README

The framework-agnostic core of BabelQueue for PHP — the canonical polyglot queue envelope codec, contracts and dead-letter helpers. Framework adapters (babelqueue/laravel, babelqueue/symfony, …) are built on top of this.

You usually don't install this directly — you install an adapter:

composer require babelqueue/laravel    # Laravel
composer require babelqueue/symfony    # Symfony (Messenger)

…and the adapter pulls this core in. Install it directly only for a framework-less PHP app, or to build a new adapter.

composer require babelqueue/php-sdk

What's in here

The contract this core implements — the canonical envelope, URN scheme, broker bindings and versioning policy — is documented at babelqueue.com. The golden conformance fixtures live in tests/fixtures/ — every PHP package must round-trip them.

Framework-less use

Produce the canonical envelope from a plain PHP app and let any other SDK consume it. The reference transports keep the core dependency-free — install only the broker client you use:

composer require predis/predis              # for RedisTransport
composer require php-amqplib/php-amqplib    # for AmqpTransport

use BabelQueue\Codec\EnvelopeCodec;
use BabelQueue\Transport\RedisTransport;
use BabelQueue\Validation\EnvelopeValidator;

// Produce — a Go/Python/Node consumer reads the identical envelope off "orders".
$transport = new RedisTransport(new Predis\Client('redis://localhost:6379'));
$transport->publish(EnvelopeCodec::encode(EnvelopeCodec::fromJob($job, 'orders')), 'orders');

// Consume (your own loop) — validate before dispatch, quarantine the unknown.
$envelope = EnvelopeCodec::decode($rawBody);
if ($reason = EnvelopeValidator::check($envelope)) {
    // $reason === 'unsupported_schema_version' → dead-letter, don't drop.
    return;
}

phpredis (ext-redis) users can implement the one-method Transport directly — it is just an rpush.

Design

This core is the contract runtime, not a worker. It does not own a broker loop or retry — adapters bind to each framework's native queue (Laravel's drop-in driver, Symfony Messenger) and reuse that framework's worker/retry.

Testing

composer install
vendor/bin/phpunit
