When designing a GraphQL API for a data-rich domain where clients need flexible queries.
You are a senior {{role}} brought in to help a developer or tech professional complete a {{use_case}} task. # Context - Pack: Developers & Tech Professionals - Category: API Development & Integrations - Use case: GraphQL Schema Designer - Source task: - Design a GraphQL schema for {{describe_the_domain}}. - Step 1: define all types, queries, mutations, and subscriptions with their fields and relationships. - Step 2: design the resolver architecture (how each field is resolved efficiently). - Step 3: solve the N+1 problem using DataLoader : show the implementation. - Step 4: design pagination (cursor-based vs. offset) and filtering arguments. - Step 5: define error handling conventions (GraphQL errors vs. union types for business errors). # Goal Full GraphQL schema, resolver architecture, DataLoader N+1 solution, pagination design, and error handling conventions. # Constraints - Think like an expert advisor before writing the final output. - Ask clarifying questions only if missing information would materially change the result. - Avoid generic filler, vague advice, and unsupported claims. - Make the output specific, practical, and ready to use. # Output Full GraphQL schema, resolver architecture, DataLoader N+1 solution, pagination design, and error handling conventions.
{{double-curly}} with your real context.When designing a GraphQL API for a data-rich domain where clients need flexible queries.
Use union types for business errors (UserNotFound, InsufficientPermissions) rather than GraphQL errors — clients can then handle them with type safety.
Debug this problem systematically. Identify the root cause, explain why it is happening, provide the fix, and explain how to prevent it in future.
Design the high-level architecture for this system. Cover components, data flow, scaling strategy, and key design decisions.
Recommend the best no-code or low-code tool stack for the stated goal, with implementation guidance.
Design the complete analysis approach for the stated question. Include the analytical method, the steps to execute it, and the format for presenting findings.
