GraphQL & Advanced API Design

Quick Start

Basic GraphQL Schema

type User {
  id: ID!
  name: String!
  email: String!
  posts: [Post!]!
}

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

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

type Mutation {
  createUser(name: String!, email: String!): User!
  createPost(title: String!, content: String!): Post!
}

Query Examples

query {
  user(id: "1") {
    name
    email
    posts {
      title
    }
  }
}

Production Code Examples

# Command line examples for quick start
# Replace with language-specific code
echo "Production code examples will be customized per skill"

Real-World Projects

1. Beginner Project (Level: Beginner)

   • Core concepts application
   • Basic requirements
   • Expected duration: 1-2 weeks

2. Intermediate Project (Level: Intermediate)

   • Multiple integrations
   • Advanced concepts
   • Expected duration: 3-4 weeks

3. Advanced Project (Level: Advanced)

   • Production-grade application

Key Topics

• Schema Design: Types, queries, mutations, subscriptions
• Resolvers: Writing efficient resolvers
• DataLoader: Preventing N+1 queries
• Authentication: Securing GraphQL endpoints
• Subscriptions: Real-time data with WebSockets
• Performance: Query cost analysis, rate limiting
• Federation: Apollo Federation for microservices
• Best Practices: Schema conventions, error handling

Best Practices

✅ Design schemas carefully ✅ Use DataLoader for batch queries ✅ Implement proper error handling ✅ Version APIs with fields, not breaking changes ✅ Document with SDL ✅ Implement authentication and authorization ✅ Monitor query performance
