Dependencies

This package is intentionally small, so understanding its dependencies is the best way to understand the package itself.

Direct Runtime Dependencies

Package	Kind	Why it exists here
PHP	Runtime	The package targets PHP 8.3 and newer.
fast-forward/container	FastForward runtime dependency	Supplies container integration and the factory helper classes used by the provider.
psr/http-client	Standard interface package	Defines `Psr\Http\Client\ClientInterface` .
psr/http-factory	Standard interface package	Defines the PSR-17 factory interfaces consumed by `Psr18Client` .
symfony/http-client	Transport implementation	Provides `HttpClient` and `Psr18Client` .

Recommended Companion Packages

These packages are not required by this repository directly, but they are the most common companions in real FastForward applications:

Package	Why you might add it
fast-forward/http-factory	Registers the PSR-17 factory services required to build `Psr\Http\Client\ClientInterface` successfully.
fast-forward/http	Bundles the FastForward HTTP factory and HTTP client providers for the simplest onboarding path.
fast-forward/http-message	Provides FastForward HTTP message utilities used by the factory layer in the broader FastForward HTTP stack.
nyholm/psr7-server	Used by `fast-forward/http-factory` to provide concrete PSR-17 and server-request support.

Relevant Standards

PSR-18 defines the client contract exposed by this package.
PSR-17 defines the factory interfaces that the registered Psr18Client expects from the container.
PSR-11 defines the container contract most users interact with after registration.

Runtime Note About Symfony

Symfony's HttpClient::create() chooses the best available client at runtime. Depending on your environment, that may be a Curl, Amp, or Native client. This package does not force one transport implementation; it delegates that decision to Symfony.
