| 7 | |
| 8 | `Neon.Website.TanStackStart` builds the application's client and server output, |
| 9 | then wraps the server Fetch handler for Node 24 on Neon Functions. It packages a |
| 10 | Function ZIP, not a listening Bun server, container, or S3 hosting stack. |
| 11 | |
| 12 | ## Prepare the app |
| 13 | |
| 14 | Use an existing TanStack Start app or the |
| 15 | [runnable TanStack Start example](https://github.com/alchemy-run/alchemy/tree/main/examples/neon-website-tanstack-start). |
| 16 | Configure [deployment credentials](/neon/setup), then install in the app directory: |
| 17 | |
| 18 | Install [Alchemy and its matching Effect dependencies](/getting-started) first; |
| 19 | use Node 24 for this build toolchain. |
| 20 | |
| 21 | ```sh |
| 22 | pnpm add -D @alchemy.run/frontend-frameworks @vercel/nft |
| 23 | ``` |
| 24 | |
| 25 | Keep the `tanstackStart()` and React plugins in `vite.config.*`; no deployment |
| 26 | preset is needed. Keep Vite's default `dist` output directory for this integration. |
| 27 | Application routes and the router remain normal TanStack Start code. |
| 28 | |
| 29 | ## Define the stack |
| 30 | |
| 31 | ```typescript |
| 32 | // alchemy.run.ts |
| 33 | import * as Alchemy from "alchemy"; |
| 34 | import * as Neon from "alchemy/Neon"; |
| 35 | import * as Effect from "effect/Effect"; |
| 36 | |
| 37 | export default Alchemy.Stack( |
| 38 | "NeonTanStackStart", |
| 39 | { providers: Neon.providers(), state: Alchemy.localState() }, |
| 40 | Effect.gen(function* () { |
| 41 | const site = yield* Neon.Website.TanStackStart("Web", { |
| 42 | rootDir: ".", |
| 43 | }); |
| 44 | return { url: site.url }; |
| 45 | }), |
| 46 | ); |
| 47 | ``` |
| 48 | |
| 49 | Client files are served from the artifact; unmatched requests reach the framework |
| 50 | handler for SSR and server routes. Private server-side `env` values are process |
| 51 | environment. `VITE_*` values are compiled into client code; keep privileged tokens |
| 52 | out of them and out of server-function responses. |
| 53 | |
| 54 | ## Develop and deploy |
| 55 | |
| 56 | ```sh |
| 57 | pnpm exec alchemy dev |
| 58 | pnpm exec alchemy deploy |
| 59 | pnpm exec alchemy destroy |
| 60 | ``` |
| 61 | |
| 62 | Run separately, destroying when finished. Dev uses the native Vite server and |
| 63 | HMR, returns a local URL, and creates no implicit Project or Function. Append |
| 64 | `.pipe(Alchemy.remote())` to the Website Effect to opt into live deployment during dev. |
| 65 | |
| 66 | Omitting scope creates an Ohio Project on deploy. Supply either `project` or |
| 67 | `branch` for an existing backend, and use Ohio when adding storage. Read |
| 68 | [scope and credentials](/neon/frontend/vite#scope-and-credentials) before sharing |
| 69 | backend credentials with application code. |
| 70 | |
| 71 | :::caution[Deployment limits] |
| 72 | Complete live framework acceptance remains unverified. Neon probes have served |
| 73 | old code/env despite new active deployment IDs. This integration provisions no |
| 74 | CDN or durable server cache, and registering a domain does not validate TLS. |
| 75 | See the [shared deployment limits](/neon/frontend/vite#environment-and-deployment-limits). |
