Examples

Querys

Get all Books

query{
  getBooks{
    name
    year
    createdAt
    updatedAt
    library{
      name
      createdAt
      updatedAt
    }
  }
}

Get specific Library

query{
  getLibrary(id: 1){
    name
    createdAt
    updatedAt
    books{
      name
      year
      createdAt
      updatedAt
    }
  }
}

Mutations

Create a Library

mutation{
  createLibrary(post:{
    name: "California"
  }){
    code
    success
    message
    library{
      name
      createdAt
      updatedAt
      books{
        name
        year
        createdAt
        updatedAt
      }
    }
  }
}

Configuration

To ensure our work, we use Visual Studio Code and a few addons that will make our work much cleaner and professional.

• VSCode
• TablePlus

VSCode extensions

To install the add-ons necessary to work faster and cleaner we must go to the extension icon on the left panel and search all the add-on and installed.

• Apollo GraphQL
• Docker
• Eslint
• Path Intellisense
• Prettier

Folder Structure

The repository use the Domain-Driven File Structure.
