## Usage Examples
352

353
### Using Vercel Preset
354

355
```typescript
356
import { createEnv } from "@t3-oss/env-nextjs";
357
import { vercel } from "@t3-oss/env-nextjs/presets-zod";
358
import { z } from "zod";
359

360
const vercelEnv = vercel();
361

362
const env = createEnv({
363
  server: {
364
    DATABASE_URL: z.string().url(),
365
  },
366
  client: {
367
    NEXT_PUBLIC_APP_URL: z.string().url(),
368
  },
369
  extends: [vercelEnv],
370
  runtimeEnv: {
371
    DATABASE_URL: process.env.DATABASE_URL,
372
    NEXT_PUBLIC_APP_URL: process.env.NEXT_PUBLIC_APP_URL,
373
    // Vercel variables are automatically available
374
  },
375
});
376

377
// Access Vercel-specific variables
378
console.log(env.VERCEL_ENV); // "development" | "preview" | "production" | undefined
379
console.log(env.VERCEL_URL); // string | undefined
380
```
381

382
### Combining Multiple Presets
383

384
```typescript
385
import { createEnv } from "@t3-oss/env-nextjs";
386
import { vercel, neonVercel } from "@t3-oss/env-nextjs/presets-zod";
387
import { z } from "zod";
388

389
const vercelEnv = vercel();
390
const neonEnv = neonVercel();
391

392
const env = createEnv({
393
  server: {
394
    JWT_SECRET: z.string().min(32),
395
  },
396
  client: {
397
    NEXT_PUBLIC_APP_URL: z.string().url(),
398
  },
399
  extends: [vercelEnv, neonEnv],
400
  runtimeEnv: {
401
    JWT_SECRET: process.env.JWT_SECRET,
402
    NEXT_PUBLIC_APP_URL: process.env.NEXT_PUBLIC_APP_URL,
403
    // Both Vercel and Neon variables are available
404
  },
405
});
406

407
// Access variables from both presets
408
console.log(env.VERCEL_ENV); // From Vercel preset
409
console.log(env.DATABASE_URL); // From Neon preset
410
```
