Guides | ArkEnv

Assistants, NestJS, Nub, Docker, and migrations sit in this section. ArkEnv's guides cover those paths, from T3 Env and a getEnv helper through v0.

Framework and validator setups live in their own sections. Start here when the question is a migration or a host recipe.

Validate environment variables in NestJS with a fail-fast env module.

Load .env with Nub and validate earlier with preload, arkenv check, or script gates.

Bake-time NEXT_PUBLIC_* values, runtime secrets, and ecosystem options for no-rebuild public env.

Install the plugin. Skill only if the host cannot load plugins.

Swap v0 packages and move Vite or Bun onto import { env } from ./env.

Move createEnv and runtimeEnv setups to ArkEnv.

Graduate from a 12-line presence check helper to typed coercion and boundary enforcement.
