dropzone 6.2.0

v6.2.0

on Node.js NPM

Minor Changes

• #2351 ee82380 Thanks @enyo! - addedfiles now reports the files found inside a dropped folder. It previously received e.dataTransfer.files, which holds the folder entries rather than their contents, so anyone counting dropped files got the wrong answer for folders.

  This changes when the event fires. Reading a folder is asynchronous, so on browsers that support folder drops — all of them — addedfiles is now emitted once the walk finishes, after the individual addedfile events, instead of synchronously at the end of the drop handler. Listeners still receive the event; only the timing moves.

  Also adds an emptyfolder event, emitted with the folder's path when a dropped folder turns out to contain nothing at all.

• #2348 f0697ee Thanks @enyo! - parallelChunkUploads: true now starts at most parallelUploads chunks at a time rather than every chunk of the file at once. Pass a number to set a different limit, or Infinity to restore the previous behaviour.

• #2349 8a8b449 Thanks @enyo! - Add resizeTransparencyFill, the color shown through transparent parts of a resized image. A transparent PNG resized to image/jpeg previously came out with black where it used to be see-through; set this to "#fff", or any CSS color, for a background instead. Defaults to null, which keeps the current behavior.

Patch Changes

• d3a9221 Thanks @enyo! - Reword the default dictMaxFilesExceeded message from "You can not upload any more files." to "You cannot upload any more files."

• #2350 9b5015b Thanks @enyo! - Give the hidden file input an aria-label, so accessibility auditors stop reporting it as an unlabelled input. This does not change anything for screen reader users: browsers leave visibility: hidden elements out of the accessibility tree entirely, and the .dz-button carrying dictDefaultMessage remains the control they interact with.

• #2352 b24f8cc Thanks @enyo! - Associate the hidden file input with its form. The input is appended to hiddenInputContainer (the body by default), so it sits outside the form it belongs to and several dropzones on one page produce indistinguishable inputs. It now carries a form attribute when the dropzone is a form, or sits inside one, and that form has an id. The input has no name, so this does not change what a native submit sends — but it does mean the input now appears in form.elements.

• 4e13aab Thanks @enyo! - Vendor just-extend into the source and drop the dependency. Dropzone now installs with no dependencies at all; the option merging behaviour is unchanged.
