This PR allows to have full type safety on `payload.drizzle` with a
single command
```sh
pnpm payload generate:db-schema
```
Which generates TypeScript code with Drizzle declarations based on the
current database schema.

We also now proxy drizzle package the same way we do for Lexical so you
don't have to install it (and you shouldn't because you may have version
mismatch).
Instead, you can import from Drizzle like this:
```ts
import {
pgTable,
index,
foreignKey,
integer,
text,
varchar,
jsonb,
boolean,
numeric,
serial,
timestamp,
uniqueIndex,
pgEnum,
} from '@payloadcms/db-postgres/drizzle/pg-core'
import { sql } from '@payloadcms/db-postgres/drizzle'
import { relations } from '@payloadcms/db-postgres/drizzle/relations'
```
Fixes https://github.com/payloadcms/payload/discussions/4318
In the future we can also support types generation for mongoose / raw
mongodb results.
This PR adds a feature which fixes another issue with migrations in
Postgres and does few refactors that significantly reduce code
duplication.
Previously, if you needed to use the underlying database directly in
migrations with the active transaction (for example to execute raw SQL),
created from `payload create:migration`, as `req` doesn't work there you
had to do something like this:
```ts
// Postgres
export async function up({ payload, req }: MigrateUpArgs): Promise<void> {
const db = payload.db.sessions?.[await req.transactionID!].db ?? payload.db
const { rows: posts } = await db.execute(sql`SELECT * from posts`)
}
// MongoDB
export async function up({ payload, req }: MigrateUpArgs): Promise<void> {
const session = payload.db.sessions?.[await req.transactionID!]
const posts = await payload.db.collections.posts.collection.find({ session }).toArray()
}
```
Which was:
1. Awkward to write
2. Not documented anywhere
Now, we expose `session` and `db` to `up` and `down` functions for you:
#### MongoDB:
```ts
import { type MigrateUpArgs } from '@payloadcms/db-mongodb'
export async function up({ session, payload, req }: MigrateUpArgs): Promise<void> {
const posts = await payload.db.collections.posts.collection.find({ session }).toArray()
}
```
#### Postgres:
```ts
import { type MigrateUpArgs, sql } from '@payloadcms/db-postgres'
export async function up({ db, payload, req }: MigrateUpArgs): Promise<void> {
const { rows: posts } = await db.execute(sql`SELECT * from posts`)
}
```
#### SQLite:
```ts
import { type MigrateUpArgs, sql } from '@payloadcms/db-sqlite'
export async function up({ db, payload, req }: MigrateUpArgs): Promise<void> {
const { rows: posts } = await db.run(sql`SELECT * from posts`)
}
```
This actually was a thing with Postgres migrations, we already were
passing `db`, but:
1. Only for `up` and when running `payload migrate`, not for example
with `payload migrate:fresh`
2. Not documented neither in TypeScript or docs.
By ensuring we use `db`, this also fixes an issue that affects all
Postgres/SQLite migrations:
Currently, if we run `payload migration:create` with the postgres
adapter we get a file like this:
```ts
import { MigrateUpArgs, MigrateDownArgs, sql } from '@payloadcms/db-postgres'
export async function up({ payload, req }: MigrateUpArgs): Promise<void> {
await payload.db.drizzle.execute(sql`
CREATE TABLE IF NOT EXISTS "users" (
"id" serial PRIMARY KEY NOT NULL,
);
```
Looks good?
Not exactly!
`payload.db.drizzle.execute()` doesn't really use the current
transaction which can lead to some problems.
Instead, it should use the `db` from `payload.db.sessions?.[await
req.transactionID!].db` because that's where we store our Drizzle
instance with the transaction.
But now, if we generate `payload migrate:create` we get:
```ts
import { MigrateUpArgs, MigrateDownArgs, sql } from '@payloadcms/db-postgres'
export async function up({ db, payload, req }: MigrateUpArgs): Promise<void> {
await db.execute(sql`
CREATE TABLE IF NOT EXISTS "users" (
"id" serial PRIMARY KEY NOT NULL,
);
```
Which is what we want, as the `db` is passed correctly here:
76428373e4/packages/drizzle/src/migrate.ts (L88-L90)
```ts
export async function up({ db, payload, req }: MigrateUpArgs): Promise<void> {
const dbWithTransaction = payload.db.sessions?.[await req.transactionID!].db
payload.logger.info({ one: db === dbWithTransaction })
payload.logger.info({ two: db === payload.db.drizzle })
```

Additionally, this PR refactors:
* `createMigration` with Drizzle - now we have sharable
`buildCreateMigration` in `@payloadcms/drizzle` to reduce copy-pasting
of the same logic.
* the `v2-v3` relationships migration for Postgres is now shared between
`db-postgres` and `db-vercel-postgres`, again to reduce copy-paste.
### What?
This command from here:
https://github.com/payloadcms/payload/pull/6339
```sh
payload migrate:create --file @payloadcms/db-postgres/relationships-v2-v3
```
stopped working after db-postgers and drizzle packages were separated
### How?
Passes correct `dirname` to `getPredefinedMigration`
Additionally, adds support for `.js` files in `getPredefinedMigration`
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()
```

### What?
Adds full support for the point field to Postgres and Vercel Postgres
adapters through the Postgis extension. Fully the same API as with
MongoDB, including support for `near`, `within` and `intersects`
operators.
Additionally, exposes to adapter args:
*
`tablesFilter`https://orm.drizzle.team/docs/drizzle-kit-push#including-tables-schemas-and-extensions.
* `extensions` list of extensions to create, for example `['vector',
'pg_search']`, `postgis` is created automatically if there's any point
field
### Why?
It's essential to support that field type, especially if the postgres
adapter should be out of beta on 3.0 stable.
### How?
* Bumps `drizzle-orm` to `0.36.1` and `drizzle-kit` to `0.28.0` as we
need this change https://github.com/drizzle-team/drizzle-orm/pull/3141
* Uses its functions to achieve querying functionality, for example the
`near` operator works through `ST_DWithin` or `intersects` through
`ST_Intersects`.
* Removes MongoDB condition from all point field tests, but keeps for
SQLite

Adjust drizzle init for changes in drizzle 0.35.0
https://github.com/drizzle-team/drizzle-orm/releases/tag/0.35.0
The pool/connection should now be passed as the `client` arg when
initializing drizzle.
```ts
this.drizzle = drizzle({
client: this.poolOptions ? new VercelPool(this.poolOptions) : sql,
logger,
schema: this.schema,
})
```
This was causing an issue where running `payload migrate` on Vercel was
causing drizzle to attempt to `127.0.0.1:5432` instead of the specified
environment variable in the adapter 🤔
Fixes https://github.com/payloadcms/payload/issues/8752
Previously, trying to define a config like this:
```ts
{
type: 'text',
name: 'someText',
index: true,
},
{
type: 'array',
name: 'some',
index: true,
fields: [
{
type: 'text',
name: 'text',
index: true,
},
],
}
```
Lead to the error:
```
Warning We've found duplicated index name across public schema. Please rename your index in either the demonstration table or the table with the duplicated index name
```
Now, if we encounter duplicates, we increment the name like this:
`collection_some_text_idx`
`collection_some_text_1_idx`

Adds `createDatabase` method to Postgres adapters which can be used
either independently like this:
```ts
payload.db.createDatabase({
name: "some-database",
schemaName: "custom-schema"
})
```
Or
```ts
payload.db.createDatabase()
```
Which creates a database from the current configuration, this is used in
`connect` if `autoDatabaseCreate` is set to `true` (default).
You can disable this behaviour with:
```ts
postgresAdapter({ autoDatabaseCreate: false })
```
Example:

src="https://github.com/user-attachments/assets/8d08c79d-9672-454c-af0f-eb802f9dcd99">
Adds abillity to customize the generated Drizzle schema with
`beforeSchemaInit` and `afterSchemaInit`. Could be useful if you want to
preserve the existing database schema / override the generated one with
features that aren't supported from the Payload config.
## Docs:
### beforeSchemaInit
Runs before the schema is built. You can use this hook to extend your
database structure with tables that won't be managed by Payload.
```ts
import { postgresAdapter } from '@payloadcms/db-postgres'
import { integer, pgTable, serial } from 'drizzle-orm/pg-core'
postgresAdapter({
beforeSchemaInit: [
({ schema, adapter }) => {
return {
...schema,
tables: {
...schema.tables,
addedTable: pgTable('added_table', {
id: serial('id').notNull(),
}),
},
}
},
],
})
```
One use case is preserving your existing database structure when
migrating to Payload. By default, Payload drops the current database
schema, which may not be desirable in this scenario.
To quickly generate the Drizzle schema from your database you can use
[Drizzle
Introspection](https://orm.drizzle.team/kit-docs/commands#introspect--pull)
You should get the `schema.ts` file which may look like this:
```ts
import { pgTable, uniqueIndex, serial, varchar, text } from 'drizzle-orm/pg-core'
export const users = pgTable('users', {
id: serial('id').primaryKey(),
fullName: text('full_name'),
phone: varchar('phone', { length: 256 }),
})
export const countries = pgTable(
'countries',
{
id: serial('id').primaryKey(),
name: varchar('name', { length: 256 }),
},
(countries) => {
return {
nameIndex: uniqueIndex('name_idx').on(countries.name),
}
},
)
```
You can import them into your config and append to the schema with the
`beforeSchemaInit` hook like this:
```ts
import { postgresAdapter } from '@payloadcms/db-postgres'
import { users, countries } from '../drizzle/schema'
postgresAdapter({
beforeSchemaInit: [
({ schema, adapter }) => {
return {
...schema,
tables: {
...schema.tables,
users,
countries
},
}
},
],
})
```
Make sure Payload doesn't overlap table names with its collections. For
example, if you already have a collection with slug "users", you should
either change the slug or `dbName` to change the table name for this
collection.
### afterSchemaInit
Runs after the Drizzle schema is built. You can use this hook to modify
the schema with features that aren't supported by Payload, or if you
want to add a column that you don't want to be in the Payload config.
To extend a table, Payload exposes `extendTable` utillity to the args.
You can refer to the [Drizzle
documentation](https://orm.drizzle.team/docs/sql-schema-declaration).
The following example adds the `extra_integer_column` column and a
composite index on `country` and `city` columns.
```ts
import { postgresAdapter } from '@payloadcms/db-postgres'
import { index, integer } from 'drizzle-orm/pg-core'
import { buildConfig } from 'payload'
export default buildConfig({
collections: [
{
slug: 'places',
fields: [
{
name: 'country',
type: 'text',
},
{
name: 'city',
type: 'text',
},
],
},
],
db: postgresAdapter({
afterSchemaInit: [
({ schema, extendTable, adapter }) => {
extendTable({
table: schema.tables.places,
columns: {
extraIntegerColumn: integer('extra_integer_column'),
},
extraConfig: (table) => ({
country_city_composite_index: index('country_city_composite_index').on(
table.country,
table.city,
),
}),
})
return schema
},
],
}),
})
```

Dedicated adapter for Vercel Postgres
- Uses the `@vercel/postgres` package under the hood.
- No `pg` dependency, speeds up invocation
- Includes refactoring all base postgres functionality into a
`BasePostgresAdapter` type, which will ease implementation of [other
adapters supported by
drizzle-orm](https://orm.drizzle.team/docs/get-started-postgresql)
## Usage
```ts
import { buildConfig } from 'payload'
import { vercelPostgresAdapter } from '@payloadcms/db-vercel-postgres'
export default buildConfig({
db: vercelPostgresAdapter({
pool: {
connectionString: process.env.DATABASE_URI,
},
}),
// ...rest of config
})
```
### Automatic Connection String Detection
Have Vercel automatically detect from environment variable (typically
`process.env.POSTGRES_URL`)
```ts
export default buildConfig({
db: postgresAdapter(),
// ...rest of config
})
```
Allow a compound index to be used for upload collections via a
`filenameCompoundIndex` field. Previously, `filename` was always treated
as unique.
Usage:
```ts
{
slug: 'upload-field',
upload: {
// Slugs to include in compound index
filenameCompoundIndex: ['filename', 'alt'],
},
}
```
## Description
Fixes#7492
In order to run createMigration, we need to read in the previous
snapshot file if one exists. When that snapshot was generated from an
older version of drizzle-kit, we have to first migrate it up match the
latest version for drizzle to generate the new migration. This change
adds in the call to check the version and migrate the snapshot if
needed.
## Description
Prior to this change, the `defaultValue` for fields have only been used
in the application layer of Payload. With this change, you get the added
benefit of having the database columns get the default also. This is
especially helpful when adding new columns to postgres with existing
data to avoid needing to write complex migrations. In MongoDB this
change applies the default to the Mongoose model which is useful when
calling payload.db.create() directly.
This only works for statically defined values.

## Description
### payload
- Removes calls to beginTransaction and commitTransaction from read
operations
### db-sqlite, db-postgres
- beginTransaction() options are passed through and used to create a
transaction
- declare module type adds beginTransaction with proper transaction
config args for postgres and sqlite
Fixes#7402
This fixes a regression from changes to the postgres migration template
that were incorrect. It also fixes other type errors for
`payload.db.drizzle` which needed to be declared for postgres to avoid
confusing it with Libsql for SQLite.
- Abstract shared sql code to a new drizzle package
- Adds sqlite package, not ready to publish until drizzle patches some
issues
- Add `transactionOptions` to allow customizing or disabling db
transactions
- Adds "experimental" label to the `schemaName` property until drizzle
patches an issue

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

await addDataAndFileToRequest({ request: req })
addLocalesToRequestFromData({ request: req })
// current
await addDataAndFileToRequest(req)
addLocalesToRequestFromData(req)

BREAKING: `ValidationError` now requires the `global` or `collection`
slug, as well as an `errors` property. The actual errors are no longer
at the top-level.
**BREAKING:**
- Type narrowing for `relationTo` props on filterOptions, relationship
fields and upload fields
- Type narrowing for arguments of lexical relationship, link and upload
features
# 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.

## Description
fixes#6630
# BREAKING CHANGES
This only applies to you if you using db-postgres and have created the
`v2-v3-relationships` migration released in
[v3.0.0-beta.39](https://github.com/payloadcms/payload/releases/tag/v3.0.0-beta.39)
from @payloadcms/db-postgres <= v3.0.0-beta.40.
### Steps to fix
- Delete the existing v2-v3-relationships migration file.
- If changes were made to your config since the previous migration was
made, you will need to revert those by checking out a previous commit in
your version control.
- Recreate the migration using `payload migrate:create --file
@payloadcms/db-postgres/relationships-v2-v3` to make the migration with
the snapshot .json file.
BREAKING CHANGE:
Moves `upload` field and `relationship` fields with `hasMany: false` &
`relationTo: string` from the many-to-many `_rels` join table to simple
columns. This only affects Postgres database users.
## TL;DR
We have dramatically simplified the storage of simple relationships in
relational databases to boost performance and align with more expected
relational paradigms. If you are using the beta Postgres adapter, and
you need to keep simple relationship data, you'll need to run a
migration script that we provide you.
### Background
For example, prior to this update, a collection of "posts" with a simple
`hasMany: false` and `relationTo: 'categories'` field would have a
`posts_rels` table where the category relations would be stored.
This was somewhat unnecessary as simple relations like this can be
expressed with a `category_id` column which is configured as a foreign
key. This also introduced added complexity for dealing directly with the
database if all you have are simple relations.
### Who needs to migrate
You need to migrate if you are using the beta Postgres database adapter
and any of the following applies to you.
- If you have versions enabled on any collection / global
- If you use the `upload` field

### We have a migration for you
Even though the Postgres adapter is in beta, we've prepared a predefined
migration that will work out of the box for you to migrate from an
earlier version of the adapter to the most recent version easily.
It makes the schema changes in step with actually moving the data from
the old locations to the new before adding any null constraints and
dropping the old columns and tables.
### How to migrate
The steps to preserve your data while making this update are as follows.
These steps are the same whether you are moving from Payload v2 to v3 or
a previous version of v3 beta to the most recent v3 beta.
**Important: during these steps, don't start the dev server unless you
have `push: false` set on your Postgres adapter.**
#### Step 1 - backup
Always back up your database before performing big changes, especially
in production cases.
#### Step 2 - create a pre-update migration
Before updating to new Payload and Postgres adapter versions, run
`payload migrate:create` without any other config changes to have a
prior snapshot of the schema from the previous adapter version
#### Step 3 - if you're migrating a dev DB, delete the dev `push` row
from your `payload_migrations` table
If you're migrating a dev database where you have the default setting to
push database changes directly to your DB, and you need to preserve data
in your development database, then you need to delete a `dev` migration
record from your database.
Connect directly to your database in any tool you'd like and delete the
dev push record from the `payload_migrations` table using the following
SQL statement:
```sql
DELETE FROM payload_migrations where batch = -1`
```
#### Step 4 - update Payload and Postgres versions to most recent
Update packages, making sure you have matching versions across all
`@payloadcms/*` and `payload` packages (including
`@payloadcms/db-postgres`)
#### Step 5 - create the predefined migration
Run the following command to create the predefined migration we've
provided:
```
payload migrate:create --file @payloadcms/db-postgres/relationships-v2-v3
```
#### Step 6 - migrate!
Run migrations with the following command:
```
payload migrate
```
Assuming the migration worked, you can proceed to commit this change and
distribute it to be run on all other environments.
Note that if two servers connect to the same database, only one should
be running migrations to avoid transaction conflicts.

## Description
Fixes an issue with creating versions when using custom DB names,
`uuid`, and drafts.

Co-authored-by: PatrikKozak <patrik@payloadcms.com>
When typing into the search input on the list view of a collection, the
`like` operator is used for id which causes an error for postgres. To
fix this we are sanitizing the `like` for number or uuid fields to
instead be an `equals` operator. An alternate solution would have been
to cast the ids to text `id::text` but this would have performence
implications on larger data sets.
