Create task in grunt in another file - gruntjs

Question

I wrote simple task in Grunt. Now, I would like to export this task to another file, and I have a problem with it.
How can I find file with my task? This task just searches string from website and putting it in the file. I'm trying load it by: grunt.loadTasks('grunt-find');
I have file (grunt-find) with find.js inside. But it doesn’t work... Can I have to add find.js somewhere else?
Thanks in advance.

Answer 1

grunt.loadTask() will load every JS file in the directory provided as argument; so, basically, you have to do something like:
grunt.loadTasks("tasks");
and you may have a directory called "tasks":
project root
|- tasks
|--- file.js
|- Gruntfile.js

Answer 2

If you find the "directory only" behavior of grunt.loadTask() annoying (i.e. want to keep external tasks definitions next to external task configuration), you can try something like that :
module.exports = function(grunt) {
var env = process.env.NODE_ENV || 'dev';
var _ = require('lodash');
/*** External config & tasks filepaths ***/
//we have 1 base config, and possibly many module-specific config
var configLocations = ['./grunt-config/default_config.js', './grunt-config/**/config.js'];
//we have 1 base tasks definition, and possibly many module-specific config
var tasksLocations = ['./grunt-config/default_tasks.js', './grunt-config/**/tasks.js'];
