### What?
Adds `populate` property to Local API and REST API operations that can
be used to specify `select` for a specific collection when it's
populated
```ts
const result = await payload.findByID({
populate: {
// type safe if you have generated types
posts: {
text: true,
},
},
collection: 'pages',
depth: 1,
id: aboutPage.id,
})
result.relatedPost // only has text and id properties
```
```ts
fetch('https://localhost:3000/api/pages?populate[posts][text]=true') // highlight-line
.then((res) => res.json())
.then((data) => console.log(data))
```
It also overrides
[`defaultPopulate`](https://github.com/payloadcms/payload/pull/8934)
Ensures `defaultPopulate` doesn't affect GraphQL.
### How?
Implements the property for all operations that have the `depth`
argument.
### What?
I noticed a spelling error in the banner of the beta docs and decided I
could save everyone some time by *running the entirety of the beta docs*
through a spellchecker.
### Why?
To fix many spelling and formatting mistakes at once.
### How?
By enabling `edit mode` in my browser and letting the built-in
spellchecker perform its magic (and changing _only_ where it made
sense).
~~Ironically, the original spelling mistake that inspired me to do this
remains unchanged as that is a part of the website repo. [PR for that is
here](https://github.com/payloadcms/website/pull/388).~~
### What?
Adds `defaultPopulate` property to collection config that allows to
specify which fields to select when the collection is populated from
another document.
```ts
import type { CollectionConfig } from 'payload'
// The TSlug generic can be passed to have type safety for `defaultPopulate`.
// If avoided, the `defaultPopulate` type resolves to `SelectType`.
export const Pages: CollectionConfig<'pages'> = {
slug: 'pages',
// I need only slug, NOT the WHOLE CONTENT!
defaultPopulate: {
slug: true,
},
fields: [
{
name: 'slug',
type: 'text',
required: true,
},
],
}
```
### Why?
This is essential for example in case of links. You don't need the whole
document, which can contain large data but only the `slug`.
### How?
Implements `defaultPopulate` when populating relationships, including
inside of lexical / slate rich text fields.
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
