grunt-execute
Grunt plugin to execute code in node
Getting Started
This plugin requires Grunt ~0.4.1
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-execute --save-dev
Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:
grunt.loadNpmTasks('grunt-execute');
The "execute" task
Execute javascript files and snippets to test application files, run loose bits development javascript or use basic files as a poor-mans grunt-tasks.
- Run selected files in a node.js child process.
- Run inline functions with grunt/options helpers and async support.
- Run functions before/after looping the selected files.
- Require() selected files as custom callback module.
The callback module file and inline functions all share the same signature with access to grunt, options and optional async callback.
Overview
In your project's Gruntfile, add a section named execute
to the data object passed into grunt.initConfig()
.
grunt.initConfig({
execute: {
target: {
src: ['script.js']
}
}
})
Options
Also see the Gruntfile.js for real usage examples.
grunt.initConfig({
execute: {
simple_target: {
// execute javascript files in a node child_process
src: ['script.js']
},
simple_target_with_args: {
options: {
// execute node with additional arguments
args: ['arg1', 'arg2']
},
src: ['script.js']
},
simple_target_with_harmony: {
options: {
// pass arguments to node itself (eg: before script parameter)
nodeargs: ['--harmony']
},
src: ['script.js']
},
cwd_target: {
options: {
// overide code cwd (defaults to '.' for project main)
cwd: '.'
},
src: ['script.js']
},
glob_target: {
// supports grunt glob and filter features
src: ['apps/**/*.js', 'lib/**/index.js']
},
module_target: {
options: {
// use require() instead of a child_process
// the scripts must be a module exporting a function
// use a signature like the inline call-option (see below)
module: true
},
src: ['script.js']
},
callback_sync: {
// simple inline function call
call: function(grunt, options){
grunt.log.writeln('Hello!');
}
},
callback_async: {
// function call also supports async callback
call: function(grunt, options, async){
// get the callback
var done = async();
setTimeout(function(){
grunt.log.writeln('Done!')
done(err);
}, 1000);
}
}
before_after: {
options: {
// like call but executed before/after looping the files
before: function(grunt, options){
console.log('Hello!');
},
after: function(grunt, options){
console.log('Bye!');
}
},
// can also be used outside the options
before: function(grunt, options){
console.log('Hello!');
},
after: function(grunt, options){
console.log('Bye!');
}
src: ['script.js'],
},
}
});

Contributing
In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
