This module provides lightweight tooling for parsing environment variables in Deno with Zod schemas while respecting Deno's permissions tooling to make environment variable usage clear.

Permissions are requested individually for each environment variable specified in the provided schema. Permissions can be rejected without failure as long as the schema defines that variable as optional or provides a default value.

import { parseEnv } from "jsr:@keawade/zod-env";

const envSchema = z.object({
  FOO: z.string(),
  PORT: z.coerce.number().default("8080"),
  BAR: z.string().optional(),
});

const parsedEnv = parseEnv();
