README

Effect/fiber async bridge for PapiAI, built on phunkie/effect and phunkie/streams.

Long-running capabilities such as video generation (Google Veo, OpenAI Sora) can take minutes. This package lets you describe those jobs as pure IO effects, fork them into background fibers, and await the result later — without Symfony Messenger or any external queue.

Install

composer require papi-ai/effect

Requires papi-ai/papi-core ^0.10 and a video-capable provider (e.g. papi-ai/google or papi-ai/openai).

Usage

use PapiAI\Google\GoogleProvider;
use PapiAI\Effect\EffectVideo;

$effect = new EffectVideo(new GoogleProvider($apiKey));

// Describe the work as a lazy IO (nothing runs yet)
$io = $effect->generateVideoIO('a cat surfing a giant wave', ['durationSeconds' => 8]);

// Fork into a background fiber and carry on
$handle = $effect->generateVideoAsync('a cat surfing a giant wave', ['durationSeconds' => 8]);
// ... do other work ...
$video = $handle->await();      // VideoResponse
$video->save('surf.mp4');

Compose the effects with map() / flatMap(), or run them synchronously with unsafeRun().

Progress as a stream

$jobId = $effect->startVideoIO('a neon city at night')->unsafeRun();

foreach ($effect->progressStream($jobId)->toArray() as $status) {
    echo $status->status, "\n"; // running, running, ... completed
}

API

EffectVideo wraps any VideoProviderInterface:

Method	Returns	Notes
generateVideoIO($prompt, $options)	IO<VideoResponse>	blocking generation as a lazy effect
startVideoIO($prompt, $options)	IO<string>	submit, produce a job id
videoStatusIO($jobId)	IO<JobStatus>	poll status
fetchVideoIO($jobId)	IO<VideoResponse>	fetch a completed job
generateVideoAsync($prompt, $options, $context?)	AsyncHandle<VideoResponse>	fork into a fiber; await() later
progressStream($jobId, $maxPolls = 60)	Stream<JobStatus>	observed statuses until terminal
