This entrypoint exposes the root package's client-safe configuration, platform, routing, data, and security helpers without server bootstrap functions. Most app code can import these helpers from `veryfront`; use this explicit entrypoint when a browser or SSR module needs to declare that boundary directly. ## Import ```ts theme={null} import { apiNotFound, apiRedirect, badRequest, createValidatedHandler, createValidationError, defineConfig, } from "veryfront/index.client"; ``` ## Examples ```ts theme={null} import { getEnv, json } from "veryfront/index.client"; export function GET() { return json({ mode: getEnv("MODE") ?? "development" }); } ``` ## Exports ### Components | Name | Description | Source | | ------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | -------------------------------------------------------------------------------------------------------- | | `CommonSchemas` | Lazy-getter object that preserves the `CommonSchemas.email` call shape.
