Alessio Gravili 67fb29b2a4 fix: reduce global DOM/Node type conflicts in server-only packages (#12737)
Currently, we globally enable both DOM and Node.js types. While this
mostly works, it can cause conflicts - particularly with `fetch`. For
example, TypeScript may incorrectly allow browser-only properties (like
`cache`) and reject valid Node.js ones like `dispatcher`.

This PR disables DOM types for server-only packages like payload,
ensuring Node-specific typings are applied. This caught a few instances
of incorrect fetch usage that were previously masked by overlapping DOM
types.

This is not a perfect solution - packages that contain both server and
client code (like richtext-lexical or next) will still suffer from this
issue. However, it's an improvement in cases where we can cleanly
separate server and client types, like for the `payload` package which
is server-only.

## Use-case

This change enables https://github.com/payloadcms/payload/pull/12622 to
explore using node-native fetch + `dispatcher`, instead of `node-fetch`
+ `agent`.

Currently, it will incorrectly report that `dispatcher` is not a valid
property for node-native fetch

Payload Cloud Storage Plugin

This repository contains the officially supported Payload Cloud Storage plugin. It extends Payload to allow you to store all uploaded media in third-party permanent storage.

NOTE: If you are using Payload 3.0 and one of the following storage services, you should use one of following packages instead of this one:

Service Package
Vercel Blob @payloadcms/storage-vercel-blob
AWS S3 @payloadcms/storage-s3
Azure @payloadcms/storage-azure
Google Cloud Storage @payloadcms/storage-gcs

This package is now best used for implementing custom storage solutions or third-party storage services that do not have @payloadcms/storage-* packages.

Installation

pnpm add @payloadcms/plugin-cloud-storage

Usage

import { buildConfig } from 'payload'
import { cloudStoragePlugin } from '@payloadcms/plugin-cloud-storage'

export default buildConfig({
  plugins: [
    cloudStoragePlugin({
      collections: {
        'my-collection-slug': {
          adapter: theAdapterToUse, // see docs for the adapter you want to use
        },
      },
    }),
  ],
  // The rest of your config goes here
})

Conditionally Enabling/Disabling

The proper way to conditionally enable/disable this plugin is to use the enabled property.

cloudStoragePlugin({
  enabled: process.env.MY_CONDITION === 'true',
  collections: {
    'my-collection-slug': {
      adapter: theAdapterToUse, // see docs for the adapter you want to use
    },
  },
}),

If the code is included in any way in your config but conditionally disabled in another fashion, you may run into issues such as Webpack Build Error: Can't Resolve 'fs' and 'stream' or similar because the plugin must be run at all times in order to properly extend the webpack config.

Features

Adapter-based Implementation

This plugin supports the following adapters:

However, you can create your own adapter for any third-party service you would like to use.

All adapters are implemented dev directory's Payload Config. See this file for examples.

Plugin options

This plugin is configurable to work across many different Payload collections. A * denotes that the property is required.

Option Type Description
collections * Record<string, CollectionOptions> Object with keys set to the slug of collections you want to enable the plugin for, and values set to collection-specific options.
enabled boolean to conditionally enable/disable plugin. Default: true.

Collection-specific options:

Option Type Description
adapter * Adapter Pass in the adapter that you'd like to use for this collection. You can also set this field to null for local development if you'd like to bypass cloud storage in certain scenarios and use local storage.
disableLocalStorage boolean Choose to disable local storage on this collection. Defaults to true.
disablePayloadAccessControl true Set to true to disable Payload's access control. More
prefix string Set to media/images to upload files inside media/images folder in the bucket.
generateFileURL GenerateFileURL Override the generated file URL with one that you create.

Payload Access Control

Payload ships with access control that runs even on statically served files. The same read access control property on your upload-enabled collections is used, and it allows you to restrict who can request your uploaded files.

To preserve this feature, by default, this plugin keeps all file URLs exactly the same. Your file URLs won't be updated to point directly to your cloud storage source, as in that case, Payload's access control will be completely bypassed and you would need public readability on your cloud-hosted files.

Instead, all uploads will still be reached from the default /:collectionSlug/file/:filename path. This plugin will "pass through" all files that are hosted on your third-party cloud service—with the added benefit of keeping your existing access control in place.

If this does not apply to you (your upload collection has read: () => true or similar) you can disable this functionality by setting disablePayloadAccessControl to true. When this setting is in place, this plugin will update your file URLs to point directly to your cloud host.
