Evaluate:Microservice Architecture with WebSocket APIs

Create a new WebSocket API

In the API Gateway console, choose Create API, New API.

Under Choose the protocol, choose WebSocket.

For API name, enter My Chat API.

For Route Selection Expression, enter $request.body.action.

Enter a description if you’d like and click Create API.

The attribute described by the Route Selection Expression value should be present in every message that a client sends to the API. Here’s one example of a request message:

DDB.scan(scanParams, function (err, data) {
    // some code omitted for brevity
   var apigwManagementApi = new AWS.ApiGatewayManagementApi({
      apiVersion: "2018-11-29",
      endpoint: event.requestContext.domainName " /" + event.requestContext.stage
   });
    var postParams = {
        data: JSON.parse(event.body).data
    };
    let callbackArray = data.Items.map( async(el) => { ... });
    Promise.all(callbackArray);
    // some code omitted for brevity
});
