About

This Claude Skill provides expert GraphQL API design and implementation guidance. It specializes in schema-first design, resolver implementation, DataLoader for N+1 prevention, and federation architecture while following Apollo and Relay best practices. Use it when designing schemas, implementing queries/mutations, setting up pagination, handling errors, or working with GraphQL libraries.

Documentation

GraphQL API Standards

Naming Conventions

Field Naming

  • Boolean: Require is/has/can prefix
  • Date: Require ~At suffix
  • Use consistent terminology throughout the project (unify on either "create" or "add")

Date Format

  • ISO 8601 UTC
  • Use DateTime type

Pagination

Relay Connection Specification

type UserConnection {
  edges: [UserEdge!]!
  pageInfo: PageInfo!
}

type UserEdge {
  node: User!
  cursor: String!
}

type PageInfo {
  hasNextPage: Boolean!
  endCursor: String
}
  • Parameters: first, after

Sorting

  • orderBy: [{ field: "createdAt", order: DESC }]

Type Naming

  • Input: {Verb}{Type}Input
  • Connection: {Type}Connection
  • Edge: {Type}Edge

Input

  • Separate creation and modification (required for creation, optional for modification)
  • Avoid nesting - IDs only

Errors

extensions (default)

  • code, field in errors[].extensions

Union (type safety)

  • User | ValidationError

N+1

  • DataLoader is mandatory

Documentation

  • """description""" is required
  • Explicitly state Input constraints

Deprecation

  • @deprecated(reason: "...")
  • Never delete types
