In modern backend applications, many programming languages can be chosen, including Go—a programming language that provides high performance with concise syntax and can also be used to develop backend applications, including REST API and GraphQL applications. This course will cover many tools that can be used to develop a backend application, including fiber for REST API application, gqlgen for GraphQL application, and apitest for testing purposes.

In this course, you’ll learn about the main concepts of web applications, including HTTP, REST API, databases, and GraphQL. You’ll cover how to develop a backend application and deploy the application as well. 

By the end of the course, you’ll be able to develop a backend application using REST API and GraphQL approach. Also, you’ll be able to test and deploy the backend application that has been developed.

Building a Backend Application with Go

GraphQL has a similar approach to REST API.


GraphQL is only able to return all the data even if the client has not requested it.


GraphQL only returns the data that is requested or asked for by the client.


GraphQL applications only support non-relational databases.


```graphql
query {
 blogs {
    title
    content
  }
}
```

```graphql
select {
 blogs {
    title
    content
  }
}
```

```graphql
query {
 blogs {
    blog {
      title
      content
    }
  }
}
```

```graphql
query {
 blogs {
    blog { title, content }
  }
}
```

The client only needs the title and the content of the blog data. What kind of query is suitable for this case?

The client only needs the title and the content of the blog data. What kind of query is suitable for this case?

```graphql
type Category {
 id: ID!
 name: String!
}

type Book {
  id: ID!
  title: String!
  description: String!
  isbn: String!
  category_id: ID!
}
```

```graphql
type Category {
 id: ID!
 name: String!
}

type Book {
  id: ID!
  title: String!
  description: String!
  isbn: String!
  category: Category!
}
```

```graphql
type Category {
 id: ID
 name: String
}

type Book {
  id: ID
  title: String
  description: String
  isbn: String
  category: Category
}
```

```graphql
type Book {
  id: ID!
  title: String!
  description: String!
  isbn: String!
  category: String!
}
```

A library wants to manage its book data by using the GraphQL application. The book’s attributes stored inside the application are title, description, ISBN, and category. What kind of schema is suitable for this case?

  category: Category!
}

type Mutation {

}

```

```graphql
type Mutation {
  createBook(input: Book!): Book!
}

```
