GraphQL Query Too Deep - Nested Query Recursion Attack
GraphQL queries with deep nesting cause timeouts or excessive server load. User can request deeply nested data causing exponential database queries.
Server becomes unresponsive to legitimate queries.
Error Messages You Might See
Query exceeds maximum depth
Query too complex - execution timeout
Maximum query cost exceeded
Recursion depth exceeded
Common Causes
- No query depth limit - unlimited nesting allowed
- No complexity calculation
- Circular references in schema allowing infinite recursion
- No timeout on query execution
- Database N+1 problem triggered by deep nesting
How to Fix It
Add depth limit: graphql-depth-limit middleware, max depth 7
Add complexity limit: estimate cost per field, reject if over budget
Break circular references: use aliases or limit nesting depth
Set query timeout: 10-30 seconds max execution time
Use data loader to prevent N+1 queries

Caio Rodrigues
I'm a full-stack developer focused on building practical and scalable web applications. My main experience is with **React, TypeScript, and modern frontend architectures**, where I prioritize clean code, component reusability, and maintainable project structures.
I have strong experience working with **dynamic forms, state management (Redux / React Hook Form), and complex data-driven interfaces**. I enjoy solving real-world problems by turning ideas into reliable software that companies can actually use in their daily operations.
Beyond coding, I care about **software quality and architecture**, following best practices for componentization, code organization, and performance optimization.
I'm also comfortable working across the stack when needed, integrating APIs, handling business logic, and helping transform prototypes into production-ready systems.
My goal is always to deliver solutions that are **simple, efficient, and genuinely useful for the people using them.**

I am a technologist and product builder dedicated to creating high-impact solutions at the intersection of AI and specialized markets. Currently, I am focused on PropScan (EstateGuard), an AI-driven SaaS platform tailored for the Japanese real estate industry, and exploring the potential of Archify.
As an INFJ-T, I approach development with a "systems-thinking" mindset—balancing technical precision with a deep understanding of user needs. I particularly enjoy the challenge of architecting Vertical AI SaaS and optimizing Small Language Models (SLMs) to solve specific, real-world business problems. Whether I'm in a CTO-level leadership role or hands-on with the code, I thrive on building tools that turn complex data into actionable value.

You don't need to be technical. Just describe what's wrong and a verified developer will handle the rest.
Get HelpFrequently Asked Questions
What's a reasonable query depth limit?
7-10 is good balance. Most legitimate queries are 3-5 levels deep
How do I implement depth limit?
Use graphql-depth-limit package: depthLimit(10) as middleware
What's query complexity?
Estimate cost: simple field = 1, list = 10. Reject queries exceeding total budget (e.g., 1000)
