rewrite /path to root domain(/) for Single page application with any method

[ajaysourcedigital]

I am trying to map domain.com to domain.com/#/api. But it always routes back to home page. Anything I can do here to fix this ?

  "hosting": {
    "public": "public",
    "ignore": [
      "firebase.json",
      "**/.*",
      "**/node_modules/**"
    ],
    "rewrites": [
      {
        "source": "**",
        "destination": "/#/api"
      }
    ]
  }
}
