Let’s start by building a Koa based HTTP server. For my use case, receiving updates from the server periodically, I will stick to SSE. You can check this post to see the difference between SSE and Websocket and make your own opinion of when to use one or the other. These incoming messages can be treated as Events + data inside the web page. With server-sent events, it’s possible for a server to send new data to a web page at any time, by pushing messages to the web page. Traditionally, a web page has to send a request to the server to receive new data that is, the page requests data from the server. However, if you just want to receive data from the server you can use Server Sent Events. Your first impulse may be using WebSockets. Open index.js file in routes folder and add following code.When you want to have real time updates on a web application, you can rely on old-fashioned periodic polling or try to use some push capable modern technology.
