README

A PHPStan extension that disallows using classes from transitive dependencies.

Installation

composer require --dev spencermalone/phpstan-no-transitive-use

Usage

The extension will automatically be loaded when you run PHPStan. It will check all use statements in your code and report an error if you're trying to use a class from a transitive dependency.

For example, if your project depends on package A which depends on package B, and you try to use a class from package B directly, PHPStan will report an error.

Configuration

If you do not use phpstan/extension-installer, you need to add:

includes:
	- vendor/spencermalone/phpstan-no-transitive-use/extension.neon

to your phpstan.neon

No additional configuration is needed if you use phpstan/extension-installer.

The extension automatically reads your composer.json to determine which dependencies are primary (directly required) and which are transitive.

Example

// This will cause an error if 'vendor/transitive/package' is not in your composer.json
use Transitive\Package\SomeClass;
