But how I'm supposed to access them from a static web page(I don't want to access them in development/local, I eman production once it is deployed), will the env variable be accessible? In a worker the context comes from the event onRequest but how from a worker page?

So I have a react static page, built with vite(rollup), I need to create a functions folder and listen to fetch events like this:

export default {
  async fetch(request, env) {
    const url = new URL(request.url);

    if (url.pathname.startsWith('/api/')) {
      const apiRequest = new Request(
        `https://your-worker-url.com${url.pathname}`,
        request
      );
      return env.MY_WORKER_SERVICE.fetch(apiRequest);
    }

    return env.ASSETS.fetch(request);
  },
};

});

export default {
  async fetch(request, env) {
    const url = new URL(request.url);

    if (url.pathname.startsWith('/api/')) {
      const apiRequest = new Request(
        `https://your-worker-url.com${url.pathname}`,
        request
      );
      return env.MY_WORKER_SERVICE.fetch(apiRequest);
    }

    return env.ASSETS.fetch(request);
  },
};

});

export default {
  async fetch(request, env) {
    const url = new URL(request.url);

    if (url.pathname.startsWith('/api/')) {
      const apiRequest = new Request(
        `https://your-worker-url.com${url.pathname}`,
        request
      );
      return env.MY_WORKER_SERVICE.fetch(apiRequest);
    }

    return env.ASSETS.fetch(request);
  },
};

});

export default {
  async fetch(request, env) {
    const url = new URL(request.url);

    if (url.pathname.startsWith('/api/')) {
      const apiRequest = new Request(
        `https://your-worker-url.com${url.pathname}`,
        request
      );
      return env.MY_WORKER_SERVICE.fetch(apiRequest);
    }

    return env.ASSETS.fetch(request);
  },
};

});

In this example, MY_WORKER_SERVICE is the name I gave to the service binding in the Cloudflare Pages dashboard.
using the SERVICE and in the static code just request to localhost/api.....?

You probably want this instead:

// functions/api/[[route]].ts
export const onRequest: PagesFunction = ({ request }) => {
  const url = new URL(request.url);
  url.host = "your-worker-url.com";
  return fetch(url.toString(), request);
};

// functions/api/[[route]].ts
export const onRequest: PagesFunction = ({ request }) => {
  const url = new URL(request.url);
  url.host = "your-worker-url.com";
  return fetch(url.toString(), request);
};

// functions/api/[[route]].ts
export const onRequest: PagesFunction = ({ request }) => {
  const url = new URL(request.url);
  url.host = "your-worker-url.com";
  return fetch(url.toString(), request);
};

Just went and checked... was about to say that problem remained when using a sub-directory when I fumbled switching apps and landed in my browser and saw the correct content... it appears that the issue (whether content is at root or in a subdirectory) is that it takes time for wrangler to get itself into a position where it can respond (on my machine that seems to often take 11 or 12ish seconds). At that point, I get the following in the console (which seems to be the same time when the browser returns content):

wth is 'Advanced mode'? Lol

Edit: Found the docs for it.

In advanced mode, your Function will assume full control of all incoming HTTP requests to your domain. Your Function is required to make or forward requests to your project’s static assets. Failure to do so will result in broken or unwanted behavior. Your Function must be written in Module syntax.

Well, there goes my curiosity out the window :wave_animated:

Meanwhile... I'm not sure how I can write the

_routes.json

_routes.json

_routes.json to exclude all paths except the ones I define explicitly (such as

/api/*

/api/*

/api/*

/api/*).
Seems like the file is meant to work the other way around... since excludes takes precendence over includes... so I can't do

{
    "version": 1,
    "include": ["/api/*"],
    "exclude": ["/*"]
}

{
    "version": 1,
    "include": ["/api/*"],
    "exclude": ["/*"]
}

{
    "version": 1,
    "include": ["/api/*"],
    "exclude": ["/*"]
}

{
    "version": 1,
    "include": ["/api/*"],

Right?
