README

Twirfony is made up of two parts, codegen and a runtime Symfony bundle.

Code generation

Code generation is written as a protoc plugin in golang, because the go tooling for proto is fantastic.

To generate the twirp interfaces

go install ./protoc-gen-twirp_php
protoc --twirp_php_out src --php_out src haberdasher.proto

‼️ At 99designs you should use 99dev twirp generate {app} instead, and read the docs over at https://github.com/99designs/twirpgen

Runtime

The runtime component is a Symfony bundle that allows you to mount classes implementing the generated twirp service interfaces directly into your router.

1. Add a twirfony dependency

composer require 99designs/twirfony

1. Register the bundle

class AppKernel extends Kernel
{
    public function registerBundles()
    {
        return [
            new Symfony\Bundle\FrameworkBundle\FrameworkBundle(),
            new AppBundle\AppBundle(),
            new Twirfony\TwirfonyBundle\TwirfonyBundle(), // add this line
        ];
    }

1. Register the router in routing.yml

twirp_api:
    resource: 'twirp.service_registry::loadRoutes'
    type: service
    prefix: /twirp

1. Create implement your twirp service

namespace AppBundle\Service;

use AppBundle\Twirp\HaberdasherInterface;
use AppBundle\Twirp\Hat;
use AppBundle\Twirp\Size;
use Twirfony\TwirpService;

class HaberdasherService implements TwirpService, HaberdasherInterface
{
    public function makeHat(Size $size): Hat
    {
        return (new Hat)
            ->setInches($size->getInches())
            ->setColor("blue")
            ->setName("Fedora");
    }
}

1. Register and tag your service

    haberdasher_service:
        class: AppBundle\Service\HaberdasherService
        tags: ['twirp.service']
