// src/app/blitz-server.ts
import type { BlitzCliConfig } from "blitz";
import {setupBlitzServer} from "@blitzjs/next"
import {AuthServerPlugin, PrismaStorage, simpleRolesIsAuthorized} from "@blitzjs/auth"
import db from "db"
import {BlitzLogger} from "blitz"
import {RpcServerPlugin} from "@blitzjs/rpc"
import {authConfig} from "./blitz-auth-config"

const {api, getBlitzContext, useAuthenticatedBlitzContext, invoke,withBlitzAuth} = setupBlitzServer({
plugins: [
AuthServerPlugin({
...authConfig,
storage: PrismaStorage(db),
isAuthorized: simpleRolesIsAuthorized,
}),
RpcServerPlugin({}),
],
logger: BlitzLogger({}),
})

export {api, getBlitzContext, useAuthenticatedBlitzContext, invoke,withBlitzAuth}

export const cliConfig: BlitzCliConfig = {
customTemplates: "src/templates"
};
```

##### generated file

```tsx
// src/app/notes/new/page.tsx
import { Metadata } from "next";
import { Suspense } from "react";
import { New__ModelName } from "../components/NewNote";

export const metadata: Metadata = {
title: "New Project",
description: "Create a new project",
};

export default function Page() {
return (

}>



);
}
```

##### expected use template, but [blitz/packages/generator/templates/route/new/page.tsx at main · blitz-js/blitz · GitHub](https://github.com/blitz-js/blitz/blob/main/packages/generator/templates/route/new/page.tsx)
```tsx

import { useRouter } from "next/router"
import {useMutation} from '@blitzjs/rpc'
} else {
import Link from 'next/link'

}
import Layout from "src/core/layouts/Layout"

const router = useRouter()
if (process.env.parentModel) {
const __parentModelId__ = useParam("__parentModelId__", "number")

const [create__ModelName__Mutation] = useMutation(create__ModelName__)

return (

onSubmit={async (values) => {
try {
const __modelName__ = await create__ModelName__Mutation(
process.env.parentModel
? {...values, __parentModelId__: __parentModelId__!}
: values,
)
await router.push(
process.env.parentModel
? Routes.Show__ModelName__Page({ __parentModelId__: __parentModelId__!, __modelId__: __modelName__.id })
: Routes.Show__ModelName__Page({ __modelId__: __modelName__.id }),

} catch (error: any) {
console.error(error)
return {

}
}}

New__ModelName__Page.authenticate = true

export default New__ModelName__Page

```
