Not sure how to stream large amounts of data when the total size is unknown.

I can see in examples and documentation how to stream large amounts of data when the total amount is known - use tryEnd and onWritable. But tryEnd will close the stream when the total amount is reached and I need to start sending data down before I know what the total size will be. It would be useful if there was a tryWrite that worked similarly but didn't require knowing the total size right away.

tryWrite is a good opinion, yes we should have it, but so far we only have write. You can stream small chunks with write of, let's say 4kb a time, checking the return of write, stopping when full, continuing in onWritable.

So write will use Transfer-Encoding: chunked and you can write as much you want until calling end
