Building Mutations in Magento: Input, Service Contract, Response

Maxim Mironjuk - January 11, 2026

A GraphQL mutation is more than a resolver with side effects. Anyone who doesn't model input types in the schema, writes business logic directly into the resolver, or fails to return errors as a structured response ends up with an API that is hard to test, document, and extend.

Writing Your Own GraphQL Resolver in Magento 2 | Query and Mutation

Maxim Mironjuk - January 02, 2026

Custom Magento 2 GraphQL resolvers connect the schema, query logic and service layer. What matters most is clear types, clean resolver classes and an architecture that does not push business logic directly into the resolver.

Implementing Optimistic UI Updates with GraphQL Mutations Correctly

Maxim Mironjuk - December 30, 2025

A like button that only reacts after three hundred milliseconds of network latency feels sluggish, even if the server technically responds fast. Optimistic UI updates solve this perception problem by having GraphQL mutations show the expected result instantly in the interface and only roll back cleanly on failure, instead of making the user wait for every interaction.

Making GraphQL Errors Reproducible: Logging, Tracing, Correlation IDs

Maxim Mironjuk - December 28, 2025

Intermittent GraphQL errors are hard to reproduce because context is missing. Structured logging, request tracing, and correlation IDs make every error traceable, even days after it occurred, even across multiple resolver chains.

GraphQL Authentication: Tokens, Sessions and Field-Level Auth

Maxim Mironjuk - December 25, 2025

Authentication in GraphQL is not a special case, it is part of every resolver that touches user-specific data. Anyone who fails to explicitly model token validation, session context and field-precise access control is building security gaps into the schema before the first query ever reaches production.

CSRF Protection for GraphQL Endpoints: What Differs From REST

Maxim Mironjuk - December 22, 2025

Many REST teams rely on simple content-type checks or the assumption that cross-site requests only ever touch GET requests. GraphQL bundles queries and mutations behind a single POST endpoint, rendering these assumptions worthless. Anyone running a GraphQL API with cookie-based sessions needs explicit CSRF protection that accounts for the specifics of that single endpoint.

PostGraphile: Instant GraphQL API from Your Database Schema

Maxim Mironjuk - December 19, 2025

PostGraphile reads a PostgreSQL schema and produces a complete, type-safe GraphQL API without writing a single resolver by hand. Tables, foreign keys, constraints and row-level security policies become fields, relationships and permissions directly, making classic boilerplate between database and API practically disappear.

Lighthouse GraphQL for Laravel: A Hands-On Start

Maxim Mironjuk - December 17, 2025

Lighthouse wires GraphQL schemas directly onto Eloquent models, without requiring a dedicated resolver for every field. Instead of building PHP classes, SDL directives like @hasMany, @paginate and @guard describe the entire connection to the database, relationships and middleware. Anyone already familiar with Laravel conventions gets productive with Lighthouse quickly.

Offline-First GraphQL with Apollo Client Cache Persistence

Maxim Mironjuk - December 17, 2025

A network outage should never mean a dead app. With cache persistence, a mutation queue for pending changes, and thoughtful conflict resolution, a GraphQL application can be built so users keep reading, keep working, and keep making changes while the connection is waited on in the background.

GraphQL and Server-Sent Events as an Alternative to Subscriptions

Maxim Mironjuk - December 17, 2025

WebSocket-based GraphQL Subscriptions bring bidirectional communication that most realtime use cases don't even need. Server-Sent Events, as a GraphQL Subscriptions alternative, offer a simpler, HTTP-native path for unidirectional updates, without a custom protocol, a custom reconnect mechanism, or extra infrastructure.
