Webkernel Composer Merger

Composer plugin to merge multiple composer.json files at runtime —
Webkernel edition with bundled core dependencies for the entire ecosystem.

What is this?

Webkernel Composer Merger is a fork of wikimedia/composer-merge-plugin extended for the Webkernel ecosystem.

It does two things in one package:

• Merges multiple composer.json files at Composer runtime — bootstrap/composer.json, module-level configs, sub-packages
• Bundles all core dependencies required by the Webkernel ecosystem so that individual modules and applications never need to redeclare them

The result: your root composer.json requires exactly one package. Everything else flows from there.

Bundled dependencies

Package	Version
laravel/framework	^12.0
filament/filament	^5.0
laravel/octane	^2.12
laravel/sanctum	^4.0
laravel/tinker	^2.10.1
laravel/prompts	^0.3.8
calebporzio/sushi	^2.5
jeremykendall/php-domain-parser	^6.4
nikic/php-parser	^5.7

Requirements

• PHP ^8.4
• Composer ^2.0

Installation

composer require webkernel/composer-merger

Root composer.json

Your root composer.json should look like this:

{
    "name": "webkernel/webkernel",
    "type": "project",
    "require": {
        "webkernel/composer-merger": "^0.1.0"
    },
    "scripts": {
        "post-autoload-dump": [
            "Illuminate\\Foundation\\ComposerScripts::postAutoloadDump",
            "@php artisan package:discover --ansi"
        ],
        "w-clear": ["... clears all Laravel, Filament, icon caches ..."],
        "w-cache": ["... warms all caches after clearing ..."],
        "dev":     ["... starts server, queue, pail, vite concurrently ..."],
        "test":    ["... runs the test suite ..."]
    },
    "extra": {
        "merge-plugin": {
            "include": [
                "bootstrap/composer.json",
                "modules/**/**/**/composer.json"
            ],
            "recurse": false,
            "replace": false,
            "ignore-duplicates": false,
            "merge-dev": true,
            "merge-extra": true,
            "merge-extra-deep": true,
            "merge-scripts": true
        }
    },
    "config": {
        "optimize-autoloader": true,
        "preferred-install": "dist",
        "sort-packages": true,
        "allow-plugins": {
            "pestphp/pest-plugin": true,
            "php-http/discovery": true,
            "webkernel/composer-merger": true
        }
    },
    "minimum-stability": "stable",
    "prefer-stable": true
}

bootstrap/composer.json

The bootstrap file handles autoload namespaces, Laravel extra config, dev dependencies, second-level module merge and specific webkernel versions dependencies if any. It does not redeclare anything already bundled by this plugin.

{
    "require": {},
    "autoload": {
        "psr-4": {
        }
    },
    "extra": {
        "laravel": {
            "dont-discover": []
        }
    }
}

How the merge chain works

root composer.json
  └── requires webkernel/composer-merger        → brings all core deps transitively
  └── merge-plugin includes:
        ├── bootstrap/composer.json              → autoload, Laravel config, dev deps
        └── modules/**/**/composer.json          → each module's own deps & providers

Composer processes this in a single composer install. No two-step install, no manual merging.

Plugin configuration reference

All settings live under the merge-plugin key in your extra section.

include

Glob patterns pointing to composer.json files to merge. The following sections are merged as though declared directly in the root: require, require-dev, autoload, autoload-dev, conflict, provide, replace, repositories, suggest, extra, scripts.

require

Same as include but throws an error if a pattern matches no file.

recurse

Default true. If a merged file itself contains a merge-plugin section it will also be processed. Set to false to disable.

replace

Default false. When true, last version found wins for duplicate package declarations across merged files.

ignore-duplicates

Default false. When true, first version found wins. Mutually exclusive with replace — if both are set, ignore-duplicates takes precedence.

merge-dev

Default true. Set to false to skip merging require-dev and autoload-dev sections.

merge-extra

Default false. Set to true to merge extra sections. Combine with merge-extra-deep: true for deep recursive merge.

merge-replace

Default true. Set to false to skip merging replace sections.

merge-scripts

Default false. Set to true to merge scripts sections. Note: merged custom commands are available via composer run-script my-command but not as composer my-command shortcuts.

Running tests

composer install
composer test
