This PR updates all react and next-related packages to the latest
version in our test directory and in our templates, while still allowing
older versions to be used.
Additionally, this ensures that the "scheduler" package version we
install matches the version installed by react-dom
If you had a lot of fields and collections, createClientConfig would be
extremely slow, as it was copying a lot of memory. In my test config
with a lot of fields and collections, it took 4 seconds(!!).
And not only that, it also ran between every single page navigation.
This PR significantly speeds up the createClientConfig function. In my
test config, its execution speed went from 4 seconds to 50 ms.
Additionally, createClientConfig is now properly cached in both dev &
prod. It no longer runs between every single page navigation. Even if
you trigger a full page reload, createClientConfig will be cached and
not run again. Despite that, HMR remains fully-functional.
This will make payload feel noticeably faster for large configs -
especially if it contains a lot of richtext fields, as it was previously
deep-copying the relatively large richText editor configs over and over
again.
## Before - 40 sec navigation speed

## After - 1 sec navigation speed

## Todo
- [x] Implement ClientSchemaMap and cache it, to remove
createClientField call in our form state endpoint
- [x] Enable schemaMap caching for dev
- [x] Cache lexical clientField generation, or add it to the parent
clientConfig
## Lexical changes
Red: old / removed
Green: new
### Speed up version queries
This PR comes with performance optimizations for fetching versions
before a document is loaded. Not only does it use the new select API to
limit the fields it queries, it also completely skips a database query
if the current document is published.
### Speed up lexical init
Removes a bunch of unnecessary deep copying of lexical objects which
caused higher memory usage and slower load times. Additionally, the
lexical default config sanitization now happens less often.
Deprecates `react-animate-height` in favor of native CSS, specifically
the `interpolate-size: allow-keywords;` property which can be used to
animate to `height: auto`—the primary reason this package exists. This
is one less dependency in our `node_modules`. Tried to replicate the
current DOM structure, class names, and API of `react-animate-height`
for best compatibility.
Note that this CSS property is experimental BUT this PR includes a patch
for browsers without native support. Once full support is reached, the
patch can be safely removed.
The field RSC now provides an initial state for all lexical blocks. This
completely obliterates any flashes and lexical block loading states when
loading or saving a document.
Previously, when a document is loaded or saved, every lexical block was
sending a network request in order to fetch their form state. Now, this
is batched and handled in the lexical server component. All lexical
block form states are sent to the client together with the parent
lexical field, and are thus available immediately.
We also do the same with block collapsed preferences. Thus, there are no
loading states or layout shifts/flashes of blocks anymore.
Additionally, when saving a document while your cursor is inside a
lexical field, the cursor position is preserved. Previously, a document
save would kick your cursor out of the lexical field.
## Look at how nice this is:

**BREAKING:**
This removes the `feature.hooks.load` and `feature.hooks.save`
interfaces from custom lexical features, as they weren't used internally
and added unnecessary, additional overhead.
If you have custom features that use those, you can migrate to using
normal payload hooks that run on the server instead of the client.
This fixes a peer dependency error in our monorepo, as
eslint-plugin-jsx-a11y finally supports eslint v9.
Additionally, this officially adds TypeScript 5.6 support for
typescript-eslint.
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.
