This package provides a proxy generator for [Symfony's dependency injection component](https://symfony.com/doc/current/components/dependency_injection.html) that generates super tiny, super simple proxies, especially when [compared to Symfony's default implementation](https://github.com/olvlvl/symfony-dependency-injection-proxy/wiki/Comparison). Here are some differences:

- Can proxy `final` classes.
- Can only proxy classes with interfaces.
- The generated proxies are self-contained.
- The package is ~10Kb and doesn't have dependencies.
- The package can be removed once the proxies have been generated.

If you're not familiar with proxy services, better have a look at [Symfony's documentation](https://symfony.com/doc/current/service_container/lazy_services.html)before going any further.

#### Installation

[](#installation)

```
composer require olvlvl/symfony-dependency-injection-proxy
```

How it works
------------

[](#how-it-works)

The generator works with the following assumptions: the service we want to proxy implements an interface, and services using that service expect that interface, following the [dependency inversion principle](https://en.wikipedia.org/wiki/Dependency_inversion_principle). Now, consider the following code, where an `ExceptionHandler` service requires a logger implementing `LoggerInterface`:

```
