GraphQL over REST Example

This project demonstrates how to implement a GraphQL API layer over an existing REST API using Apollo Server. It uses the JSONPlaceholder API as an example REST endpoint.

Features

• GraphQL server using Apollo Server
• REST API integration using Axios
• Example queries for Users and Posts
• Nested resolvers for related data

Getting Started

1. Install dependencies:

pnpm install

2. Start the development server:

pnpm dev

The GraphQL server will be available at http://localhost:4000

Example Queries

Get all posts with their authors

query {
  posts {
    id
    title
    body
    user {
      id
      name
      email
    }
  }
}

Get a specific user with their posts

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