Since Magento 2.4 Elasticsearch is the only supported search engine – MySQL Search was removed. For many shops it “just works”, but when a client reports that “the search doesn’t find the right products”, the real work begins. I show how Magento indexes data in ES, how to debug queries, and how to extend the index with custom fields.
PHP 8.0 ma wyjść w listopadzie 2020 i będzie największą zmianą w języku od czasu PHP 7.0. JIT compiler, union types, named arguments, match expression, constructor property promotion – to nie są drobne poprawki. Przeglądam najważniejsze nowości na przykładach i oceniam co realne znaczenie dla codziennego kodu z Magento 2.
Repository is a pattern that separates business logic from the details of data access. Instead of scattering SQL queries or ORM calls throughout the application, you have one class responsible for fetching and saving entities. In Magento 2 Repository is part of Service Contracts – a standard, not an option. I show how to build your own Repository from scratch and why it is worth doing.
When a shop has several thousand products with dozens of attributes in several languages, managing product data directly in Magento becomes a real pain. Akeneo PIM solves this – it centralises product data and delivers it to Magento (and other channels) through an API. I show why you would want a PIM and what the technical integration looks like.
DDEV works great day to day, but what if you need a custom configuration DDEV does not support? Or you want to understand what is happening under the hood? I show how to build a PHP environment from scratch with pure Docker and docker-compose – nginx, PHP-FPM, MySQL and Redis with no intermediate tools.
PHP array is versatile enough that we rarely need other data structures. But a doubly linked list has properties an array does not – inserting and removing elements from the middle in O(1), without shifting the remaining elements. I implement one from scratch in PHP and show when it is worth reaching for.
Magento 2.3 introduced GraphQL as an alternative to the REST API. Where REST requires separate endpoints for each resource, GraphQL lets the client decide what data it needs in a single query. I show how to write a custom resolver and expose data through GraphQL in a Magento 2 module.
PHP 7.4 was released in November 2019. After migrating several Magento 2 modules to the new version I have a clear picture. Typed properties genuinely affect the way you write classes – but they also have pitfalls worth knowing. I show what works great, what surprises you, and what migration looks like in practice.
The new operator in production code is a warning sign. A class that directly instantiates other classes is tightly coupled to them – hard to test, hard to extend. Factory Method delegates the responsibility for object creation to dedicated classes. In Magento 2 factories are everywhere – and generated automatically.
Operations like sending emails, syncing with an ERP, or recalculating indexes do not have to block an HTTP request. Magento 2 has a built-in Message Queue Framework that lets you push such tasks to an asynchronous queue. I show how it works with RabbitMQ and how to write your own publisher and consumer.
