Install:
pnpm add nviron
npm install nviron
yarn add nviron
Define and validate your environment:
import { defineEnv, z } from "nviron"; const env = defineEnv({ PORT: z.coerce.number(), DATABASE_URL: z.string().url(), }); console.log(env.PORT);
Use custom source and prefix (for example Vite):
import { defineEnv, z } from "nviron"; const env = defineEnv( { PORT: z.coerce.number(), DATABASE_URL: z.string().url(), }, { source: import.meta.env, prefix: "VITE_", }, );
