Node.js websockets sample for Google App Engine

This sample demonstrates how to use websockets on Google App Engine Managed VMs with Node.js.

Note: Secure WebSockets are currently not supported by Managed VMs. WebSockets will only work if you load your page over HTTP (not HTTPS).

To use Secure WebSockets now, you can launch a VM on Google Compute Engine using a custom image where you have added SSL support for WebSockets.

Refer to the appengine/README.md file for instructions on running and deploying.

Setup

Before you can run or deploy the sample, you will need to create a new firewall rule to allow traffic on port 65080. This port will be used for websocket connections. You can do this with the Google Cloud SDK with the following command:

gcloud compute firewall-rules create default-allow-websockets \
  --allow tcp:65080 \
  --target-tags websocket \
  --description "Allow websocket traffic on port 65080"
