Basic Implementation

1. Env Configuration

export const envSchema = z.object({
  NODE_ENV: z
    .enum(["development", "test", "production"])
    .default("development")
 
  DATABASE_URL: z.url(),
});
 
export type Env = z.infer<typeof envSchema>;
 
const result = envSchema.safeParse(process.env);
 
if (!result.success) {
  console.error("❌ Invalid environment configuration");
  console.error(z.prettifyError(result.error));
  process.exit(1);
}
 
export const env: Readonly<Env> = Object.freeze(result.data);
 
export default env;

2. Database Client

src/configs/db.ts
import { drizzle } from "drizzle-orm/mysql2";
import env from "./env";
 
const db = drizzle(env.DATABASE_URL!, {
  logger: env.NODE_ENV === "development"
});
 
export default db;
