## Description
Currently, there is no way to read field props from within a custom
field component, i.e. `admin.components.Description`. For example, if
you set `maxLength: 100` on your field, your custom description
component cannot read it from `props.maxLength` or any other methods.
Because these components are rendered on the server, there is also no
way of using `admin.component.Field` to inject custom props yourself,
either. To support this, we can simply pass the base component props
into these components on the server, as expected. This has also led to
custom field component props becoming more strictly typed within the
config.
This change is considered breaking only because the types have changed.
This only affects you if you were previously importing the following
types into your own custom components. To migrate, simply change the
import paths for that type.
Old:
```ts
import type {
ArrayFieldProps,
ReducedBlock,
BlocksFieldProps,
CheckboxFieldProps,
CodeFieldProps,
CollapsibleFieldProps,
DateFieldProps,
EmailFieldProps,
GroupFieldProps,
HiddenFieldProps,
JSONFieldProps,
NumberFieldProps,
PointFieldProps,
RadioFieldProps,
RelationshipFieldProps,
RichTextComponentProps,
RowFieldProps,
SelectFieldProps,
TabsFieldProps,
TextFieldProps,
TextareaFieldProps,
UploadFieldProps,
ErrorProps,
FormFieldBase,
FieldComponentProps,
FieldMap,
MappedField,
MappedTab,
ReducedBlock,
} from '@payloadcms/ui'
```
New:
```ts
import type {
FormFieldBase,
// etc.
} from 'payload'
```
Custom field components are now much more strongly typed. To make this
happen, an explicit type for every custom component has been generated
for every field type. The convention is to append
`DescriptionComponent`, `LabelComponent`, and `ErrorComponent` onto the
end of the field name, i.e. `TextFieldDescriptionComponent`. Here's an
example:
```ts
import type { TextFieldDescriptionComponent } from 'payload'
import React from 'react'
export const CustomDescription: TextFieldDescriptionComponent = (props) => {
return (
<div id="custom-field-description">{`The max length of this field is: ${props?.maxLength}`}</div>
)
}
```
Here's the full list of all new types:
Label Components:
```ts
import type {
ArrayFieldLabelComponent,
BlocksFieldLabelComponent,
CheckboxFieldLabelComponent,
CodeFieldLabelComponent,
CollapsibleFieldLabelComponent,
DateFieldLabelComponent,
EmailFieldLabelComponent,
GroupFieldLabelComponent,
HiddenFieldLabelComponent,
JSONFieldLabelComponent,
NumberFieldLabelComponent,
PointFieldLabelComponent,
RadioFieldLabelComponent,
RelationshipFieldLabelComponent,
RichTextFieldLabelComponent,
RowFieldLabelComponent,
SelectFieldLabelComponent,
TabsFieldLabelComponent,
TextFieldLabelComponent,
TextareaFieldLabelComponent,
UploadFieldLabelComponent
} from 'payload'
```
Error Components:
```tsx
import type {
ArrayFieldErrorComponent,
BlocksFieldErrorComponent,
CheckboxFieldErrorComponent,
CodeFieldErrorComponent,
CollapsibleFieldErrorComponent,
DateFieldErrorComponent,
EmailFieldErrorComponent,
GroupFieldErrorComponent,
HiddenFieldErrorComponent,
JSONFieldErrorComponent,
NumberFieldErrorComponent,
PointFieldErrorComponent,
RadioFieldErrorComponent,
RelationshipFieldErrorComponent,
RichTextFieldErrorComponent,
RowFieldErrorComponent,
SelectFieldErrorComponent,
TabsFieldErrorComponent,
TextFieldErrorComponent,
TextareaFieldErrorComponent,
UploadFieldErrorComponent
} from 'payload'
```
Description Components:
```tsx
import type {
ArrayFieldDescriptionComponent,
BlocksFieldDescriptionComponent,
CheckboxFieldDescriptionComponent,
CodeFieldDescriptionComponent,
CollapsibleFieldDescriptionComponent,
DateFieldDescriptionComponent,
EmailFieldDescriptionComponent,
GroupFieldDescriptionComponent,
HiddenFieldDescriptionComponent,
JSONFieldDescriptionComponent,
NumberFieldDescriptionComponent,
PointFieldDescriptionComponent,
RadioFieldDescriptionComponent,
RelationshipFieldDescriptionComponent,
RichTextFieldDescriptionComponent,
RowFieldDescriptionComponent,
SelectFieldDescriptionComponent,
TabsFieldDescriptionComponent,
TextFieldDescriptionComponent,
TextareaFieldDescriptionComponent,
UploadFieldDescriptionComponent
} from 'payload'
```
This PR also:
- Standardizes the `FieldBase['label']` type with a new `LabelStatic`
type. This makes type usage much more consistent across components.
- Simplifies some of the typings in the field component map, removes
unneeded `<Omit>`, etc.
- Fixes misc. linting issues around voiding promises
