Mock GraphQL Server

This project is a simple mock GraphQL server built with Node.js and Apollo Server. It allows you to experiment with GraphQL queries, mutations, and advanced concepts like fragments, inline fragments, and unions. The server includes a mock dataset of books and authors, making it easy to test GraphQL functionalities.

Getting Started

Prerequisites

• Node.js: Make sure you have Node.js installed on your computer. You can download it from Node.js Official Site.

Installation

1. Clone the Repository:

   git clone git@github.com:MohiFayden/mock-graphql-server.git
   cd mock-graphql-server

2. Install Dependencies:

   npm install

Running the Server

To start the server, run:

node index.js

By default, the server will run on http://localhost:4000.

Accessing the GraphQL Playground

Once the server is running, you can open the GraphQL Playground by navigating to:

http://localhost:4000

Available Queries and Mutations

Queries

• Get All Books:

  query {
    books {
      id
      title
      genre
      price
      author {
        name
      }
    }
  }

• Get All Authors:

  query {
    authors {
      id
      name
      bio
      books {
        title
      }
    }
  }

• Search Books and Authors:

  query {
    search(keyword: "Fantasy") {
      ...on Book {
        title
        price
      }
      ...on Author {
        name
        bio
      }
    }
  }

Mutations

• Add a Book:

  mutation {
    addBook(title: "The Hobbit", authorId: "3", genre: "Fantasy", price: 19.99) {
      id
      title
    }
  }

• Update a Book:

  mutation {
    updateBook(id: "1", title: "Updated Title", price: 29.99) {
      id
      title
      price
    }
  }

• Delete a Book:

  mutation {
    deleteBook(id: "2")
  }

Modifying the Schema

The schema is defined in typeDefs.js and can be easily modified to include additional types, fields, or mutations.

Troubleshooting

• Port Already in Use: If you encounter an error about the port being in use, make sure no other server is running on port 4000 or modify the port in index.js.

• GraphQL Playground Not Loading: Ensure the server is running without errors and that you’re accessing the correct URL (http://localhost:4000).
