Scans the enclosing vendor folder for other packages and generates an autoload file containing an array of the package namespaces and source folders. Then an external application can be powered by multiple vendor folders by registering namespaces at runtime.

Require "streams/addon-composer": "dev-master", any other dependencies and add the scripts in the composer.json as shown below.


    "require": {
        "streams/addon-composer": "dev-master",
        "league/flysystem" : "dev-master",
        "league/fractal" : "dev-master",
        "league/plates" : "dev-master"
    "scripts": {
        "post-install-cmd": "Streams\\AddonComposer\\Generator::generate",
        "post-update-cmd": "Streams\\AddonComposer\\Generator::generate"

Generated streams.addon.autoload.php

<?php return [
    'psr-4' => [
        'League\\Flysystem\\' => 'league/flysystem/src/',
        'League\\Fractal\\' => 'league/fractal/src',
        'League\\Plates\\' => 'league/plates/src',

The main application can require the streams.addon.autoload.php file and register namespaces with the Composer Classloader. This is an example of what it could look like.

$loader = new Composer\Autoload\ClassLoader;

// Loop through each addon and register the PSR paths

if (is_file($addon['path'] . '/streams.addon.autoload.php')) {
    $autoload = require $addon['path'] . '/streams.addon.autoload.php';

    if (isset($autoload['psr-0'])) {
        foreach ($autoload['psr-0'] as $namespace => $src) {
            $loader->add($namespace, $vendorFolder.$src));

    if (isset($autoload['psr-4'])) {
        foreach ($autoload['psr-4'] as $namespace => $src) {
            $loader->addPsr4($namespace, $vendorFolder.$src));

// Register
