Does not work with Firefox

[jsarenik]

Testing with Firefox 71.0 connected to Google Chrome.

From Firefox to Chrome the message is sent, but shown twice on Chrome.
From Chrome to Firefox the message does not appear in Firefox.

Two Firefox (one of them in Private mode) do not show each other's messages at all.

@jsarenik Thanks for opening this issue! (I remembered you said in a comment before :D )

In my quick investigation, Firefox doesn't have WritableStream. I'll search for polyfill or consider whether WritableStream can be removed or not for this project.

I found WritableStreams are used only in the following for the same purpose. They seem to be easy to replace with code without WritableStream.

piping-chat-web/src/PipingChatter.ts

Lines 205 to 206 in 093d7a7

	// Wait for body being complete
	await res.body.pipeTo(new WritableStream({}));

Lines 430 to 431 in 093d7a7

	// Wait for body being complete
	await res.body.pipeTo(new WritableStream({}));
