Monorepo Management with Nx

Managing a monorepo can streamline your development workflow by enabling shared code and consistent tooling across multiple projects. Nx is a powerful set of extensible dev tools for monorepo management. This guide covers setting up and using Nx for monorepo management with Angular projects.

Setting Up Nx

Install Nx globally:

npm install -g nx

Creating a New Nx Workspace

Create a new Nx workspace:

npx create-nx-workspace@latest

Follow the prompts to configure your workspace. Choose the preset that fits your needs (e.g., Angular, React).

Adding Angular Applications and Libraries

Add an Angular application to your Nx workspace:

nx g @nrwl/angular:application my-app

Add an Angular library to your Nx workspace:

nx g @nrwl/angular:library my-lib

Managing Dependencies

Import and use the library in your application:

// apps/my-app/src/app/app.module.ts
import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { MyLibModule } from '@myorg/my-lib';

import { AppComponent } from './app.component';

@NgModule({
  declarations: [AppComponent],
  imports: [BrowserModule, MyLibModule],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

Running Applications and Tests

Run the Angular application:

nx serve my-app

Run tests for the application:

nx test my-app

Run tests for the library:

nx test my-lib

Building Applications and Libraries

Build the Angular application:

nx build my-app

Build the Angular library:

nx build my-lib

Generating Components, Services, and Modules

Generate a new component in the application:

nx g @nrwl/angular:component my-component --project=my-app

Generate a new service in the library:

nx g @nrwl/angular:service my-service --project=my-lib

Using Nx Console

Install Nx Console, a visual tool for managing Nx workspaces, available as a VSCode extension:

• Open VSCode and go to the Extensions view by clicking the Extensions icon in the Sidebar.
• Search for "Nx Console" and click Install.
• Use Nx Console to generate components, services, and more visually.

Key Points

Conclusion

Managing a monorepo with Nx simplifies the development workflow by enabling shared code, consistent tooling, and streamlined processes across multiple projects. By setting up Nx, adding applications and libraries, and using Nx Console, you can enhance productivity and maintainability in your Angular projects. Happy coding!
