@wordpress/block-directory Edit

Package used to extend editor with block directory features to search and install blocks.

This package is meant to be used only with WordPress core. Feel free to use it in your own project but please keep in mind that it might never get fully documented.

Installation Installation

Install the module

npm install @wordpress/block-directory --save

This package assumes that your code will run in an ES2015+ environment. If you’re using an environment that has limited or no support for ES2015+ such as lower versions of IE then using core-js or @babel/polyfill will add support for these methods. Learn more about it in Babel docs.

Usage Usage

This package builds a standalone JS file. When loaded on a page with the block editor, it extends the block inserter to search for blocks from WordPress.org.

To do this, it uses the __experimentalInserterMenuExtension, a slot-fill area hooked into the block types list. When the user runs a search and there are no results currently installed, it fires off a request to WordPress.org for matching blocks. These are listed for the user to install with a one-click process that installs, activates, and injects the block into the post. When the post is saved, if the block was not used, it will be silently uninstalled to avoid clutter.

See also the API endpoints for searching WordPress.org: /wp/v2/block-directory/search, and installing & activating plugins: /wp/v2/plugins/.
