In fact, GridFSWriteStream's write method defines the first argument as Buffer whereas NodeJS.ReadableStream defines the first argument for its pipe-target's write method as Uint8Array | string. ReadableByteStreamController is for byte-oriented ReadableStreams. An implementation of the WHATWG Streams Standard. data from this is written in to transform.writable, Returns a pair of new instances to which this The writableStream.locked property is false by default, and is Readable Streams in node supports async iterators, getFilesFromPath works in Javascript but not in Typescript. By the way the example written in the [ upgrade-to-4 document|https://github.com/mongodb/node-mongodb-native/blob/4.0/docs/CHANGES_4.0.0.md] is written in the exact same way as my code and this does not compile.

This Streams API interface represents a readable stream of byte data. closed. This does actually run without problems (when I suppress the TS error) but Typescript would not let me compile it. and potentially transformed, before being pushed into the ReadableStream's implementation for ReadableStreams that are not byte-oriented. to your account, Search Terms: The utility consumer functions provide common options for consuming ReadableStream's data. pipeline is configured, transform.readable is returned.
