nx/docs/generated/packages/remix/documents/overview.md

The Nx Plugin for Remix contains executors, generators, and utilities for managing Remix applications and libraries within an Nx workspace. It provides:

• Integration with libraries such as Storybook, Jest, Vitest and Cypress.
• Generators to help scaffold code quickly, including:
  • Libraries, both internal to your codebase and publishable to npm
  • Routes
  • Loaders
  • Actions
  • Meta
• Utilities for automatic workspace refactoring.

Setting up the Remix plugin

{% callout type="note" title="Keep Nx Package Versions In Sync" %} Make sure to install the @nx/remix version that matches the version of nx 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 %}

Adding the Remix plugin to an existing Nx workspace can be done with the following:

{% tabs %} {% tab label="npm" %}

npm add -D @nx/remix

{% /tab %} {% tab label="yarn" %}

yarn add -D @nx/remix

{% /tab %} {% tab label="pnpm" %}

pnpm add -D @nx/remix

{% /tab %} {% /tabs %}

Using the Remix Plugin

Generate a Remix Application

{% callout type="note" title="Directory Flag Behavior Changes" %} The command below uses the as-provided directory flag behavior, which is the default in Nx 16.8.0. If you're on an earlier version of Nx or using the derived option, omit the --directory flag. See the as-provided vs. derived documentation for more details. {% /callout %}

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

> nx run myapp:serve

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;
