Implementing a Websocket Server using Ballerina
In a previous post I discussed about Websocket, its use and how applicable it’s today while comparing it with HTTP/2. In the same post I also showed a sample prototype chat application that utilize Websockets. The front end uses JavaScript and the server is implemented using Python.
In this post I’m going to use the same front-end application but the Websocket server is going to be implemented using Ballerina which is a general purpose programming language that makes integration programming easy. I wrote about why you should try out Ballerina if you are new to the language here.
Implementing the Websocket service in Ballerina
Ballerina support building network services natively. It doesn’t require any third party library for such service implementations. Let’s look at how can we implement a websocket service in Ballerina.
The websocket service code can be found below. Let’s try to understand what happens in this code.
