cli not generating migration files due to cf bindings usage

im trying to set up better auth on cf workers (currently with hono, but would switch once this i would find a fix for this). i have the following betterauth config:

// auth.ts
import { betterAuth } from "better-auth";
import { z } from "zod";

export const createAuth = (env: Env) =>
  betterAuth({
    basePath: "/api/auth",
    database: env.AUTH_DB,
    socialProviders: {
      google: {
        clientId: env.GOOGLE_CLIENT_ID,
        clientSecret: env.GOOGLE_CLIENT_SECRET,
      },
    },
    user: {
      additionalFields: {
        role: {
          type: "string",
          validator: {
            input: z.enum(["guest", "user", "admin"]).default("guest"),
          },
        },
        active: {
          type: "boolean",
          validator: {
            input: z.boolean(),
          },
          defaultValue: false,
        },
      },
    },
  });

// auth.ts
import { betterAuth } from "better-auth";
import { z } from "zod";

export const createAuth = (env: Env) =>
  betterAuth({
    basePath: "/api/auth",
    database: env.AUTH_DB,
    socialProviders: {
      google: {
        clientId: env.GOOGLE_CLIENT_ID,
        clientSecret: env.GOOGLE_CLIENT_SECRET,
      },
    },
    user: {
      additionalFields: {
        role: {
          type: "string",
          validator: {
            input: z.enum(["guest", "user", "admin"]).default("guest"),
          },
        },
        active: {
          type: "boolean",
          validator: {
            input: z.boolean(),
          },
          defaultValue: false,
        },
      },
    },
  });

it has to be a function as i need to pass the cf env in somehow. this is where the client is created:

// index.ts
import { Hono } from "hono";
import { cors } from "hono/cors";
import { createAuth } from "./auth";

const app = new Hono<{ Bindings: Env }>();

app.use("/api/auth/*", async (c, next) => {
  const corsMiddlewareHandler = cors({
    origin: c.env.ALLOWED_ORIGIN,
    allowHeaders: ["Content-Type", "Authorization"],
    allowMethods: ["POST", "GET", "OPTIONS"],
    exposeHeaders: ["Content-Length"],
    maxAge: 600,
    credentials: true,
  });
  return corsMiddlewareHandler(c, next);
});

app.on(["POST", "GET"], "/api/auth/*", (c) => {
  return createAuth(c.env).handler(c.req.raw);
});

export default app satisfies ExportedHandler<Env>;

// index.ts
import { Hono } from "hono";
import { cors } from "hono/cors";
import { createAuth } from "./auth";

const app = new Hono<{ Bindings: Env }>();

app.use("/api/auth/*", async (c, next) => {
  const corsMiddlewareHandler = cors({
    origin: c.env.ALLOWED_ORIGIN,
    allowHeaders: ["Content-Type", "Authorization"],
    allowMethods: ["POST", "GET", "OPTIONS"],
    exposeHeaders: ["Content-Length"],
    maxAge: 600,
    credentials: true,
  });
  return corsMiddlewareHandler(c, next);
});

app.on(["POST", "GET"], "/api/auth/*", (c) => {
  return createAuth(c.env).handler(c.req.raw);
});

export default app satisfies ExportedHandler<Env>;

has anyone experienced this aswell before? im aware that the cli is trying to look for a config exported under the name auth, but under my circumstances it's simply just not possible

nextjs / trpc as backend vs dedicated backend

maybe a bit better to ask here hehe: i had been wondering about this for a while, but when do you guys usually decide that trpc / server actions / nextjs api routes are just not enough and move off to a separate backend?
