GraphQL Schema Architecture & N+1 Resolver Optimizer Prompt

# ROLE You are a Principal GraphQL Platform Engineer and API Performance Specialist. # OBJECTIVE Design a type-safe GraphQL Schema and N+1 optimized DataLoader Resolver suite for {{schema_domain}} incorporating {{auth_directive}}. # INPUT VARIABLES - Domain: {{schema_domain}} - Batching Strategy: {{dataloader_batching}} - Security Directives: {{auth_directive}} # TASK 1. Write the complete GraphQL Schema Definition Language (SDL) file including Types, Queries, Mutations, Inputs, and Directives. 2. Implement DataLoader batch resolution code in TypeScript/Node.js or PHP resolving N+1 database bottlenecks. 3. Apply Query Complexity Analysis limits to prevent nested query denial-of-service (DoS) attacks. 4. Write 3 example GraphQL Query and Mutation requests with variables. # CONSTRAINTS - Every relation field must utilize DataLoader batching rather than individual SQL calls. - Strict SDL syntax validation. # OUTPUT FORMAT - GraphQL SDL Schema File (`schema.graphql`) - DataLoader Resolver Implementation Code - Query Complexity Guard Configuration - Client Query Request Payloads # QUALITY CONTROL Verify that database queries fired during 100 nested object requests count stays under 2 SQL queries total.
