Im planning to deploy my application on vercel, and I'm not tech savy on edge and stuff so I wonder is this the correct way to connect to db and handle some data?
My db.ts file:

import { drizzle } from "drizzle-orm/postgres-js";
import postgres from "postgres";

import * as schema from "./schema";

import "dotenv/config";

const getEnvVariable = (name: string) => {
  const value = process.env[name];
  if (value == null) throw new Error(`Environment variable ${name} not found`);
  return value;
};

export const client = postgres(getEnvVariable("DATABASE_URL"));

export const db = drizzle(client, { schema });

This is how I use db:

import { db } from "@/lib/db";
import { usersTable } from "@/lib/schema";

export const dynamic = "force-dynamic"; // defaults to auto
export async function GET() {
  const users = await db.select().from(usersTable);

  return Response.json(users);
}

So is this fine for the cold start and all those serverless edge jazz?
