Building React Apps in an Nx Monorepo

In this tutorial you'll learn how to use React with Nx in a monorepo (integrated) setup.

What are you going to learn?

  • how to create a new React application
  • how to run a single task (i.e. serve your app) or run multiple tasks in parallel
  • how to leverage code generators to scaffold components
  • how to modularize your codebase and impose architectural constraints for better maintainability
Looking for a React standalone app?

Note, this tutorial sets up a repo with applications and libraries in their own subfolders. If you are looking for a React standalone app setup then check out our React standalone app tutorial.

Why Use an Integrated Monorepo?

An integrated monorepo is a repository configured with a set of features that work together toward the goal of allowing developers to focus on building features rather than the configuration, coordination and maintenance of the tooling in the repo.

You'll notice that instead of using npm/yarn/pnpm workspaces, projects within the repository are linked using typescript path aliases that are defined in the tsconfig.base.json file. Also, since we're creating projects using Nx plugin generators, all new projects come preconfigured with useful tools like Prettier, ESLint and Jest.

Nx Plugins are optional packages that extend the capabilities of Nx, catering to various specific technologies. For instance, we have plugins tailored to React (e.g., @nx/react), Vite (@nx/vite), Cypress (@nx/cypress), and more. These plugins offer additional features, making your development experience more efficient and enjoyable when working with specific tech stacks.

Creating a new React Monorepo

Create a new React monorepo with the following command:

~❯

npx create-nx-workspace@latest react-monorepo --preset=react-monorepo

1 NX Let's create a new workspace [https://nx.dev/getting-started/intro] 2 3✔ Application name · react-store 4✔ Which bundler would you like to use? · vite 5✔ Test runner to use for end to end (E2E) tests · cypress 6✔ Default stylesheet format · css 7✔ Do you want Nx Cloud to make your CI fast? · Yes 8

Let's name the initial application react-store. In this tutorial we're going to use vite as a bundler, cypress for e2e tests and css for styling. The above command generates the following structure:

1└─ react-monorepo 2 ├─ ... 3 ├─ apps 4 │ ├─ react-store 5 │ │ ├─ public 6 │ │ │ └─ ... 7 │ │ ├─ src 8 │ │ │ ├─ app 9 │ │ │ │ ├─ app.module.css 10 │ │ │ │ ├─ app.spec.tsx 11 │ │ │ │ ├─ app.tsx 12 │ │ │ │ └─ nx-welcome.tsx 13 │ │ │ ├─ assets 14 │ │ │ ├─ main.tsx 15 │ │ │ └─ styles.css 16 │ │ ├─ index.html 17 │ │ ├─ project.json 18 │ │ ├─ tsconfig.app.json 19 │ │ ├─ tsconfig.json 20 │ │ ├─ tsconfig.spec.json 21 │ │ └─ vite.config.ts 22 │ └─ react-store-e2e 23 │ └─ ... 24 ├─ nx.json 25 ├─ tsconfig.base.json 26 └─ package.json 27

The setup includes..

  • a new React application (apps/react-store/)
  • a Cypress based set of e2e tests (apps/react-store-e2e/)
  • Prettier preconfigured
  • ESLint preconfigured
  • Jest preconfigured

Typically, an integrated Nx workspace places application projects in the apps folder and library projects in the libs folder. Applications are encouraged to be as light-weight as possible so that more code is pushed into libraries and can be reused in other projects. This folder structure is just a suggestion and can be modified to suit your organization's needs.

The nx.json file contains configuration settings for Nx itself and global default settings that individual projects inherit. The apps/react-store/project.json file contains settings that are specific to the react-store project. We'll examine that file more in the next section.

Serving the App

To serve your new React application, just run:

❯

nx serve react-store

Your application should be served at http://localhost:4200.

Nx uses the following syntax to run tasks:

Syntax for Running Tasks in Nx

All targets, such as serve, build, test or your custom ones, are defined in the project.json file.

1{ 2 "name": "react-store", 3 ... 4 "targets": { 5 "serve": { ... }, 6 "build": { ... }, 7 "preview": { ... }, 8 "test": { ... }, 9 "lint": { ... }, 10 "serve-static": { ... }, 11 }, 12} 13

Each target contains a configuration object that tells Nx how to run that target.

1{ 2 "name": "react-store", 3 ... 4 "targets": { 5 "serve": { 6 "executor": "@nx/vite:dev-server", 7 "defaultConfiguration": "development", 8 "options": { 9 "buildTarget": "react-store:build" 10 }, 11 "configurations": { 12 "development": { 13 "buildTarget": "react-store:build:development", 14 "hmr": true 15 }, 16 "production": { 17 "buildTarget": "react-store:build:production", 18 "hmr": false 19 } 20 } 21 }, 22 ... 23 }, 24} 25
Nx 15 and lower use @nrwl/ instead of @nx/

The most critical parts are:

  • executor - this is of the syntax <plugin>:<executor-name>, where the plugin is an NPM package containing an Nx Plugin and <executor-name> points to a function that runs the task. In this case, the @nx/vite plugin contains the dev-server executor which serves the React app using Vite.
  • options - these are additional properties and flags passed to the executor function to customize it

Learn more about how to run tasks with Nx. We'll revisit running tasks later in this tutorial.

Adding Another Application

Nx plugins usually provide generators that allow you to easily scaffold code, configuration or entire projects. To see what capabilities the @nx/react plugin provides, run the following command and inspect the output:

react-monorepo❯

npx nx list @nx/react

1 2 NX Capabilities in @nx/react: 3 4 GENERATORS 5 6 init : Initialize the `@nrwl/react` plugin. 7 application : Create a React application. 8 library : Create a React library. 9 component : Create a React component. 10 redux : Create a Redux slice for a project. 11 storybook-configuration : Set up storybook for a React app or library. 12 component-story : Generate storybook story for a React component 13 stories : Create stories/specs for all components declared in an app or library. 14 component-cypress-spec : Create a Cypress spec for a UI component that has a story. 15 hook : Create a hook. 16 cypress-component-configuration : Setup Cypress component testing for a React project 17 component-test : Generate a Cypress component test for a React component 18 setup-tailwind : Set up Tailwind configuration for a project. 19 setup-ssr : Set up SSR configuration for a project. 20 host : Generate a host react application 21 remote : Generate a remote react application 22 23 EXECUTORS/BUILDERS 24 25 module-federation-dev-server : Serve a host or remote application. 26 module-federation-ssr-dev-server : Serve a host application along with it's known remotes. 27
Nx 15 and lower use @nrwl/ instead of @nx/
Prefer a more visual UI?

If you prefer a more integrated experience, you can install the "Nx Console" extension for your code editor. It has support for VSCode, IntelliJ and ships a LSP for Vim. Nx Console provides autocompletion support in Nx configuration files and has UIs for browsing and running generators.

More info can be found in the integrate with editors article.

Run the following command to generate a new inventory application. Note how we append --dry-run to first check the output.

react-monorepo❯

npx nx g @nx/react:app inventory --directory=apps/inventory --dry-run

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

As you can see, it generates a new application in the apps/inventory/ folder. Let's actually run the generator by removing the --dry-run flag.

❯

npx nx g @nx/react:app inventory --directory=apps/inventory

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

Sharing Code with Local Libraries

When you develop your React application, usually all your logic sits in the app folder. Ideally separated by various folder names which represent your "domains". As your app grows, however, the app becomes more and more monolithic and the code is unable to be shared with other applications.

1└─ react-monorepo 2 ├─ ... 3 ├─ apps 4 │ └─ react-store 5 │ ├─ ... 6 │ ├─ src 7 │ │ ├─ app 8 │ │ │ ├─ products 9 │ │ │ ├─ cart 10 │ │ │ ├─ ui 11 │ │ │ ├─ ... 12 │ │ │ └─ app.tsx 13 │ │ ├─ ... 14 │ │ └─ main.tsx 15 │ ├─ ... 16 │ └─ project.json 17 ├─ nx.json 18 ├─ ... 19

Nx allows you to separate this logic into "local libraries". The main benefits include

  • better separation of concerns
  • better reusability
  • more explicit "APIs" between your "domain areas"
  • better scalability in CI by enabling independent test/lint/build commands for each library
  • better scalability in your teams by allowing different teams to work on separate libraries

Creating Local Libraries

Let's assume our domain areas include products, orders and some more generic design system components, called ui. We can generate a new library for each of these areas using the React library generator:

1nx g @nx/react:library products --directory=libs/products --unitTestRunner=vitest --bundler=none 2nx g @nx/react:library orders --directory=libs/orders --unitTestRunner=vitest --bundler=none 3nx g @nx/react:library shared-ui --directory=libs/shared/ui --unitTestRunner=vitest --bundler=none 4
Nx 15 and lower use @nrwl/ instead of @nx/

Note how we type out the full path in the directory flag to place the libraries into a subfolder. You can choose whatever folder structure you like to organize your projects. If you change your mind later, you can run the move generator to move a project to a different folder.

Running the above commands should lead to the following directory structure:

1└─ react-monorepo 2 ├─ ... 3 ├─ apps 4 ├─ libs 5 │ ├─ products 6 │ │ ├─ ... 7 │ │ ├─ project.json 8 │ │ ├─ src 9 │ │ │ ├─ index.ts 10 │ │ │ └─ lib 11 │ │ │ ├─ products.spec.ts 12 │ │ │ └─ products.ts 13 │ │ ├─ tsconfig.json 14 │ │ ├─ tsconfig.lib.json 15 │ │ ├─ tsconfig.spec.json 16 │ │ └─ vite.config.ts 17 │ ├─ orders 18 │ │ ├─ ... 19 │ │ ├─ project.json 20 │ │ ├─ src 21 │ │ │ ├─ index.ts 22 │ │ │ └─ ... 23 │ │ └─ ... 24 │ └─ shared 25 │ └─ ui 26 │ ├─ ... 27 │ ├─ project.json 28 │ ├─ src 29 │ │ ├─ index.ts 30 │ │ └─ ... 31 │ └─ ... 32 ├─ ... 33

Each of these libraries

  • has its own project.json file with corresponding targets you can run (e.g. running tests for just orders: nx test orders)
  • has the name you specified in the generate command; you can find the name in the corresponding project.json file
  • has a dedicated index.ts file which is the "public API" of the library
  • is mapped in the tsconfig.base.json at the root of the workspace

Importing Libraries into the React Applications

All libraries that we generate automatically have aliases created in the root-level tsconfig.base.json.

tsconfig.base.json
1{ 2 "compilerOptions": { 3 ... 4 "paths": { 5 "@react-monorepo/products": ["libs/products/src/index.ts"], 6 "@react-monorepo/orders": ["libs/orders/src/index.ts"], 7 "@react-monorepo/shared-ui": ["libs/shared/ui/src/index.ts"] 8 }, 9 ... 10 }, 11} 12

Hence we can easily import them into other libraries and our React application. As an example, let's create and expose a ProductList component from our libs/products library. Either create it by hand or run

❯

nx g @nx/react:component product-list --project=products

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

We don't need to implement anything fancy as we just want to learn how to import it into our main React application.

libs/products/src/lib/product-list/product-list.tsx
1import styles from './product-list.module.css'; 2 3/* eslint-disable-next-line */ 4export interface ProductListProps {} 5 6export function ProductList(props: ProductListProps) { 7 return ( 8 <div className={styles['container']}> 9 <h1>Welcome to ProductList!</h1> 10 </div> 11 ); 12} 13 14export default ProductList; 15

Make sure the ProductList is exported via the index.ts file of our products library. This is our public API with the rest of the workspace. Only export what's really necessary to be usable outside the library itself.

libs/products/src/index.ts
1export * from './lib/product-list/product-list'; 2

We're ready to import it into our main application now. First (if you haven't already), let's set up React Router.

❯

npm add react-router-dom

Configure it in the main.tsx.

apps/react-store/src/main.tsx
1import { StrictMode } from 'react'; 2import { BrowserRouter } from 'react-router-dom'; 3import ReactDOM from 'react-dom/client'; 4 5import App from './app/app'; 6 7const root = ReactDOM.createRoot( 8 document.getElementById('root') as HTMLElement 9); 10 11root.render( 12 <StrictMode> 13 <BrowserRouter> 14 <App /> 15 </BrowserRouter> 16 </StrictMode> 17); 18

Then we can import the ProductList component into our app.tsx and render it via the routing mechanism whenever a user hits the /products route.

apps/react-store/src/app/app.tsx
1import { Route, Routes } from 'react-router-dom'; 2 3// importing the component from the library 4import { ProductList } from '@react-monorepo/products'; 5 6function Home() { 7 return <h1>Home</h1>; 8} 9 10export function App() { 11 return ( 12 <Routes> 13 <Route path="/" element={<Home />}></Route> 14 <Route path="/products" element={<ProductList />}></Route> 15 </Routes> 16 ); 17} 18 19export default App; 20

Serving your app (nx serve react-store) and then navigating to /products should give you the following result:

products route

Let's apply the same for our orders library.

  • generate a new component OrderList in libs/orders and export it in the corresponding index.ts file
  • import it into the app.tsx and render it via the routing mechanism whenever a user hits the /orders route

In the end, your app.tsx should look similar to this:

apps/react-store/src/app/app.tsx
1import { Route, Routes } from 'react-router-dom'; 2import { ProductList } from '@react-monorepo/products'; 3import { OrderList } from '@react-monorepo/orders'; 4 5function Home() { 6 return <h1>Home</h1>; 7} 8 9export function App() { 10 return ( 11 <Routes> 12 <Route path="/" element={<Home />}></Route> 13 <Route path="/products" element={<ProductList />}></Route> 14 <Route path="/orders" element={<OrderList />}></Route> 15 </Routes> 16 ); 17} 18 19export default App; 20

Let's also show products in the inventory app.

apps/inventory/src/app/app.tsx
1import { ProductList } from '@react-monorepo/products'; 2 3export function App() { 4 return <ProductList />; 5} 6 7export default App; 8

Visualizing your Project Structure

Nx automatically detects the dependencies between the various parts of your workspace and builds a project graph. This graph is used by Nx to perform various optimizations such as determining the correct order of execution when running tasks like nx build, identifying affected projects and more. Interestingly you can also visualize it.

Just run:

❯

nx graph

You should be able to see something similar to the following in your browser.

Notice how shared-ui is not yet connected to anything because we didn't import it in any of our projects.

Exercise for you: change the codebase such that shared-ui is used by orders and products. Note: you need to restart the nx graph command to update the graph visualization or run the CLI command with the --watch flag.

Testing and Linting - Running Multiple Tasks

Our current setup doesn't just come with targets for serving and building the React application, but also has targets for unit testing, e2e testing and linting. Again, these are defined in the project.json file. We can use the same syntax as before to run these tasks:

1nx test react-store # runs the tests for react-store 2nx lint inventory # runs the linter on inventory 3nx e2e react-store-e2e # runs e2e tests for the react-store 4

More conveniently, we can also run tasks in parallel using the following syntax:

❯

nx run-many -t test

Caching

One thing to highlight is that Nx is able to cache the tasks you run.

Note that all of these targets are automatically cached by Nx. If you re-run a single one or all of them again, you'll see that the task completes immediately. In addition, (as can be seen in the output example below) there will be a note that a matching cache result was found and therefore the task was not run again.

react-monorepo❯

nx run-many -t test lint e2e

1 2 ✔ nx run e2e:lint [existing outputs match the cache, left as is] 3 ✔ nx run react-store:lint [existing outputs match the cache, left as is] 4 ✔ nx run react-store:test [existing outputs match the cache, left as is] 5 ✔ nx run e2e:e2e [existing outputs match the cache, left as is] 6 7 —————————————————————————————————————————————————————— 8 9 NX Successfully ran targets test, lint, e2e for 5 projects (54ms) 10 11 Nx read the output from the cache instead of running the command for 10 out of 10 tasks. 12

Not all tasks might be cacheable though. You can configure cacheableOperations in the nx.json file. You can also learn more about how caching works.

Testing Affected Projects

Commit your changes to git.

❯

git commit -a -m "some commit message"

And then make a small change to the products library.

libs/products/src/lib/product-list/product-list.tsx
1import styles from './product-list.module.css'; 2 3/* eslint-disable-next-line */ 4export interface ProductListProps {} 5 6export function ProductList(props: ProductListProps) { 7 return ( 8 <div className={styles['container']}> 9 <h1>Welcome to ProductList!</h1> 10 <p>This is a change. 👋</p> 11 </div> 12 ); 13} 14 15export default ProductList; 16

One of the key features of Nx in a monorepo setting is that you're able to run tasks only for projects that are actually affected by the code changes that you've made. To run the tests for only the projects affected by this change, run:

❯

nx affected -t test

Note that the unit tests were run for products, react-store and inventory, but not for orders because a change to products can not possibly break the tests for orders. In a small repo like this, there isn't a lot of time saved, but as there are more tests and more projects, this quickly becomes an essential command.

You can also see what projects are affected in the graph visualizer with;

❯

nx graph --affected

Building the Apps for Deployment

If you're ready and want to ship your applications, you can build them using

react-monorepo❯

npx nx run-many -t build

1// todo 2vite v4.3.5 building for production... 3✓ 33 libs transformed. 4dist/react-store/index.html 0.48 kB │ gzip: 0.30 kB 5dist/react-store/assets/index-e3b0c442.css 0.00 kB │ gzip: 0.02 kB 6dist/react-store/assets/index-378e8124.js 165.64 kB │ gzip: 51.63 kB 7✓ built in 496ms 8 9 —————————————————————————————————————————————————————————————————————————————————————————————————————————— 10 11 NX Successfully ran target build for project reactutorial (1s) 12

All the required files will be placed in dist/react-store and dist/inventory and can be deployed to your favorite hosting provider.

You can even create your own deploy task that sends the build output to your hosting provider.

apps/react-store/project.json
1{ 2 "targets": { 3 "deploy": { 4 "dependsOn": "build", 5 "command": "netlify deploy --dir=dist/react-store" 6 } 7 } 8} 9

Replace the command with whatever terminal command you use to deploy your site.

The "dependsOn": "build" setting tells Nx to make sure that the project's build task has been run successfully before the deploy task.

With the deploy tasks defined, you can deploy a single application with nx deploy react-store or deploy any applications affected by the current changes with:

❯

nx affected -t deploy

Imposing Constraints with Module Boundary Rules

Once you modularize your codebase you want to make sure that the libs are not coupled to each other in an uncontrolled way. Here are some examples of how we might want to guard our small demo workspace:

  • we might want to allow orders to import from shared-ui but not the other way around
  • we might want to allow orders to import from products but not the other way around
  • we might want to allow all libraries to import the shared-ui components, but not the other way around

When building these kinds of constraints you usually have two dimensions:

  • type of project: what is the type of your library. Example: "feature" library, "utility" library, "data-access" library, "ui" library
  • scope (domain) of the project: what domain area is covered by the project. Example: "orders", "products", "shared" ... this really depends on the type of product you're developing

Nx comes with a generic mechanism that allows you to assign "tags" to projects. "tags" are arbitrary strings you can assign to a project that can be used later when defining boundaries between projects. For example, go to the project.json of your orders library and assign the tags type:feature and scope:orders to it.

libs/orders/project.json
1{ 2 ... 3 "tags": ["type:feature", "scope:orders"] 4} 5

Then go to the project.json of your products library and assign the tags type:feature and scope:products to it.

libs/products/project.json
1{ 2 ... 3 "tags": ["type:feature", "scope:products"] 4} 5

Finally, go to the project.json of the shared-ui library and assign the tags type:ui and scope:shared to it.

libs/shared/ui/project.json
1{ 2 ... 3 "tags": ["type:ui", "scope:shared"] 4} 5

Notice how we assign scope:shared to our UI library because it is intended to be used throughout the workspace.

Next, let's come up with a set of rules based on these tags:

  • type:feature should be able to import from type:feature and type:ui
  • type:ui should only be able to import from type:ui
  • scope:orders should be able to import from scope:orders, scope:shared and scope:products
  • scope:products should be able to import from scope:products and scope:shared

To enforce the rules, Nx ships with a custom ESLint rule. Open the .eslintrc.base.json at the root of the workspace and add the following depConstraints in the @nx/enforce-module-boundaries rule configuration:

.eslintrc.base.json
1{ 2 ... 3 "overrides": [ 4 { 5 ... 6 "rules": { 7 "@nx/enforce-module-boundaries": [ 8 "error", 9 { 10 "enforceBuildableLibDependency": true, 11 "allow": [], 12 "depConstraints": [ 13 { 14 "sourceTag": "*", 15 "onlyDependOnLibsWithTags": ["*"] 16 }, 17 { 18 "sourceTag": "type:feature", 19 "onlyDependOnLibsWithTags": ["type:feature", "type:ui"] 20 }, 21 { 22 "sourceTag": "type:ui", 23 "onlyDependOnLibsWithTags": ["type:ui"] 24 }, 25 { 26 "sourceTag": "scope:orders", 27 "onlyDependOnLibsWithTags": [ 28 "scope:orders", 29 "scope:products", 30 "scope:shared" 31 ] 32 }, 33 { 34 "sourceTag": "scope:products", 35 "onlyDependOnLibsWithTags": ["scope:products", "scope:shared"] 36 }, 37 { 38 "sourceTag": "scope:shared", 39 "onlyDependOnLibsWithTags": ["scope:shared"] 40 } 41 ] 42 } 43 ] 44 } 45 }, 46 ... 47 ] 48} 49
Nx 15 and lower use @nrwl/ instead of @nx/

To test it, go to your libs/products/src/lib/product-list/product-list.tsx file and import the OrderList from the orders project:

libs/products/src/lib/product-list/product-list.tsx
1import styles from './product-list.module.css'; 2 3// This import is not allowed 👇 4import { OrderList } from '@react-monorepo/orders'; 5 6/* eslint-disable-next-line */ 7export interface ProductListProps {} 8 9export function ProductList(props: ProductListProps) { 10 return ( 11 <div className={styles['container']}> 12 <h1>Welcome to ProductList!</h1> 13 <OrderList /> 14 </div> 15 ); 16} 17 18export default ProductList; 19

If you lint your workspace you'll get an error now:

If you have the ESLint plugin installed in your IDE you should immediately see an error:

ESLint module boundary error

Learn more about how to enforce module boundaries.

Setting Up CI

Without adequate tooling, CI times tend to grow exponentially with the size of the codebase. Nx helps reduce wasted time in CI with the affected command and Nx Cloud's remote caching. Nx also efficiently parallelizes tasks across machines with Nx Cloud's distributed task execution.

To set up Nx Cloud run:

❯

nx connect

And click the link provided. You'll need to follow the instructions on the website to sign up for your account.

Then you can set up your CI with the following command:

❯

nx generate ci-workflow --ci=github

Choose your CI provider

You can choose github, circleci, azure, bitbucket-pipelines, or gitlab for the ci flag.

This will create a default CI configuration that sets up Nx Cloud to use distributed task execution. This automatically runs all tasks on separate machines in parallel wherever possible, without requiring you to manually coordinate copying the output from one machine to another.

Next Steps

Here's some more things you can dive into next:

Also, make sure you
