express-ws communicate variables between front and back end

I am writing a script that checks a devices gyroscope axis's with JavaScript. I need to send a front-end javascript variable, that is updated frequently, sometimes up to a couple times a second, to a back-end node.js variable. I heard that this is doable with express-ws, but if that is not necessary, that would be better.

If it matters, my JS variables are formatted similar to:

x = -103
y = 50
z = -10

(x, y, z could be a negative or positive integer) Thanks!

Solution

  • Look into socket.send() and socket.emit().
