Is there a way to send data/events to JavaScript from Julia?

[Nufflee]

I know it's possible to send data from JavaScript to Julia using @bind and input events but could I do it the other way around? My goal is to write a little Julia library for drawing on an HTML5 Canvas but I need to be able to send events to JavaScript in order to do that.

This is not the other way around, it is exactly what @bind is for! #598

I may be missing something or not describing my problem well enough but I already saw that issue and what's being shown there is the opposite of what I need. They're binding a Julia array to a JS context so that data drawn on the canvas by the user can be transferred into the Julia array. What I need is transferring a drawing/data from a Julia array to the JS context and drawing it on the canvas, no user input involved.

It does seem like PlutoRunner.publish_to_js may be what I'm looking for but I haven't got a chance to try it out yet.

I see! in that case PlutoRunner.publish_to_js or just JSON.jl is what you want. Take a look at #1124 and the Javascript sample notebook inside Pluto
