Examples

https://stackblitz.com/edit/vitejs-vite-ey9bl2?file=src%2FApp.tsx

import { Component, createSignal } from "solid-js";
import { Circle, Layer, Rect, Stage } from "solid-konva";

const App: Component = () => {
  const [x, setX] = createSignal(50);
  const [y, setY] = createSignal(50);

  return (
    <div>
      <input
        type="range"
        min={0}
        max={1000}
        value={x()}
        onInput={(e) => setX(e.currentTarget.valueAsNumber)}
      />
      <input
        type="range"
        min={0}
        max={1000}
        value={y()}
        onInput={(e) => setY(e.currentTarget.valueAsNumber)}
      />
      <Stage style={{ height: "100vh" }}>
        <Layer>
          <Circle
            {...{
              x: x(),
              y: y(),
              width: 100,
              height: 50,
              fill: "red",
              stroke: "black",
              strokeWidth: 4,
            }}
          />
          <Rect
            {...{
              x: x() * 2,
              y: y() * 2,
              width: 100,
              height: 50,
              fill: "red",
              stroke: "black",
              strokeWidth: 4,
              draggable: true,
            }}
          />
        </Layer>
      </Stage>
    </div>
  );
};

export default App;

Working with Image

Currently experimental have added createImageSignal to load an image from src string or base64 content.

On error it currently displays a red pixel. On loading it should use a transparent pixel.

import { Component, createSignal } from "solid-js";
import { Image2D, createImageSignal, Layer, Stage } from "solid-konva";

const App: Component = () => {
  const [image, setImageSrc] = createImageSignal();
  setImageSrc('https://picsum.photos/200/300');

  return (
    <>
      <Stage style={{ height: "100vh" }}>
      <Layer>
      <Image2D
      {...{
        x: rectPos().x + 200,
        y: rectPos().y + 200,
        image: image(),
        width: image()?.nativeWidth, // Optional?
        height: image()?.nativeHeight, // Optional?
      }} />
    </Layer>
    </Stage>
    </>
  );
};

pnpm dev or npm dev or npm start

Runs the app in the development mode. Open http://localhost:3000 to view it in the browser.

The page will reload if you make edits.

pnpm build or npm run build

Builds the app for production to the dist folder. It correctly bundles Solid in production mode and optimizes the build for the best performance.

The build is minified and the filenames include the hashes. Your app is ready to be deployed!

Deployment

You can deploy the dist folder to any static host provider (netlify, surge, now, etc.)
