@fcanvas/worker
The plugin provides support for using fCanvas in WebWorker
This plugin needs to be integrated into both
mainstreamandWorker
If you just need simple operation and don't need to redraw many times directly or manipulate events you don't need this plugin

Install
bash
pnpm add fcanvas @fcanvas/worker
Usage
To use the power of WebWorker with fCanvas you first need to create a Stage on the main thread to receive signals from Worker:
then you just create another Stage in Worker and send it to thread and use fCanvas as usual:
ts
import Worker from "./worker?worker"
import { portToWorker } from "@fcanvas/worker"
const worker = new Worker()
const stage = new Stage().mount("#app")
portToWorker(worker, stage)
ts
import {
Circle,
computed,
Layer,
Stage,
useMouseIsPressed,
useMousePos
} from "fcanvas"
import { portToThread } from "@fcanvas/worker"
const stage = new Stage()
const layer = new Layer()
stage.add(layer)
const pos = useMousePos(layer)
const mouseIsPressed = useMouseIsPressed(layer)
const circle = new Circle({
x: computed(() => pos.mouseX),
y: computed(() => pos.mouseY),
radius: 50,
stroke: "#fff",
fill: computed(() => (mouseIsPressed.value ? "red" : "green"))
})
layer.add(circle)
portToThread(stage)
