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.

## The SEO plugin now takes in a function to override or add in new
fields
- `fieldOverrides` has been removed
- `fields` is now a function that takes in `defaultFields` and expects
an array of fields in return
This makes it a lot easier for end users to override and extend existing
fields and add new ones. This change also brings this plugin inline with
the pattern that we use in our other plugins.
```ts
// before
seoPlugin({
fieldOverrides: {
title: {
required: true,
},
},
fields: [
{
name: 'customField',
type: 'text',
}
]
})
// after
seoPlugin({
fields: ({ defaultFields }) => {
const modifiedFields = defaultFields.map((field) => {
// Override existing fields
if ('name' in field && field.name === 'title') {
return {
...field,
required: true,
}
}
return field
})
return [
...modifiedFields,
// Add a new field
{
name: 'ogTitle',
type: 'text',
label: 'og:title',
},
]
},
})
```
## Also fixes
- Localization labels not showing up on default fields
- The inability to add before and after inputs to default fields
https://github.com/payloadcms/payload/issues/8893
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

## Type of change
- [x] New feature (non-breaking change which adds functionality)
## Checklist:
- [x] I have added tests that prove my fix is effective or that my
feature works
- [x] Existing test suite passes locally with my changes
- [x] I have made corresponding changes to the documentation
- Upgrades eslint from v8 to v9
- Upgrades all other eslint packages. We will have to do a new
full-project lint, as new rules have been added
- Upgrades husky from v8 to v9
- Upgrades lint-staged from v14 to v15
- Moves the old .eslintrc.cjs file format to the new eslint.config.js
flat file format.
Previously, we were very specific regarding which rules are applied to
which files. Now that `extends` is no longer a thing, I have to use
deepMerge & imports instead.
This is rather uncommon and is not a documented pattern - e.g.
typescript-eslint docs want us to add the default typescript-eslint
rules to the top-level & then disable it in files using the
disable-typechecked config.
However, I hate this opt-out approach. The way I did it here adds a lot
of clarity as to which rules are applied to which files, and is pretty
easy to read. Much less black magic
## .eslintignore
These files are no longer supported (see
https://eslint.org/docs/latest/use/configure/migration-guide#ignoring-files).
I moved the entries to the ignores property in the eslint config. => one
less file in each package folder!
Exports the fields from the SEO plugin so that they can be used anywhere
inside a collection, new exports:
```ts
import { MetaDescriptionField, MetaImageField, MetaTitleField, OverviewField, PreviewField } from '@payloadcms/plugin-seo/fields'
// Used as fields
MetaImageField({
relationTo: 'media',
hasGenerateFn: true,
})
MetaDescriptionField({
hasGenerateFn: true,
})
MetaTitleField({
hasGenerateFn: true,
})
PreviewField({
hasGenerateFn: true,
titlePath: 'meta.title',
descriptionPath: 'meta.description',
})
OverviewField({
titlePath: 'meta.title',
descriptionPath: 'meta.description',
imagePath: 'meta.image',
})
```
Removes PayloadRequestWithData in favour of just PayloadRequest with
optional types for `data` and `locale`
`addDataAndFileToRequest` and `addLocalesToRequestFromData` now takes in
a single argument instead of an object
```ts
// before
await addDataAndFileToRequest({ request: req })
addLocalesToRequestFromData({ request: req })
// current
await addDataAndFileToRequest(req)
addLocalesToRequestFromData(req)
```

Changed the data to correctly match type generic being sent to the
generate functions. So now you can type your generateTitle etc.
functions like this
```ts
// before
const generateTitle: GenerateTitle = async <Page>({ doc, locale }) => {
return `Website.com — ${doc?.title?.value}`
}
// curent
import type { GenerateDescription, GenerateTitle, GenerateURL } from '@payloadcms/plugin-seo/types'
import type { Page } from './payload-types'
const generateTitle: GenerateTitle<Page> = async ({ doc, locale }) => {
return `Website.com — ${doc?.title}`
}
const generateDescription: GenerateDescription<Page> = async ({ doc, locale }) => {
return doc?.excerpt || 'generated description'
}
const generateURL: GenerateURL<Page> = async ({ doc, locale }) => {
return `https://yoursite.com/${locale ? locale + '/' : ''}${doc?.slug || ''}`
}
```
Breaking change because it was previously a FormState value.
# Breaking Changes
### New file import locations
Exports from the `payload` package have been _significantly_ cleaned up.
Now, just about everything is able to be imported from `payload`
directly, rather than an assortment of subpath exports. This means that
things like `import { buildConfig } from 'payload/config'` are now just
imported via `import { buildConfig } from 'payload'`. The mental model
is significantly simpler for developers, but you might need to update
some of your imports.
Payload now exposes only three exports:
1. `payload` - all types and server-only Payload code
2. `payload/shared` - utilities that can be used in either the browser
or in Node environments
3. `payload/node` - heavy utilities that should only be imported in Node
scripts and never be imported into bundled code like Next.js
### UI library pre-bundling
With this release, we've dramatically sped up the compile time for
Payload by pre-bundling our entire UI package for use inside of the
Payload admin itself. There are new exports that should be used within
Payload custom components:
1. `@payloadcms/ui/client` - all client components
2. `@payloadcms/ui/server` - all server components
For all of your custom Payload admin UI components, you should be
importing from one of these two pre-compiled barrel files rather than
importing from the more deeply nested exports directly. That will keep
compile times nice and speedy, and will also make sure that the bundled
JS for your admin UI is kept small.
For example, whereas before, if you imported the Payload `Button`, you
would have imported it like this:
```ts
import { Button } from '@payloadcms/ui/elements/Button'
```
Now, you would import it like this:
```ts
import { Button } from '@payloadcms/ui/client'
```
This is a significant DX / performance optimization that we're pretty
pumped about.
However, if you are importing or re-using Payload UI components
_outside_ of the Payload admin UI, for example in your own frontend
apps, you can import from the individual component exports which will
make sure that the bundled JS is kept to a minimum in your frontend
apps. So in your own frontend, you can continue to import directly to
the components that you want to consume rather than importing from the
pre-compiled barrel files.
Individual component exports will now come with their corresponding CSS
and everything will work perfectly as-expected.
### Specific exports have changed
- `'@payloadcms/ui/templates/Default'` and
`'@payloadcms/ui/templates/Minimal`' are now exported from
`'@payloadcms/next/templates'`
- Old: `import { LogOut } from '@payloadcms/ui/icons/LogOut'` new:
`import { LogOutIcon } from '@payloadcms/ui/icons/LogOut'`
## Background info
In effort to make local dev as fast as possible, we need to import as
few files as possible so that the compiler has less to process. One way
we've achieved this in the Admin Panel was to _remove_ all .scss imports
from all components in the `@payloadcms/ui` module using a build
process. This stripped all `import './index.scss'` statements out of
each component before injecting them into `dist`. Instead, it bundles
all of the CSS into a single `main.css` file, and we import _that_ at
the root of the app.
While this concept is _still_ the right solution to the problem, this
particular approach is not viable when using these components outside
the Admin Panel, where not only does this root stylesheet not exist, but
where it would also bloat your app with unused styles. Instead, we need
to _keep_ these .scss imports in place so they are imported directly
alongside your components, as expected. Then, we need create a _new_
build step that _separately_ compiles the components _without_ their
stylesheets—this way your app can consume either as needed from the new
`client` and `server` barrel files within `@payloadcms/ui`, i.e. from
within `@payloadcms/next` and all other admin-specific packages and
plugins.
This way, all other applications will simply import using the direct
file paths, just as they did before. Except now they come with
stylesheets.
And we've gotten a pretty awesome initial compilation performance boost.
