Deploy a Remix site

Remix Open external link is a framework that is focused on fully utilizing the power of the web. Like Cloudflare Workers, it uses modern JavaScript APIs, and it places emphasis on web fundamentals such as meaningful HTTP status codes, caching and optimizing for both usability and performance.

In this guide, you will create a new Remix application and deploy to Cloudflare Pages.

​​ Setting up a new project

Use the create-cloudflare Open external link CLI (C3) to set up a new project. C3 will create a new project directory, initiate Remix’s official setup tool, and provide the option to deploy instantly.

To use create-cloudflare to create a new Remix project, run the following command:

$ npm create cloudflare@latest my-remix-app -- --framework=remix

create-cloudflare will install additional dependencies, including the Wrangler CLI and any necessary adapters, and ask you setup questions.

After setting up your project, change the directory and render your project by running the following command:

# choose Cloudflare Pages
$ cd my-remix-app
$ npm run dev

​​ Before you continue

All of the framework guides assume you already have a fundamental understanding of Git Open external link . If you are new to Git, refer to this summarized Git handbook Open external link on how to set up Git on your local machine.

If you clone with SSH, you must generate SSH keys Open external link on each computer you use to push or pull from GitHub.

Refer to the GitHub documentation Open external link and Git documentation Open external link for more information.

​​ Create a GitHub repository

Create a new GitHub repository by visiting repo.new Open external link . After creating a new repository, go to your newly created project directory to prepare and push your local application to GitHub by running the following commands in your terminal:

$ git remote add origin https://github.com/<your-gh-username>/<repository-name>
$ git branch -M main
$ git push -u origin main

​​ Deploy with Cloudflare Pages

​​ Deploy via the create-cloudflare CLI (C3)

If you use create-cloudflare(C3) Open external link to create your new Remix project, C3 will install all dependencies needed for your project and prompt you to deploy your project via the CLI. If you deploy, your site will be live and you will be provided with a deployment URL.

​​ Deploy via the Cloudflare dashboard

1. Log in to the Cloudflare dashboard Open external link and select your account.
2. In Account Home, select Workers & Pages > Create application > Pages > Connect to Git.
3. Select the new GitHub repository that you created and, in the Set up builds and deployments section, provide the following information:

After configuring your site, you can begin your first deploy. You should see Cloudflare Pages installing npm, your project dependencies, and building your site before deploying it.

After deploying your site, you will receive a unique subdomain for your project on *.pages.dev. Every time you commit new code to your Remix site, Cloudflare Pages will automatically rebuild your project and deploy it. You will also get access to preview deployments on new pull requests, so you can preview how changes look to your site before deploying them to production.

​​ Create and add a binding to your Remix application

To add a binding to your Remix application, refer to Bindings. A binding allows your application to interact with Cloudflare developer products, such as KV namespaces, Durable Objects, R2 storage buckets, and D1 databases.

​​ Binding resources to your Remix application

To access bound resources within a Remix application, you need to configure a Remix loader function Open external link .

The following example uses a KV namespace called PRODUCTS_KV bound to a Pages Function. The PRODUCTS_KV binding is accessible on the context parameter passed to a LoaderFunction as context.env.<BINDING_NAME>.

The following example shows a Remix LoaderFunction accessing a KV namespace in Remix:

app/routes/products/$productId.tsx
import type { LoaderArgs } from "@remix-run/cloudflare";
import { json } from "@remix-run/cloudflare";
import { useLoaderData } from "@remix-run/react";

// Define the bindings associated with our Function
// so that they are typed
interface Env {
  PRODUCTS_KV: KVNamespace;
}

export const loader: LoaderFunction = async ({
  context,
  params,
}) => {
  // Bindings are accessible on context.env
  let env = context.env as Env
  return json(
    await env.PRODUCTS_KV.get<{ name: string }>(`product-${params.productId}`, {
      type: "json",
    })
  );
};

export default function Product() {
  const product = useLoaderData<typeof loader>();

  if (!product) throw new Response(null, { status: 404 })

  return (
    <div>
      <p>Product</p>
      {product.name}
      <p>Products</p>
      {/* ... */}
    </div>
  );
}

Refer to the Remix documentation Open external link to learn more about data loading within a Remix application.

​​ Durable Objects

Accessing Durable Objects bindings from within Cloudflare Pages requires a separate Worker function to define the Durable Objects class.

export const loader = async ({ context, params }: LoaderArgs) => {
  const id = context.PRODUCTS_DO.idFromName(params.productId);
  const stub = context.PRODUCTS_DO.get(id);
  const response = await stub.fetch(request);
  const data = (await response.json()) as { name: string };
  return json(data);
};

Refer to the Durable Objects documentation to learn about deploying a Durable Object.
