How does the Illuminate Pipeline pattern work and how do you use it for complex multi-step workflows?
❓ Interview Prompt: Explain IlluminatePipelinePipeline, sending passable objects through pipe classes, and constructing multi-step business processing flows.
The Illuminate Pipeline pattern passes an initial data object through a series of sequential 'pipe' classes, where each pipe modifies the payload or executes logic before passing it to the next pipe.
Use Cases:
Ideal for complex multi-step checkout processing, order verification, data ingestion pipelines, and HTTP middleware execution!
Code Implementation Example
php
<?php
use IlluminateSupportFacadesPipeline;
use AppPipesVerifyStock;
use AppPipesApplyDiscount;
use AppPipesProcessPayment;
$order = Pipeline::send($initialOrder)
->through([
VerifyStock::class,
ApplyDiscount::class,
ProcessPayment::class,
])
->then(fn ($order) => $order);💡Executing multi-step checkout pipeline using Illuminate Pipeline facade.
🎯 Interview Key Takeaway
Use the Illuminate Pipeline pattern to process complex multi-step business workflows through sequential pipe classes.
