v3.1.1

• 🐛 Fix compatibility with TypeScript's DOM types for ReadableStream and TransformStream (#85, #86)

v3.1.0

• 🚀 Calling ReadableStream.tee() on a readable byte stream now returns two readable byte streams. (#81)
• 🚀 Add WritableStreamDefaultController.signal and .abortReason. (#81)
  • .signal requires a global AbortController constructor to be available. If necessary, use a polyfill.
• 🐛 Make sure streams created with a different version of the polyfill do not pass the brand checks. (#75, #77)
• 👓 Align with spec version cada812 (#79, #81)

v3.0.3

• 💅 Change Promise<void> to Promise<undefined> in TypeScript type definitions (#72)
• 🐛 Fix ReadableStream.tee() resolving its cancel() promise too early (#73)
• 👓 Align with spec version 6762cdb (#73)

v3.0.2

• 👓 Align with spec version 200c971 (#69)

v3.0.1

• 📝 Add documentation to type definitions (#62)
• 👓 Align with spec version 6cd5e81 (#63)
• 🐛 Fix an issue where the polyfill could throw an error when resolving/rejecting reader.closed when it was already resolved/rejected (#66, #67)

v3.0.0

• 💥 Align with spec version 62fe4c8 (#52, #57, #59)
  This includes the following breaking changes:
  • All classes are now exposed globally. Concretely, this adds the following classes:
    • ReadableStreamDefaultController
    • ReadableByteStreamController
    • ReadableStreamBYOBRequest
    • ReadableStreamDefaultReader
    • ReadableStreamBYOBReader
    • WritableStreamDefaultController
    • WritableStreamDefaultWriter
    • TransformStreamDefaultController
  • ReadableStream.getIterator() is renamed to ReadableStream.values()
  • ReadableByteStreamController.byobRequest can be null (instead of undefined) if there is no current BYOB request.
  • ReadableStreamBYOBRequest.view can be null (instead of undefined) if the BYOB request has already been responded to.
  • Constructors and methods have stricter type checking for object arguments. For example, new ReadableStream(null) would previously behave like new ReadableStream({}), but now it throws a TypeError instead.
  • Some constructors and methods may throw slightly different errors when given invalid arguments.
  • Various byte-stream-related APIs now prohibit zero-length views or buffers.
  • The async iterator of a ReadableStream now behaves more like an async generator, e.g. returning promises fulfilled with { value: undefined, done: true } after return()ing the iterator, instead of returning a rejected promise.
• 💥 Updated TypeScript types to align with new specification (#60)
  While these are technically breaking changes, you should only be affected if you manually reference these types from your code.
  • PipeOptions is renamed to StreamPipeOptions
  • ReadResult is replaced by ReadableStreamDefaultReadResult and ReadableStreamBYOBReadResult
  • ReadableStreamDefaultControllerCallback is replaced by UnderlyingSourceStartCallback and UnderlyingSourcePullCallback
  • ReadableByteStreamControllerCallback is replaced by UnderlyingByteSourceStartCallback and UnderlyingByteSourcePullCallback
  • ReadableStreamErrorCallback is renamed to UnderlyingSourceCancelCallback
  • WritableStreamDefaultControllerStartCallback is renamed to UnderlyingSinkStartCallback
  • WritableStreamDefaultControllerWriteCallback is renamed to UnderlyingSinkWriteCallback
  • WritableStreamDefaultControllerCloseCallback is renamed to UnderlyingSinkCloseCallback
  • WritableStreamErrorCallback is renamed to UnderlyingSinkAbortCallback
  • TransformStreamDefaultControllerCallback is replaced by TransformerStartCallback and TransformerFlushCallback
  • TransformStreamDefaultControllerTransformCallback is renamed to TransformerTransformCallback

v2.1.1

v2.1.0

• 👓 Align with spec version ed00d2f (#43, #44)
• 🏠 Down-level type definitions for older TypeScript versions. (#41)

v2.0.6

• 🐛 Fix type definitions to be compatible with TypeScript 3.3 and lower. (#39, #40)

v2.0.5

• 👓 Align with spec version ae5e0cb (#33)
• 🐛 Fix support for non-browser environments, such as Node.
  • Accept polyfilled AbortSignals. (#36)
  • Polyfill DOMException if necessary. (#37)
