Building GraphQL Server

Overview

Build production-ready GraphQL servers with SDL-first or code-first schema design, efficient resolver implementations with DataLoader batching, real-time subscriptions via WebSocket, and field-level authorization. Support Apollo Server, Yoga, Mercurius, and Strawberry across Node.js and Python runtimes.

Prerequisites

• Node.js 18+ with Apollo Server/Yoga/Mercurius, or Python 3.10+ with Strawberry/Ariadne
• Database with ORM (Prisma, TypeORM, SQLAlchemy) for resolver data sources
• Redis for subscription pub/sub and DataLoader caching (production deployments)
• GraphQL client for testing: GraphiQL, Apollo Studio, or Insomnia
• graphql-codegen for TypeScript type generation from schema (recommended)
