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

S3 Storage for Payload

This package provides a simple way to use S3 with Payload.

NOTE: This package removes the need to use @payloadcms/plugin-cloud-storage as was needed in Payload 2.x.

Installation

pnpm add @payloadcms/storage-s3

Usage

  • Configure the collections object to specify which collections should use the AWS S3 adapter. The slug must match one of your existing collection slugs.
  • The config object can be any S3ClientConfig object (from @aws-sdk/client-s3). This is highly dependent on your AWS setup. Check the AWS documentation for more information.
  • When enabled, this package will automatically set disableLocalStorage to true for each collection.
  • When deploying to Vercel, server uploads are limited with 4.5MB. Set clientUploads to true to do uploads directly on the client. You must allow CORS PUT method for the bucket to your website.
  • Configure signedDownloads (either globally of per-collection in collections) to use presigned URLs for files downloading. This can improve performance for large files (like videos) while still respecting your access control. Additionally, with signedDownloads.shouldUseSignedURL you can specify a condition whether Payload should use a presigned URL, if you want to use this feature only for specific files.
import { s3Storage } from '@payloadcms/storage-s3'
import { Media } from './collections/Media'
import { MediaWithPrefix } from './collections/MediaWithPrefix'

export default buildConfig({
  collections: [Media, MediaWithPrefix],
  plugins: [
    s3Storage({
      collections: {
        media: true,
        'media-with-prefix': {
          prefix,
        },
        'media-with-presigned-downloads': {
          // Filter only mp4 files
          signedDownloads: {
            shouldUseSignedURL: ({ collection, filename, req }) => {
              return filename.endsWith('.mp4')
            },
          },
        },
      },
      bucket: process.env.S3_BUCKET,
      config: {
        credentials: {
          accessKeyId: process.env.S3_ACCESS_KEY_ID,
          secretAccessKey: process.env.S3_SECRET_ACCESS_KEY,
        },
        region: process.env.S3_REGION,
        // ... Other S3 configuration
      },
    }),
  ],
