This project is a Java Spring Boot application that provides a GraphQL API for users to place orders on various products. The application is containerized using Docker, making it easy to deploy and run in a consistent environment. Testing can be performed using GraphiQL, and no front-end is required.

1. User Registration:

   • Users can register for an account with the application.

2. User Sign-In:

   • Registered users can sign in to their accounts.

3. Product Creation:

   • Registered users can create new products using GraphQL mutations.

4. Order Placement:

   • Users can place orders for different products using GraphQL queries.

5. GraphiQL Testing:

   • Testing and exploring the GraphQL API can be done conveniently using GraphiQL.

• Backend:

  • Java Spring Boot: A Java-based framework for building robust and scalable backend applications.
  • GraphQL: A query language for APIs that provides a more efficient and powerful alternative to traditional REST.
  • JWT: JSON Web Tokens for authentication.

• Database:

  • H2 Database: A lightweight, in-memory database for development and testing.

• Containerization:

  • Docker: Containerization platform for packaging applications and their dependencies.

• Build and Dependency Management:

  • Maven: Dependency management tool used to streamline the build process.

• getAllUsers:

  • Returns a list of all users.

• getUserById(id):

  • Returns details for a specific user identified by the provided ID.

• getAllProducts:

  • Returns a list of all products.

• getProductsByOrderId(id):

  • Returns a list of products associated with a specific order ID.

• getAllOrders:

  • Returns a list of all orders.

• getOrderById(id):

  • Returns details for a specific order identified by the provided ID.

• getOrdersByUserId(id):

  • Returns a list of orders associated with a specific user ID.

• createUser(input):

  • Creates a new user based on the provided input.

• updateUser(id, input):

  • Updates user details for the user identified by the provided ID.

• deleteUser(id):

  • Deletes a user identified by the provided ID.

• createProduct(input):

  • Creates a new product based on the provided input.

• updateProduct(id, input):

  • Updates product details for the product identified by the provided ID.

• deleteProduct(id):

  • Deletes a product identified by the provided ID.

• createOrder(input, userId):

  • Creates a new order based on the provided input and user ID.

• updateOrder(id, input):

  • Updates order details for the order identified by the provided ID.

• deleteOrder(id):

  • Deletes an order identified by the provided ID.

• login(input):

  • Performs user authentication and returns authentication details.

• Use these GraphQL queries, mutations, and types to interact with the API.
• For mutations that require authentication, include the JWT token in the header as follows:
• To test GraphQL endpoints requiring authentication, include the JWT token in the header as follows: Authorization: Bearer in JSON format. Example: { "Authorization": "Bearer YOUR_ACCESS_TOKEN"}
• The Jwt token is generated when you sign in to your account. You must first create an account and sign in to obtain the token.

To access the H2 Console for database management, follow these steps:

1. Start your Spring Boot application.

2. Open a web browser and go to http://localhost:8080/h2-console.

3. Use the following H2 database connection settings:

   • JDBC URL: jdbc:h2:mem:myDatabase
   • Username: sa
   • Password: (use password in application.properties)

4. Click the "Connect" button.

5. Explore and manage your H2 database using the H2 Console.
