海外TECH	DEV Community	Domain Driven Design Aggregates in Laravel	https://dev.to/bdelespierre/domain-driven-design-aggregates-in-laravel-5ei8	Domain Driven Design Aggregates in LaravelLately I ve been focusing on finding ways to bring Laravel and Domain Driven Design closer together Because I love Laravel but its architecture sucks So today we re going to look at how to implement aggregates using Laravel amp Eloquent Let s get started What IS an aggregate A DDD aggregate is a cluster of domain objects that can be treated as a single unit An example may be an order and its line items these will be separate objects but it s useful to treat the order together with its line items as a single aggregate ーMartin FowlerSo an aggregate is a bag of domain objects that represents something meaningful Let s consider Fowler s order example namespace Domain Model use App Models Order use App Models LineItem class OrderAggregate private Order root var LineItem private array lineItems public function construct Order root array lineItems this gt root root this gt lineItems lineItems public function getRoot Order return this gt order return LineItem public function getLineItems array return this gt lineItems In this aggregate the domain objects are our Eloquent models Order and LineItem It also embodies the following business rule An order consists of an identifier a creation date and zero or more line items That business rule is sometimes referred to as an invariant What can we put in an aggregate An aggregate will have one of its component objects be the aggregate root Any references from outside the aggregate should only go to the aggregate root The root can thus ensure the integrity of the aggregate as a whole ーMartin FowlerBeyond that they may contain EntitiesCollections Lists Sets etc Value objectsValue typed properties integers strings booleans etc You may think of it as a document holding ALL the data necessary to a given transaction or use case Tip Eloquent makes it easy to implement lazy loading in your aggregates In the above example we could restructure the getLineItems method so that it loads when it s used public function getLineItems array return this gt getRoot gt items gt get gt toArray Can they have commands Yes And they should You are not supposed to do car gt getEngine gt start But rather car gt start Forcing the exposure of aggregate s internal structure is bad design How do I persist retrieve them You re going to use the Repository Pattern namespace App Repositories class OrderRepository public function find int id OrderAggregate orderEntity Order with items gt findOrFail id return new OrderAggregate orderEntity orderEntity gt items gt toArray public function store OrderAggregate order void DB transaction function use order order gt getRoot gt save foreach order gt getLineItems as item item gt order gt associate order gt getRoot gt save Rules for making your aggregates pretty From the awesome article series by Vaughn Vernon Rule Keep them small It is tempting to cram one giant aggregate with anything every use case present and future might need But it s a terrible design You re going to run into performances and concurrency issues when several people are working on the same aggregate at the same time It s better to have several representations of order depending on the broader context than one For instance an order from a cart display page s point of view is not the same as from a billing system If we are going to design small aggregates what does “small mean The extreme would be an aggregate with only its globally unique identity and one additional attribute which is not what s being recommended Rather limit the aggregate to just the root entity and a minimal number of attributes and or value typed properties The correct minimum is the ones necessary and no more Smaller aggregates not only perform and scale better they are also biased toward transactional success meaning that conflicts preventing an update are rare This makes a system more usable ーVaughn VernonRule Model true invariants in consistency boundaries It sounds barbaric but it s pretty simple it means that within a single transaction there is no way one could break the aggregate consistency its compliance to business rules In other words it should be impossible to create a bugged version of an aggregate from calling its methods One implication of this rule is that a transaction should only commit a single aggregate since it s not possible by design to guarantee the consistency of several aggregates at once A properly designed aggregate is one that can be modified in any way required by the business with its invariants completely consistent within a single transaction And a properly designed bounded context modifies only one aggregate instance per transaction in all cases What is more we cannot correctly reason on aggregate design without applying transactional analysis Limiting the modification of one aggregate instance per transaction may sound overly strict However it is a rule of thumb and should be the goal in most cases It addresses the very reason to use aggregates ーVaughn VernonRule Don t Trust Every Use Case Don t blindly assemble your aggregates based on what the use case specification dictates They may contain elements that contradict the existing model or force you into committing several aggregates in a single transaction or worse to model a giant aggregate that fits in a single transaction Apply your judgment here and keep in mind that sometimes the business goal can be achieved using eventual consistency The team should critically examine the use cases and challenge their assumptions especially when following them as written would lead to unwieldy designs The team may have to rewrite the use case or at least re imagine it if they face an uncooperative business analyst The new use case would specify eventual consistency and the acceptable update delay ーVaughn Vernon ConclusionMurphy s law states Anything that can possibly go wrong does Properly designed aggregates guarantees that within its boundaries nothing can go wrong well if you write them according to the rules above of course You can say goodbye to those ifs laying around in your code handling those cases that are not supposed to happen but happen anyway Don t allow your model to grow beyond your control Stop using raw data POPOs and unguarded models whose state is uncertain everywhere in your Laravel application Use aggregates instead and connect your model to the actual business your app is supposed to carry Thanks for readingI hope you enjoyed reading this article If so please leave a ️or a and consider subscribing I write posts on PHP architecture and Laravel on a monthly
