Here's the function code, I kept it as small as possible: https://github.com/verydanny/hooks/blob/main/hooks/hello-world/src/main.js
I reproduced my code using open-runtime - node-21.0 and had no issues rendering content on the page, and no hangups. I did this because I thought the issue was with open-runtime somewhere.
When using Appwrite with node-21.0, it hangs indefinitely and shows the following error in the console:
openruntimes-executor |
openruntimes-executor | Warning: Undefined array key "listening" in /usr/local/app/http.php on line 1023
openruntimes-executor |
openruntimes-executor | Warning: fsockopen(): Unable to connect to 6666003e27327:3000 (Connection refused) in /usr/local/src/Executor/Validator/TCP.php on line 45

I tracked the issue down to Readable.from(). Basically, with Appwrite, I can only send a Stream if it's a non-text MIME format, but as soon as it's JSON, HTML, or anything text-based it makes Appwrite hang forever.
This shouldn't be the case because html/txt should be streamable as well. I'm trying to build a mini router for functions, and it adds complexity and decreases performance if I have to check every file's MIME format and do response.text() for everything that's non-binary data.
Buffer.from works, but that would make the memory usage go up like crazy depending on the file being sent.
TL;DR
Developers are experiencing issues with Appwrite runtime not supporting Stream, unlike open-runtime. The problem seems to be related to the requirement of a `Content-Length` header, which shouldn't be necessary. An error message is shown when using Appwrite with `node-21.0`, leading to indefinite hangups. The issue is traced back to `Readable.from()`, where only non-text MIME formats can be sent as a Stream with Appwrite. Using `Buffer.from` works but can drastically increase memory usage. The ideal condition is for text-based MIME formats like HTML/txt to be streamable as well in Appwrite.
