@uppy/upgrade devdeps v2 (#6318)
AI disclaimer : AI used

## Changes
- **jsdom 26 → 29** across all packages' devDependencies —
**except`@uppy/aws-s3`** (left at 26; that plugin is being rewritten and
its deps are handled on the rewrite branch).
- **`@uppy/xhr-upload` unit tests migrated from nock to MSW**, and
`nock` dropped from its devDependencies.
  ## Why the test migration was needed
jsdom **28** overhauled resource loading so `XMLHttpRequest` now goes
through jsdom's internal (undici-based) fetch instead of Node's `http`
module ([jsdom 28 release
notes](https://github.com/jsdom/jsdom/releases/tag/28.0.0)).
nock intercepts at the Node `http` / `http.ClientRequest` layer ([nock
README](https://github.com/nock/nock)), so it can no longer see uppy's
upload requests — the mocked responses never arrive and the tests time
out. (This is the long-standing nock + jsdom XHR incompatibility:
[nock#518](https://github.com/nock/nock/issues/518).)

The Compressor plugin for Uppy optimizes images (JPEG, PNG, WEBP), saving on average up to 60% in size (roughly 18 MB for 10 images). It uses Compressor.js.

Uppy is being developed by the folks at Transloadit, a versatile file encoding service.

Example

import Uppy from '@uppy/core'
import Compressor from '@uppy/compressor'

const uppy = new Uppy()
uppy.use(Compressor)

Installation

npm install @uppy/compressor

We recommend installing from yarn or npm, and then using a module bundler such as Parcel, Vite or Webpack.

Alternatively, you can also use this plugin in a pre-built bundle from Transloadits CDN: Smart CDN. In that case Uppy will attach itself to the global window.Uppy object. See the main Uppy documentation for instructions.

Documentation

Documentation for this plugin can be found on the Uppy website.
