Dependencies

Runtime dependencies

Direct runtime dependencies are intentionally small:

Dependency Category Notes
php ^8.3 Platform Required runtime version
psr/log ^3.0 Composer package Optional logger integration through LoggerInterface

Runtime capability dependencies

The package also depends on runtime capabilities rather than Composer packages:

  • pcntl_async_signals
  • pcntl_fork
  • pcntl_signal
  • pcntl_waitpid
  • posix_getpid
  • posix_kill
  • stream_socket_pair
  • stream_select

Development dependencies

Direct development dependency:

Dependency Role
fast-forward/dev-tools Aggregates development tooling, CI support, static analysis, formatting, and documentation helpers

  • PSR-11 integration is application-defined rather than bundled.
  • Logger implementations such as Monolog are optional and can be added by the host application.
