Integrate Zitadel authentication into an existing or custom TanStack Start app with @zitadel/sdk-tanstack-start. Use when the user wants login, logout, session handling, or protected routes in a TanStack Start (React) app and is wiring the SDK by hand rather than letting the CLI scaffold a fresh project — registering the request middleware in `src/start.ts`, guarding a route with a server function, or rendering the `ZitadelLogin` / `ZitadelSession` widgets.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# @zitadel/sdk-tanstack-start TanStack Start request middleware and helpers that add Zitadel (Nextgen) auth to a TanStack Start app. The middleware proxies auth traffic same-origin under `/__nextgen`, verifies the session JWT via JWKS on the server, places the result on the request context as `nextgenAuth`, and redirects unauthenticated requests on protected routes. Unlike the other meta-framework SDKs it also ships the widgets (a `/react` entry), so no other Zitadel package is needed. ## When to use The `zitadel` CLI (`zitadel setup --framework tanstack-start`) scaffolds `src/start.ts`, login/register/profile routes, and `.env.local` into a fresh or detected TanStack Start project — prefer it for greenfield work. Reach for **this skill** when you are adding auth to an **existing or custom** TanStack Start app by hand, or adjusting a scaffolded wiring. ## Install ```bash pnpm add @zitadel/sdk-tanstack-start@latest ``` Peer deps: `@tanstack/react-start >=1.168.10`, `react >=18`, `react-dom >=18`. ## Integrate **1. Request middleware.** Register it in `src/start.ts`, the file TanStack Start auto-loads, via `requestMiddleware`. Having this file turns off the automatic …

How to install
mdr add zitadel/nextgen/zitadel-sdk-tanstack-start@sha256:f6fe7475d5e3545fThe line at the top of this page pins the label git:20261021.ab19e1e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
