',
    'newer:cssmin',
    'newer:uglify'
]);

to this:

grunt.registerTask('customTask', 'My custom tasks', function() {
    // The require statement is only run with "grunt customTask" now!
    require('load-grunt-config')(grunt, {
        config: '../../package.json',
        scope: 'devDependencies',
        overridePath: require('path').join(process.cwd(), '/asset-library/grunt')
    });
    grunt.task.run([
        'newer:jshint',
        'newer:qunit',
        'newer:concat',
        'newer:cssmin',
        'newer:uglify'
    ]);
});

In case it's not clear, I did have to move the require('load-grunt-config') call, so if you're copy + pasting, make sure to remove the require statement that's outside the grunt.registerTask call.
