title: "Uppy 1.26: Dashboard “disabled”, per-file headers" date: 2021-02-26 author: arturi image: "https://uppy.io/images/blog/1.26/dashboard-disabled.jpg"

published: true

Uppy 1.26 brings a new disabled option for the Dashboad, ability to set headers per file with XHR Upload, and fixes for the Transloadit plugin.

Dashboard “Disabled”

You can now specify a disabled option for the Dashboard, in order to make it non-interactive and grayed out. Users won’t be able to click on buttons or drop files.

This is useful when you need to confitionally enable/disable file uploading or manipulation, based on a condition in your app.

Your browser does not support the video tag: https://uppy.io/images/blog/images/blog/1.26/dashboard-disabled-vs-enabled.mp4

This option can be set on init:

uppy.use(Dashboard, {
  disabled: true,
})

and via API:

const dashboard = uppy.getPlugin('Dashboard')
dashboard.setOptions({ disabled: true })

userNameInput.addEventListener('change', () => {
  dashboard.setOptions({ disabled: false })
})

See the docs.

XHR Upload Per File headers

@uppy/xhr-upload now accept a headers: (file) => {} function, so you can do:

uppy.use(XHRUpload, {
  headers: file => ({
    'authorization': `bearer ${global.userToken}`,
    'header-name': file.meta.someMetaValue,
  }),
})

to determine file-specific headers.

The function syntax for headers is only available if the bundle option is false (the default). bundle uploads share only one set of headers.

Build System Improvements

• build: set legacy-peer-deps for npm 7. We have some peerDependency mismatches in our install tree. In npm 6 this was OK (maybe reason for a warning) but in npm 7 they hard fail the install
• build: added npm version check (33e656cad3 / @goto-bus-stop)

Transloadit Plugin

• Fixed a case where the plugin used stale file data.
• Fixed polling fallback bugs.
• Url concatenation is now more robust.

Misc

• @uppy/companion: Docker tag release (#2771 / @kiloreux)
• @uppy/companion: Companion should respect previously set value for Accesss-Control-Allow-Methods (#2726 / @tim-kos, @mifi, @so-steve)
• @uppy/transloadit: fix polling fallback bugs (#2759 / @goto-bus-stop)
• @uppy/utils: added mp4 file type support — Safari 14.0 on Mac records audio using audio/mp4 MIME type which isn't currently recognised by Uppy (#2753 / @dominiceden)

See changelog for details.
