Remix with Nx	Learn how to create, build, serve, and test Remix applications within an Nx workspace, leveraging Nx's powerful tooling for modern web development.

{% callout type="warning" title="The future of Remix is React Router" %} Remix has announced its transition to React Router. The @nx/remix plugin is based on Remix v2 and is incompatible with the latest version of React Router unless you upgrade your Remix application. In the future, the @nx/remix plugin will be deprecated in favor of the @nx/react/router plugin. If you are starting a new project, we recommend using the @nx/react/router plugin instead.

For an example of how to use React Router with Nx, see the React Router with Nx recipe. {% /callout %}

Remix with Nx

In this recipe, we'll show you how to create a Remix application with Nx.

Create Nx Workspace

NX   Let's create a new workspace [https://nx.dev/getting-started/intro]

✔ Which CI provider would you like to use? · skip
✔ Would you like remote caching to make your build faster? · skip

Install Nx Remix Plugin

{% callout type="note" title="Keep Nx Package Versions In Sync" %} Make sure to install the @nx/remix version that is on the same minor version as the nx version in your repository. If the version numbers get out of sync, you can encounter some difficult to debug errors. You can fix Nx version mismatches with this recipe. {% /callout %}

nx add @nx/remix

Generate a Remix Application

Build, Serve and Test your Application

1. To build your application run:

> nx run myapp:build

Building Remix app in production mode...

Built in 857ms

2. To serve your application for use during development run:

> nx run myapp:dev

💿 Rebuilt in 377ms

3. To test the application using vitest run:

> nx run myapp:test

Generating an Nx Library

When developing your application, it often makes sense to split your codebase into smaller more focused libraries.

To generate a library to use in your Remix application run:

NX  Generating @nx/remix:library

✔ What test runner should be used? · vitest
UPDATE nx.json
UPDATE package.json
CREATE babel.config.json
CREATE libs/login/project.json
CREATE libs/login/.eslintrc.json
CREATE libs/login/README.md
CREATE libs/login/src/index.ts
CREATE libs/login/tsconfig.lib.json
CREATE libs/login/tsconfig.json
CREATE libs/login/vite.config.ts
CREATE libs/login/tsconfig.spec.json
CREATE libs/login/src/lib/login.module.css
CREATE libs/login/src/lib/login.spec.tsx
CREATE libs/login/src/lib/login.tsx
UPDATE tsconfig.base.json
CREATE libs/login/src/test-setup.ts
CREATE libs/login/src/server.ts

You can then use the library by importing one of the exports into your application:

apps/myapp/app/routes/index.tsx

import { Login } from '@acme/login';

export default function Index() {
  return (
    <div>
      <Login />
    </div>
  );
}

You can also run test on your library:

nx test login

Generating a Route

To generate a route for your application:

NX  Generating @nx/remix:route

CREATE apps/myapp/app/routes/admin.tsx
CREATE apps/myapp/app/styles/admin.css

Using a loader from your Library

To use a Route Loader where the logic lives in your library, follow the steps below.

1. Generate a loader for your route:

NX  Generating @nx/remix:loader

UPDATE apps/myapp/app/routes/admin.tsx

2. Add a new file in your login lib

libs/login/src/lib/admin/admin.loader.ts

import { json, LoaderFunctionArgs } from '@remix-run/node';

export const adminLoader = async ({ request }: LoaderFunctionArgs) => {
  return json({
    message: 'Hello, world!',
  });
};

Export the function from the libs/login/src/server.ts file:

export * from './lib/admin/admin.loader';

3. Use the loader in your apps/myapp/app/routes/admin.tsx

Replace the default loader code:

export const loader = async ({ request }: LoaderFunctionArgs) => {
  return json({
    message: 'Hello, world!',
  });
};

with

import { adminLoader } from '@acme/login/server';

export const loader = adminLoader;
