#load-grunt-config
load-grunt-config is a Grunt library that allows you to break up your Gruntfile config by task. For most small projects a single Gruntfile.js is perfect. But as a project grows, the Gruntfile.js can quickly become unmanagable; this is where load-grunt-config comes in handy. It was heavily inspired by Thomas Boyt's "More Maintainable Gruntfiles".
##Features
- Each task has its own config file. Example: jshint.js, mocha.js, etc.
- Auto load all grunt plugins. Uses load-grunt-tasks.
- Auto expose package.json (
<%= package.name %>
). - Support for YAML files.
- Support for coffeescript files.
- Support for returning a function.
- Easily register task aliases with
aliases.(js|yaml|coffee)
. - Config overrides
- Config grouping
##Installation
npm install -D load-grunt-config
##Example
Basic Gruntfile.js
module.exports = function(grunt) {
require('load-grunt-config')(grunt);
};
Gruntfile.js with options
module.exports = function(grunt) {
require('load-grunt-config')(grunt, {
configPath: path.join(process.cwd(), 'grunt'), //path to task.js files, defaults to grunt dir
init: true, //auto grunt.initConfig
data: { //data passed into config. Can use with <%= test %>
test: false
},
loadGruntTasks: { //can optionally pass options to load-grunt-tasks. If you set to false, it will disable auto loading tasks.
pattern: 'grunt-*',
config: require('./package.json'),
scope: 'devDependencies'
}
});
};
###Grunt tasks files
Here's what the files in your grunt/
folder could look like. You can use either .js, .yaml, or .coffee - whatever you prefer and you can mix and match as you see fit.
Example js file returning an object - grunt/watch.js
module.exports = {
all: {
files: [
'<%= jshint.all %>',
'grunt/*.yaml'
],
tasks: [
'default'
]
}
};
Example js file returning a function - grunt/jshint.js
module.exports = function (grunt, options) {
return {
all: [
'Gruntfile.js',
'grunt/*.js',
'lib/*.js',
'test/*.js',
options.someFile
]
};
};
Example yaml file - grunt/notify.yaml
default:
options:
message: 'Default finished'
Example coffee file - grunt/task.coffee
module.exports =
options:
bare: true
###Aliases
If your grunt/
folder contains an aliases.(js|yaml|coffee)
file, load-grunt-config
will use that to define your tasks aliases (like grunt.registerTask('default', ['jshint']);
).
grunt/aliases.yaml
default:
- 'jshint'
- 'mocha'
- 'notify'
There are certain scenarios where you might have a base config for your team, and you want to be able to override some of the config based on your personal setup. You can do that with the overridePath
property. In this case, the library will merge the two, with the override path taking priority. For example:
module.exports = function(grunt) {
require('load-grunt-config')(grunt, {
configPath: path.join(process.cwd(), 'vendor'),
overridePath: path.join(process.cwd(), 'config-'+process.env.USER)
});
};
load-grunt-config
also supports grouping tasks. This is handy when you want to group all of your script or css tasks together. To do that, just add the suffix -tasks
to your config filename and load-grunt-config
will treat the filename as the task target and the top level keys as the task names.
Here's an example
Filename: /config/scripts-tasks.yaml
jshint:
files:
- '*.js'
watch:
files:
- '*.js'
tasks:
- 'scripts'
This would be the equivalent in your Gruntfile.js
:
{
jshint: {
scripts: {
files: [
'*.js'
]
}
},
watch: {
scripts: {
files: [
'*.js'
],
tasks: [
'scripts'
]
}
}
}
