…les in React Start apps - Added a new add-on, ArkEnv, which provides typesafe environment variable validation with build-time validation and runtime leak protection. - Includes a demo route to showcase server-only keys and their protection. - Supports multiple validator options: ArkType, Zod, and Valibot. - Updated documentation and example files for usage guidance. This enhances the tooling available for managing environment variables in TanStack Start applications.
- Updated the exclusive add-ons array in the AddOnBaseSchema to include 'env', allowing for better management of environment-related add-ons.

The add-on generates validator-specific environment schemas and dependencies, supports an optional demo route, and is marked exclusive with T3Env. It also updates how template integration imports are rendered. ChangesArkEnv add-on

Security Architecture ReviewSecurity architecture risk: 🟡 Moderate · up to The optional demo returns fixed example values rather than the database URL. However, it also deliberately reads the server-only variable in browser code, relying on protection that has not been verified here. The generated configuration supplies a predictable database-URL fallback. Retained concerns

…apps - Updated the description to clarify that the add-on provides environment variable validation. - Added functionality for `tanstack add arkenv` to write `src/env.ts`, register `@arkenv/vite-plugin`, and create a `/demo/arkenv` route. - Included selectable validators: ArkType, Zod, and Valibot, with mutual exclusivity between ArkEnv and T3Env due to both writing `src/env.ts`.
- Improved formatting of the description for better readability. - Clarified the functionality of `tanstack add arkenv`, including its effects on `src/env.ts`, registration of `@arkenv/vite-plugin`, and the addition of a `/demo/arkenv` route. - Maintained details on selectable validators and mutual exclusivity between ArkEnv and T3Env.
- Streamlined the structure by removing unnecessary fields while retaining essential information. - Updated and to simplify validator option handling. - Enhanced the demo route in for better readability and maintainability, ensuring proper handling of server-only variables and client access attempts. - Improved overall code formatting for consistency and clarity.

minimum 1 and maximum 65535 checks after v.integer(), rejecting out-of-range
values and empty values converted to 0.

`@packages/create/src/frameworks/react/add-ons/arkenv/assets/src/routes/demo/arkenv.tsx.ejs`:
- Line 11: Update the demo server function that returns `{ host, protocol }` so
it returns illustrative values instead of parsing or exposing the deployed
`DATABASE_URL`; ensure its result cannot reveal the database endpoint.
In `@packages/create/src/frameworks/react/add-ons/arkenv/info.json`:
- Line 45: Update the ArkEnv import in the integration’s info.json to use the
standard Vite plugin entrypoint for both Zod and Valibot selections, matching
the `@arkenv/standard` import generated in `env.ts`.

Zod and Valibot need the standard Vite plugin, the Valibot port schema should reject values outside 1-65535, and the demo route should not send the deployed database host to the browser.

The ArkEnv Vite import is EJS inside info.json. Edge and worker generation only render templates registered in the manifest, so that import has to be compiled while the manifest is built.
