Author: The KeystoneJS Contrib Development Team
Latest version: 0.1.0

# List Plugins

# atTracking

Adds `createdAt` and `updatedAt` fields to a list. These fields are read-only by will be updated automatically when items are created or updated.

## Usage

```ts
import { atTracking } from '@k6-contrib/list-plugins';

const withAtTracking = atTracking({});

const User = list(withAtTracking({
  ui: {...},
  fields: {...},
  ...
}))
```

## Config

| Option           | Type     | Default             | Description                               |
| ---------------- | -------- | ------------------- | ----------------------------------------- |
| `createdAtField` | `String` | `createdAt`         | Name of the `createdAt` field.            |
| `updatedAtField` | `String` | `updatedAt`         | Name of the `createdAt` field.            |
| `format`         | `String` | `MM/DD/YYYY h:mm A` | Format of the generated `DateTime` field. |
| `access`         | `Object` | See: access         | Change default access controls.           |

### `access`

By default access control on at tracking fields is read only:

```javascript
{
  read: true,
  create: false,
  update: false
}
```

## Disabling created or updated

You can import _either_ `createdAt` or `updatedAt` to apply a single tracking field:

```javascript
const { createdAt, updatedAt } = require('@keystonejs/list-plugins');
```

_Note_: The API is the same.

# byTracking

Adds `createdBy` and `updatedBy` fields to a list. These fields are read-only by will be updated automatically when items are created or updated.

## Usage

```ts
import { byTracking } from '@k6-contrib/list-plugins';

const withByTracking = byTracking({});

const User = list(withByTracking({
  ui: {...},
  fields: {...},
  ...
}))
```

# singleton

## NOT ported

~~This plugin makes a list singleton by allowing only one item in the list. Useful for list which must contain only one items.~~

# logging

This plugin provides a mechanism for logging all mutations in a Keystone system.

## Usage

```ts
const { logging } = require('@k6-contrib/list-plugins');

const withLogging = logging();
const withLogging = logging(args => console.log(args));

const User = list(withLogging({
  ui: {...},
  fields: {...},
  ...
}))

```

## Provided hooks

The `logging` plugin will log the arguments of all mutations with the function `args => console.log(JSON.stringify(args))`.
You can customise its behaviour by providing an alternate logging function.

The plugin provides the following hooks:

- `afterChange`
- `afterDelete`
- `afterAuth`
- `afterUnauth`

The logging function for each hook recieves specific arguments related to the mutation.
