如何在firebase中实现这个.htaccess？

{
  "hosting": {
    "public": "public",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ],
    "rewrites": [
      {
        "source": "/api/**",
        "function": "apiProxy"
      },
      {
        "source": "**",
        "destination": "/index.html"
      }
    ]
  },
  "functions": {
    "apiProxy": {
      "runtime": "nodejs12",
      "handler": "proxy.handler"
    }
  }
}

const { createProxyMiddleware } = require('http-proxy-middleware');

module.exports = function (req, res) {
  const targetUrl = 'https://your-target-server.com/api';
  const proxy = createProxyMiddleware({ target: targetUrl, changeOrigin: true });

  proxy(req, res, function (err) {
    if (err) {
      res.status(500).send('Error occurred while proxying the request');
    }
  });
};

npm install http-proxy-mirtual

firebase deploy
