QUESTION

Is AWS API Gateway websockets chat example fully asynchronous?

Asked 2019-Oct-10 at 12:59

I'm looking at AWS API Gateway websockets support, announced relatively recently -

https://aws.amazon.com/blogs/compute/announcing-websocket-apis-in-amazon-api-gateway/

They have a sample chat server example -

https://github.com/aws-samples/simple-websockets-chat-app/blob/master/sendmessage/app.js

which I have running, very nice.

It isn't called simple-websockets-chat-app for nothing :)

By reading the code, it does exactly what you are concerned about. Only one lambda instance will fire the message to all connections.

But it's a chat room, is it common to have thousands of users ?

It also looks as if it's working asynchronously, via use of async and await keywords, which I guess are Promises

Yes, it works in an asynchronous way, but the lambda will still execute until all messages have been sent.
