support fabricjs from react

fabricjs-react

Install

We'll need to install fabric, react and react-dom because are peer dependencies of this library if you haven't yet otherwise install only what you don't have:

npm install --save fabricjs-react fabric react react-dom

Usage

Take a look at sandbox: https://codesandbox.io/s/flamboyant-wind-ff3x8

import React from 'react'

import { FabricJSCanvas, useFabricJSEditor } from 'fabricjs-react'

const App = () => {
  const { editor, onReady } = useFabricJSEditor()
  const onAddCircle = () => {
    editor?.addCircle()
  }
  const onAddRectangle = () => {
    editor?.addRectangle()
  }

  return (
    <div>
      <button onClick={onAddCircle}>Add circle</button>
      <button onClick={onAddRectangle}>Add Rectangle</button>
      <FabricJSCanvas className="sample-canvas" onReady={onReady} />
    </div>
  )
}

export default App

Alternative use cases

Add image (#3)

For this case, you have to reference the FabricJS dependency to first load the image:

import { fabric } from 'fabric'; // this also installed on your project
import { useFabricJSEditor } from 'fabricjs-react';

const { selectedObjects, editor, onReady } = useFabricJSEditor();
useEffect(() => {
  fabric.Image.fromURL('my_image.png', function (oImg) {
    editor?.canvas.add(oImg);
  });
}, [fabric, editor])
...
