Remix with Nx

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

Create Nx Workspace

~/❯

npx create-nx-workspace acme --preset=apps

Please wait. 9 10✔ Installing dependencies with npm 11✔ Successfully created the workspace: acme. 12 13 —————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————— 14 15 16 > NX First time using Nx?

Install Nx Remix Plugin

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.

❯

nx add @nx/remix

Generate a Remix Application

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.

~/acme❯

Nx 15 and lower use @nrwl/ instead of @nx/

Build, Serve and Test your Application

  1. To build your application run:

~/acme❯

nx build myapp

1> nx run myapp:build 2 3Building Remix app in production mode... 4 5Built in 857ms 6 7 —————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————————— 8 9 > NX Successfully ran target build for project myapp (3s) 10
  1. To serve your application for use during development run:

~/acme❯

nx serve myapp

1> nx run myapp:serve 2 3💿 Building... 4💿 Rebuilt in 377ms 5Remix App Server started at http://localhost:3000 (http://192.168.0.14:3000) 6
  1. To test the application using vitest run:

~/acme❯

nx test myapp

1> nx run myapp:test 2 3 RUN v0.31.4 /Users/columferry/dev/nrwl/issues/remixguide/acme/apps/myapp 4stderr | app/routes/index.spec.ts > test > should render 5Warning: Functions are not valid as a React child.

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:

~/acme❯

nx g @nx/remix:lib login --directory=libs/login

1> NX Generating @nx/remix:library 2 3✔ What test runner should be used? · vitest 4UPDATE nx.json 5UPDATE package.json 6CREATE babel.config.json 7CREATE libs/login/project.json 8CREATE libs/login/.eslintrc.json 9CREATE libs/login/README.md 10CREATE libs/login/src/index.ts 11CREATE libs/login/tsconfig.lib.json 12CREATE libs/login/tsconfig.json 13CREATE libs/login/vite.config.ts 14CREATE libs/login/tsconfig.spec.json 15CREATE libs/login/src/lib/login.module.css 16CREATE libs/login/src/lib/login.spec.tsx 17CREATE libs/login/src/lib/login.tsx 18UPDATE tsconfig.base.json 19CREATE libs/login/src/test-setup.ts 20CREATE libs/login/src/server.ts 21
Nx 15 and lower use @nrwl/ instead of @nx/

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

apps/myapp/app/routes/index.tsx

1import { Login } from '@acme/login'; 2 3export default function Index() { 4 return ( 5 <div> 6 <Login /> 7 </div> 8 ); 9} 10

You can also run test on your library:

nx test login

Generating a Route

To generate a route for your application:

~/acme❯

nx g @nx/remix:route admin --path=apps/myapp/app/routes

1> NX Generating @nx/remix:route 2 3CREATE apps/myapp/app/routes/admin.tsx 4CREATE apps/myapp/app/styles/admin.css 5
Nx 15 and lower use @nrwl/ instead of @nx/

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:

~/acme❯

nx g @nx/remix:loader admin --path=apps/myapp/app/routes

1> NX Generating @nx/remix:loader 2 3UPDATE apps/myapp/app/routes/admin.tsx 4
Nx 15 and lower use @nrwl/ instead of @nx/
  1. Add a new file in your login lib

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

1import { json, LoaderFunctionArgs } from '@remix-run/node'; 2 3export const adminLoader = async ({ request }: LoaderFunctionArgs) => { 4 return json({ 5 message: 'Hello, world!', 6 }); 7}; 8

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

1export * from './lib/admin/admin.loader'; 2
  1. Use the loader in your apps/myapp/app/routes/admin.tsx

Replace the default loader code:

1export const loader = async ({ request }: LoaderFunctionArgs) => { 2 return json({ 3 message: 'Hello, world!', 4 }); 5}; 6

with

1import { adminLoader } from '@acme/login/server'; 2 3export const loader = adminLoader; 4
