Deprecates `getPayloadHMR` and simplifies this pattern into a single
`import { getPayload } from 'payload'`.
We will still retain the exported `getPayloadHMR` but it now will throw
a deprecation warning with instructions for how to migrate.
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.

GraphQL currently doesn't pass CORS checks as we don't expose an OPTIONS
endpoint which is used for browser preflights.
Should also fix situations like this

The comments injected into auto-generated files have gotten misformatted
due to linting. Here is the proper format, where both comments are
adjacent to one another:
```js
/* THIS FILE WAS GENERATED AUTOMATICALLY BY PAYLOAD. */
/* DO NOT MODIFY IT BECAUSE IT COULD BE REWRITTEN AT ANY TIME. */
```
Some comments were also written with casing issues, here's an example:
```js
/* DO NOT MODIFY it because it could be re-written at any time. */
```
This noticeably improves performance in the admin panel, for example
when there are multiple richtext editors on one page (& likely
performance in other areas too, though I mainly tested rich text).
The babel plugin currently only optimizes files with a 'use client'
directive at the top - thus we have to make sure to add use client
wherever possible, even if it's imported by a parent client component.
There's one single component that broke when it was compiled using the
React compiler (it stopped being reactive and failed one of our admin
e2e tests):

opting out of it completely fixed that issue
