Graphql

This skill handles GraphQL schema definition, queries, mutations, and server setup with detailed resolver patterns. You'll want it when building flexible APIs that need to serve multiple client types without the usual REST overfetching problems, or when you're aggregating microservices behind a single endpoint. The progressive disclosure is well structured: quick start gets you from schema to working Apollo Server in minutes, then the full content covers everything from DataLoaders and subscriptions to TypeScript codegen and federation patterns. It's opinionated toward Apollo but covers the fundamentals that transfer across implementations. The resolver examples and type system sections are thorough enough to be genuinely useful, not just reference material.

GraphQL Skill

Summary

GraphQL is a query language and runtime for APIs that enables clients to request exactly the data they need. It provides a strongly-typed schema, single endpoint architecture, and eliminates over-fetching/under-fetching problems common in REST APIs.

When to Use

Building flexible APIs for multiple client types (web, mobile, IoT)
Complex data requirements with nested relationships
Mobile-first applications needing bandwidth efficiency
Reducing API versioning complexity
Real-time data with subscriptions
Microservices aggregation and federation
Developer experience with strong typing and introspection

Quick Start

1. Define Schema (SDL)

# schema.graphql
type User {
  id: ID!
  name: String!
  email: String!
  posts: [Post!]!
}

type Post {
  id: ID!
  title: String!
  content: String!
  author: User!
  publishedAt: DateTime
}

type Query {
  user(id: ID!): User
  users: [User!]!
  post(id: ID!): Post
}

type Mutation {
  createPost(title: String!, content: String!, authorId: ID!): Post!
  updatePost(id: ID!, title: String, content: String): Post!
  deletePost(id: ID!): Boolean!
}
