README

Lightweight, enterprise-ready pipeline workflow engine for Laravel Supports sequential, parallel, and flow-based execution with debug timeline, retries, timeouts, and queued parallelism.

📦 Installation

Install via Composer:

composer require mr-rijal/laravel-pipeline

Laravel auto-discovers the service provider. No manual registration required.

🛠️ Features

Sequential, parallel, and flow pipelines
Debug timeline with per-step execution metrics
Retry failed steps with configurable attempts
Step timeout support
Parallel execution with optional queue (Redis/Horizon)
Shared LaravelPipelineContext for passing data between steps
Works with Closures or classes implementing handle(LaravelPipelineContext $ctx)
PHPUnit + Testbench ready
Lightweight, production-grade performance

🔧 Usage

1️⃣ Basic Sequential Steps

use MrRijal\LaravelPipeline\Facades\LaravelPipeline;
use MrRijal\LaravelPipeline\DTO\LaravelPipelineContext;

LaravelPipeline::steps([
    fn (LaravelPipelineContext $ctx) => $ctx->set('foo', 'bar'),
    fn (LaravelPipelineContext $ctx) => $ctx->get('foo'), // returns 'bar'
])->run();

2️⃣ Flow (Continue on Fail)

$results = LaravelPipeline::flow([
    fn() => true,
    fn() => false, // continue even if fails
    fn() => true
]);

3️⃣ Parallel (Run All at Once)

$results = LaravelPipeline::parallel([
    StepOne::class,
    StepTwo::class,
]);

🧰 Advanced Features

Debug Timeline

$pipeline = LaravelPipeline::steps([
    StepOne::class,
    StepTwo::class,
])->with(['user_id' => 5]);

$pipeline->run(); // or wrap in try/catch if steps may throw
$results = $pipeline->getResults();

foreach ($results as $step) {
    echo "{$step->name}: " . ($step->success ? '✔' : '✘') . " ({$step->time}ms)\n";
}

Output Example:

StepOne: ✔ (0.12ms)
StepTwo: ✘ (0.21ms) - Exception message if failed

Retry & Timeout

Retry and timeout are currently supported via the runStep() method when building custom pipelines; a more convenient array format [Step::class, 'retry' => 3, 'timeout' => 500] is planned for a future release. See docs for details.

Queued Parallel Execution

LaravelPipeline::parallel([
    StepOne::class,
    StepTwo::class
], queue: true); // Dispatches steps to Laravel queue

Works with Laravel Redis queues or Horizon
Steps executed concurrently without blocking main thread

Shared Pipeline Context

LaravelPipelineContext allows passing data between steps:

LaravelPipeline::steps([
    fn (LaravelPipelineContext $ctx) => $ctx->set('user_id', 123),
    fn (LaravelPipelineContext $ctx) => $ctx->get('user_id'), // 123
])->run();

⚡ Benchmark

vendor/bin/phpunit --filter BenchmarkTest

Typical performance (3-step pipeline):

Sequential: < 10ms (micro-benchmark)
Memory usage: negligible
Parallel queued execution depends on queue worker speed

💡 Step Types

Closure

fn (LaravelPipelineContext $ctx) => true

Class with handle() (class name or instance)

class StepOne
{
    public function handle(LaravelPipelineContext $ctx): bool
    {
        return true;
    }
}

Boolean literal

true // simple pass/fail (e.g. in flow())

🔧 Testing

Run PHPUnit tests:

vendor/bin/phpunit

Includes:

Sequential / flow / parallel tests
Micro-benchmark tests

📝 Notes

Make sure queue workers are running when using parallel(queue: true)
Use getResults() for detailed debugging or logging
Step names are auto-detected from class name or “Closure”
