Migrates the `db-mongodb` package to use `strict: true` and
`noUncheckedIndexedAccess: true` TSConfig properties.
This greatly improves code quality and prevents some runtime errors or
gives better error messages.
### What?
For the join field query adds ability to specify `count: true`, example:
```ts
const result = await payload.find({
joins: {
'group.relatedPosts': {
sort: '-title',
count: true,
},
},
collection: "categories",
})
result.group?.relatedPosts?.totalDocs // available
```
### Why?
Can be useful to implement full pagination / show total related
documents count in the UI.
### How?
Implements the logic in database adapters. In MongoDB it's additional
`$lookup` that has `$count` in the pipeline. In SQL, it's additional
subquery with `COUNT(*)`. Preserves the current behavior by default,
since counting introduces overhead.
Additionally, fixes a typescript generation error for join fields.
Before, `docs` and `hasNextPage` were marked as nullable, which is not
true, these fields cannot be `null`.
Additionally, fixes threading of `joinQuery` in
`transform/read/traverseFields` for group / tab fields recursive calls.
Previously, `hasNextPage` was working incorrectly with polymorphic joins
(that have an array of `collection`) in MongoDB.
This PR fixes it and adds extra assertions to the polymorphic joins
test.

This feature allows you to specify `collection` for the join field as
array.
This can be useful for example to describe relationship linking like
this:
```ts
{
slug: 'folders',
fields: [
{
type: 'join',
on: 'folder',
collection: ['files', 'documents', 'folders'],
name: 'children',
},
{
type: 'relationship',
relationTo: 'folders',
name: 'folder',
},
],
},
{
slug: 'files',
upload: true,
fields: [
{
type: 'relationship',
relationTo: 'folders',
name: 'folder',
},
],
},
{
slug: 'documents',
fields: [
{
type: 'relationship',
relationTo: 'folders',
name: 'folder',
},
],
},
```
Documents and files can be placed to folders and folders themselves can
be nested to other folders (root folders just have `folder` as `null`).
Output type of `Folder`:
```ts
export interface Folder {
id: string;
children?: {
docs?:
| (
| {
relationTo?: 'files';
value: string | File;
}
| {
relationTo?: 'documents';
value: string | Document;
}
| {
relationTo?: 'folders';
value: string | Folder;
}
)[]
| null;
hasNextPage?: boolean | null;
} | null;
folder?: (string | null) | Folder;
updatedAt: string;
createdAt: string;
}
```
While you could instead have many join fields (for example
`childrenFolders`, `childrenFiles`) etc - this doesn't allow you to
sort/filter and paginate things across many collections, which isn't
trivial. With SQL we use `UNION ALL` query to achieve that.

Currently, the join field outputs to its result `hasNextPage: boolean`
and have the `limit` query parameter but lacks `page` which can be
useful. This PR adds it.
The `localized` properly was not stripped out of referenced block fields, if any parent was localized. For normal fields, this is done in sanitizeConfig. As the same referenced block config can be used in both a localized and non-localized config, we are not able to strip it out inside sanitizeConfig by modifying the block config.
Instead, this PR had to bring back tedious logic to handle it everywhere the `field.localized` property is accessed. For backwards-compatibility, we need to keep the existing sanitizeConfig logic. In 4.0, we should remove it to benefit from better test coverage of runtime field.localized handling - for now, this is done for our test suite using the `PAYLOAD_DO_NOT_SANITIZE_LOCALIZED_PROPERTY` flag.
### What?
The join field had a limitation imposed that prevents it from targeting
polymorphic relationship fields. With this change we can support any
relationship fields.
### Why?
Improves the functionality of join field.
### How?
Extended the database adapters and removed the config sanitization that
would throw an error when polymorphic relationships were used.

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.

### What?
Makes it possible to filter join documents using a `where` added
directly in the config.
### Why?
It makes the join field more powerful for adding contextual meaning to
the documents being returned. For example, maybe you have a
`requiresAction` field that you set and you can have a join that
automatically filters the documents to those that need attention.
### How?
In the database adapter, we merge the requested `where` to the `where`
defined on the field.
On the frontend the results are filtered using the `filterOptions`
property in the component.

### What?
Properly specifies `$lookup.from` when the collection name is singular.
### Why?
MongoDB can pluralize the collection name and so can be different for
singular ones.
### How?
Uses the collection name from the driver directly
`adapter.collections[slug].collection.name` instead of just `slug`.
Adds `select` which is used to specify the field projection for local
and rest API calls. This is available as an optimization to reduce the
payload's of requests and make the database queries more efficient.
Includes:
- [x] generate types for the `select` property
- [x] infer the return type by `select` with 2 modes - include (`field:
true`) and exclude (`field: false`)
- [x] lots of integration tests, including deep fields / localization
etc
- [x] implement the property in db adapters
- [x] implement the property in the local api for most operations
- [x] implement the property in the rest api
- [x] docs

### What?
Allow specifying the defaultSort and defaultLimit to use for populating
a join field
### Why?
It is much easier to set defaults rather than be forced to always call
the join query using the query pattern ("?joins[categories][limit]=0").
### How?
See docs and type changes
## Description
- Adds a new "join" field type to Payload and is supported by all database adapters
- The UI uses a table view for the new field
- `db-mongodb` changes relationships to be stored as ObjectIDs instead of strings (for now querying works using both types internally to the DB so no data migration should be necessary unless you're querying directly, see breaking changes for details
- Adds a reusable traverseFields utility to Payload to make it easier to work with nested fields, used internally and for plugin maintainers
```ts
export const Categories: CollectionConfig = {
slug: 'categories',
fields: [
{
name: 'relatedPosts',
type: 'join',
collection: 'posts',
on: 'category',
}
]
}
```
BREAKING CHANGES:
All mongodb relationship and upload values will be stored as MongoDB ObjectIDs instead of strings going forward. If you have existing data and you are querying data directly, outside of Payload's APIs, you get different results. For example, a `contains` query will no longer works given a partial ID of a relationship since the ObjectID requires the whole identifier to work.
