Stop Context-Switching: Streamline Enterprise GraphQL Development

Your team is building a GraphQL API that needs to scale across multiple services, handle enterprise security requirements, and maintain performance under load. You're tired of hunting through scattered documentation, inconsistent patterns, and debugging production issues that could have been prevented.

The Enterprise GraphQL Reality Check

Building GraphQL APIs in enterprise environments isn't just about writing resolvers. You're dealing with:

Federation complexity across multiple teams and services
Performance bottlenecks from N+1 queries and unoptimized data fetching
Security vulnerabilities from inadequate input validation and authorization
Debugging nightmares without proper observability and error handling
Schema chaos when multiple developers work without consistent patterns
Production incidents from missing query complexity limits and monitoring

The result? Your team spends more time fighting the toolchain than building features.

Your Complete GraphQL Development Framework

These Cursor Rules transform your GraphQL development by providing battle-tested patterns for every aspect of enterprise API development. From schema design to production monitoring, you get consistent, secure, performant code every time.

What you get:

Schema-first TypeScript development with automatic type generation
Enterprise-grade security with authentication, authorization, and input validation
Performance optimization through DataLoader batching and query complexity limits
Production-ready observability with tracing, metrics, and structured logging
Federation-ready architecture for microservices environments

Key Benefits That Transform Your Workflow

Eliminate Security Vulnerabilities Before Production

// Before: Manual security checks scattered everywhere
const user = await getUserById(args.id); // No validation, no auth

// After: Security built into every resolver
export const user: QueryResolvers<Context>["user"] = async (_parent, { id }, ctx) => {
  ctx.auth.assertLoggedIn(); // Automatic auth check
  if (!isUUID(id)) throw ctx.errors.badUserInput("Invalid ID format");
  return ctx.loaders.user.load(id);
};

Stop N+1 Queries From Crushing Performance

// Automatic DataLoader batching prevents database overload
const users = await Promise.all(
  postIds.map(id => ctx.loaders.user.load(id)) // Batched automatically
);

Debug Production Issues in Minutes, Not Hours

// Rich error context with correlation IDs and structured logging
{
  "message": "User not found",
  "extensions": {
    "code": "USER_NOT_FOUND",
    "timestamp": "2024-01-15T10:30:00Z",
    "requestId": "req_123abc",
    "userId": "user_456def"
  }
}

Real Developer Workflows: Before vs After

Scenario 1: Adding New GraphQL Endpoints

Before: 30+ minutes of boilerplate setup

// Manual type definitions, resolver setup, validation logic
// Inconsistent error handling across team members
// Missing security checks discovered in code review

After: 5 minutes with consistent patterns

// Auto-generated types from schema
// Built-in validation and security
// Standardized error handling
export const createProduct: MutationResolvers<Context>["createProduct"] = 
  async (_parent, { input }, ctx) => {
    ctx.auth.assertRole("ADMIN");
    const product = await ctx.services.product.create(input);
    return product;
  };

Scenario 2: Debugging Performance Issues

Before: Hours of investigation with limited visibility

Manually adding logging to suspect resolvers
Guessing at query complexity issues
No insight into database query patterns

After: Immediate visibility with built-in observability

// Automatic tracing and metrics
// Query complexity limits prevent abuse
// DataLoader batching visible in logs
// OpenTelemetry integration shows full request flow

Scenario 3: Schema Evolution Across Teams

Before: Breaking changes and coordination nightmares

Manual schema synchronization
Inconsistent deprecation practices
Federation conflicts discovered at runtime

After: Controlled evolution with federation support

// Schema checks in CI/CD pipeline
// Automatic deprecation workflows
// Federation-ready entity definitions with @key directives

Implementation Guide

Step 1: Install and Configure

# Add to your .cursorrules file
curl -o .cursorrules https://cursor-rules.com/enterprise-graphql-rules

# Install required dependencies
npm install @apollo/server @apollo/federation graphql dataloader
npm install -D @types/node typescript graphql-codegen

Step 2: Set Up Your Project Structure

src/
  modules/
    user/
      schema.graphql    # Domain-specific schema
      resolvers.ts      # Type-safe resolvers
      dataloaders.ts    # Batching logic
    product/
      ...
  lib/
    errors.ts          # Centralized error handling  
    auth.ts           # Authentication logic
    context.ts        # Request context setup

Step 3: Write Your First Module

// src/modules/user/schema.graphql
extend type Query {
  user(id: ID!): User
}

type User @key(fields: "id") {
  id: ID!
  email: String!
  profile: UserProfile
}

// src/modules/user/resolvers.ts
export const resolvers: Resolvers<Context> = {
  Query: {
    user: async (_parent, { id }, ctx) => {
      ctx.auth.assertLoggedIn();
      return ctx.loaders.user.load(id);
    }
  }
};

Step 4: Enable Production Features

// Built-in query complexity limits
const server = new ApolloServer({
  plugins: [
    ApolloServerPluginUsageReporting(),
    queryComplexityPlugin({ maximumComplexity: 1000 })
  ]
});
