Any idea of how to create a socket in Ionic React mobile App.Im trying to create a socket and send the data/info to an IOT device but it looks imposible.I tried with these plugins but they gives diferent errors:

With the first link i get this error:image of the error

With the second one i get: Uncaught SyntaxError: Unexpected token '!'
