Transforms [Slonik](https://github.com/gajus/slonik) query result field names.

> [!WARNING]

> Deprecated in favor of https://github.com/gajus/slonik monorepo.

## Motivation

This interceptor removes the necessity to alias field names, e.g.

```ts

connection.any(sql`

  SELECT

    id,

    full_name "fullName"

  FROM person

`);

```

Field name transformation uses `afterQuery` interceptor method to format field names.

## API

```ts

import {

  createFieldNameTransformationInterceptor

} from 'slonik-interceptor-field-name-transformation';

```

```ts

/**

 * @property format The only supported format is CAMEL_CASE.

 * @property test Tests whether the field should be formatted. The default behaviour is to include all fields that match ^[a-z0-9_]+$ regex.

 */

type ConfigurationType = {|

  +format: 'CAMEL_CASE',

  +test: (field: FieldType) => boolean

|};

(configuration: ConfigurationType) => InterceptorType;

```

## Example usage

```ts

import {

  createPool

} from 'slonik';

import {

  createFieldNameTransformationInterceptor

} from 'slonik-interceptor-field-name-transformation';

const interceptors = [

  createFieldNameTransformationInterceptor({

    format: 'CAMEL_CASE'

  })

];

const connection = createPool('postgres://', {

  interceptors

});

connection.any(sql`

  SELECT

    id,

    full_name

  FROM person

`);

// [

//   {

//     id: 1,

//     fullName: 1

//   }

// ]

```
