1.umi创建工程 https://umijs.org/zh-CN/docs/getting-started；止于启动项目yarn start；不添加layout:{}

2.添加antd，react-unity-webgl (均为最新版本)；package.json 

{
  "private": true,
  "scripts": {
    "start": "umi dev",
    "build": "umi build",
    "postinstall": "umi generate tmp",
    "prettier": "prettier --write '**/*.{js,jsx,tsx,ts,less,md,json}'",
    "test": "umi-test",
    "test:coverage": "umi-test --coverage"
  },
  "gitHooks": {
    "pre-commit": "lint-staged"
  },
  "lint-staged": {
    "*.{js,jsx,less,md,json}": [
      "prettier --write"
    ],
    "*.ts?(x)": [
      "prettier --parser=typescript --write"
    ]
  },
  "dependencies": {
    "@ant-design/pro-layout": "^6.5.0",
    "@umijs/preset-react": "1.x",
    "antd": "4.13.0",
    "react-unity-webgl": "^8.1.1",
    "umi": "^3.3.9"
  },
  "devDependencies": {
    "@types/react": "^17.0.0",
    "@types/react-dom": "^17.0.0",
    "@umijs/test": "^3.3.9",
    "lint-staged": "^10.0.7",
    "prettier": "^2.2.0",
    "react": "17.x",
    "react-dom": "17.x",
    "typescript": "^4.1.2",
    "yorkie": "^2.0.0"
  }
}

3.创建public文件夹，拷贝unity webgl build输出包（只保留build内文件）；修改index.tsx

import styles from './index.less';
import {Button} from 'antd/es';
import Unity,{UnityContext} from 'react-unity-webgl';

const unityContext = new UnityContext({
  loaderUrl: "build/build.loader.js",
  dataUrl: "build/build.data",
  frameworkUrl: "build/build.framework.js",
  codeUrl: "build/build.wasm",
});

export default function IndexPage() {
  return (
    <div>
      <h1 className={styles.title}>Page index</h1>
      <Button>Hit me</Button>
      <Unity width="100%" height="100%" unityContext={unityContext} />
    </div>
  );
}

4. yarn start 正常运行；暂时比较顺利；（dva基本不跟新，使用dva引入antd，编译失败无法运行<_<）!
