JavaScript How to set Websocket to communicate with a client and a server-sent-events server? websocket communicate with each other,websocket communication

I need to build a 2 way communication between a browser and an REST API service.

One of the most complex thing I am facing is checking the API for updates every second.

I have two types of communication

  1. Browser passes data and a command to the API. The API executes the command and returns a respond.
  2. Check the API every second, update the user's cache, send the cache content of the cache to the browser.

I tried different techniques to handle this, but none of them worked good and all were not scale-able.

Here are some techniques I tried

  1. Call the API every second using setInterval() function in Javascript.
  2. Server-Sent-Events (SSE)
  3. Call the API every second using setInterval() function inside a ShardWorker.

I am hoping I can do this communication using a WebSocket and node.js.

How can WebSocket handler both communication types listed above?
