## WebSockets client

### In production

In your production system, you probably have a frontend created with a modern framework like React, Vue.js or Angular.

And to communicate using WebSockets with your backend you would probably use your frontend's utilities.

During the development of a plugin we would want to make it easy for a developer to create a plugin which means we would allow the direct use of a POM to state the dependencies of a given plugin and any tooling we created would be responsible for turning the dependency information in the POM into plugin metadata which described the dependencies of the plugin.
