How do I run a web service with websockets on app platform?

I’m trying to run a Node.js app that exposes a websocket server to the internet. I am unable to connect to my websocket server on the HTTP port that the app platform app has me specify.

Services that you run on the App Platform are exposed via app domains on port 443/HTTPS. So you should also use the wss:// scheme when connecting. This is not necessarily the same port as you would specify that your service is listening on internally.

I have a sample nodejs repo that uses websockets and can be forked + deployed to the App Platform without any changes if that helps as a reference: https://github.com/snormore/sample-websocket

Hey,

Services within the same application share a private network with one another. You should be able to communicate between the components using internal HTTP. Components can be referenced by their component name, for example: if you have two services with an app, api, and web. The web service could make requests to http://api for internal communication.
