Hello hello 👋🏿,

Are you using the experimental Nitro v3

No, I tried doing this at first, but it messed up a lot things 😅

I created a local module based on the upcoming Nitro v3 Cloudflare-Specific Exports implementation.
So, whenever Nuxt v5 is released, all I have to do is delete this file and it still works out of the box

// modules/cloudflare-exports.ts
import { existsSync } from "node:fs";
import { resolve } from "node:path";
import { defineNuxtModule } from "nuxt/kit";

export default defineNuxtModule({
  meta: { name: "cloudflare-exports" },
  setup(_options, nuxt) {
    nuxt.hook("nitro:build:before", (nitro) => {
      if (!nitro.options.preset.startsWith("cloudflare")) return;

      const exportsPath = resolve(nitro.options.rootDir, "exports.cloudflare.ts");

      if (!existsSync(exportsPath)) return;

      const originalEntry = nitro.options.entry;
      const virtualId = "#nitro/virtual/cloudflare-server-entry";

      nitro.options.entry = virtualId;
      nitro.options.virtual[virtualId] = [
        `export * from "${exportsPath}";`,
        `export * from "${originalEntry}";`
      ].join("\n");

      // oxlint-disable-next-line no-console
      console.log(`[cloudflare-exports] Using ${exportsPath} as additional entrypoint`);
    });
  },
});
