A couple weeks ago, I was asked to create a simple communicator for one of our clients. I had to dig deeper into the topic and I decided to create a very basic proof of concept, without all the shiny features, a straightforward chat application that implements “one-to-many” communication. I wanted to use technology that I already knew, so client application was created in Vue.js using Vue-cli 3 and server was created in Node.js. For development purpose I used Express web server, which is flexible and fast, just enough for MVP. What I’d like to show you is how fast we can achieve this goal in terms of configuration and coding.
