chmod

2.5.0:

• new: mode field in input objects can override the default POSIX file mode.

2.4.6:

• bugfix: the filename attribute in a Content-Disposition header is now parsed correctly
  • when it is not the last attribute in the header
  • and when it is the extended filename* attribute

2.4.5:

• bugfix: the output stream can now be transferred without breaking the central repository.

Error propagation

2.4.4:

• options argument was missing in makeZip type declaration

2.4.3:

• Cancelling the output stream will really cause an error in the source iterator

Unicode Filename Flag

2.4.2:

• Filenames can be flagged as UTF-8 using the EFS bit in the file header flags.
  • This is configurable with the new buffersAreUTF8 option.
• And it should help the Windows Zip utility read non-ASCII filenames correctly.

2.4.1:

• Cancelling the output stream will now cause an error in the source iterator.

Unicode Filename Flag (v1 branch)

1.6.2:

• Filenames can be flagged as UTF-8 using the EFS bit in the file header flags.
  • This is configurable with the new buffersAreUTF8 option.
• And it should help the Windows Zip utility read non-ASCII filenames correctly.

1.6.1:

• Cancelling the output stream will now cause an error in the source iterator.

No more WebAssembly (for now…)

2.4.0

• No more WASM for CRC32, JavaScript is faster now anyway.

Backporting recent improvements from v2

1.6.0

• No more WASM for CRC32, JavaScript is faster now anyway.
• Added type and exports to package.json so client-zip can run in Node.js.
• Remove trailing slashes from file names.
• Fixed filename extraction from a Response when its URL has a trailing slash.
• Fixed content-length prediction when some files have a length of zero (previously, this threw an error).

Empty folders, filename heuristics

2.3.0

• Fixed filename extraction from a Response when its URL has a trailing slash.
• Empty folders may be added to the archive with { name, lastModified? }.
  • Remove trailing slashes from file names and add one to folder names if needed.
• Also export makeZip which returns a ReadableStream without its Response wrapper.

Content-Length prediction

2.2.0 (with typing and empty file size bugs fixed in 2.2.2 and 2.2.1)

• Zip file size can now be predicted by the predictLength function before creating it.
• Added an options parameter to downloadZip.
  • options.length can be set to include a "Content-Length" header in the Response.
  • options.metadata can instead be given the same argument as predictLength, as a shortcut to compute and set the Content-Length.

Content-Length prediction (without Zip64)

1.5.0 (and a typing fix in 1.5.1)

• Zip file size can now be predicted by the predictLength function before creating it.
• Added an options parameter to downloadZip.
  • options.length can be set to include a "Content-Length" header in the Response.
  • options.metadata can instead be given the same argument as predictLength, as a shortcut to compute and set the Content-Length.
• The worker script now supports all the input types supported in the ES module, not only Responses.

Small files in big archives

2.0.1

• Fixed a bug where small files requiring a 64-bit offset (but not size) were corrupted.
• Never use 64-bit sizes in data descriptor for small files, even at large offsets.
