Uploading an Experiment Written in JavaScript, Not on PsychoPY

OS (e.g. Win10):
PsychoPy version (e.g. 1.84.x):
Standard Standalone? (y/n) If not then what?:

Hello,

I have designed an experiment using JavaScript. However, the experiment is not designed using PsychoPY or any online platform. Do you know where I can upload it for online participant recruitment? Is it possible to use Pavlovia directly without connecting it to PsychoPY?

How does it save data? If you just need a server (possibly with a mySQL database) then I might be willing to host it.
