Express-GraphQL Bookstore API

This is a sample project showcasing an API built using Express, express-graphql, and GraphQL. It provides a set of GraphQL queries and mutations to interact with authors and their books. Whether you're looking to retrieve book information, author details, or perform operations like adding new books or updating existing ones, this API has got you covered.

Tech Stack

• express: Used as the web server framework.
• express-graphql: Provides a simple way to create an Express server that runs a GraphQL API.
• graphql: Used to define the API schema and resolve queries and mutations.

Features

1. Queries:

   • Fetch all authors
   • Fetch an author by ID
   • Fetch all books
   • Fetch a book by ID

2. Mutations:

   • Add a new author
   • Add a new book under an author

Getting Started

1. Clone this repository
2. Navigate to the project directory and run npm install to install all dependencies.
3. Start the development server using:

npm run dev

This will start the server using nodemon, which will automatically restart your server upon code changes. By default, the server is started on port 5000, but you can modify server.js to choose a different port.

4. Once the server is running, navigate to http://localhost:5000/graphql in your browser to access the GraphQL playground. Here, you can test out queries, mutations, and explore the schema.

Fetch all books

query {
	books {
        id,
        title,
        author {
        name
        }
    }
}

Fetch a book by ID

query {
  book(id:1) {
    author {
      name
    }
  }
}

Fetch all authors

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

Fetch an author by ID

query {
	author(id:1) {
    name,
    books{
      title
    }
  }
}

Add a new book under an author

mutation {
    addBook(title: "Gym", authorId: 1) {
        id
    }
}

Add a new author

mutation {
    addAuthor(name:"dale") {
        id
    }
}

Further Work

As this is a sample project, there's always room for expansion. Future work could involve adding user authentication, expanding the data model, or integrating a database for persistent storage.
