Step by step

Create environment and install package

$ npx create-react-app demo  --template typescript
$ cd demo/
$ npm install
$ npm install @dannadori/bisenetv2-celebamask-worker-js
$ cp node_modules/\@tensorflow/tfjs-backend-wasm/dist/tfjs-backend-wasm.wasm public/

Add source image to public.

In this time, the name is "srcImage.jpg"

Edit src/App.tsx

Sample code is here.

import React from 'react';
import './App.css';
import { BisenetV2CelebAMaskWorkerManager, generateBisenetV2CelebAMaskDefaultConfig, generateDefaultBisenetV2CelebAMaskParams, createForegroundImage } from '@dannadori/bisenetv2-celebamask-worker-js'

class App extends React.Component{

  manager = new BisenetV2CelebAMaskWorkerManager()
  config = generateBisenetV2CelebAMaskDefaultConfig()
  params = generateDefaultBisenetV2CelebAMaskParams()

  srcCanvas = document.createElement("canvas")
  dstCanvas = document.createElement("canvas")

  componentDidMount = () =>{
    document.getRootNode().lastChild!.appendChild(this.srcCanvas)
    document.getRootNode().lastChild!.appendChild(this.dstCanvas)
    const srcImage = document.createElement("img")
    srcImage.onload = () =>{
      this.manager.init(this.config).then(()=>{
        this.srcCanvas.getContext("2d")!.drawImage(
          srcImage, 0, 0, this.srcCanvas.width, this.dstCanvas.height)
        return this.manager.predict(this.srcCanvas, this.params)
      }).then((res)=>{
        console.log(res)
        const foreground = createForegroundImage(this.srcCanvas, res)
        this.dstCanvas.getContext("2d")!.putImageData(foreground, 0, 0)
      })
    }
    srcImage.src = "./srcImage.jpg"
  }

  render = ()=>{
    return (
      <div className="App">
      </div>
    );
  }
}

export default App;
