README

This repository (Gutenberg Packages) manages versions of Gutenberg.

Gutenberg Packages is wrapper of this library.

Gutenberg Packages fetches version data from

1. Library
2. API (daily update)
3. Gutenberg repository

and cache for a day.
(When the state (WP Core version or Gutenberg plugin state) changes, the cache is cleared).

Installation

composer require technote/gutenberg-packages

Usage

<?php
use Technote\GutenbergPackages;

$packages = new GutenbergPackages();

$packages->is_block_editor(); // true or false
$packages->get_gutenberg_version(); // e.g. 6.0.0 (empty string if Gutenberg plugin is not activated)

$packages->get_editor_package_versions(); // array of (package => version), false if block editor is invalid
/** e.g.
[
  "wp-a11y"        => "2.0.2",
  "wp-annotations" => "1.0.8",
  "wp-api-fetch"   => "2.2.8",

  ...

  "wp-url"         => "2.3.3",
  "wp-viewport"    => "2.1.1",
  "wp-wordcount"   => "2.0.3"
]
*/

$packages->get_editor_package_version( 'wp-editor' ); // e.g. 9.0.11
$packages->get_editor_package_version( 'editor' ); // same as above

$packages->is_support_editor_package( 'wp-editor' ); // true or false
$packages->is_support_editor_package( 'editor' ); // same as above

$packages->filter_packages( [
	'editor',
	'wp-editor',
	'test-package',
	'components',
	'wp-data',
	'wp-data',
] );
/** e.g.
[
	'wp-editor',
	'wp-components',
	'wp-data',
]
*/

$packages->fill_package_versions( [
	'editor',
	'wp-editor',
	'test-package',
	'components',
	'wp-data',
	'wp-data',
] );
/** e.g.
[
	'wp-editor'     => '9.0.11',
	'wp-components' => '7.0.8',
	'wp-data'       => '4.2.1',
]
*/

Motivation

There is no WP Core function to get version of Block Editor packages.
So it is hard to consider compatibility.

For example
Gutenberg v5.9 outputs message bellow.

wp.editor.BlockFormatControls is deprecated and will be removed. Please use wp.blockEditor.BlockFormatControls instead.

If your plugin uses wp-block-editor package like bellow, you get an error under WP v5.2.

const { BlockFormatControls } = wp.blockEditor;

Uncaught TypeError: Cannot destructure property `BlockFormatControls` of 'undefined' or 'null'.

From JavaScript, to check existence of property can solve this problem easily.

const { BlockFormatControls } = wp.blockEditor && wp.blockEditor.BlockEdit ? wp.blockEditor : wp.editor;

But you also need to know package validity from PHP because wp_enqueue_script needs dependencies.
If you pass wp-block-editor to wp_enqueue_script under WP v5.2, script is not enqueued.

<?php
wp_enqueue_script( 'test-script', 'path/to/javascript/index.js', [
	'wp-block-editor',
	'wp-components',
	'wp-compose',
	'wp-element',
	'wp-editor',
	'lodash',
] );

This library can help this problems.

<?php
use Technote\GutenbergPackages;

$packages = new GutenbergPackages();
wp_enqueue_script( 'test-script', 'path/to/javascript/index.js', $packages->filter_packages( [
	'wp-block-editor',
	'wp-components',
	'wp-compose',
	'wp-element',
	'wp-editor',
], [ 'lodash' ] ) );

If you use under WP v5.1, wp-block-editor is filtered.
And if you use over WP v5.2, wp-block-editor is not filtered.

You can also pass the package versions to JavaScript via wp_localize_script.

<?php
use Technote\GutenbergPackages;

$packages = new GutenbergPackages();

$depends = [
	'wp-block-editor',
	'wp-components',
	'wp-compose',
	'wp-data',
	'wp-element',
	'wp-editor',
];
wp_enqueue_script( 'test-script', 'path/to/javascript/index.js', $packages->filter_packages( $depends, [ 'lodash' ] ) );
wp_localize_script( 'test-script', 'PackageVersions', $packages->fill_package_versions( $depends) );

// JavaScript
console.log( PackageVersions );
