## Usage Examples

### Incorrect

```graphql
# eslint @graphql-eslint/alphabetize: ['error', { fields: ['ObjectTypeDefinition'] }]

type User {
  password: String
  firstName: String! # should be before "password"
  age: Int # should be before "firstName"
  lastName: String!
}
```

### Correct

```graphql
# eslint @graphql-eslint/alphabetize: ['error', { fields: ['ObjectTypeDefinition'] }]

type User {
  age: Int
  firstName: String!
  lastName: String!
  password: String
}
```

### Incorrect

```graphql
# eslint @graphql-eslint/alphabetize: ['error', { values: ['EnumTypeDefinition'] }]

enum Role {
  SUPER_ADMIN
  ADMIN # should be before "SUPER_ADMIN"
  USER
  GOD # should be before "USER"
}
```

### Correct

```graphql
# eslint @graphql-eslint/alphabetize: ['error', { values: ['EnumTypeDefinition'] }]

enum Role {
  ADMIN
  GOD
  SUPER_ADMIN
  USER
}
```

### Incorrect

```graphql
# eslint @graphql-eslint/alphabetize: ['error', { selections: ['OperationDefinition'] }]

query {
  me {
    firstName
    lastName
    email # should be before "lastName"
  }
}
```

### Correct

```graphql
# eslint @graphql-eslint/alphabetize: ['error', { selections: ['OperationDefinition'] }]

query {
  me {
    email
    firstName
    lastName
  }
}
```
