Connect a SolidStart application to Neon

Summary: SolidStart integration with Neon walks through creating a Neon project and querying a serverless Postgres database from a SolidJS meta-framework app. Covers server-side data loading and API routes using node-postgres, postgres.js, or the Neon serverless driver.

Connect a SolidStart application to Neon

Section titled “Connect a SolidStart application to Neon”

SolidStart is an open-source meta-framework designed to integrate the components that make up a web application.1. This guide explains how to connect SolidStart with Neon using a secure server-side request.

To create a Neon project and access it from a SolidStart application:

Create a Neon project

Section titled “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 page in the Neon Console.
  2. Click New Project.
  3. Specify your project settings and click Create Project.

Create a SolidStart project and add dependencies

Section titled “Create a SolidStart project and add dependencies”

  1. Create a SolidStart project if you do not have one. For instructions, see Quick Start, in the SolidStart documentation.

  2. Add project dependencies using one of the following commands:

    node-postgres

    Shell
    npm install pg

    postgres.js

    Shell
    npm install postgres

    Neon serverless driver

    Shell
    npm install @neondatabase/serverless

Store your Neon credentials

Section titled “Store your Neon credentials”

Add a .env file to your project directory and add your Neon connection string to it. You can find the connection string for your database by clicking the Connect button in the Console nav. For more information, see Connect from any application.

Shell
DATABASE_URL="postgresql://<user>:<password>@<endpoint_hostname>.neon.tech:<port>/<dbname>?sslmode=require&channel_binding=require"

Configure the Postgres client

Section titled “Configure the Postgres client”

There a multiple ways to make server-side requests with SolidStart. See below for the different implementations.

Server-Side Data Loading

Section titled “Server-Side Data Loading”

To load data on the server in SolidStart, add the following code snippet to connect to your Neon database:

node-postgres

TypeScript
import pg from 'pg';
import { createAsync, query } from "@solidjs/router";

const getVersion = query(async () => {
    "use server";
    const pool = new pg.Pool({
        connectionString: process.env.DATABASE_URL,
    });
    const client = await pool.connect();
    const response = await client.query('SELECT version()');
    return response.rows[0].version;
}, 'version')

export const route = {
  preload: () => getVersion(),
};

export default function Page() {
  const version = createAsync(() => getVersion());
  return <>{version()}</>;
}

postgres.js

TypeScript
import postgres from 'postgres';
import { createAsync, query } from "@solidjs/router";

const getVersion = query(async () => {
    "use server";
    const sql = postgres(process.env.DATABASE_URL, { ssl: 'require' });
    const response = await sql`SELECT version()`;
    return response[0].version;
}, 'version')

export const route = {
  preload: () => getVersion(),
};

export default function Page() {
  const version = createAsync(() => getVersion());
  return <>{version()}</>;
}

Neon serverless driver

TypeScript
import { neon } from "@neondatabase/serverless";
import { createAsync, query } from "@solidjs/router";

const getVersion = query(async () => {
    "use server";
    const sql = neon(process.env.DATABASE_URL);
    const response = await sql`SELECT version()`;
    const { version } = response[0];

    return version;
}, 'version')

export const route = {
  preload: () => getVersion(),
};

export default function Page() {
  const version = createAsync(() => getVersion());
  return <>{version()}</>;
}

Server Endpoints (API Routes)

Section titled “Server Endpoints (API Routes)”

In your server endpoints (API Routes) in your SolidStart application, use the following code snippet to connect to your Neon database:

node-postgres

JavaScript
// File: routes/api/test.ts

import { Pool } from 'pg';
import { json } from '@solidjs/router';

const pool = new Pool({
  connectionString: process.env.DATABASE_URL,
  ssl: true,
});

export async function GET() {
  const client = await pool.connect();
  let data = {};
  try {
    const { rows } = await client.query('SELECT version()');
    data = rows[0];
  } finally {
    client.release();
  }
  return json(data);
}

postgres.js

JavaScript
// File: routes/api/test.ts

import postgres from 'postgres';
import { json } from '@solidjs/router';

export async function GET() {
  const sql = postgres(process.env.DATABASE_URL, { ssl: 'require' });
  const response = await sql`SELECT version()`;

  return json(response[0]);
}

Neon serverless driver

JavaScript
// File: routes/api/test.ts

import { neon } from '@neondatabase/serverless';
import { json } from '@solidjs/router'

export async function GET() {
  const sql = neon(process.env.DATABASE_URL!);
  const response = await sql`SELECT version()`;

  return json(response[0]);
}

Run the app

Section titled “Run the app”

When you run npm run dev you can expect to see the following on localhost:3000:

Shell
PostgreSQL 16.0 on x86_64-pc-linux-gnu, compiled by gcc (Debian 10.2.1-6) 10.2.1 20210110, 64-bit
