sails-hook-grunt

Implements support for the built-in asset pipeline and task runner in Sails.

This is a core hook in the Sails.js framework. You can override or disable it using your .sailsrc file or environment variables. See Concepts > Configuration for more information.

Dependencies

In order for this hook to load, the following other hooks must have already finished loading:

Dependents

If this hook is disabled, in order for Sails to load, the following other core hooks must also be disabled:

Purpose

This hook's responsibilities are:

Run a Grunt tasklist when Sails is loaded

When Sails is loaded, this hook spins up a Grunt child process and runs the conventional tasklist. The tasklist to run depends on the environment (sails.config.environment).

This hook will first look for a file in tasks/register/ that corresponds with the environment name (e.g. if your environment is set to 'staging', then Sails will look for a tasklist file named staging.js). If no such tasklist file is found, but environment is production, then the prod tasklist is used (a special case for compatibility). Otherwise, the default Grunt tasklist is used.

Parse and log output

This hook's runTask method binds events to the child process output streams, through which it receives stdout and stderr output from the Grunt child processes and uses several different heuristics to parse it and display at the appropriate log level.

Track Grunt child process for cleanup when Sails shuts itself down

To prevent proc leaks, Sails keeps track of the Grunt child process on sails.childProcesses.

Implicit defaults

This hook sets the following implicit default configuration on sails.config:

N/A

Events

hook:grunt:loaded

Emitted when the Grunt hook has been automatically loaded by Sails core, and triggered the callback in its initialize function.

hook:grunt:done

Emitted when the Grunt child process exits with a normal status code. (in development, this will not fire until the app is lowered, since grunt-contrib-watch keeps the child process active)

This event is experimental. It is very possible that it will change in a future release.

hook:grunt:error

Emitted when the Grunt child process exits with a non-zero status code.

This event is experimental. It is very possible that it will change in a future release.

Methods

sails.hooks.grunt.runTask()

Fork a Grunt child process that runs the specified task.

sails.hooks.grunt.runTask(taskName);

Or:

• sails.hooks.grunt.runTask(taskName, cb);

Usage

	Argument	Type	Details
1	taskName	((string))	The name of the Grunt task(list) to run.
2	cb	((function))	Optional. Fires when the Grunt task has been started (non-production) or finished (production).

API: Private

• Please do not use this method in userland (i.e. in your app or even in a custom hook or other type of Sails plugin).
• Because it is a private API of a core hook, if you use this method in your code it may stop working or change without warning, at any time.
• If you would like to see a version of this method made public and its API stabilized, please open a proposal.

(internally in core, note that this is called directly by sails www in the CLI--see bin/sails-www.js)

FAQ

What is this?

This repo contains a hook, one of the building blocks Sails is made out of.

What version of Sails is this for?

This hook is a dependency of Sails core in Sails v1, and beyond.

Can I disable this hook?

Yes. To disable this hook, merge the following JSON into your app's .sailsrc file:

{
  "hooks": {
    "grunt": false
  }
}

Can I override this hook to use a different asset pipeline like Gulp or Webpack?

Yes. To override this hook, define your replacement hook under your app's api/hooks/ directory. Or, to share your override with the world, publish it on NPM (e.g. @mynpmusername/sails-hook-grunt or sails-hook-webpack). Just be sure to include the following in your package.json:

"sails": {
  "isHook": true,
  "hookName": "grunt"
}

See the package.json file in this repo for reference.
