3	description: Deploy vinext to AWS with the shared Website API, native local development, and a platform-specific data cache.
4	sidebar:
5	order: 9.6
6	---
7
8	import { Code, Tabs, TabItem } from "@astrojs/starlight/components";
9
10	export const devDeps = "@alchemy.run/frontend-frameworks";
11
12	`AWS.Website.Vinext` builds with the Vinext Vite API for production and runs native
13	`vinext dev` locally. The React Server Components handler runs on a streaming Lambda Function URL.
14	S3 stores assets and CloudFront routes asset requests to S3 and other requests
15	to Lambda. This uses vinext, not OpenNext.
16
17	The Lambda target supports **App Router** applications. Use a Node deployment
18	target such as [Prisma](/prisma/frontend/vinext) or [Fly](/fly/frontend/vinext)
19	for Pages Router applications.
20
21	## Install
22
23	Keep `vinext`, `react`, `react-dom`, and `react-server-dom-webpack` in your
24	application dependencies, with `vite` and `@vitejs/plugin-rsc` for building.
25	Use vinext **1.0.0-beta.10 or newer**. Alchemy uses its standalone packaging
26	to include external runtime dependencies in the Lambda archive. Add the Alchemy integration:

29	<TabItem label="bun" icon="bun"><Code code={`bun add -d ${devDeps}`} lang="sh" /></TabItem>
30	<TabItem label="npm" icon="npm"><Code code={`npm install -D ${devDeps}`} lang="sh" /></TabItem>
31	<TabItem label="pnpm" icon="pnpm"><Code code={`pnpm add -D ${devDeps}`} lang="sh" /></TabItem>
32	<TabItem label="yarn" icon="seti:yarn"><Code code={`yarn add -D ${devDeps}`} lang="sh" /></TabItem>
33	</Tabs>
34
35	## Configure vinext
36
37	```typescript
38	// vite.config.ts
39	import { defineConfig } from "vite";
40	import vinext from "vinext";
41
42	export default defineConfig({
43	plugins: [vinext({ prerender: true })],
44	});
45	```
46
47	Alchemy injects the target-specific data-cache adapter during deployment.
48	No Alchemy plugin is required in `vite.config.ts`; deployment settings belong on
49	`Website.Vinext`. Leave Cloudflare plugins and Worker entrypoints out of this application.
50
51	## Declare the Website
52
53	```typescript
54	// alchemy.run.ts
55	import * as AWS from "alchemy/AWS";
56
57	export const Website = AWS.Website.Vinext("Website", {
58	rootDir: ".",
59	});
60	```
61
62	`rootDir`, `env`, `memo`, `assets`, `dev`, and `domain` use the same vocabulary
63	as the other Website constructors. Framework configuration stays in
64	`vite.config.ts` rather than a nested server configuration object.
65
66	## Add it to the Stack
67
68	```typescript
69	import * as Alchemy from "alchemy";
70	import * as Effect from "effect/Effect";
71
72	export default Alchemy.Stack(
73	"MyVinextSite",
74	{ providers: AWS.providers(), state: Alchemy.localState() },
75	Effect.gen(function* () {
76	const site = yield* Website;
77	return { url: site.url };
78	}),
79	);
80	```
81
82	Keep the local state available for subsequent deploys and teardown.
83
84	## Add environment variables
85
86	```typescript
87	export const Website = AWS.Website.Vinext("Website", {
88	env: { GREETING: "Hello from vinext on AWS!" },
89	});
90	```
91
92	`env` is available during build, development, and production. Server code reads
93	`process.env`; public framework variables may be compiled into browser assets.
94	Keep secrets out of public keys and wrap credentials in `Redacted`.
95
96	## Read the runtime environment
97
98	```typescript
99	// app/api/hello/route.ts
100	export function GET(request: Request) {
101	const name = new URL(request.url).searchParams.get("name") ?? "world";
102	return Response.json({ name, greeting: process.env.GREETING ?? "hello" });
103	}
104	```
105
106	Request-dependent route handlers read the production environment. A prerendered
107	page reflects its build-time inputs instead.
108
109	## Configure the data cache
110
111	The Website provisions an S3 bucket for ISR and `"use cache"`, sets
112	`CACHE_BUCKET_NAME`, and grants the Lambda access. The build selects the S3
113	adapter. Local development uses memory and creates no bucket.
114
115	## Local development
116
117	```sh
118	bun alchemy dev
119	```
120
121	The Website runs `vinext dev` with native HMR and creates no cloud resources.
122	Other resources declared in the Stack retain their own provider behavior.
123	Apply `.pipe(Alchemy.remote())` to the Website for a live deployment during dev.
124
125	## Custom domains
126
127	```typescript
128	const site = yield* AWS.Website.Vinext("Web", {
129	domain: "app.example.com",
130	});
131	```
132
133	See [Website domains](/aws/frontend/websites) for platform-specific DNS and
134	certificate configuration.
