Access D1 database outside a request

You can create a middleware that you set a d1 clousure instance and use it without passing context.d1 to your functions that need dababase: ex:

class D1 {
  private _db: D1Database | undefined;

  get db() {
    return this._db as D1Database;
  }

  setDb(db: D1Database) {
    this._db = db;
  }
}

export default new D1();

class D1 {
  private _db: D1Database | undefined;

  get db() {
    return this._db as D1Database;
  }

  setDb(db: D1Database) {
    this._db = db;
  }
}

export default new D1();

the middleware before all req could be like that:

import D1 from ''

return async function PrepareDBMiddleware(c: Context, next: () => any) {
    D1.setDb(c.D1);
    await next();
}

import D1 from ''

return async function PrepareDBMiddleware(c: Context, next: () => any) {
    D1.setDb(c.D1);
    await next();
}

to use

import D1 from ''

const clients = await D1.db.prepare('').........

import D1 from ''

const clients = await D1.db.prepare('').........

Cors blocking using Hono.js and workers

app.use("*", async (c, next) => {
  const corsMiddleware = cors({
    origin: ["*"],
    allowMethods: ["GET", "OPTIONS", "POST", "PUT", "DELETE"],
    credentials: true,
  });
  return corsMiddleware(c, next);
});

app.use("*", async (c, next) => {
  const corsMiddleware = cors({
    origin: ["*"],
    allowMethods: ["GET", "OPTIONS", "POST", "PUT", "DELETE"],
    credentials: true,
  });
  return corsMiddleware(c, next);
});

This way it works when calling from localhost:3000, but not from cloudflare pages (https://develop.scheduling-next-front-end.pages.dev)

Cors blocking using Hono.js and workers

I think that the blocking is happening before it reaches my application. Because when I remove the origin from http://localhost:3000 and try to access from localhost:3000 I have see the OPTIONS logs in the WORKER panel, but when I try to access from "https://develop.scheduling-next-front-end.pages.dev" I havent see the OPTIONS logs in the worker panel. Is there any CORS blocking in Cloud Flare before it reaches my application?
