# Query D1 from Remix

**Last reviewed:**  almost 3 years ago 

Query your D1 database from a Remix application.

Note

Remix is no longer recommended for new projects. For new applications, use [React Router](https://developers.cloudflare.com/workers/framework-guides/web-apps/react-router) instead. If you have an existing Remix application, consider [migrating to React Router ↗](https://reactrouter.com/upgrading/remix).

Remix is a full-stack web framework that operates on both client and server. You can query your D1 database(s) from Remix using Remix's [data loading ↗](https://remix.run/docs/en/main/guides/data-loading) API with the [useLoaderData ↗](https://remix.run/docs/en/main/hooks/use-loader-data) hook.

To set up a new Remix site on Cloudflare Pages that can query D1:

1. **Refer to [the Remix guide](https://developers.cloudflare.com/pages/framework-guides/deploy-a-remix-site/)**.
2. Bind a D1 database to your [Pages Function](https://developers.cloudflare.com/pages/functions/bindings/#d1-databases).
3. Pass the `--d1 BINDING_NAME=DATABASE_ID` flag to `wrangler dev` when developing locally. `BINDING_NAME` should match what call in your code, and `DATABASE_ID` should match the `database_id` defined in your [Wrangler configuration file](https://developers.cloudflare.com/workers/wrangler/configuration/): for example, `--d1 DB=xxxx-xxxx-xxxx-xxxx-xxxx`.

The following example shows you how to define a Remix [loader ↗](https://remix.run/docs/en/main/route/loader) that has a binding to a D1 database.

* Bindings are passed through on the `context.cloudflare.env` parameter passed to a `LoaderFunction`.
* If you configured a [binding](https://developers.cloudflare.com/pages/functions/bindings/#d1-databases) named `DB`, then you would access [D1 Workers Binding API](https://developers.cloudflare.com/d1/worker-api/prepared-statements/) methods via `context.cloudflare.env.DB`.

TypeScript

```

import type { LoaderFunction } from "@remix-run/cloudflare";

import { json } from "@remix-run/cloudflare";

import { useLoaderData } from "@remix-run/react";


interface Env {

  DB: D1Database;

}


export const loader: LoaderFunction = async ({ context, params }) => {

  let env = context.cloudflare.env as Env;


  try {

    let { results } = await env.DB.prepare("SELECT * FROM users LIMIT 5").run();

    return json(results);

  } catch (error) {

    return json({ error: "Failed to fetch users" }, { status: 500 });

  }

};


export default function Index() {

  const results = useLoaderData<typeof loader>();

  return (

    <div style={{ fontFamily: "system-ui, sans-serif", lineHeight: "1.8" }}>

      <h1>Welcome to Remix</h1>

      <div>

        A value from D1:

        <pre>{JSON.stringify(results)}</pre>

      </div>

    </div>

  );

}
