GraphQL lets frontend teams request only the data they need. This freedom brings new responsibilities.

Follow these steps for a stable production setup:

• Build a clear schema. Your schema is a contract. Use clear names for types and fields. Add comments. Simple schemas are easy to use.
• Fix the N+1 problem. Resolvers run for every field. One query for 100 items often triggers 101 database calls. Use DataLoader to batch requests.
• Limit query depth and complexity. Stop users from sending huge queries. Set a cost for each query. Reject queries over your limit.
• Put authorization in your resolvers. Users need specific permissions for specific fields. This ensures they see only allowed data.
• Use code generation. Tools like GraphQL Code Generator sync your server and client. This turns runtime errors into compile-time errors.
• Use polling first for real-time updates. Subscriptions over WebSockets are hard to scale. Move to subscriptions only when you need them.
• Track each resolver separately. Find the exact bottleneck. Use timing metrics and trace IDs. This makes debugging scientific.
