TanStack Start is an open-source, fully type-safe web framework for building feature rich React and Solid based applications using the TanStack ecosystem.
To create a Neon project and access it from a Start application:
## Create a Neon project
If you do not have one already, create a Neon project. Save your connection details including your password. They are required when defining connection settings.
1. Navigate to the [Projects](https://console.neon.tech/app/projects) page in the Neon Console.
2. Click **New Project**.
3. Specify your project settings and click **Create Project**.
## Create a Start project and add dependencies
1. Create a Start project if you do not have one. For instructions see the [quick start guides](https://tanstack.com/start/latest), in the [TanStack](https://tanstack.com/) documentation.
2. Add project dependencies using one of the following commands:
```shell
npm install pg
```
```shell
npm install postgres
```
```shell
npm install @neondatabase/serverless
```
## Store your Neon credentials
Add a `.env` file to your project directory and add your Neon connection string to it. You can find your Neon database connection string by clicking the **Connect** button on your **Project Dashboard** to open the **Connect to your database** modal. For more information, see [Connect from any application](/docs/connect/connect-from-any-app).
```shell shouldWrap
DATABASE_URL="postgresql://:@.neon.tech:/?sslmode=require&channel_binding=require"
```
If you haven't created a database yet, run the following command to generate a [Neon Instagres DB](https://neon.new/). It will spin up a database instance that you can use for 72 hours, or claim to keep forever.
```bash
npm get-db
```
```bash
yarn dlx get-db
```
```bash
pnpm get-db
```
```bash
bunx get-db
```
```bash
deno run -A get-db
```
## Configure the Postgres client
There are multiple ways to make server side requests with TanStack Start. See below for the different implementations.
### Server Functions
In your server functions, add the following code snippet to connect to your Neon database:
```typescript filename="src/data/get-neon-data.ts"
import { Pool } from 'pg';
import { createServerFn } from "@tanstack/react-start";
const pool = new Pool({
connectionString: process.env.DATABASE_URL,
ssl: true,
});
export const getData = createServerFn({ method: "GET" }).handler(async () => {
const client = await pool.connect();
try {
const { rows } = await client.query('SELECT version()');
return rows[0].version;
} finally {
client.release();
}
});
```
```typescript filename="src/data/get-neon-data.ts"
import postgres from 'postgres';
import { createServerFn } from "@tanstack/react-start";
export const getData = createServerFn({ method: "GET" }).handler(async () => {
const sql = postgres(process.env.DATABASE_URL, { ssl: 'require' });
const response = await sql`SELECT version()`;
return response[0].version;
});
```
```typescript filename="src/data/get-neon-data.ts"
import { neon } from "@neondatabase/serverless";
import { createServerFn } from "@tanstack/react-start";
export const getData = createServerFn({ method: "GET" }).handler(async () => {
const sql = neon(process.env.DATABASE_URL);
const response = await sql`SELECT version()`;
return response[0].version;
});
```
Then consume the data in your start application, like you would normally, with any other data fetching operation.
```typescript filename="src/routes/index.tsx"
import { createFileRoute } from "@tanstack/react-router";
import { getData } from "../data/get-neon-data.ts";
export const Route = createFileRoute("/")({
loader: async () => {
return getData();
},
component: RouteComponent,
});
export default function RouteComponent() {
const data = Route.useLoaderData();
return <>{data}>;
}
```
### Static Server Functions
In your static server functions, add the following code snippet to connect to your Neon database:
```typescript filename="src/data/get-neon-data.ts"
import { Pool } from 'pg';
import { createServerFn } from "@tanstack/react-start";
import { staticFunctionMiddleware } from "@tanstack/start-static-server-functions";
const pool = new Pool({
connectionString: process.env.DATABASE_URL,
ssl: true,
});
export const getData = createServerFn({ method: "GET" })
.middleware([staticFunctionMiddleware])
.handler(async () => {
const client = await pool.connect();
try {
const { rows } = await client.query('SELECT version()');
return rows[0].version;
} finally {
client.release();
}
});
```
```typescript filename="src/data/get-neon-data.ts"
import postgres from 'postgres';
import { createServerFn } from "@tanstack/react-start";
import { staticFunctionMiddleware } from "@tanstack/start-static-server-functions";
export const getData = createServerFn({ method: "GET" })
.middleware([staticFunctionMiddleware])
.handler(async () => {
const sql = postgres(process.env.DATABASE_URL, { ssl: 'require' });
const response = await sql`SELECT version()`;
return response[0].version;
});
```
```typescript filename="src/data/get-neon-data.ts"
import { neon } from "@neondatabase/serverless";
import { createServerFn } from "@tanstack/react-start";
import { staticFunctionMiddleware } from "@tanstack/start-static-server-functions";
export const getData = createServerFn({ method: "GET" })
.middleware([staticFunctionMiddleware])
.handler(async () => {
const sql = neon(process.env.DATABASE_URL);
const response = await sql`SELECT version()`;
return response[0].version;
});
```
Then like before you can consume the data in your components.
_Be aware Static Server Functions are executed at build time, and cached as a static asset for pre-rendering or static generation_.
```typescript filename="src/routes/index.tsx"
import { createFileRoute } from "@tanstack/react-router";
import { getData } from "../data/get-neon-data.ts";
export const Route = createFileRoute("/")({
loader: async () => {
return getData();
},
component: RouteComponent,
});
export default function RouteComponent() {
const data = Route.useLoaderData();
return <>{data}>;
}
```
## Run the app
When you run `npm run dev` you can expect to see the following on [localhost:3000](http://localhost:3000/):
```shell shouldWrap
PostgreSQL 16.0 on x86_64-pc-linux-gnu, compiled by gcc (Debian 10.2.1-6) 10.2.1 20210110, 64-bit
```
### Where to upload and serve files?
Neon does not provide a built-in file storage service. For managing binary file data (blobs), we recommend a pattern that leverages dedicated, specialized storage services. Follow our guide on [File Storage](/docs/guides/file-storage) to learn more about how to store files in external object storage and file management services and track metadata in Neon.

You can find the source code for the applications described in this guide on GitHub.
