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
