All routes are missing after `deno compile`

[hronro]

Steps to reproduce:

deno compile -A --include static/ --include _fresh --output fresh_server main.ts
mv ./fresh_server /tmp/
cd /tmp/
./fresh_server

When you open the page in the browser, all routes will return a 404 error.

Please note you have to move the executable to somewhere else other than the project directory. If the executable still stays in the project directory, the routes won't be missed. Seems like the executable is still linking some JS/TS files outside the executable.

I used deno run -Ar jsr:@fresh/init@2.0.0-alpha.46 to create a new project, then added a simple about.tsx file in the routes folder.

./routes/about.tsx

import { define } from "../utils.ts";

export default define.page(function About() {
  return <h1>About</h1>;
});

After running deno task build, I modified the _fresh/server.js file by commenting out export default { fetch: app.handler() } and adding Deno.serve(app.handler()).

./_fresh/server.js

// WARNING: DO NOT EDIT THIS FILE. It is autogenerated by Fresh.
import { setBuildCache, ProdBuildCache, path } from "fresh/do-not-use";
import * as snapshot from "./snapshot.js";
import { app } from "../main.ts";

const root = path.join(import.meta.dirname, "..");
setBuildCache(app, new ProdBuildCache(root, snapshot));

// export default {
//   fetch: app.handler()
// }


Deno.serve(app.handler());

Then I ran deno compile --allow-all --include _fresh --include static _fresh/server.js to package it as an executable file.

After copying the packaged file to another path and running it, the following routes are all accessible:

• http://localhost:8000
• http://localhost:8000/about
• http;//localhost:8000/api/hi

@hronro Which Fresh version did you use? #3122 changed the entrypoint to be _fresh/server.js instead of main.ts, so Alpha 44 (released the same day as this issue) and later should use the deno compile script mentioned above by @andy259.

[hronro]

Cool, I believe the version I used when I posted this issue is Alpha 40.

It would be great if Deno could compile the deno serve command into a single executable, allowing me to enjoy both a standalone executable and automatic parallel workers simultaneously. (which I already made a feature request in the main Deno repo last year: denoland/deno#27210)

[hronro]

I'll keep this issue open for now, as it currently requires me to manually edit the _fresh/server.js file, which begins with the warning: // WARNING: DO NOT EDIT THIS FILE. Let's wait for a more elegant solution.

A more elegant fix is to probably write a custom file like:

// _fresh/compile-entry.ts
import fetcher from "./server.js";

Deno.serve(fetcher.fetch)

We should do that in Fresh directly and add docs for deno compile to use that entry instead of _fresh/server.js
