@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 IE browsers then using core-js will add polyfills for these methods.
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 __unstableInserterMenuExtension, 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/.
