How to convert vercel to nginx rewrite rule

Ruriko

There's a script I want to use but its designed to be deployed on vercel which I don't want to use but I want to host it on my server since it's cheaper. I'm not familiar with vercel so how do I convert vercel rewrite to nginx rewrite rules? I can't find tools that can convert vercel to nginx but could only find apache to nginx. It would be helpful if someone can give me an example or convert it for me.

{
  "rewrites": [
    {
      "source": "/:__PREFIX(~|-|image)/:__PATH(.+)",
      "destination": "/api/image"
    },
    {
      "source": "/:__PREFIX(ajax|rpc|.+\\.php)/:__PATH*",
      "destination": "/api/http"
    }
  ],
  "headers": [
    {
      "source": "/(api|ajax|rpc|.+\\.php)(.*)",
      "headers": [
        {
          "key": "Access-Control-Allow-Origin",
          "value": "*"
        }
      ]
    }
  ]
}
