Type-Safe Environment Variables Validation

Environmental configurations play a vital role in application deployment. If variables are missing or misconfigured, applications may fail at runtime, causing production downtime.

Validate Config on Boot

Instead of checking process.env properties throughout your codebase, define a schema validation block at application startup. ForgeKit’s upcoming @doyzfin/config implements Zod assertions schema triggers on startup:

import { z } from '@doyzfin/config';

const envSchema = z.object({
	DATABASE_URL: z.string().url(),
	PORT: z.number().default(3000)
});

Benefits of Startup Assertions

• Fail Fast: Catch configuration typos during initial server booting rather than during a transaction call.
• Static Autocomplete: TypeScript knows that DATABASE_URL is a valid URL string, preventing type assertions.
• Default Variables: Bind fallback values locally when working in development setups.
