PHP Composer - set vendor directory

Question

I'm having trouble configuring the vendor path for a Yii2 application. I am adding a couple of lines to the composer.json file I get from the Yii2 basic app template. All I want to do is change the location of my vendor assets.

Below are the changes I have made to the files but I get this error:

The file or directory to be published does not exist: /path/to/app/vendor/bower/jquery/dist

But I'm expecting that particular asset to be published to:

/path/to/vendors/bower/jquery/dist

No matter what I do, I still get that error message. I suspect it's a Yii2 issue and not a composer issue but I'm not sure. Anyone got any ideas? Thanks in advance.

Files...

index.php

// comment out the following two lines when deployed to production
defined('YII_DEBUG') or define('YII_DEBUG', true);
defined('YII_ENV') or define('YII_ENV', 'dev');

require('/path/to/vendors/autoload.php');
require('/path/to/vendors/yiisoft/yii2/Yii.php');

$config = require(__DIR__ . '/../config/web.php');

(new yii\web\Application($config))->run();

composer.json

Turns out there's a there's a simple solution: If you want to change the location of your vendor assets then you must follow these simple steps:

1. include the composer-asset-plugin in your composer.json file

   "require": {
       "fxp/composer-asset-plugin": "*"
   }
   

2. include the composer-asset-plugin directive in your extra config. in your composer.json file:

   "extra": {
   "asset-installer-paths": {
           "npm-asset-library": "../../path/to/vendors/npm",
           "bower-asset-library": "../../path/to/vendors/bower"
       }
   }
   

3. add the vendor location to the config section in your composer.json file:

   "config": {
       "vendor-dir": "../../path/to/vendors"
   }
   

4. update web/index.php to point to the new vendor location:

   require(__DIR__ . '/../../../path/to/vendors/autoload.php');
   require(__DIR__ . '/../../../path/to/vendors/yiisoft/yii2/Yii.php');
   

5. include a vendorPath definition in your config/web.php:

   'vendorPath' => '../../../path/to/vendors',
   

That should work with the vanilla Yii2 basic template.
