graphqlCut GraphQL Payloads with Persisted Queries in Apollo Client and Server
Learn how Apollo’s persisted‑queries feature shrinks request size, hardens security, and what you need to keep in sync. A step‑by‑step guide, example config, and trade‑offs are included.
apollographqlImplementing GraphQL Subscriptions with Apollo Server and WebSocket in Node.js
Learn how to add real‑time GraphQL subscriptions to a Node.js app using Apollo Server, graphql‑ws, and a shared PubSub engine. The guide covers schema, server setup, authentication, scaling, and troubleshooting steps.
nodejsUsing GraphQL Persisted Queries to Shrink Request Payloads
Learn how GraphQL persisted queries replace large query bodies with short hashes, reducing bandwidth and boosting HTTP caching, with a concrete Apollo Server/Client setup and verification steps.
Why Persisted Queries Are a Practical Win for GraphQL APIs
Persisted queries replace full GraphQL strings with tiny hashes, cutting payload size and locking down the API to a pre‑approved whitelist. This post shows a minimal Apollo Server + Client setup, the operational trade‑offs, and a verification checklist you can run today.
Persisted Queries in GraphQL: The Hardening Step Most Teams Skip
Persisted queries let a GraphQL server execute only pre-approved operations by hash. Here's how the APQ exchange works, when to move to a strict allow-list, and how to verify it.

Learn how DataLoader batches resolver calls to eliminate the N+1 query problem in GraphQL, with a concrete Node.js example, trade‑offs, and a verification checklist.
Solving the N+1 Query Problem in Apollo Server with DataLoaders
Discover how Apollo Server’s DataLoader solves the N+1 query problem by batching and caching database requests, improving GraphQL API performance.
Does Apollo Server's createTestClient execute custom Express middleware during testing?
When writing integration tests for an Apollo Server schema, the goal is to verify that resolver logic works alongside any custom Express middleware (such as request‑level logging, CORS handling, or rate‑limiting) without relying on production credentials or making real network calls. The createTestClient utility from @apollo/server/testing provides an in‑pro
