Symfony Turbo: SPA Feel Without a JavaScript Framework

Maxim Mironjuk - January 09, 2026

Single-page-application feel does not require React, Vue or Angular. With Symfony Turbo and Hotwire, users navigate without full-page reloads, form submits update only the relevant page regions, and real-time updates land directly in the DOM via Turbo Streams, all controlled server side.

Maxim Mironjuk - January 05, 2026

The shared kernel pattern solves a problem that appears in almost every Symfony microservice landscape: several services need the same value objects, error codes or event contracts. This article shows how a shared kernel is built as its own versioned Composer package, what belongs inside, what has to stay out, and how contract tests prevent creeping coupling.

Maxim Mironjuk - January 01, 2026

Without preloading, every single Symfony request recompiles the same thousand classes from OPcache bytecode all over again.

Maxim Mironjuk - December 20, 2025

The N+1 problem is the most common performance killer in Symfony projects that use Doctrine ORM. It creeps in silently, often in seemingly harmless template code, and generates hundreds of database queries where a single one would have been enough. With DQL, the QueryBuilder and JOIN FETCH it can be eliminated systematically.

Writing Custom DQL Functions in Doctrine

Maxim Mironjuk - December 05, 2025

When DQL hits its limits because a native SQL function like JSON_EXTRACT or MATCH AGAINST is missing, a custom DQL function is often the cleaner solution than falling back entirely to native queries. Doctrine's FunctionNode API makes exactly that possible.
