grunt-wordpress

Grunt plugin for publishing content to WordPress

Support this project by donating on Gittip.

Getting Started

grunt-wordpress works just like any other Grunt plugin. However, only Grunt 3.x is currently supported. See the Config section for details on setting up the Grunt tasks.

Make sure to copy grunt-wordpress.php in to your WordPress install as a plugin.

Resources are uploaded to /gw-resources/{HOME_URL}/. If you'd like a friendlier name, you can set up a redirect in your web server.

If you have problems uploading resources, check the Permissive Uploads section.

Node.js API

For most projects, you should only need to specify the wordpress config and use the wordpress-deploy task (or its alias deploy).

Config

grunt.initConfig({
	wordpress: {
		url: "wordpress.dev",
		username: "admin",
		password: "admin",
		dir: "dist"
	}
});

This works for a single deployment target. If you have multiple targets, you can specify url, username and password for each:

grunt.initConfig({
	wordpress: {
		dev: {
			url: "wordpress.dev",
			username: "admin",
			password: "admin",
		},
		live: {
			url: "wordpress.com",
			username: "admin",
			password: "admin",
		},
		_default: "dev",
		dir: "dist"
	}
});

If nothing is specified, the _default target is used. Override using the target task:

grunt target:live deploy

url: The URL for the WordPress install. Can be a full URL, e.g., http://wordpress.dev:123/some/path or as short as just the host name. If the protocol is https, then a secure connection will be used.
username: WordPress username.
password: WordPress password.
dir: Directory containing posts, taxonomies, and resources (see Directory Structure).
_default: The default deployment target, optional.

Directory Structure

The wordpress.dir directory has the following structure:

dir
├── posts
│   └── <post_type>
│       └── <post_name>.html
├── resources
│   └── <file>.<ext>
└── taxonomies.json

The posts directory must only contain <post_type> directories. The <post_type> directories must be named to exactly match a post type, e.g., post or page. All custom post types are supported.

The resources directory is completely freeform. Resources of any type will be uploaded based on the current directory structure.

taxonomies.json

The taxonomies.json file defines all used taxonomy terms. You can only manage terms, all taxonomies much already exist in WordPress.

{
	"<taxonomy_name>": [
		{
			"name": "My Term",
			"description": "My term is awesome",
			"slug": "my-term"
		},
		{
			"name": "My Other Term",
			"slug": "my-other-term",
			"children": [
				{
					"name": "I'm a child term!",
					"slug": "hooray-for-children"
				}
			]
		}
	]
}

Slugs and names are required.

Post Files

Post files must be HTML, containing the content of the post. Post data can be specified as JSON in a <script> element at the top of the file.

<script>{
	"title": "My Post",
	"termSlugs": {
		"<taxonomy_name>": [
			"<hierarchical_slug>"
		]
	}
}</script>
<p>I'm a post!</p>

The post type and parent are determined based on the directory structure. termSlugs must match a hierarchical slug defined in taxonomies.json.

Tasks

wordpress-validate

Walks through the wordpress.dir directory and performs various validations, such as:

Verifying that XML-RPC is enabled for the WordPress site.
Verifying that the custom XML-RPC methods for grunt-wordpress are installed.
Verifying the taxonomies and terms in taxonomies.json.
Verifying that child-parent relationships for posts are valid.
Verifying data for each post.

wordpress-sync

Synchronizes everything in wordpress.dir to the WordPress site. This will create/edit/delete terms, posts, and resources.

Note: wordpress-validate must run prior to wordpress-sync.

wordpress-publish

Alias task for wordpress-validate and wordpress-sync. This is useful if your original source content is already in the proper format, or if you want to manually verify generated content between your custom build and publishing.

wordpress-deploy

Alias task for build-wordpress and wordpress-publish. This is useful if you are generating content for use with wordpess-sync. Simply create a build-wordpress task that populates the wordpress.dir directory and your deployments will be as simple as grunt wordpress-deploy.

deploy

Alias task for wordpress-deploy. Since most projects that use grunt-wordpress only have one deploy target (WordPress), there is a built-in deploy task that just runs wordpress-deploy. If your project has multiple deploy targets, you can simply re-alias the deploy task.

Helpers

wordpress-recurse( path, callback, complete )

Walks through all files in path (asynchronous and in series ).

path: The directory to walk through.
callbak (function( filepath, callback )): Callback to invoke for each file.
- filepath: Path to the current file.
- callback: A callback to invoke after processing the file. Passing an error will stop the helper.
complete: (function( error )): Callback to invoke after walking all files.

wordpress-client()

wordpress-validate-xmlrpc-version( callback )

Verifies that the XML-RPC extensions for grunt-wordpress are installed in WordPress.

callback (function( error )): Callback to invoke after verifying.

wordpress-validate-terms( path, callback )

path: The path to the taxonomies JSON file.
callback (function( error )): Callback to invoke after validating the terms.

wordpress-validate-posts( path, callback )

path: The directory of posts to validate.
callback (function( error )): Callback to invoke after validating the posts.

wordpress-get-postpaths( callback )

If an error is encountered while parsing the post data or from a callback, the helper will stop walking through posts and immediately invoke the complete callback with the error.

Permissive Uploads

Depending on what resources you're uploading, you may need to change some WordPress settings. Here are a few settings that might help:

// Disable more restrictive multisite upload settings.
remove_filter( 'upload_mimes', 'check_upload_mimes' );

// Give unfiltered upload ability to super admins.
define( 'ALLOW_UNFILTERED_UPLOADS', true );

// Allow additional file types.
add_filter( 'upload_mimes', function( $mimes ) {
	$mimes[ 'eot' ] = 'application/vnd.ms-fontobject';
	$mimes[ 'svg' ] = 'image/svg+xml';
	$mimes[ 'ttf' ] = 'application/x-font-ttf';
	$mimes[ 'woff' ] = 'application/font-woff';
	$mimes[ 'xml' ] = 'text/xml';
	$mimes[ 'php' ] = 'application/x-php';
	$mimes[ 'json' ] = 'application/json';
	return $mimes;
});

// Increase file size limit to 1GB.
add_filter( 'pre_site_option_fileupload_maxk', function() {
	return 1024 * 1024;
});
