Response headers using static.json and React Router

[dcporter44]

I am trying to set a header in static.json on ONLY my index.html file using:

headers: { "/": { "Cache-Control": "no-store" } }

The header works successfully when I specifically go to "https://mywebsite.com/"
But if I go to "https://mywebsite.com/sign-in", the header is not there. This is because /sign-in is not an actual file in my project. It is a route generated by React router.

I know I can use "/**" instead of "/" in static.json, but I don't want to add this header to my .css, .js, fonts etc.

Is there functionality available in static.json to apply headers to only the HTML file, no matter the route?

Here is the entrity of my static.json file for reference:

{
  "root": "build/",
  "routes": {
    "/**": "index.html"
  },
  "https_only": true,
  "headers": {
    "/**": {
      "Strict-Transport-Security": "max-age=31557600",
      "X-Frame-Options": "SAMEORIGIN",
      "X-Content-Type-Options": "nosniff",
      "X-XSS-Protection": "1; mode=block"
    },
    "/": {
      "Cache-Control": "no-store"
    }
  }
}

You can add additional rules to override your default.

{
  "root": "public/",
  "headers": {
    "/**": {
      "Cache-Control": "public, max-age=0, must-revalidate"
    },
    "/**.css": {
      "Cache-Control": "public, max-age=31536000, immutable"
    },
    "/**.js": {
      "Cache-Control": "public, max-age=31536000, immutable"
    },
    "/static/**": {
      "Cache-Control": "public, max-age=31536000, immutable"
    },
    "/icons/*.png": {
      "Cache-Control": "public, max-age=31536000, immutable"
    }
  },
  "https_only": true,
  "error_page": "404.html"
}
