Building Angular Apps in an Nx Monorepo

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

What are you going to learn?

  • how to create a new Angular 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 an Angular standalone app?

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

Nx CLI vs. Angular CLI

Nx evolved from being an extension of the Angular CLI to a fully standalone CLI working with multiple frameworks. As a result, adopting Nx as an Angular user is relatively straightforward. Your existing code, including builders and schematics, will still work as before, but you'll also have access to all the benefits Nx offers.

Advantages of Nx over the Angular CLI:

Here's the source code of the final result for this tutorial.

Creating a new Angular Monorepo

Create a new Angular monorepo with the following command:

~

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

1 > NX Let's create a new workspace [https://nx.dev/getting-started/intro] 2 3✔ Application name · angular-store 4✔ Which bundler would you like to use? · esbuild 5Default stylesheet format · css 6Do you want to enable Server-Side Rendering (SSR) and Static Site Generation (SSG/Prerendering)? · No 7Test runner to use for end to end (E2E) tests · cypress 8Do you want Nx Cloud to make your CI fast? · Yes 9

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

1└─ angular-monorepo 2 ├─ ... 3 ├─ apps 4 │ ├─ angular-store 5 │ │ ├─ src 6 │ │ │ ├─ app 7 │ │ │ │ ├─ app.component.css 8 │ │ │ │ ├─ app.component.html 9 │ │ │ │ ├─ app.component.spec.ts 10 │ │ │ │ ├─ app.component.ts 11 │ │ │ │ ├─ app.config.ts 12 │ │ │ │ ├─ app.routes.ts 13 │ │ │ │ └─ nx-welcome.component.ts 14 │ │ │ ├─ assets 15 │ │ │ ├─ index.html 16 │ │ │ ├─ main.ts 17 │ │ │ ├─ styles.css 18 │ │ │ └─ test-setup.ts 19 │ │ ├─ eslintrc.json 20 │ │ ├─ jest.config.ts 21 │ │ ├─ project.json 22 │ │ ├─ tsconfig.app.json 23 │ │ ├─ tsconfig.editor.json 24 │ │ ├─ tsconfig.json 25 │ │ └─ tsconfig.spec.json 26 │ └─ angular-store-e2e 27 │ └─ ... 28 ├─ nx.json 29 ├─ tsconfig.base.json 30 └─ package.json 31

The setup includes..

  • a new Angular application (apps/angular-store/)
  • a Cypress based set of e2e tests (apps/angular-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/angular-store/project.json file contains settings that are specific to the angular-store project. We'll examine that file more in the next section.

Serving the App

To serve your new Angular application, just run:

nx serve angular-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": "angular-store", 3 ... 4 "targets": { 5 "build": { ... }, 6 "serve": { ... }, 7 "extract-i18n": { ... }, 8 "lint": { ... }, 9 "test": { ... }, 10 "serve-static": { ... }, 11 }, 12} 13

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

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

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.
  • 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/angular plugin provides, run the following command and inspect the output:

angular-monorepo

npx nx list @nx/angular

1 2 > NX Capabilities in @nx/angular: 3 4 GENERATORS 5 6 add-linting : Adds linting configuration to an Angular project. 7 application : Creates an Angular application. 8 component : Generate an Angular Component. 9 component-cypress-spec : Creates a Cypress spec for a UI component that has a story. 10 component-story : Creates a stories.ts file for a component. 11 component-test : Creates a cypress component test file for a component. 12 convert-tslint-to-eslint : Converts a project from TSLint to ESLint. 13 init : Initializes the `@nrwl/angular` plugin. 14 library : Creates an Angular library. 15 library-secondary-entry-point : Creates a secondary entry point for an Angular publishable library. 16 remote : Generate a Remote Angular Module Federation Application. 17 move : Moves an Angular application or library to another folder within the workspace and updates the project configuration. 18 // etc... 19 20 EXECUTORS/BUILDERS 21 22 delegate-build : Delegates the build to a different target while supporting incremental builds. 23 ng-packagr-lite : Builds a library with support for incremental builds. 24This executor is meant to be used with buildable libraries in an incremental build scenario. It is similar to the `@nrwl/angular:package` executor but with some key differences: 25- It doesn't run `ngcc` automatically (`ngcc` needs to be run separately beforehand if needed, this can be done in a `postinstall` hook on `package.json`). 26- It only produces ESM2020 bundles. 27- It doesn't generate package exports in the `package.json`. 28 package : Builds and packages an Angular library producing an output following the Angular Package Format (APF) to be distributed as an NPM package. 29This executor is similar to the `@angular-devkit/build-angular:ng-packagr` with additional support for incremental builds. 30 // etc... 31
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.

angular-monorepo

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

1> NX Generating @nx/angular:application 2 3✔ Would you like to configure routing for this application? (y/N) · false 4✔ Would you like to use Standalone Components? (y/N) · true 5CREATE apps/inventory/project.json 6CREATE apps/inventory/src/assets/.gitkeep 7CREATE apps/inventory/src/favicon.ico 8CREATE apps/inventory/src/index.html 9CREATE apps/inventory/src/styles.css 10CREATE apps/inventory/tsconfig.app.json 11CREATE apps/inventory/tsconfig.editor.json 12CREATE apps/inventory/tsconfig.json 13CREATE apps/inventory/src/app/app.component.css 14CREATE apps/inventory/src/app/app.component.html 15CREATE apps/inventory/src/app/app.component.spec.ts 16CREATE apps/inventory/src/app/app.component.ts 17CREATE apps/inventory/src/app/app.config.ts 18CREATE apps/inventory/src/app/nx-welcome.component.ts 19CREATE apps/inventory/src/main.ts 20CREATE apps/inventory/.eslintrc.json 21CREATE apps/inventory/jest.config.ts 22CREATE apps/inventory/src/test-setup.ts 23CREATE apps/inventory/tsconfig.spec.json 24CREATE apps/inventory-e2e/cypress.config.ts 25CREATE apps/inventory-e2e/src/e2e/app.cy.ts 26CREATE apps/inventory-e2e/src/fixtures/example.json 27CREATE apps/inventory-e2e/src/support/app.po.ts 28CREATE apps/inventory-e2e/src/support/commands.ts 29CREATE apps/inventory-e2e/src/support/e2e.ts 30CREATE apps/inventory-e2e/tsconfig.json 31CREATE apps/inventory-e2e/project.json 32CREATE apps/inventory-e2e/.eslintrc.json 33 34NOTE: The "dryRun" flag means no changes were made. 35
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/angular:app inventory --directory=apps/inventory

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

Sharing Code with Local Libraries

When you develop your Angular 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└─ angular-monorepo 2 ├─ ... 3 ├─ apps 4 │ └─ angular-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 Angular library generator:

1nx g @nx/angular:library products --directory=libs/products --standalone 2nx g @nx/angular:library orders --directory=libs/orders --standalone 3nx g @nx/angular:library shared-ui --directory=libs/shared/ui --standalone 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└─ angular-monorepo 2 ├─ ... 3 ├─ apps 4 ├─ libs 5 │ ├─ products 6 │ │ ├─ ... 7 │ │ ├─ project.json 8 │ │ ├─ src 9 │ │ │ ├─ index.ts 10 │ │ │ ├─ test-setup.ts 11 │ │ │ └─ lib 12 │ │ │ └─ products 13 │ │ ├─ tsconfig.json 14 │ │ ├─ tsconfig.lib.json 15 │ │ └─ tsconfig.spec.json 16 │ ├─ orders 17 │ │ ├─ ... 18 │ │ ├─ project.json 19 │ │ ├─ src 20 │ │ │ ├─ index.ts 21 │ │ │ └─ ... 22 │ │ └─ ... 23 │ └─ shared 24 │ └─ ui 25 │ ├─ ... 26 │ ├─ project.json 27 │ ├─ src 28 │ │ ├─ index.ts 29 │ │ └─ ... 30 │ └─ ... 31 ├─ ... 32

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 Angular 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 "@angular-monorepo/orders": ["libs/orders/src/index.ts"], 6 "@angular-monorepo/products": ["libs/products/src/index.ts"], 7 "@angular-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 Angular application. As an example, let's create and expose a ProductListComponent component from our libs/products library. Either create it by hand or run

nx g @nx/angular:component product-list --directory=libs/products/src/lib/product-list --nameAndDirectoryFormat=as-provided --standalone --export

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 Angular application.

libs/products/src/lib/product-list/product-list.component.html
1<p>product-list works!</p> 2

Make sure the ProductListComponent is exported via the index.ts file of our products library and is listed in the exports of the ProductsModule. 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/products/products.component'; 2 3export * from './lib/product-list/product-list.component'; 4

We're ready to import it into our main application now. First (if you haven't already), let's set up the Angular router. Configure it in the app.config.ts.

apps/angular-store/src/app/app.config.ts
1import { ApplicationConfig } from '@angular/core'; 2import { 3 provideRouter, 4 withEnabledBlockingInitialNavigation, 5} from '@angular/router'; 6import { appRoutes } from './app.routes'; 7 8export const appConfig: ApplicationConfig = { 9 providers: [provideRouter(appRoutes, withEnabledBlockingInitialNavigation())], 10}; 11

And in app.component.html:

apps/angular-store/src/app/app.component.html
1<router-outlet></router-outlet> 2

Then we can add the ProductListComponent component to our app.routes.ts and render it via the routing mechanism whenever a user hits the /products route.

apps/angular-store/src/app/app.routes.ts
1import { Route } from '@angular/router'; 2import { NxWelcomeComponent } from './nx-welcome.component'; 3 4export const appRoutes: Route[] = [ 5 { 6 path: '', 7 component: NxWelcomeComponent, 8 pathMatch: 'full', 9 }, 10 { 11 path: 'products', 12 loadComponent: () => 13 import('@angular-monorepo/products').then((m) => m.ProductListComponent), 14 }, 15]; 16

Serving your app (nx serve angular-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 OrderListComponent in libs/orders and export it in the corresponding index.ts file
  • import it into the app.routes.ts and render it via the routing mechanism whenever a user hits the /orders route

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

apps/angular-store/src/app/app.routes.ts
1import { Route } from '@angular/router'; 2import { NxWelcomeComponent } from './nx-welcome.component'; 3 4export const appRoutes: Route[] = [ 5 { 6 path: '', 7 component: NxWelcomeComponent, 8 pathMatch: 'full', 9 }, 10 { 11 path: 'products', 12 loadComponent: () => 13 import('@angular-monorepo/products').then((m) => m.ProductListComponent), 14 }, 15 { 16 path: 'orders', 17 loadComponent: () => 18 import('@angular-monorepo/orders').then((m) => m.OrderListComponent), 19 }, 20]; 21

Let's also show products in the inventory app.

apps/inventory/src/app/app.component.ts
1import { Component } from '@angular/core'; 2import { ProductListComponent } from '@angular-monorepo/products'; 3 4@Component({ 5 standalone: true, 6 imports: [ProductListComponent], 7 selector: 'angular-monorepo-root', 8 templateUrl: './app.component.html', 9 styleUrls: ['./app.component.css'], 10}) 11export class AppComponent { 12 title = 'inventory'; 13} 14
apps/inventory/src/app/app.component.html
1<angular-monorepo-product-list></angular-monorepo-product-list> 2

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.

Loading...

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 Angular 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 angular-store # runs the tests for angular-store 2nx lint inventory # runs the linter on inventory 3nx e2e angular-store-e2e # runs e2e tests for the angular-store 4

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

nx run-many -t test lint e2e

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.

angular-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 angular-store:lint [existing outputs match the cache, left as is] 4 ✔ nx run angular-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.component.html
1<p>product-list works!</p> 2<p>This is a change. 👋</p> 3

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, angular-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

Loading...

Building the Apps for Deployment

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

angular-monorepo

npx nx run-many -t build

1> NX Generating @nx/angular:component 2 3CREATE libs/orders/src/lib/order-list/order-list.component.css 4CREATE libs/orders/src/lib/order-list/order-list.component.html 5CREATE libs/orders/src/lib/order-list/order-list.component.spec.ts 6CREATE libs/orders/src/lib/order-list/order-list.component.ts 7UPDATE libs/orders/src/index.ts 8❯ nx run-many -t build 9 10 ✔ nx run inventory:build:production (7s) 11 ✔ nx run angular-store:build:production (7s) 12 13 ——————————————————————————————————————————————————————————————————————— 14 15 > NX Successfully ran target build for 2 projects (7s) 16
Nx 15 and lower use @nrwl/ instead of @nx/

All the required files will be placed in dist/apps/angular-store and dist/apps/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/angular-store/project.json
1{ 2 "targets": { 3 "deploy": { 4 "dependsOn": "build", 5 "command": "netlify deploy --dir=dist/angular-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 angular-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.component.ts file and import the OrderListComponent from the orders project:

libs/products/src/lib/product-list/product-list.component.ts
1import { Component } from '@angular/core'; 2import { CommonModule } from '@angular/common'; 3 4// This import is not allowed 👇 5import { OrderListComponent } from '@angular-monorepo/orders'; 6 7@Component({ 8 selector: 'angular-monorepo-product-list', 9 standalone: true, 10 imports: [CommonModule], 11 templateUrl: './product-list.component.html', 12 styleUrls: ['./product-list.component.css'], 13}) 14export class ProductListComponent {} 15

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:

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
