How do I import the SockJS client into a Javascript Project

[AwesomeDude091]

I am working on a javascript project and cannot seem to be able to load the client SockJS object from its NPM sockjs-client counterpart.
I run yarn add sockjs-client and proceed to write import SockJS at which point my IDE (IntelliJ Ultimate) tells me sockjs does not exisit. Any help is much appreciated AwesomeDude091
