• Added support of JavaScript-based implementation (based on zlib) of Compression Streams API (see https://github.com/gildas-lormeau/zlib-streams-ts) as an alternative to the default WASM-based implementation. See the new exports property in the package.json file and files in the /dist folder, JavaScript-based implementations are suffixed with -native (e.g. ./index-native.js).
• Fixed malloc error in environments not fully supporting WASM (see #605)

New in version 2.8

1. WebAssembly Integration

• Replaced JavaScript compression and decompression implementation with WebAssembly zlib module (https://github.com/gildas-lormeau/zlib-streams. This improves security and performance when native CompressionStream and DecompressionStream APIs are not used (for example, when using custom compression levels or decompressing deflate64 data) or unavailable.
• Added the wasmURI configuration property to provide the module URI if necessary (for example, when the CSP blocks data URIs).

2. Deflate64 Decompression Support

• Added support of proprietary Deflate64 decompression algorithm which can be used by Windows when compressing large files (see #517)

3. Simplified Configuration

• Replaced the complex workerScripts configuration with a single workerURI property, making it easier to set up web workers.
• Default values for workerURI and wasmURI are provided, reducing the need for manual configuration when building code.

4. Improved Type Safety and Clarity

• Refined TypeScript definitions, including clearer distinctions between DirectoryEntry and FileEntry.
• Deprecated and removed legacy APIs and classes, streamlining the library for current use cases.

Breaking Changes

1. Worker Configuration Changes:

• The workerScripts property in the configuration was removed and replaced with workerURI (and wasmURI for the WASM module).

2. Stream Implementation Updates:

• The Deflate and Inflate properties in the configuration were removed and replaced with CompressionStream and DecompressionStream.

3. Deprecated Classes Removed:

• The deprecated classes SplitZipReader and SplitZipWriter were removed.

4. Event-Based Codec Support Removed:

• Interfaces and classes related to event-based codecs, such as EventBasedZipLibrary, initShimAsyncCodec, and EventBasedCodec were removed.

5. Entry Metadata Changes in index.d.ts:

• The directory property was removed from EntryMetaData and moved to DirectoryEntry and FileEntry interfaces.

What's Changed in v2.8.2

• Fix edge cases of uncompressed size check by @0f-0b in #600

What's Changed

• fix: type of Uint8ArrayWriter by @targos in #594

New Contributors

• @targos made their first contribution in #594

Full Changelog: v2.7.72...v2.7.73

• Fixed regression when using zip.js in Node < 21.2 with the option useCompressionStream not explicitly set to false (Node.js does not support the deflate-raw format of the CompressionStream API in version < 21.2)
• Removed useless files from the JSR repository

• Improved security in ZipReader by:
  • adding the checkOverlappingEntry and checkOverlappingEntryOnly options (false by default) to detect potential non-recursive zip-bombs (e.g. "A better zip bomb"), more info here: #587 (comment)
  • making sure that the output size of the decompressed entry data matches the expected size exactly
• Fixed URLString type in the type definition file
• Updated dev dependencies

• Fixed bug in Data64URIWriter when writing small succeeding amounts of data (see #588)
• Improved security when uncompressing ZIP files. ZipReader will trigger an error as soon as the output size of an entry exceeds the expected "uncompressed size" defined in the central directory (see #587)

• Ensure the compressed size, the uncompressed size, and the CRC2 checksum are written in the local header if the data descriptor is not used (see #585)

Fixed regression introduced in version 2.7.65 when using HttpRangeReader with ZipWriter#add() (see #586)
