Node.js WebSockets

This sample demonstrates how to use WebSockets on Cloud Run with Node.js.

• Node.js WebSockets sample for Cloud Run
  • Setup
  • Running locally
  • Deploying to Cloud Run
  • Running the tests

Setup

Before you can run or deploy the sample, you need to do the following:

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

2. Install dependencies:

   With npm:

   npm install

Running locally

With npm:

npm start

Deploying to Cloud Run

1. Create a Redis instance on Cloud Memorystore. Make sure to choose the VPC network you will use (default). After it’s created, note its IP address.

2. Create a VPC connector.. This will let our Cloud Run service connect to Redis over the VPC network. After it’s created, note its name.

3. Deploy to Cloud Run:

   export REGION=us-central1
   export CONNECTOR_NAME=<CONNECTOR>
   export REDISHOST=$(gcloud redis instances describe INSTANCE_ID --region REGION --format "value(host)")
   
   gcloud run deploy websockets --source . \
   --allow-unauthenticated \
   --region $REGION \
   --timeout 3600 \
   --vpc-connector $CONNECTOR_NAME \
   --set-env-vars REDISHOST=$REDISHOST
