Environment Variables

The project uses Zod  for type-safe environment variable validation at startup.

Application Environment Variables

Environment variables are validated against the envSchema defined in app/lib/env.ts.

NODE_ENV

• Type: 'development' | 'production' | 'test'
• Default: 'development'
• Description: Standard environment mode indicator.

BLOB_READ_WRITE_TOKEN

• Type: string (Optional)
• Format: Must begin with vercel_blob_rw_
• Description: Read/write token for Vercel Blob object storage.

Deployment Tokens (CI / Local Deployments)

These tokens are used by deployment workflows in .github/workflows/deploy.yml and local deployment tasks defined in .mise.toml:

• VERCEL_TOKEN: Authentication token for automated deployments using Vercel CLI.
• RENDER_DEPLOY_HOOK: Webhook URL for triggering automated deployments to Render.
• FIREBASE_TOKEN: Authentication token for deploying to Firebase Hosting via Firebase CLI.

Schema Definition

import { z } from "zod";
 
const envSchema = z.object({
  NODE_ENV: z.enum(["development", "production", "test"]).default("development"),
  BLOB_READ_WRITE_TOKEN: z
    .string()
    .min(1)
    .startsWith("vercel_blob_rw_", "Token must start with 'vercel_blob_rw_'")
    .optional(),
});
 
export const env = envSchema.parse({
  NODE_ENV: process.env.NODE_ENV,
  BLOB_READ_WRITE_TOKEN: process.env.BLOB_READ_WRITE_TOKEN,
});
 
export type Env = z.infer<typeof envSchema>;
