Currently, Payload renders all custom components on initial compile of
the admin panel. This is problematic for two key reasons:
1. Custom components do not receive contextual data, i.e. fields do not
receive their field data, edit views do not receive their document data,
etc.
2. Components are unnecessarily rendered before they are used
This was initially required to support React Server Components within
the Payload Admin Panel for two key reasons:
1. Fields can be dynamically rendered within arrays, blocks, etc.
2. Documents can be recursively rendered within a "drawer" UI, i.e.
relationship fields
3. Payload supports server/client component composition
In order to achieve this, components need to be rendered on the server
and passed as "slots" to the client. Currently, the pattern for this is
to render custom server components in the "client config". Then when a
view or field is needed to be rendered, we first check the client config
for a "pre-rendered" component, otherwise render our client-side
fallback component.
But for the reasons listed above, this pattern doesn't exactly make
custom server components very useful within the Payload Admin Panel,
which is where this PR comes in. Now, instead of pre-rendering all
components on initial compile, we're able to render custom components
_on demand_, only as they are needed.
To achieve this, we've established [this
pattern](https://github.com/payloadcms/payload/pull/8481) of React
Server Functions in the Payload Admin Panel. With Server Functions, we
can iterate the Payload Config and return JSX through React's
`text/x-component` content-type. This means we're able to pass
contextual props to custom components, such as data for fields and
views.
## Breaking Changes
1. Add the following to your root layout file, typically located at
`(app)/(payload)/layout.tsx`:
```diff
/* THIS FILE WAS GENERATED AUTOMATICALLY BY PAYLOAD. */
/* DO NOT MODIFY IT BECAUSE IT COULD BE REWRITTEN AT ANY TIME. */
+ import type { ServerFunctionClient } from 'payload'
import config from '@payload-config'
import { RootLayout } from '@payloadcms/next/layouts'
import { handleServerFunctions } from '@payloadcms/next/utilities'
import React from 'react'
import { importMap } from './admin/importMap.js'
import './custom.scss'
type Args = {
children: React.ReactNode
}
+ const serverFunctions: ServerFunctionClient = async function (args) {
+ 'use server'
+ return handleServerFunctions({
+ ...args,
+ config,
+ importMap,
+ })
+ }
const Layout = ({ children }: Args) => (
<RootLayout
config={config}
importMap={importMap}
+ serverFunctions={serverFunctions}
>
{children}
</RootLayout>
)
export default Layout
```
2. If you were previously posting to the `/api/form-state` endpoint, it
no longer exists. Instead, you'll need to invoke the `form-state` Server
Function, which can be done through the _new_ `getFormState` utility:
```diff
- import { getFormState } from '@payloadcms/ui'
- const { state } = await getFormState({
- apiRoute: '',
- body: {
- // ...
- },
- serverURL: ''
- })
+ const { getFormState } = useServerFunctions()
+
+ const { state } = await getFormState({
+ // ...
+ })
```
## Breaking Changes
```diff
- useFieldProps()
- useCellProps()
```
More details coming soon.

Fixes https://github.com/payloadcms/payload/issues/8534
UI fields are now excluded by default from the bulk edit view fields
options.
If you need to have the UI field there, you can provide:
```ts
admin: {
disableBulkEdit: false
}
```
## Description
### TL;DR:
It's currently not possible to render our field components from a server
component because their `field` prop is the original field config, not
the _client_ config which our components require. Currently, the `field`
prop passed into custom fields changes type depending on whether it's a
server or client component, leaving server components without any access
to the client field config or mechanism to acquire it.
This PR passes the client config to all server field components through
a new `clientField` prop. This allows the following in a server
component, which is very similar to how client field components
currently work:
Server component:
```tsx
import { TextField } from '@payloadcms/ui'
import type { TextFieldServerComponent } from 'payload'
export const MyCustomServerField: TextFieldServerComponent = ({ clientField }) => {
return <TextField field={clientField} />
}
```
Client component:
```tsx
'use client'
import { TextField } from '@payloadcms/ui'
import type { TextFieldClientComponent } from 'payload'
export const MyCustomClientField: TextFieldClientComponent = ({ field }) => {
return <TextField field={field} />
}
```
### Full Background
If you have a custom field component, and it's a server component, there
is currently no way to pass the field prop into Payload's client-side
field components.
Here's an example of the problem:
```tsx
import { TextField } from '@payloadcms/ui'
import type { TextFieldServerComponent } from 'payload'
import React from 'react'
export const MyServerComponent: TextFieldServerComponent = (props) => {
const { field } = props
return (
<TextField field={field} /> // This is not possible
)
}
```
The config needs to be transformed into a client config, however,
because of the sheer number of hard-to-find arguments that the
`createClientField` requires, we cannot use it in its raw form.
Here is another example of the problem:
```tsx
import { TextField } from '@payloadcms/ui'
import { createClientField } from '@payloadcms/ui/utilities/createClientField'
import type { TextFieldServerComponent } from 'payload'
import React from 'react'
export const MyServerComponent: TextFieldServerComponent = ({ createClientField }) => {
const clientField = createClientField({...}) // Not a good option bc it requires many hard-to-find args
return (
<TextField field={clientField} />
)
}
```
Theoretically, we could preformat a `createFieldConfig` function so it
can simply be called without arguments:
```tsx
import { TextField } from '@payloadcms/ui'
import type { TextFieldServerComponent } from 'payload'
import React from 'react'
export const MyServerComponent: TextFieldServerComponent = ({ createClientField }) => {
return <TextField field={createClientField()} />
}
```
But this means the field config would be evaluated twice unnecessarily,
including label functions, etc.
The right way to fix this is to simply pass the client config to server
components through a new `clientField` prop:
```tsx
import { TextField } from '@payloadcms/ui'
import type { TextFieldServerComponent } from 'payload'
import React from 'react'
export const MyServerComponent: TextFieldServerComponent = ({ clientField }) => {
return <TextField field={clientField} />
}
```

## Description
Currently, there is no way of typing custom server field components.
This is because internally, all field components are client components,
and so these were never fully typed. For example, the docs currently
indicate for all custom fields to be typed in this way:
Old:
```tsx
export const MyClientTextFieldComponent: React.FC<TextFieldProps>
```
But if your component is a server component, you will never receive the
fully typed `field` prop, `payload` prop, etc. unless you've typed that
yourself using some of the underlying utilities. So to fix this, every
field now explicitly exports a type for each environment:
New:
- Client component:
```tsx
'use client'
export const MyClientTextFieldComponent: TextFieldClientComponent
```
- Server component:
```tsx
export const MyServerTextFieldComponent: TextFieldServerComponent
```
This pattern applies to every field type, where the field name is
prepended onto the component type.
```ts
import type {
TextFieldClientComponent,
TextFieldServerComponent,
TextFieldClientProps,
TextFieldServerProps,
TextareaFieldClientComponent,
TextareaFieldServerComponent,
TextareaFieldClientProps,
TextareaFieldServerProps,
// ...and so on for each field type
} from 'payload'
```
## BREAKING CHANGES
We are no longer exporting `TextFieldProps` etc. for each field type.
Instead, we now export props for each client/server environment
explicitly. If you were previously importing one of these types into
your custom component, simply change the import name to reflect your
environment.
Old:
```tsx
import type { TextFieldProps } from 'payload'
```
New:
```tsx
import type { TextFieldClientProps, TextFieldServerProps } from 'payload'
```

## Description
Threads the field config to all "field subcomponents" through props,
i.e. field label, description, error, etc. This way, the field config
that controls any particular component is easily accessible and strongly
typed, i.e. `props.field.maxLength`. This is true for both server and
client components, whose server-side props are now also contextually
typed. This behavior was temporarily removed in #7474 due to bloating
HTML, but has since been resolved in #7620. This PR also makes
significant improvements to component types by exporting explicit types
for _every component of every field_, each with its own client/server
variation. Now, a custom component can look something like this:
```tsx
import type { TextFieldLabelServerComponent } from 'payload'
import React from 'react'
export const CustomLabel: TextFieldLabelServerComponent = (props) => {
return (
<div>{`The max length of this field is: ${props?.field?.maxLength}`}</div>
)
}
```
The following types are now available:
```ts
import type {
TextFieldClientComponent,
TextFieldServerComponent,
TextFieldLabelClientComponent,
TextFieldLabelServerComponent,
TextFieldDescriptionClientComponent,
TextFieldDescriptionServerComponent,
TextFieldErrorClientComponent,
TextFieldErrorServerComponent,
// ...and so one for each field
} from 'payload'
```
BREAKING CHANGES:
In order to strictly type these components, a few breaking changes have
been made _solely to type definitions_. This only effects you if you are
heavily using custom components.
Old
```ts
import type { ErrorComponent, LabelComponent, DescriptionComponent } from 'payload'
```
New:
```ts
import type {
FieldErrorClientComponent,
FieldErrorServerComponent,
FieldLabelClientComponent,
FieldLabelServerComponent,
FieldDescriptionClientComponent,
FieldDescriptionServerComponent,
// Note: these are the generic, underlying types of the more stricter types described above ^
// For example, you should use the type that is explicit for your particular field and environment
// i.e. `TextFieldLabelClientComponent` and not simply `FieldLabelClientComponent`
} from 'payload'

This PR makes three major changes to the codebase:
1. [Component Paths](#component-paths)
Instead of importing custom components into your config directly, they
are now defined as file paths and rendered only when needed. That way
the Payload config will be significantly more lightweight, and ensures
that the Payload config is 100% server-only and Node-safe. Related
discussion: https://github.com/payloadcms/payload/discussions/6938
2. [Client Config](#client-config)
Deprecates the component map by merging its logic into the client
config. The main goal of this change is for performance and
simplification. There was no need to deeply iterate over the Payload
config twice, once for the component map, and another for the client
config. Instead, we can do everything in the client config one time.
This has also dramatically simplified the client side prop drilling
through the UI library. Now, all components can share the same client
config which matches the exact shape of their Payload config (with the
exception of non-serializable props and mapped custom components).
3. [Custom client component are no longer
server-rendered](#custom-client-components-are-no-longer-server-rendered)
Previously, custom components would be server-rendered, no matter if
they are server or client components. Now, only server components are
rendered on the server. Client components are automatically detected,
and simply get passed through as `MappedComponent` to be rendered fully
client-side.
## Component Paths
Instead of importing custom components into your config directly, they
are now defined as file paths and rendered only when needed. That way
the Payload config will be significantly more lightweight, and ensures
that the Payload config is 100% server-only and Node-safe. Related
discussion: https://github.com/payloadcms/payload/discussions/6938
In order to reference any custom components in the Payload config, you
now have to specify a string path to the component instead of importing
it.
Old:
```ts
import { MyComponent2} from './MyComponent2.js'
admin: {
components: {
Label: MyComponent2
},
},
```
New:
```ts
admin: {
components: {
Label: '/collections/Posts/MyComponent2.js#MyComponent2', // <= has to be a relative path based on a baseDir configured in the Payload config - NOT relative based on the importing file
},
},
```
### Local API within Next.js routes
Previously, if you used the Payload Local API within Next.js pages, all
the client-side modules are being added to the bundle for that specific
page, even if you only need server-side functionality.
This `/test` route, which uses the Payload local API, was previously 460
kb. It is now down to 91 kb and does not bundle the Payload client-side
admin panel anymore.
All tests done
[here](https://github.com/payloadcms/payload-3.0-demo/tree/feat/path-test)
with beta.67/PR, db-mongodb and default richtext-lexical:
**dev /admin before:**
**dev /admin after:**
---
**dev /test before:**
**dev /test after:**
---
**build before:**
**build after::**
### Usage of the Payload Local API / config outside of Next.js
This will make it a lot easier to use the Payload config / local API in
other, server-side contexts. Previously, you might encounter errors due
to client files (like .scss files) not being allowed to be imported.
## Client Config
Deprecates the component map by merging its logic into the client
config. The main goal of this change is for performance and
simplification. There was no need to deeply iterate over the Payload
config twice, once for the component map, and another for the client
config. Instead, we can do everything in the client config one time.
This has also dramatically simplified the client side prop drilling
through the UI library. Now, all components can share the same client
config which matches the exact shape of their Payload config (with the
exception of non-serializable props and mapped custom components).
This is breaking change. The `useComponentMap` hook no longer exists,
and most component props have changed (for the better):
```ts
const { componentMap } = useComponentMap() // old
const { config } = useConfig() // new
```
The `useConfig` hook has also changed in shape, `config` is now a
property _within_ the context obj:
```ts
const config = useConfig() // old
const { config } = useConfig() // new
```
## Custom Client Components are no longer server rendered
Previously, custom components would be server-rendered, no matter if
they are server or client components. Now, only server components are
rendered on the server. Client components are automatically detected,
and simply get passed through as `MappedComponent` to be rendered fully
client-side.
The benefit of this change:
Custom client components can now receive props. Previously, the only way
for them to receive dynamic props from a parent client component was to
use hooks, e.g. `useFieldProps()`. Now, we do have the option of passing
in props to the custom components directly, if they are client
components. This will be simpler than having to look for the correct
hook.
This makes rendering them on the client a little bit more complex, as
you now have to check if that component is a server component (=>
already has been rendered) or a client component (=> not rendered yet,
has to be rendered here). However, this added complexity has been
alleviated through the easy-to-use `<RenderMappedComponent />` helper.
This helper now also handles rendering arrays of custom components (e.g.
beforeList, beforeLogin ...), which actually makes rendering custom
components easier in some cases.
## Misc improvements
This PR includes misc, breaking changes. For example, we previously
allowed unions between components and config object for the same
property. E.g. for the custom view property, you were allowed to pass in
a custom component or an object with other properties, alongside a
custom component.
Those union types are now gone. You can now either pass an object, or a
component. The previous `{ View: MyViewComponent}` is now `{ View: {
Component: MyViewComponent} }` or `{ View: { Default: { Component:
MyViewComponent} } }`.
This dramatically simplifies the way we read & process those properties,
especially in buildComponentMap. We can now simply check for the
existence of one specific property, which always has to be a component,
instead of running cursed runtime checks on a shared union property
which could contain a component, but could also contain functions or
objects.

## 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
