Multipart uploads in GraphQL are technically possible, but in practice they cause more problems than they solve. Anyone uploading files through GraphQL ends up fighting proxies, body size limits, missing caching, and resolvers that are hard to test. This article explains where the real limits lie and how presigned URLs solve the problem more elegantly.
How to model filter and sort arguments as clean input types, implement operator patterns for different data types, use Magento's filter conventions, and choose the right pagination strategy for each use case.
The category page is the most important performance hotspot in almost every Magento shop. Too many fields, resolver chains that run too deep, and missing caching strategies make it slower than it needs to be. The lever is in the query, not the server.
Magento GraphQL is not a simple API add-on, but a modular system that merges schema files from every active module, builds resolver chains and provides context objects for store, locale and authentication. Anyone who understands this system can build their own queries and extend existing resolvers with precision.
Anyone who changes a GraphQL schema without knowing the existing clients risks silent breakage in the frontend. Additive evolution, structured deprecations, and automated schema diffs with GraphQL Inspector make schema changes predictable instead of random.
A GraphQL API that works in development mode is not yet a production-ready API. Performance traps, security gaps and missing observability only surface under load, exactly when there is little room to react. This checklist closes those gaps before they become a problem.
GraphQL APIs without systematic tests are fragile: every schema change can silently break frontends. Query tests, snapshots, and contract tests together form a testing layer that catches regressions early and keeps frontend contracts stable over the long run.
When a Magento page fails to load or shows wrong data, the problem often lies in a GraphQL query, but where exactly? Browser DevTools, Magento logs and dedicated GraphQL clients form the complete debugging stack.
GraphQL subscriptions enable realtime communication over persistent connections, but they come with substantial scaling and infrastructure requirements. This article explains the concept, the transport options, the design decisions, and when subscriptions are actually the right choice.
The right debugging tool for GraphQL is not always the best known one. Whether browser-embedded, desktop app, or API client, each tool has its place in the diagnostic workflow. Knowing each tool's strengths means debugging queries, auth issues, and resolver errors more efficiently.
