How to enable type checking in watch mode when using node server

[michaelxiacs]

{
  "name": "node",
  "type": "module",
  "scripts": {
    "dev": "tsc & tsx watch src/index.ts"
  },
  "dependencies": {
    "@hono/node-server": "^1.13.8",
    "hono": "^4.6.20"
  },
  "devDependencies": {
    "@types/node": "^20.11.17",
    "tsx": "^4.7.1"
  }
}

When I run npm run dev, it only does type checking at the start, watch mode doesn't perform type checking. How can I perform type checking in watch mode?
