Prakash 6af3667c8c chore(deps): upgrade jsdom 26→29 (migrate xhr-upload tests to MSW)
Bumps jsdom 26 → 29 across all packages' devDependencies, EXCEPT
@uppy/aws-s3 (left at 26 — that plugin is being rewritten and its deps are
handled separately on the rewrite branch).

jsdom 29 changed its XMLHttpRequest internals so that nock — which patches
Node's http module — can no longer intercept XHR upload requests in the
jsdom-env unit tests, causing timeouts / spurious network errors. Fixed by
migrating @uppy/xhr-upload's unit tests from nock to MSW (msw/node
setupServer), which intercepts at the XMLHttpRequest layer and works across
jsdom versions. nock is dropped from @uppy/xhr-upload's devDependencies.

Verified: full test suite 23/23 green, typecheck 83/83, biome clean.

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.
