So I am currently working on a Composer package with a small library that I want to use with CakePHP projects. My question is, how do I use the class I defined in this package in my controllers?

Running `composer require my_vendor/my_lib` works like a charm and adds the files like `[cake_root]/vendor/my_vendor/my_lib/lib.php`

However, how do I now use this? Slightly related, is this considered a plugin? Do I load it like a plugin?

Thanks in advance!

By default you can access all composer packages automatically.

So I wouldn’t have to do anything?

But at this point I get ‘no class found’ messages when I try `$x = new MyClass()` anywhere.

In your packages you have to specify root namespace that you house (e.g: Himan101) in the composer.json [(see documentation)](https://getcomposer.org/doc/04-schema.md#autoload)

then in the cakephp project

```php
    use Hitman101\MyClass
    $x = new MyClass();

```
